High temps in CFX

post #1 of 4
Thread Starter 
Hello all.
I dropped another 5770 in my rig a while back, and never really looked into my temps until recently. I added an ASUS CuCore to a setup that already had an HIS IceQ5 in the upper slot. I have my soundcard wedged between them, but the HIS still seems to have plenty of space for air intake.
Anyway, during Crysis 2/BC2/most games, my HIS is running up to 20C higher than the ASUS below it. I know that somewhat higher temps are expected, but this seems a bit high.
The ASUS tops out around 65C or so, while the HIS is often around 85C+. I have near overkill airflow, and neither card is OC'd. (mostly because I haven't been able to flash the HIS to an ASUS bios.)
Anyway, all the info I have points to the stock voltage of the 5770's as being 1.125V, and the ASUS was clocked at 1.25 when I first installed it. At that point it was the hotter of the 2 cards. The HIS is running at 1.2V according to GPUZ, and I used Afterburner to down the voltage on the ASUS back to what is supposedly stock settings.
Any ideas or suggestions as to how I can get my cards voltage down? Or should I be trying at all?
I also tried to OC the HIS before I ever added the 2nd card, and it wouldn't stay stable at even 950Mhz, so I think the high voltage might have something to do with that as well...

The top card will always run hotter however I would maybe try to remount he cooler and check the paste if you haven't/have just to be sure its not causing the issue. Voltage is the main reason for higher temps and since you have great airflow in the case I do not think that's anything to worry about. Lower your clocks would be only way to lower volts if its as low as it can go stable at those clocks. The temps aren't really too high they can go up to 90-100c iirc, you are close but if it never gets any higher then that then I think you should be OK. Anyone else have any info to drop in this thread to help out?

Already removed cooler, cleaned completely, and reapplied Shin Etsu.
No difference in temps.
I'm just wondering why the stock voltage on the HIS seems so much higher than it should be.

Small bump, and wondering if anyone has flashes HIS bios before, and how they got it to work. Same question applied to the Sapphire Trixx software as well.
