Fan/Radiator Setup

Hi, I'm new to this forum, so please go easy on me. I've recently got some more fans for my computer due to it overheating, but this problem still resists. here is my current fan setup: (6fans total)

The case is a corsair 330r, and the CPU cooler is a coolermaster seidon 120v.

Could someone please help me find a better fansetup for my system :confused:

Thank You.

Hi and welcome to the forum :). I think you've got the fan setup nearly there although you want to have positive pressure inside the case (Which you seem to know already :)) and generally the roof mounted fans are setup as exhaust.

Try something like this, it will give better airflow through the case and keep temps lower.

Bad idea having the rear fan as an intake. It will pull warm air off the GPU and make the CPU hotter.

OP would be better off both top fans pulling air in, and the AIO exhausting. The rad will get fresh air from the top, and the case will have positive pressure to keep dust down in the case. The front fans as intakes will feed the GPU cool air.
 
I have found that having a rear as an intake as opposed to having 3 or 4 times as many intakes as exhausts is much better on temps as when you have so many intakes it becomes detrimental to air flow through the case.



EDIT: I'll say this now to avoid having a very lengthy thread that basically comes down to the fact that it's your choice as there are multiple different configurations that will be effective.

1) The option that I gave in my previous post.
2) Front 2 as intakes, roof and rear as exhausts (make sure you have adequate filtration).
3) The configuration offered by Kong in his post.

All of these will give roughly the same temperatures with 5C being a very pessimistic estimate for the differences you would observe.

If anyone would like me to make a post on trying out different fan configurations I would be happy to give some insight for people who are confused on this topic.

I think you are right, there are multiple outcomes. I think the OP might just want to experiment. Depending on what his GPU's do, and how well they tolerate case pressure. I nkow for me with my big rad on top, and my Gigabyte Windforce card, I need all the exhaust I can get or my GPU temps go crazy.

I do think one intake and one exhaust is definitely the wrong direction no matter what the OP does.
 
Erhm yeah, I'd either get a magnetic dust filter and use the rear (AIO) as an intake and both top fans as exhaust, or forget about the top fans all together and stick with the 2 front intakes and one rear exhaust.

I think your overheating problem might have another cause, what are the rest of your specs like? What components are overheating and what are the temps like?

Don't use the top fans as intakes, that'd be very counterproductive as warm air rises to the top of your case and the fans would push it back down, rather than exhausting it.
 
Well before we go into overheating, what components are you using? Something sounds broken to me.
 
In my 750D, I have front 2 as intakes (AF140 LED), rear as intake (AF140 LED), the H100i is in push / pull with 2 SP120 LED's and the included fans on top (SP120L) as the amount of air shifted by the SP's are approx the same values when I run them at static RPM (900 RPM I run them at and they are near enough silent and CPU temp when gaming, or being punished goes to approx 75°c max) as it is the RPM that is different between the 2 of them that causes the CFM difference.

***EDIT***

I did have 2 x AF120 LED as bottom fans as intake, but adding those 2 caused the dust to get in to PC through the various vents that aren't filtered. And yes all intake fans are being filtered by Silverstone Magnetic dust filters.

Say what?... Even though you had that filter, it still came dust in?... I mean, obviously it won't stop dust to 100%, but from your post it sounded worse than what I thought lol. And I've gotten that filter as well (not used it yet though as haven't started the swapping of my case yet though.
 
Thanks for the reply guys, helps alot.


Kong, correct me if im wrong, but wouldn't the fans near the radiator pulling out pull the hot air (as hot air goes up) pull some of the heat into the radiator?

Care to explain more? :P What are you pc specs?

Temps reach 40c+ sometimes, idle

heres my specs:

24GB GSkill DDR3 1333Mhz Ram
AMD-FX 8350 @4.0GHz
Gigabyte GTX 780 WINDFORCE 3X 3GB
Coolermaster 700w 80+ Gold
Windows 7 Ultimate

Windows 7 Ultimate

On the CPU or GPU?

Do you use the stock cooler on your CPU? What software do you use to monitor your temps? Cause with an AMD CPU you should be using AMD overdrive, as other software doesn't seem to get it right.

Wait, so under load it hits 40c? What program do you use to measure temperatures. My ol' amd 8320's (running at stock 8350 clocks basically with a seidon 120M) load temperatures was around 45-50c. 55c is kinda where the cpu might start to throttle dependent on a few aspects.

AMD don't measure temperatures the usual way. The best program to measure it is with AMD's own program, called overdrive.

Im using a single radiator cooling kit, the cpu is getting hot. the gpu is fine, and yeah im using overdrive. im just seeing what would be the best fan placement to get better temps

load its more like 45+ idle its like 40.

Oh right yeah, that's what this thread was pretty much about I'm sorry... :p

40 is a bit high for an idling CPU yeah, how have you got it all plugged in? Are you sure that the pump on your AIO is running at full speed?

(PS: My Xeon 1230 V3 idles at 30-35 C with an H60 2013 Edition, but it's dead quiet cause the fan is set to a silent profile. I've not seen it go over 65 under full load.

Ive got two fans in push/pull on the radiator, top two pulling air out and the front two pushing air in

This was 5 mins ago, just browsing the web; http://i.imgur.com/8LILR72.png
fans are also on full speed

Sorry about that :p
 
Have you checked your mount, ie. have you tried taking your cooler off the cpu and then reapplying it with new thermal paste etc?
