Case air circualtion causing high temps!

post #1 of 17
Thread Starter 
Well after ocncluding that its not my MOBO, CPU or GFX thats causeing the problem its evident that its my CM690 that is having the high heat problem.

My cpu and gpu are having EXTREMELY HIGH temps. GPU is around 60 on idle with a HR GT thermaltake cooler and my cpu is around 48 on high speed on my yate loons and 55ish on low speed while orthos tested. Its around 46 and 48 on idle. Basicly if my loons are on high the CPU temp is similar around 46-47... But if low the increase very high.

I'm afraid to OC the CPU as 46 on idle is high (i think at least) especially with WCing.

Its evident that its the case as the gpu used to be around 30 in my previous AEROCOOL 3T Extreme case while the GPU was OCed... It is stock in new case!

My current fan configartion is 2 top fans assosicated with the rad push air into the case (if they pull it out the temps of the cpu are above 50 all around). I have the two side fans , pushing air in. The front on is pushing air in. So its 3 in 2 out

The air in the case must be very hot. The out take fan if you put ur hand infront is burning hot.

I need to know HOW to elliminate all this excess hot air from the case Or is the better solution to change case? (even though i only got this case recently)

P.S The case is also hot to the touch :/

try changing your fan configuration to have more exhaust fans than intake fans. I found this helped me.

Also, what's your cable management like? All these fans are useless unless you have a space for it to flow through. If it's bad then it is worth the effort to tidy it up a bit.

I don't think a new case is necessary at the moment, i have heard good things about the cm690. They even have their own fan club on here. Link

whoah dude, thats not normal. i'm a little confused as to how you have your fans configured? as I understand, you have two top fans on your rad pushing in, one front fan pushing in, two side fans pushing in, and an exhaust in the back? if so, you have a case of excessive positive pressure, which causes exactly the situation you are experiencing, which is hot air cannot escape as the intake is higher than exhaust. in my opinion, negative airflow works better, having more exhaust than intake. i'm not sure why having the top fans as exhaust causes your temps to go even further up?

so you have 2x120mm fans pushing air through your rad into your case?

if so then maybe it's time to start thinking about mounting it outside the case.

Try making the side fans as exhaust. With the rad fans pushing in and then the side fans pushing in it seems like you're just making a stagnant pool of hot air from the rad in the middle of the case.

Actually it was 2x from rad pushing in + front pushing and a side...

I know how both side fans as exhaust so i have 3 in and 2 out

The rad fans pushing air in rather than out actually helpd decrease temps. When i had them pulling air out of the case my cpu fan was idling at 50 on high speed. They idle 44 on high now and 49 on low.... Still not what i really want for stock temps :/

In regards to cable management there is almost no wires in the front of the case only behind the tray so air circulation around the mobo is pretyt clear.

Can you grab a pic of the case for us? That would help some. Did changing the side fans help any?

Well changing both side fans to out seemed to work im now at 43-44 idle on the CPU and under orthos load it goes to around 47-48. The good news is that under any windowed game temps don't rise that high. But still this is Stock

The gpu is still burning like mad 60 idle 80 non idle, and its probably due to not having a fan on it :/

In regards to a pic about the inside of my pc :



Its not the best cable management but at least the mobo area is clear!

I agree with everyone up there. and if all else fails, get stronger fans. Also get better cooling on each component. Get that video card a fan and get the CPU a better fan. Personally in my case, I have two fans in the front and one fan on the side intake, and two fans on the back and one fan on the top exhaust.
