I just purchased a used ASUS 5870.  The issue i am seeing is that in GPU-Z there are three censors.

GPU Temperature - 81.0 C
GPU Temp. #1 - 81.0 C
GPU Temp. #2 - 102.5 C
GPU Temp. #3 - 86.0 C

I'm running the card at 889 gpu / 375 memory. I'm a little concerned about the 2nd gpu temperature.  Is it a faulty temperature reading or would it be the heatsink coming off?

I'm getting 370Mh/s with this setup.  The fan is on 44%.  I can push the fan to 100% and GPU to 920 and get about 400Mh/s.

I think i need more fans in my system.  I have an old dell.  Right now the side cover is exposed so i'm considering buying extra case fans to increase ventilation.

But that doesn't discount the fact that sensor #2 is almost 20 C higher than the GPU temperature.

Should i be concerned?

No AC.  Window is open,  70 F here.

Don't know why it's going so high.  Will fans bring down temperature?

Here Also 81°C (Sensor 0) Core 800 Mhz, Load 97% , Fan 50%

Might 81°C be a Problem ?   The Temp goes up to 90° when using 900 Mhz at same Fan Speed.

Fan is too loud for > 50% while sitting in front of the machine.


CPU Temperature:    +47.0°C  (high = +60.0°C, crit = +95.0°C)  
MB Temperature:     +58.0°C  (high = +45.0°C, crit = +95.0°C)

It's ghetto, but you can probably get a 20 degree drop on your card by keeping the case open and making a cardboard and duct tape funnel in combination with whatever computer or non-computer fans you have around (I'm using a USB laptop cooler pad on one system).

If your case already has a fan on the side, you can probably build a funnel to meet up exactly where the fan is when the panel is on.

If you don't believe me, google "computer air funnel".
