“Other wise” *leaf blower sound starts in the background

damn I hate cliffhangers 😢

“Make sure to adjust your fan curves so they aren’t always spinning at max speed” The PS4 engineers at Sony: “damnit I knew we forgot something”

I have only negative pressure in my PC case. Temps are good, dust is good too (it’s everywhere).

For my old tower, I just took the side panels off and parked a box fan next to it. Coolest I've ever run.

When in doubt, do the “paper test”. Place a thin piece of paper in front of fan. If paper “sticks” to fan air blowing in. If paper is “pushed” back by fan, air blowing out

Cliffhangwr like it was a Chainsawman episode.

I thought I had set my fans up wrong but it turns out that they're actually in the right way. Mission failed successfully.

I have negative air pressure in my case and it, surprisingly, is the setup that has given me the best temps. 9 exhaust fans on three radiators with one intake on the back in the lian li 011 xl.

This video helped me finally understand why positive pressure is better!! Thank you LTT

Otherwise? Finish your sentence!

I wish fan companies had rgb fans that also spun in the opposite direction so that all the fans would look pretty

I like to imagine James is reading these comments and laughing like dr evil right now 😆

Me using a window fan next to my PC

The positive pressure comment is genius; thanks for that insight!

This is literally perfect timing i just got my pc fans from Amazon

If your pc tower comes with a dust filter i think it's good to have a slight negative pressure cuz it's always good that all the hot air is taken out of the tower and allows more cold air to get sucked in

an actually useful short. thanks for the info

I never thought about the dust getting pulled in with negative pressure in the case. Good tip!

Beautifully explained, now walk me through what I need to do exactly

It seems you either overlooked, or picked the wrong alternative, in the _'Region'_ option when ordering your household fans. Those are *_Australia_*_ spec_ fans.

I normally can’t hear my fans at full tilt from their home under the desk. Only when nothing is playing through my headphones do they come through. Unlimited power for the spin gang.

I really think you guys need to go back and review this... When holding the PC fan up to the 'household' fan, you're holding the PC fan backwards. You state a moment later that the 'nice' side is the intake side which is the side you had facing the camera in that shot. So if you properly put the PC fans intake towards the household you'd see it's actually spinning clockwise as well.

I finally understand air preasure within a pc case system thank you

OTHERWISE WHAT! I have no idea what could happen!

"Are you installing your fans properly?" No, no I'm not. Because I bought my pc prebuilt

Good short vid! I prefer negative pressure with dust filters though. Almost no dust at all and certainly less than no filters + positive pressure. Also the negative pressure with exhausts at the top help the chimney-effect so you can run very low rpm with air coolers! I've tested this with 1 exhaust fan at the top/rear against 3 intake fans at the front. Taking the front fans out made the temps raise about 5°C (70 to 75), while taking the rear fan out showed 83°C. But for idle desktop stuff, I stop the rear and top fans but keep the 3 front fans at 350 rpm to only have the negative pressure + chimney-effect under load.

I've got better advise: make a riser for your case, so it is not on the floor or on your desk sucking up dust at all

NEVER! I will negative pressure my case and love it.

a real tech tips btw

One of the few times that the auto replay feature of these shorts added any value.

Am I the only one who likes going in HW info and cranking the fans to full speed so I can hear the computer becoming an airplane??

I removed all my filters and have negative pressure with all fans maxed out. I also love cleaning my pc

Negative air pressure is much better for flow/turbulence, getting way better temps, you just have to keep your desk clean and do some maintenence every few months.

It's crazy I was literally installing my fans for the first time when I opened youtube and this showed up on my feed. Great time lmao

You're the only person I've seen that has recommended positive airflow. Everyone else recommends neutral airflow

"are your fans installed correctly" no i used zip ties

Living in a simulation.......i swear lol...hours ago I looked up this information to make sure my gfs new case and fans would get the best way to set them up....

positive pressure good in pc application. Negative pressure is usually the way to expel gases from internal combustion engines

Now this is truly a tech tip

This content really should be in your OnlyFans account! 😁👍

I literally ordered my pc parts a couple of hours ago and needed exactly this.

Some older fans made by superred are standard fans but they blow the opposite direction

My molex fan: "yeah, sure. set the damn fan curves"

didnt you bust the pressure myth yourself years ago? also, some cases like NZXT H500/510 performs better with negative pressure.

I always prefer a slightly negative pressure for the best cooling at higher temps, but it really depends on your fan positioning... an exhaust next to huge openings with negative pressure would just recycle the hot air. There is no ideal scenario regarding pressure, the important thing is to know how your case works

PC fans and room fans spin the same direction in reference to airflow. If the air is coming towards you the blades spin clockwise. If they air is blowing away from you the fins are spinning counter clockwise.

The default curves on motherboards are fine. Its just a linear flop rate relationship. There are pros and cons to each curve style depending on what you want, but most people won't notice or care for those from the linear line.

I really like how the top intakes are right next to the top exhaust, making 3 of the fans essentially useless. Maybe some educational TikToks on actual air flow would be helpful instead of super basic “6-4=2=good setup”

There can be benefit to negative pressure as well, in some cases (h510 comes to mind) the main place it’s going to pull in air is through the PCIE slots which is going to give your GPU plenty of fresh cool air.

Just ordered a bunch of Noctua fans for my new build.. 4 intake and three exhaust

"Positive pressure" is other word for "dust collector".

Every fan spins counter clockwise, the only thing that differs is if you're measuring from the front or behind the fan.

This is the first time ever I hear someone recomment positive pressure

OMG I built my pc when I was 12 in a Corsair 5000d and arranged my fans exactly like this, using my common sense, and logic.

We in Australia like to call the counter-clockwise direction, 'standard spin'

I can't believe I didn't know there are arrows on my fans 😭😭 I spent so much time carefully deducting which side the fans blows, thank youuuu

The main reason for not having negative air pressure is only related to air cooling and doesn't really apply to water cooling. Negative pressure means less air molecules in the case to transfer the heat energy into. Somewhat less importantly, but more impactful over time, negative air pressure causes more dust to accumulate on the inside of the case.

You realize that depending on where you live that you have to change what direction your fan rotates based on season (to either pull hot air up in summer or cold air up in the winter)

Man, this is like taking care of a dog. Taking it on a walk daily, and bathing them daily

I do only negative pressure (=suction?) because cavitation is so awesome when gaming. ;)

i prefer slightly negative air flow. makes sure all the excess heat is pulled quicker. slightly positive air flow will hold the heat in more. slightly positive airflow will give slightly more heat diffusion, but it'll be more temperamental as there will be more hot pockets.

"PC Fans turn counter clockwise" .. *staring at my scythe fans in confusion* I beg to differ sir.

Information level: Expert

The spin in exactly the same direction lmao. Based on the direction of the airflow they are the same

The arrows really help.

They don't actually spin counter clockwise. They spin in the same direction as a normal fan based on the direction of airflow. It just depends on which side you call the "front".

This was on of the most useful Linus tech tips I've seen and it's not even one mini long! What!? 🤯

i didnt even know that household fans spun a specific way

I'm a big fan of this channel! good content!

ML120s (non-rgb) are excellent quiet fans, unless you forget to set the fan curve and they spin at MACH JESUS.

I recall way back, before rgb revolutionised pc cooling, all that cooling fans did, was suck old and well-used air in, and blow it at stuff

General rule is that positive airflow is better, but I get better temps with negative airflow, probably because it’s pulling the hot air out in a laminar way

My case has neutral air pressure since it has two intakes and two exhausts. I could tune the fans to make sure there's a little positive pressure, but I prioritize quiet operation, and my case gets dusty VERY slowly. Like, I didn't clean it in over 3 years and it still looked really nice and not gross at all, even with rgb all over it.

Every other source claims that negative pressure improves temperatures oposed to positive pressure. The dust problem is still a valid point.

Fan control is godspeed. Go hunt down the software and support that guy

According to Steve, you can't even install fans properly... 😂😂😂

This was the biggest reason for my overheating issues when I was building PCs 6years ago

I have 3 exhaust (back and top x2) and 5 intake (front x3 and bottom x2). Works great for my MSI Codex R 110 case.

Watching this left me exhausted.

Opti actually reccomends for small itx builds negative pressure to actually encourage air through mesh and stuff

It’s ok. I’m usually playing flight sim anyways so the sound of my pc blowing real loud actually makes it feel like more of a cockpit 😂

A helpful mnemonic I picked up is "faces suck", to remember what you said about how the nicest side pulls the air through.

Me: *PC turns on* yeah it’s workin.

Thanks i needed this

I have 19 fans in my case including 3 blower style. It sounds like a jet plane at idle...

“Otherwise…” AUGHHHHHH

If he has a twin hes the evil one

Remember this. You don’t need some strange fan set up to ensure your build has positive pressure. Just adjust the fan curves of your intake/exhaust fans 👍

Good video! Thanks!

Ah dang, I technically have negative pressure as I only have 1 intake but 2 exhaust. I also haven't put my side panels on in months though...

Negative can be good too, but yes lots of dust

For those who don't know if they installed right use use a piece of tissue or paper towel and see if it pushes or pulls

It's the advertising guy !!

I thought he was about to say some stupid way but that was actually useful

Household fans can spin in either direction, and should depending on what time of the year it is

"SLIGHTLY higher intake pressure" - you never want to have more than that. Temperaturewise you want a slight underpressure, ignoring the dust problem. Reasoning behind that: cold/fresh air can come into the case anywhere, warm/used air tries to go out almost always on the top. For me it is 3x front in and 3x top out and 1x back out, could add another bottom in but have no filter there.

Im pretty sure all my fans spin clockwise

When you haven't realized that fan spin direction depends on which side you're looking from 🤔👌

Yes I really am installing them properly. Thanks for asking.
