I seem to be having some cooling issues with my hydro h50 cooler and wondering if there is a problem. I put this build together a few weeks ago and have been tweaking things here and there and finally got around to the overclocking. I've gotten my cpu up to 4ghz stable although the temperatures aren't really where they should be for this type of cooler.
My idle temps with ~1.18V on an i7 930 @ stock are at about ~44C.
My idle temps with ~1.25V on an i7 930 @ 4ghz are at about ~49-50C.
My load temps with ~1.18V - 1.2V on an i7 930 @ stock are at about ~79-82C.
My load temps with ~1.25V-1.26V on an i7 930 @ 4ghz are at about ~85-86C.
The ambient room temperature is about 24C.
I'm currently using a push/pull config with Coolermaster R4 2000rpm / 90CFM fans attached.
Using the fans as an intake config to blow air inside the case on the HAF-X.
Using the fans as an exhaust config to blow air outside the case.
No difference there.
Reapplying the TIM using the small rice grain method to the center of the cpu and then seating the cooler on top using MX-3 TIM. - Didn't help
Reapplying the TIM with a thin layer spread equally to the bottom of the heatsink instead with the cpu cleaned off (i'm using isopropryl alcohol to clean off the cpu and heatsink between every cleaning/application). - Didn't help
For reference, i will also describe the airflow setup inside of the HAF-X.
2x200 or 230mm fans on top of the case : both intakes
1x200mm fan on the side of the case: intake
1x200mm fan on the front of the case: exhaust
Hydro h50 with push/pull config pushing air into the case
(i found this method was actually better because the temperatures werent any different if i used it as an exhaust, although the IOH temperature on the board was much lower when the fans were blowing inwards)
1x120mm fan on the vga airduct addon for the haf-x blowing air to the back of the case underneath the video card.
I've read about many good things about this cooler and have seen people with some phenomenal temperatures.. but I'm just not seeing it here. I've reseated the heatsink like 3-4 times now and reapplied the TIM after cleaning it everytime. I've also checked that the pump is operating at the proper speed and it's being reported at 1419RPM with both of the coolermaster fans at ~1860-1890 RPM.
Any ideas on what the issue might be?
also tried running it with a single intake fan, temps didn't change much at idle, and about 5-7c difference at load temp. also tried reapplying the tim for the 4th time to the cpu, didn't help either. i'm out of ideas and thinking my cooler is faulty.
if i understand this correctly you have your top fans trying to force cool air down through the rising hot air and then attempting to exhauist out the front/bottom of the case? you might see some improvement from using the bottom/front 200mm as intake and exhausting out the top and top/rear as this is more in line with how the air wants to move.
Also, how do you have the push/pull and pump connected? If you currently have them on headers maybe try using the molex adapters to ensure they're running at max for now.Edited by slimbrady - 7/31/10 at 7:39pm
