7C (44F) -- Your Coldest Air Temps? - Overclock.net

StarryNite · 03-19-09

Now HD4870 cards can get HOT, but was more than a tad surprised (and amused) yesterday when I got these temps!

7C (44F)

12 degrees above freezing! lol

Had the AC unit on and the fan is at 90%, and the core did shut down to submit and recieve another F@H WU, but the core goes down not even for a minute (too short to cool a 70C hot GPU).

So what's the coldest air cooling temp you can prove with your ATI card?

i think something is off u cant have below ambient temps so unless u had temps in your room lower than 44f this is inaccurate.

That was a glitch. Happens all the time with every temp monitoring software around.

I guess you missed the three other threads on the same topic eh?

You can also see the lowest CPU temps are at 55F, so this isn't a fluke. The temps are for real. The AC unit was running for 7hrs straight.

This morning the room was at 60F with off and on AC, BTW (why I wear a jacket in this room while folding).

stuck sensors... reading idle temp wrong on the video card.

It's impossible to get below ambient temperatures.

StarryNite · 03-19-09

Nope.

1. AC was on for 7hrs straight.
2. Fan is at 90%.
3. Core shutdown to submit the F@H WU.

= GPU 44F and PROC 55F temps

It would be a fluke if only the GPU registered that temp, but not both.

It can't be real unless your room temperature is like -20C.

When your GPU is outputting heat, how can it get colder than the ambient temperature?

This is the same problem my tech relative was going through, guys. He stated the exact same things as you -- quoting the thermaldynamic law even. But it took him only a day to see what I meant (at that time about heat), and he no longer argues the point! lol

It was cold in this room when I got up and came in. Not below zero (that's ice crystal time!), but cold enough that the case felt like ice.
