From 4 years in the future, this version of Jayz looks too young. 3/5 would not time travel again.

There actually is a difference between pushing and pulling through a resistance. But it is probably negligible in this context.

We did some testing on this in college for designing a wind tunnel. Basically, if you are pushing air through a radiator, the air is turbulent as it goes through. This means the turbulent air has to straighten out and loses more energy in the process.

However, when you are pulling air THROUGH a radiator, the air is starting from rest, so can be pulled in any direction it needs to, and the flow would be laminar.

This is also another good reason to pull air through filters, rather than push. Besides protecting the fan from dust, it is easier to pull through a filter than to push through it. At least in close range.

Nice job explaining the various configurations. I've been saying I'll water cool my next machine for about 10 years but end up air cooling each time. I found everything you said here to make perfect sense and it should be easy to understand for anyone looking to get into water cooling (like I STILL am). Thanks Jay.

I'm just about to build my very first high end pc and i love the fact that everything that I have a doubt about there's a video fom Jayz covering it. Thank u very much

[SchrottiJr]

Old video I know but I wanna throw something into the equation for people who are lazy, like me for example. Pulling fans tend to collect less dust because they pull it out through the radiator and putting it straight outta the case instead of pushing it against the radiator and making it stick there.
Also thank you Jay for making a video that I can copy and paste over and over again when I´m getting asked these kind of questions.

i would be building my first liquid cooled pc and i am watching a 5 year old video. nice

[Dakota-jeos]

I've only watched your videos for about a year, you always talk about how cringe you guys are sometimes but I never seen any trace of it. Today, that has changed. I have seen Jayztwocringe lol

Nice video. Note that the temperature of the air pulled through the radiator matters, so the one mounted on the front provides maximum cooing on the radiator but can heat up the ambient temperature inside the case. For balance cooling, mounting it on top where the hottest air are expelled is what I prefer.

Ran out of rad videos to watch where I’m from, traveled in time for this rad masterpiece. Thanks Jay!

i coulda swore that was a headphone ad.

>can't hear what your saying with headphones directly on your ears
>CAN hear the doorbell ring perfectly, no problem
wat

[TravisMohan]

can you do a video on overclocking for beginners ?

[ruffryder]

Best video on youtube of this topic.
Forget Forums, Google image searches, articles. Just watch this
Thanks to Jayz!

[YogertPC]

i LOVE the intro... i like it much better than the old one. it feels retro and just. good like

[NSPhysX]

I do like pull generally simply because over the years I have noticed that dust accumulates much less at the radiator than in push configurations every time I've done it. Anyways, Great Video! Much agreed on the Cooling Differences! :)

From 6 years in the future, this version of Jayz looks way too young. 2/5 would not time travel again.

Jay, In the world of ventilation there are some very boring formula for staiic and velocity pressure but it all boils down to this. One fan blowing is worth 3 fans sucking. That is a rule of thumb to go by . If all things were equal in our cases and they were sealed up, that's what it would take to make it work the way we want it to. And that doesn't even consider the fact of free air. Which is why we have shrouds on fans because without them we could never get the air to actually move. All we'd be doing is stirring it up. It is always easier to pressurize something than vacuum something. Your vacuum cleaner has a much bigger motor than your window fan. Your on the right track I know you understand the concepts, hopefully this helps clarify this nebulos subject.

[Adam-ltfx]

I would do pull for exhaust fans rather than push, the different in air pressure is negligible but by putting it in pull any dust build up will be on the exposed side of the radiator rather than between the fans and radiator.. and therefore easier to clean

You are the most creative advertising Youtuber I've seen so far...

"Something appears to have changed."
I run pull on my front mounted AIO in my A10-7870k SFF build for maintenance and appearance.
I can easily reach the fans from the inside if I need to take them down for any reason at all, and I can reach the rad from the outside for cleaning.
Plus you can't see the branding on the side of the rad, but you can see the fans, from the view window. If I take the front cover off, the rad's right there, giving the system a neat industrial look.
My build can run in partial passive mode, using only my single case fan to keep it cool (35c) at desktop and light loads, but peeking into the side of the case lets me see if the fans are running or if one has stopped for some reason. (I had to take one offline for repairs.)
....
Guys, why are you staring at me like that?
