People say this series is pointless, but it's busting the myths that people have been shoving down beginners' throats for years.

5:31 you got your answer now go to sleep

Graphics card temps would have been a bonus, i would be trying to adjust the airflow to minimize temps inside the case.

for some reason I thought about my own fan configuration for like 2 minutes before I realized... My computer is air cooled... XD

what about the 2 up / down on the left pushing air flow down, and the 2 on the right 2 up and / down pushing airflow up, kinda like sucking it down and then pushing it up

the workshop is answering questions Linus answered 3+ years ago

I just want to thank you for doing all of these workshop episodes. You are putting all of the "Best Practices" of building PCs to the test, and actually giving us objective data.

Would have been interesting to have one side being in and one out, like front in and back out, so it would possible cause it to travel in a U-pattern through the radiator.

I like to place my fans on the bottom of the radiator for the looks, but as said in the video, it makes sense putting them on the top to make dust-cleaning easier.

The one irk I have with these tests is they do not seem to test (correct me if I am wrong) when the GPU is also at load heating up the air inside the case. As would that not potentially make it better to pull cooler air from outside the case? Would there be a way you could test that Luke?

You should do tests like this in a small case with bad airflow rather than in a huge case with almost infinite cooling options like the master case. Also it would have been interesting to see, which config is best for the overall temperature inside the case (GPU temp & mobo temp), assuming you'd only have the rad and one 120mm fan for ventilation (probably doesn't matter in the master case but with a small, poorly ventilated case it might make a difference)

What would happen if you have one side going in and the other out? Thinking this may maintain neutral pressure in the case.

I really appreciate you guys doing these workshop videos. They answer a lot of common questions people would have when it comes to the added features of certain computer products. They also answer a lot of the more detail-oriented questions when it comes to certain computer configurations. Especially when we don't have the ability to test it for ourselves. Definitely keep these types of videos going when possible. The only thing I would consider is testing a few more scenarios in these videos if you can. I know you guys are busy, but for this video I would have very much liked to have seen what happens when the rad is front mounted. Also in the power supply video, if you could have kept things constant for the 80 plus ratings, for example all 80 plus gold psu's, then make a separate video based only on the 80 plus ratings then that would help people get a much better understanding of power supplies as a whole as well as give you guys more content to create. I know there are a lot of different ways to test these things, but if there were a few more controls as well as a couple of added scenarios that people may be considering then these videos would be just that much better in my opinion. That's not to say it didn't answer questions I had though. It still helped a ton and that's why I felt compelled to even say anything simply because of the potential this particular series of videos have.

please place the numbers on screen, it's hard to keep track of all of yhe.m

What I keep learning from this Workshop videos is that nothing matters unless you do something really stupid like stuff your dirty laundry in your case.

I'm rebuilding my PC tomorrow with a bunch of new hardware, and one of those just so happens to be the Corsair H115i and this video helps me out a ton! Thanks Luke!

let me think of a joke. people who make this joke is a joke including me

4:14 @Luke how did you get your pants to push up through the rad???? I must try this configuration...

Lol finally a follow up to Linus's video a few years ago. I run mine in pull like you guys do and it works just fine

Cool. I am building a truck and have the radiator mounted where the spare tire was. Tilted up around 10 degrees to get air out. But almost completely flat similar to your setup. I have my fans mounted above the rad pulling UP through the rad in a effort to have any derbies stuck to the underside simply fall, be blown away when moving, or lightly pressure washed away when the fans are off. I was unsure how well this may work as it seems everyone mounts there fans below. But after seeing this I am confident it will work as intended. Thank you

could a graphics card under load producing heat affect the config that exhaust air from inside the case?

Are we going to ignore that the Ghost Stories Dub was part of that sponsorship? That dub was hilarious

Thanks. Very needed information for me just bought CorsAir Cooling.

Great vid :D Could you do some tests with rads only, without the fans? or maybe just 2 basic case airflow fans (1 back blowing out, 1 in front blowing in)?

how about the age old "order of your water cooling loop" thats always fun. maybe you could try pump>GPU>CPU>rad>res / pump>GPU>rad>CPU>res / pump>GPU>small rad>CPU>small rad>res. mix it up a bit, go pump>rad>rad>CPU>rad>GPU>res. may need a beefy pump for that one

Why didn't you monitor GPU temperatures when pulling air in to the case? I'd like to know if the reason we all exhaust our CPU's warm air out of the case has any truth behind it, since cable management didn't.

Just bought that cpu cooler and I installed it the way I thought would be most effective. Thanks LTT for saving me the trouble of having to take it out!

thank you for sharing this! i had some heating issues. this helped. TY!!

And what about the case or GPU temps when you blow or suck the "hot" air from the rad into the case? This would have been interesting too btw.

With the GPU not providing any thermal output into the case (GPU is idling and has a rear exhaust cooler), the difference might be negible. But what about a top-blower cooler installed on a hot GPU (R9 390X, Fury, Titan X, 980Ti) running at 100%. There should in theory be a noticeable difference in cooling performance between push and pull configurations of the radiator mounted fans.

Could you test using high pressure fans on a rad vs standard fans. Curious to see just how much of a difference it will make.

This happens to be the exact cooler, and fans I am using on the radiator (yeah I know its not a huge coincidence, their both very popular). Informative video! Awesome as always.

almost certain we did this along time ago.

4:14 Pants. Unmistakable pants.

At 1:20 I love the hand gesture Luke uses for "up". Giggity.

Thanks for the info. Was worried I needed a new case for my new GPU, but just realized my PC has the radiator and two fans attached to the front fans. Now I can move the fans or the radiator w/fans to the top to make room without worry.

Damn, some people whine on here like it's their job or something.

why not review multiple z170 boards? or give a lga 1151 build, new content has been pretty shit

I did the same test here and i got the same results... another important thing here is about positive or negative pressure inside the case. Most people just put alot o fans (top/rear/front/bottom) but don't been attention i getting a grat air flow inside. Keep this on your mind!

I'd like to see more tests involving different radiators. I think the quadfans would see a huge improvement over dual fans if you used a thicker, very high FPI rad.

You have already answered this linus.

what about no fan at all with only radiator?

How about radiator placement? When the CPU and GPU is under heavy load, the overall temperature in the case rises right? Does the placement of the radiator make a difference (e.g. radiator in front as intake with exhaust fans at the top or radiator as exhaust at the top and intake fans in front)?

Love this but this really really depends on the fans and on the rads as well. I have my front set in pull exhausting out of the case, i have my side 360 pushing case air thru the rad with 3 fans pulling air out so both are exhausting out. My case has filters all over so no dust worries, will be adding 2 more NF14s up top as intakes.

Idea for new series on the workshop: how to mod [insert component here]!! It would be soo sweet!

If LTT Keeps up this filler......even Naruto will be jealous.

From what I know a fan on top must pull air out the front pulls air in and back pulls air out as well. So the fan is best for liquid cooling in the front of the pc right? Since liquid cooling is meant to pull in cool air not warm air out

4:14 "and we have the PANTS pushing up through the rad..." Didn't know pants were that powerful, to create airflow! ;) haha

YOU SHOULD change the name to "Proving Stuff That Doesn't Matter To Much"

I was more interested in GPU temps with different radiator setups. Like, is GPU temp a lot higher when letting the fans blow into the case (aio as intake fan)?

Love these workshop videos. Suggestion: A video answering the question, does it make a perceivable difference? I don't want to see internal temps, benchmark scores or calculated frame rates in the corner of the screen. Take 6 machines of verifying build and cost. Game for 5-10 minutes. Cycle everyone around the room. Have them score/rank the machines. Can you/they tell the difference?

Really interesting video! I would love to see like a best/worst/average case result compared with high vs. low ambient temperature to folks in hotter or colder countries or people that live in places with variable seasons.

2 last gen cards in SLI or Xfire or 1 new gen card for the same price.

you didnt do the front radiator setup...

Very informative and relevant information even 6 years later Thank you sir

Thanks for reviewing the NuForce HEM lineup Linus, I might get the HEM6 now, but will look into some of Shure's stuff and also that Sennheiser you said you were using on the daily.

do a vid comparing pressure optimized fans vs non pressure optimized/cheap fans also so fan size, 120mm vs 140mm

What case was that?

Please do one about how the exhaust or intake radiator fan set up will effect gpu temp or other components. Recently I got a g1 gaming 970 and I have a Gtx h100i as exhausting out the top which in turn is making my CPU a little hotter, as it is pushing hotter air through the radiator. It would be entertaining to see if maybe an intake on the front or top will change the temps.

Hey Luke, would be interesting to see what difference this makes on an air cooled system, not all of us bother with rads and liquid cooling

Linus' videos are so good. Linus'.

0:42 Video starts 0:627 Video ends You missed out on 2 ads and several promotions. Sorry I couldn't save you from the Twitch Promo during the video.

0:59, shall be my welcome screen on log-on, would love that

awnsering real questions they you have and would not or can't try to solve yourself , I like this series. And for those who don't keep watching one will like you

I would have liked to have seen the results for no fans at all.

Click fullscreen and type awesome

I think a video around how much does the speed matter in RAM would be a good idea for a Workshop episode. Not sure if you guys have done this before...

I'd like to see what would happen if you staggered the quad fan set up, so the back set closest to the cpu pulling up and the two closest to the front pushing down. Best way I can explain it.

wow the comments are filled with picky people complaining about this being a useless test, guys these videos are very informative for people learning about computers. Just because you know the results, it doesn't mean everyone else does too, some people are just learning about PCs and would like to know these things.

from personal experience, the last time this actually made a difference for me was when I had no pressure optimized fans and I had them above the rad pushing air into it. I moved the fans to under the rad and it seemed to create more pressure as they became a lot louder and dropped my temps from 70c to about 40c

installing my first Water cooled AIO unit. My Phantom 410 case only allowed me to pull from top. (without doing huge case modding). Thanks for the tips, good video. Dust management etc. I will do my tests on hard video rendering and see what Temps i get. .....

I'd like to see the impact of RPM, can 4 fans run slower (and so quieter) and maintain performance? Also how would a hot graphics card impact the overall case temp? Feels like dumping a lot of heat into the case would be bad without extra exhausts

That strawpoll was confusing

You only benchmarked the CPU, this doesn't account for the GPU heating the internal air. Using warm air from inside the case to cool the CPU will be worse than cool air from the room.

Have you done a review of a case that is wrapped entirely in cooling fans? Imagine the possible air flow combinations for that as a workshop review :)

So what happens if you are planning a watercooled gpu and cpu system with their separate rads, what would be the best positions for your cooler assuming you had 2 120x2 rads to find a place for?

LTT running out of content iideas

LinusRunningOutOfTips

It was good to see that there is that three degree difference though. This test has good control, but I'd imagine you can squeeze another few degrees with that extra three by improving the intake in other parts of the case. All that extra airflow on the radiator exhaust needs something pushing air in as well. At the least you'll be getting positive pressure and not sucking more dust into the case.

I appreciate you trying like every single config possible. So you mentioned the dust situationi (thank you so much; one of my main concerns) but did you say 'no' dust gets on the fans? only on the rad. Thank you LMG for all your work and great vids.

So who is here because their vessel subscription ran out? Xd

could you actually do some reviews for a change? we havent had a proper review since move

Possible questions: 1. could these different configurations have different noise levels ? 2. could these high end fans be too good to make a difference while other fans might not ? 3. Can you do a workshop videos aimed at noise minimizing scenarios in general ?

Im a noob at watercooling, so these may be stupid questions: Push is where the front side of the fan is facing the radiator, and pull is where the backside is facing the radiator, and push/pull is where on one side the front faces the radiator and on the other side the back is facing it, right? Also, I'm looking to get an h80i v2 for my i7 6700k, and will it perform better than my current phanteks ph-tc14pe? Final question: I heard that its not worth it to do a push/pull config on a watercooler like the h80i v2 because it isnt dense/big enough to make a difference worth the money. Is that true? I also heard that h80i v2 comes with 2 fans already so even if its a small difference i can still push/pull.

To be honest, I am not fond of these videos. Between something like Scarpyard Wars or 7 Gamer 1 CPU these Workshop videos have somthing like a filler characteristic to them. I know they take a bit of time to make but most of the questions asked were answered years ago, even by yourself. If you need "fillers" why don't go back to Unboxings or something like the "LED Lighting for Video", or "HOLY SH!t"? I like Luke as much as anyone here but the workshop videos don't do it for me. Just to be clear, it is not Lukes fault, it is just that the Workshop episodes have nothing for Viewers who are following you for years. Love you guys Greetings

"It's not a graphics card - don't know why it has GTX in it." More like "nvidia cards aren't high-end, late 1960's performance cars. Don't know why they have GTX in them."

what about radiator placement? like if its roof mounted or mounted at the front of the case? could this make any difference to the temperature also?

Awesome. I'm installing this exact cooler today :D

vid came out 10 sec ago xD

25% of this video is an ad

how would these configurations affect other components like a graphics card? if you pull air down through the rad, would that increase the ambient temp inside the case, increasing in turn the temp of other components? or would the hot air from the gpu going through the rad be less able to cool?

Just out of curiosity, was the gpu working 70%+ Load? A hot gpu can actually have an impact on cooling performance if configured for exhaust over intake. That said, it shouldn't be more than a few degrees.

Damn i miss luke and old ltt in general, things change but lot of good people left and the videos sort of lost their charm

use the stock corsair fans. they will blow away these f12. see what I did there :)

Would there be a difference in temperature if you're working with a smaller case and a high GPU usage in terms of blowing air into the case through a radiator or out? Or would it be the same result here albeit maybe higher temps on the CPU?

Best ventilation to cool your drives? Like for example intake or our take to cool your drives?

No graphs. What? All verbal opinion, really LMG?

>Opens video >Luke >Closes video

if i do a custom loop and set the radiators as you did do i need another exhaust fan in the case? or is it just fine leaving the radiators just pulling air in? Going to plan a full custom loop including cpu and 1 gpu

I wanna know that should you place the radiator on top or on the side (240mm) when cooling the CPU
