TikTok Tech Tips are TERRIBLE
Chapters13
The host tests a controversial CPU cooling hack using a thermoelectric element, questioning its practicality and ultimately finding it ineffective yet entertaining, while debating whether it spreads tech misinformation.
Linus Tech Tips flags TikTok tech hacks as unreliable, debunking myths with hands-on tests and clear warnings about real-world risks.
Summary
Linus breaks down popular TikTok tech hacks on TikTok Tech Tips to show what actually works and what doesn’t. He pokes holes in DIY cooling stunts like Peltiers on Threadrippers, highlighting real limits such as 106 watts drawn and CPUs hitting ~66°C under load. Adam and Linus also test common Windows tips, like using Run to delete cache folders, and expose the misleading or dangerous nature of many quick-fix videos. The episode leans into practical guidance: avoid misused tools, don't tweak boot processor settings, and rely on proper driver-level optimizations rather than placebo tweaks. They acknowledge some tips can be harmless or even sensible, such as disabling fast startup, but emphasize understanding consequences and avoiding push-button optimizations. The duo also praises legitimate resources, like reliability history for troubleshooting and the value of a clean OS install, while calling out the average TikTok hack for lacking context. Throughout, Linus champions responsible tech teaching and points viewers toward safer, proven methods. The video closes with a light look at a few dad-focused PC tips and a nod to Squarespace for creators who want a home base for their projects.
Key Takeaways
- Peltiers as CPU coolers are largely impractical for high-end CPUs like Threadrippers; even with a large surface area, they struggle under load and can exceed safe temperatures.
- Test results showed the 1070 GPU with a CPU at around 66°C under full load and about 106 watts of draw, illustrating how far off typical TikTok hacks can be from real-world cooling needs.
- Windows tips that involve running commands from Run to delete folders are dangerous and ineffective; viewers should verify what a command does before executing it.
- Disabling startup items can reduce boot time and RAM usage, but most tweaks don’t meaningfully boost gaming FPS; driver-level optimizations and proper maintenance have a bigger impact.
- Fast startup can speed boot times but risks file system corruption and BIOS access issues; disabling it is a reasonable, well-explained tip when understood in context.
- Reliability History and other built-in Windows tools are valuable for diagnosing intermittent issues, a contrast to one-size-fits-all TikTok hacks.
- Microsoft’s and hardware vendors’ official guidance, plus a clean install if necessary, offer safer, more durable improvements than quick hacks seen on social videos.
Who Is This For?
Essential viewing for PC enthusiasts and Windows users who frequently encounter TikTok hacks and want to separate gimmicks from genuine, safe optimization techniques.

Welcome to Tik Tok, the premier source for AI slop and brain rot, and for half of us Americans, the news. But can we trust any of it? Welcome to Tech Court, Tik Tok, where I'll be trying your tech hacks and determining whether you're free to go or free to go straight to jail. The whole platform's on trial. First up is Mr. Yeester. generated from its own CPU, which honestly is working way better than I expected. Despite nothing plugged into the CPU fan pins or the chassis fan pins, not only is this giant fan still spinning, it's keeping the computer cool under 100% load at around 66°.
Well, depends what CPU you're running. How in the world is this possible? How is it possible? To see if he's a fraud, I bought the exact same model as he has. It's a tech. It is, but like TEC, a thermmoelectric cooling element. We've got a hot side that's going to come from our CPU. We've got a cold side that's going to come from this heat sink here, which will be cooled by the fan that is powered by the voltage that is generated by the hot and the cold side on either side of this Peltier module.
Yeah. So, typically you put these on top of like wood burning stoves or furnaces to help circulate the heat around the room, not to like actively cool anything. What were you thinking putting it on a Thread Ripper, sir? I think it's actually going to give it a better chance because we have way more surface area. That's got to be like a 35 watt CPU that is I don't know. I don't know, man. All right, that's enough. I'm going to give her the old splooshy splooshy. You can give her what? How much heat does it need to start spinning?
Like she's getting warm. Brother, it's peaked at 94 and I think IT Now we're cooking with electricity. This right here is a tiny fraction of the amount of surface area that a CPU like this would need in order to be cooled. Sorry. We're currently pulling 106 watts. It literally smells hot. We have not thermal throttled yet. We haven't hit proc hot. We're damn close. This is so stupid. Bear in mind that this is on a 1070. If we had a better GPU, we would be pushing our CPU harder to keep up with it. Do you want to try a full CPU load?
No. You sure? Yeah, I'm really sure. This is That's the fact that this worked at all. I say we call it a win. What's the verdict? Not guilty of spreading tech misinformation. I'm gonna do it. I'm doing it. Wait, what? He's doing it. Why are you doing that? I want to see that. I want to see. Are you sure you haven't throttled yet? Yeah, the package power is 80 W. So, it's definitely thermal throttling. It's just not being indicated by that. Ow. Why would you touch it? Cuz I wanted to know how hot it was.
Bro, it says right here how hot it is. It's on the screen. Let's turn it off before it dies. No, don't turn it off cuz this is going to be our CPU cooler for the rest of the time. Why would this be our CPU cooler for the rest of the time? Because that's all I prepared for the video. No, you prepared one other thing. You prepared this segue to our sponsor, Squarespace. Your business or brand needs a web page to act as a home base for any potential customers or clients. Squarespace has a full suite of easytouse tools to get you started.
Check them out using our link down below. All right. Baloha. What did I say wrong? It sounds like you were summoning something. I don't know. That's like a Did you know that if you press the Windows key plus R, then type this command and hit enter, you'll open the hidden Nvidia folder, then just enter both folders and delete everything inside. These are just cache files your graphics card doesn't need. This can fix random stutters, reduce lag, and even boost your FPS. You are so full of That is malicious. One, there's like multiple levels where it's wrong.
No, no, we can't. We We No, no, we can't pass judgment. We got to try it. First, we have to enter the matrix with Windows R. Hot keys. There's a scary amount of these that start with open up Windows R and run what I tell you to run. Oh, the hidden video folder. Then just enter both folders and delete everything inside. So, press control A. To be clear, it's not going to do anything. Well, you mean it's going to get rid of stutters and reduce lag and boost your FPS? No, it isn't. I'm entering all three folders for bonus points.
You said that, man. Well, there's the game running like it did before. Beautiful. Truly guilty. Rule of thumb, if something says Windows plus R and then type anything in, don't do it until you know what it does. And if they say delete a bunch of stuff, also don't just listen. Don't just take their word. One thing you'll notice across a lot of these Tik Tok hacks is that they tell you to do stuff and they give you zero explanation, which I think is a big problem. People know you can do this. Go to your desktop and create a new folder.
When renaming this folder, enter the following code, which I'll place in the captions and a pinned comment. It needs to be exactly this code that you paste as your folder name. Then press enter. You will notice that doing this changes the folder icon indicating panel. When you open it, you will see this simply all your computer settings in one place. This is nonintac has god mode. What the I'm sorry. Is the sales pitch that the control panel is god mode for Windows? 55,000 likes. Someone type it for me, please. Here's a brilliant idea. I bet you could type this a lot faster.
Wow, there. That was less work to type than whatever he did to make that folder. Okay, let's let's play around with it. Maybe we've judged it too hastily, Adam. I've got it set up now. Ah, yes. Play CDs or other media automatically. Do you think it has quick share settings? Windows to go startup options. Dude, do you remember Windows to go? I I remember the settings. I don't even remember what it is. Yeah. See, it just brings up the the modern control panel. So, he does promise that all of your settings are in here is not the case.
Many settings are in here. No, I don't I mean, I don't even think display settings are in here, which I would consider to be fairly basic. Like anything new like HDR is not going to be in here. Manage storage spaces. Okay, let me create a pool. Yeah, don't mess with that. It's honestly how I kind of wish control panel would be organized though. Yes and no. I actually am at peace with the modern one these days. It's not bad. I don't The settings menu versus the control panel. I'm talking specific control panel, but I find the settings menu has its own problems.
I find the settings menu does have issues particularly around things like audio. I also hate how deep you have to go to get to things like refresh rate, but it's still better than it used to be. To me, refresh rate is basic display. Please let me Windows, let me open two settings. Windows, you're called Windows. Tabbed. Tabbed. Maybe. Ooh. So, what's the verdict? Guilty. What's the sentence? Three rounds of Dota with a feeder. Okay. And they're long rounds. Your team does not know how to end. Oh my god. Anything that starts with someone in a hoodie at a keyboard is just Start by going to your keyboard.
Then click the Windows button plus R. Now type by going to your keyboard CPL. Click on okay. Now go to your Wi-Fi device. Then click on wireless properties. Go to the security page. Hold on. Then click on show. There's so many problems already. Is that really the fastest way to open the network control panel? Uh, no. Also, buddy, you couldn't even be arked to like edit having the window within your narrow screen recording strip. You got to like wait a second and move it over. Also, here's the crazy thing. He's using Windows 11. Do you want to see how you see your Wi-Fi password in Windows 11?
You click on the Wi-Fi. You go to the network. Oh, you have to be signed in. Give me a second. Wow, what a tech tip. Give me a second. If you're not signed in, you can't get the Wi-Fi password. Let's clarify that. You can. We did a whole video on war driving where we made a Wi-Fi password cracking van. You guys can check that out. We'll link it down below. That would actually be a tech tip that feels illegal to know. But in Windows 11, if you're connected to your network, you just go to the Wi-Fi quick settings.
You click the I and then you say Wi-Fi network password and you click show. And then you can like just scan it with your device, which is way better than whatever we're about to do. You don't need to type in the run window. unhack your hacked PC. Click on okay. This will take you to a page where you will find the list of users that have full access to your PC. Just remove any of them that you don't know and the person will no longer have access to your computer. So, my computer's hacked, but I totally have full access to an administrator account that I can use to remove the extra user accounts that the hacker made for reasons.
Every single time I hack a computer, I always make a new underprivileged user account. Guilty. 70. How powerful is your PC? Let's check it out. Go open PowerShell and type this command. If I didn't like people opening up the run window and typing in random things. I definitely don't like them doing that with PowerShell and hit enter. It will display your system performance score. Score more than eight is for high-end games. What are you talking about? Video editing and heavy. Is this the old Windows Vista system assessment? This thing still exists. Uh, apparently. And apparently they upgraded it to go to 9.9 for Windows 8.
I had no idea. Also, it was useless when it came out because they had no way of knowing how to balance that single score for every possible use case. And I got to imagine it is a way more useless today than it was back then. Guilty. I sentence him to no guey for 1 year. No guey. He has to do everything in the PowerShell. Wa! Uh-oh. PC's performance. Press Windows and R and type msconfig. Go to boot, then click on advanced options. Change the number of processors to the highest one and press control, shift, and escape.
Go to the details tab and find your game. Right click on it and change the set priority to high. Press Windows and search startup apps. Then turn off any app you do not need right when you turn on your PC. Couple things here. First of all, your computer has all of its cores regardless of what you're doing in there. Number two is I actually do not recommend playing around with process priority unless there is a specific issue that you're trying to troubleshoot. Finally, what was the last thing you did? Uh it remove startup apps. Oh, I mean, yeah, that's good.
Yeah, it's not going to boost your FPS. No, but it might reduce your startup time. Yeah. And it could reduce your RAM usage, which could, if you're like right on the edge, help with performance. I did a little bit of investigating into the boot processors. You really actually should not touch that at all. If you change your hardware configuration, it will screw a lot of things up because it's going to try and load up a 12 core configuration. And if you switch to an 8 core CPU, right, you're going to just get a blue screen, you're going to get boot looping.
It can also mess up your BIOS. That even ignores that not all processors use all of the same types of cores. For instance, Intel processors have uh P and E cores, which it uses Thread Director to dynamically work with Windows to assign the correct tasks to the correct course. So, I don't know that this would that up, but it definitely won't help. Yeah, just don't mess with it. Guilty. One day blinding stew soup that makes you blind for one day. Put the headphones on. Press the power icon in the corner then restart. Once you're in the blue screen, click on troubleshoot advance options command prompt.
Now type this commando type notepad. Then go to file and open bro this PC then the drive where the window show 32 then change all files. Look for util. Right click copy the name bro. Rename it to your man to then look for cmd next. Rename it to your man. Exit click continue. Reset back to the light and click the moment cmd open type user. Look for the user that you're using then user start press enter game and submit in the bar. Once you're in go to file this PC then drive window system 32 then look for copy and paste it in the system then rename it.
Now, guess what? Now you're through. Yes, I got my PC back, man. Bro, you have no idea how many steps Rap Tech PCs. You know what? I love the style. Have to confess, I haven't played around with user account recovery in quite a while. That might work. It's almost certainly not the least convoluted way to do it, but I had more fun than I ever have before learning about PCs. Innocent. Oh, one day grinding stew. Well, hold on. Actually, I I changed my mind. Guilty of too much charisma. Oh, one day grinding ste. Oh my god.
Get stop touching my stuff with that. Okay. All right. Jay's tech. Uh it's not literally correct but it is correctly illustrative sort of you cannot experience a higher refresh rate on a lower refresh rate display. So effectively what's been done here is multiplying the number of cursors that I'm seeing as though I had a high refresh rate monitor and I was dragging my cursor and then I was seeing the persistence of that across the trail with each refresh of the display. So that's like kind of what we're looking at here. But that's something that you that you kind of feel and experience.
It's not something that you can see like this. This is it's just motion blur. Yes, I see what they were trying to illustrate. It's just that you're not watching this TikTok on a 480 Hz monitor and you're not watching at 480 Hz. Yes. I didn't realize how many of these are from RTC tutorials. These guys were just hugely popular. Make your Windows 11 run at its maximum power. On your search bar, type view advanced system settings. Then click settings. Choose adjust for best performance and click apply. then okay just you know by doing this it will remove unnecessary items from your PC and achieving optimal performance that's fine it does not make Windows 11 run at maximum power no but what it does is it makes your PC feel a little bit more responsive so while I wish that they were honest about what you were actually doing I don't mind that tech tip it's just yeah nothing to do with what they say it is mistrial double jeopardy This is not an optimization.
Doing this is not an optimization either. This one doesn't help performance at all. And this, it just adds more overhead. Most PC tweaks don't change performance. They just give you a placebo effect. The real optimizations happens at the driver level. By default, Nvidia instric overlay background services they stay running even while you're gaming. Removing what you don't need reduces overhead and stabilizes frame pacing. Okay, maybe a little bit. It depends on what you have enabled. Like if you have for instance um Nvidia's feature where you can be continuously screen capping and then you can like rewind a little bit and capture.
Yeah. Is it called replay? I hope so. Like if you have that running, there can be situations where you're in a very graphically intensive scene and that little bit of extra overhead for running replay could cost you a little bit of performance. But from my understanding, that's something you have to enable. So if you don't know what that stuff is, it shouldn't be on video help back. Open install. Wait, am I downloading this from him? Go get it at tech powerup. Do not download it from random anywhere else. Tech powerup I trust. I appreciate at the start where he's like all of these things that we have seen in a few Tik Toks are not actually things that optimize your PC.
This is something that can have an impact and the envy clean install utility can be useful. Yes. Don't like the come to my discord and download the file for me. Verdict hung jury and stop putting it near my uh my tool chest over there. Microsoft has a setting called fast startup which is enabled by default. It's essentially just a sleep mode disguised as your PC shutting down. And this means that your PC is never fully shutting down even when you tell your PC to shut down. The feature speeds up boot times after a shutdown by saving the Windows kernel and drivers to a hibernation file rather than like fully closing everything.
This is a really solid tech tip on it just loads this saved state and skips the usual hardware initialization and reloading. This makes your boot time faster, but it can end in potential file system corruption. It can cause issues with you accessing your BIOS, and it doesn't really benefit you if you're booting from an SSD since those are fast. Anyway, here's how to disable fast startup. This is pretty solid. Yes, fast startup can cause issues. No, it doesn't usually cause issues. And if you really want to make sure that you don't have any issues, you can just do a reboot.
Fun fact, shut down will engage fast startup. A restart will not. Not guilty. and excellent hair. Crusty water cooled PC and he hasn't changed the liquid in 3 years. Yeah. So, as an influencer, I understand the need to Whoa. react to stuff. Like, I can't believe that. A computer that's still working after 3 years. Uses his PC every single day like nothing's wrong. Dad, do you have anything to say for yourself? Yes. I neglected my PC. my beautiful build. At this point, I don't know if I should be disappointed or impressed that this thing is still running.
You know what? The wheels on a that big of a case, that heavy putting get on casters. Actually, genius idea. Oh, yeah. That's a thing. That's great. This I have never seen us do. Using the data vac to empty a loop. Yeah, that's pretty smart. Do you want to try it? Yeah, sure. Hit me. Whoa. He's getting a little aggressive. Wow. Got to admit, all these years it never occurred to me to do anything other than blow on it. Wicked smart and not full of bacteria. That's a good tech tip. Verdict, not guilty. A new a new computer for your dad.
Yeah, also your dad's computer is fine. Matt's Computer Services says, "Avoid used gaming PC scams as the computer seems to be completely disconnected from the monitor, and the only thing to fix this is to manually shut the system off before turning it back on where the PC boots up like nothing ever happened. So, what's going on here?" Well, we can easily find out by clicking the Windows icon on our keyboard and typing in reliability history and selecting the best. Okay. Yeah, reliability history is a really really great tool for tracking down especially intermittent errors with your system.
It doesn't log everything. No, but it logs a lot. This is a really great video. Also, that old school cool Modmat Extreme. Nice. All of his content is that I've seen is really really well done. Really informative. Outstanding. Shout out Matt's Computer Services. guilty of being knowledgeable and awesome. You're sentenced to a free We should send him a screwdriver. Sure. Yeah, we could send him a screwdriver. Why not? We're going to send you a screwdriver. Yeah, let's go. Do you think we should maybe making more Tik Tok content? Like we need to help clean it up.
Or do you think it's in the right hands? It seems like there's good stuff. Yeah, there's good stuff. Froto's doing a great job. Also, buddy with the tech repair shop. Love him. Yeah. Uh you you seem really defeated. Are you going to be okay? No, they're there. What's on there? My feet. I have not been defeated. I thought you were just pointing to that segue.
