What kind of setup would you recommend ?
120 rads are usually put as rear exhaust. You want the heat to go out.

Thank you for your input.
edit : I know about that, I currently have 2 exhausts already, one at the rear and one on the top. I'm just wondering how I can change my current installation when I'll include the new radiator.
Towards the ouside it is, then, but push ? pull ? Push/pull ?

If you have a spare fan push/pull is the best, but you need to have screws long enough to hold the extra fan. The most common setup is on the rear of the case but you can put it on the top if you have the space.

Thanks a lot. I do have a spare fan and the watercooling unit comes with long screws.

bump. I would appreciate additional help on the matter even if Agaster somewhat confirmed my primary push/pull (towards the outside) idea.

Have a bump because I'm too clueless about watercooling to help. You know where you should ask tho, right?

Yes, I know, I was just being lazy... And sometimes browsing CPC can be tedious - I mean the ergonomy annoys me - and I find myself better as a lurker there, while SG is my second home. I just wanted quick feedback on the matter :-)

I totally know what you mean, don't worry :3 I'm sure you'll find good help here too.

Which CPU, and how does the rest of the case look like?
Comment has been collapsed.
The CPU is a i7-4790K, the case is a Cooler Master CM 690 II. The airflow is quite good right now, only the CPU gets hot - certainly due to its stock cooler.
Air is pulled from the front and pushed via rear and top. I plan on putting the radiator on the rear but I'm still hesitating about mounting one ventilator on it (push, towards the rear) or two (push/pull, towards the rear). Right now it seems push/pull towards the rear is better but since some people seem to disagree and voted pull only, I wonder what the arguments in favor of this option are.
Comment has been collapsed.
Rear exhaust with push / pull.
But btw.: a single rad for a 4790k?
No offense, but that's a rather bad decision. I'd go for something like a nh-d14, dark rock, or evo - same price, and better performance.
Comment has been collapsed.
No offence taken :-D
I happened to stumble on a coupon that let me have that specific model almost half-price (28€ instead of 55€) so that's why I went with this one. Oh well, I might consider to upgrade to a double later in the future. I would gladly have bought a better one but finances don't allow me.

Well, for 28€ it "gets the job done".
You got a rather large chassis, think about a decent air cooler instead of going dual rad AIOs - most AIOs are not worth the money IMHO, except you lack space.
Comment has been collapsed.
What I'd recommend...redeem the coupon and sell the seidon. Get an Air cooler, it will be the best thing for the 4790K until you decide to get a proper water cooling system. IMO closed loop water cooling is bad in terms of performance when compared to Air Coolers. Closed Loop systems are also a deadend and gets ineffective as you cannot do a proper maintainance. The coolant inside it will be ineffective as time pass by.
Anyway if you still opted to go for a single rad closed loop system.
The best mount is Push/Pull towards outside the case mounted on the rear or on the top.

Thank you. Yes, that seems best, but I'll wait in case some people have a different opinion on that. Look at the votes right now, more in favor of pull than in favor of push/pull. I'm starting to wonder if people really understood the question, hence why I cleaned my OP a bit.

I think the setup really depends on your temps and your case.Try just one fan pulling heat from the cooler and see how the temps are doing,no need for 2 if it keeps it cool enough.I have one fan that pulls heat off the cooler and my temps at idle are around 30c.
Push pull is usually only effective when you have a front case fan most of the other time is just a waste of space and energy as even then most of the time it lowers it only by a degree or two.I say try it with one fan it will not take much to add another and one fan will be plenty to keep the temps from getting to high unless you live in a broiler room.
The biggest thing that will matter is the heat inside the case with mine it sits near the a/c so it does not pump in warm air so i can pull heat away without much issue i could maybe lower it a bit more with push/pull but no need..Though if you do a push/pull just remember it might be doing more harm then good if it just pulling warm air from the case push/pull works better when the air coming in is cooler then the air going out.Push/pull could also make other components hotter if it is pulling warmer air in from say the video card or even taken away air that keeps things cool.I have a fan by my video card that pulls hot air out from it and even at load the air coming out the fan is never warm and board temps stay around 25c
Anyhow what case and what cooler are you using?What are the temps if your board and other components?You can get that info from Speccy if you where not aware.

I hope this helped some i know it was a bit long winded but if you have a good case for cooling and the temps inside the case are decent i think one fan pulling heat from the cooler should be enough if not then you could try push/pull.

Thanks. My case is a Cooler Master CM 690 II. Right now the CPU cooler is just the stock ventirad. When doing nothing special - not sure if that can be considered idle, I'd have to take measure before booting to check for idle temps, right ? - my temps are all around 30-35 degrees. GPU is 35 right now, the CPU moves from 31 to 36. The room temperature is 21 degrees.
When playing... I can't remember the GPU temp right now because these days I had my eyes on the CPU temp, but the GPU kept cold enough. The CPU, on the other hand, was hitting over 85 degrees while playing The Witcher 3.
I don't have the new cooler yet, I just ordered it. It will be a Cooler Master Seidon 120 V VER.2. Its radiator will most likely replace the rear exhaust ventilator. (currently I have a front intake and two exhausts : rear and top. All three of them 120mm fans.)
The overall temp is quite satisfying right now, all I'm concerned about is the CPU.
In any case thank you for your input, I will keep that in mind.

As Evil says a push pull will give you a couple dregree drop but I always go with it. It will help to accumulate more dust in the radiators surface area but to me its worth it, I am a bit of a cooling freak though. Make sure to mount at least one fan ehausting through the top at the rear, I do believe your case supposrts top fans. Using a radiator with push pull will eliminate alot of the airflow from the VRM which gets very warm, you'll want airflow exiting the top to ensure the VRM doesn't heat up too much now that the stock cooling has been replaced. I personally also mount a 120 or 140 in the 5 1/4' bay area to force air towards the ram and Northbridge. Last, I've found that hot gluing a 50 or 60mm slim fan to the backplate on the motherboard blowing on the back of the CPU socket yeilds a 3 to 6 degree drop in CPU temperature.
Make sure to use a high quality thermal grease, just a pea sized amount on the CPU. I highly reccomend Artic MX-4, it does not dry out like normal pastes and does the best job I've seen myself transferring heat from the CPU to the water block. If you really want to go all out, replace the stock thermal compound on your GPU as well, it will benefit from it.

- Yes it does support top fans, and I already have one exhaust there.
- What is VRM D: ? Sorry, engrish isn't my first language
- thanks for the advice about ventilator behind the motherboard, I might consider it in the future
- I happen to have some quality Arctic thermal paste, not sure which one, that I bought when I got the 4790K (replaced the stock thermal paste that I didn't want)
- I'm not yet ready to touch the thermal paste on the GPU, but, yeah, maybe I'll get there someday.
Thanks a lot for your advice !

Well the VRM is the Voltage Regulation Module. As its name implies, it regulates all the voltage on the motherboard. Its a collection of capacitors that is usually found between the CPU socket and the mobo's outputs ( usb, speakers, and such ). Most modern boards have a long heatsink attached to it with double sided theremal tape. A push pull radiator mounted on the rear will cover this area, effectively removing airflow from it.

VRM is on the motherboard and if it gets to warm its not a good thing,it also can tie in with over clocking.
A voltage regulator module (VRM) is an installable module that senses a computer's microprocessor voltage requirements and ensures that the correct voltage is maintained.
As far as the GPU unless it is running hotter then you like or is having issues staying cool i would leave it a lone as it could void the warrenty if you remove stuff unless it is out of warranty.Also its a bit more involved then say then putting paste on the cpu
Looks like headmonkey also replied lol

Idle is just when the pc is running and not doing anything or very little like viewing this site is not going to raise your temps or should not anyhow unless you have a lot bloat.Speccy would show the board temp,the cpu temp,hard drive temp,
That case should be just fine for push/pull if you wish to lower your temps even a bit lower as headmonkey said it will cause a bit more dust build up and such but that is up to you.I just prefer things simple so if i can get away with one fan great.Good thermal paste and using just enough is key to the best cooling as no matter how good the rest is setup if the thermal paste is not up to par it will not cool as good.
My setup is 2500k which i have not over clocked but when i get my new video card i will be,but i have only 3 fans in the whole case and it suits me just fine,one is as i said pulling air out from my gpu on the side panel,the other one is pulling cool air in from the front of the case and the 3rd is pulling heat away from the cooler and my temps are just fine.I wanted to put the rad on top of the case and pull cool air from the back but my mb gets in the way of me mounting it on top due to the heat spreaders on the mb.
Also when you get your cooler you can use..Prime 95 to test your temps and make sure things are stable
http://www.majorgeeks.com/files/details/prime95.html
Either way you will be happy with the water cooling and it will make your system cooler and more quiet and will allow you to over clock if that is something you want to try but in the end i think no matter which way you go push/pull or just one fan you will be happy

The diagram below is pretty much the standard for PC cooling enthusiasts (in standard case design). The important thing is to keep the airflow going in one direction through your case and not build any "hot spots" over/under any high heat components. My radiators are both push - one in the bottom of the case (240mm x 65mm), and one at the top (360mm). With a smaller radiator like the one you've purchased, you'll get more benefit using push/puil, though push will do the job as well. Try both and see which you prefer, imho. More fans mean more noise, and I like everything as silent as possible.

it all depends on the rest of the configuration....
what kind of overall airflow are you running
thanks for the blacklist :D

I have a list of reasons why I blacklist people... I don't maintain it very well. You weren't on it, and by looking at your profile, it's in good standing and I have no idea when and why I decided you were on of the baddies.
In any case, you're now de-blacklisted.

oh hey, nice and thanks a lot. these are the reasons why i whitelist people, i know exactly what you mean by forgetting the reason i blacklisted someone :P

^^ Great video, I'd give that a look. I vote for pulling towards the outside.

They also posted another video a couple months ago that Luke made. The recommendation is the same as the previous video, but they setup a computer with all the different configurations and take temperature readings. Radiator Fan Configuration: Does It Matter?
If you are interested in other cooling related tests, they did:
Cable Management - Does it impact cooling performance? At all?
Case Fans - How many should you have?
Thermal Paste Application Methods - Which one is best?
Does Power Supply Orientation Matter?

Just a last bump for the gibs.
Thank you guys for the help. I guess I'll just go pull towards the outside for cleaning purposes, and maybe, one of these days, switch to push/pull if I feel the need to (I'm not intending to overclock the CPU so I guess I will already have a huge benefit compared to the stock cooler).
I whitelisted some of you who took some time to answer me, hope I can thank you with some whitelist gibs one of these days.

Really the last bump this time, 6 hours left for the giveaways.
Comment has been collapsed.
tl;dr :
I'm getting a watercooling unit for my CPU, and I wonder in what direction I will mount the ventilators on its radiator.
Do you think it's better to just do push, pull, push/pull towards the inside or push/pull towards the outside ?
If you have no idea what push/pull means just pick the lol u noob option and move to the giveaways :-D but if you vote for either option feel free to tell me why you prefer this way.
Thank you !
