Solved Is Is Posible To Get A Graphics Card Lower Than Ambient Temperature

[YTBOY83]

My mate was saying that it is not possible that my Graphics card can get lower than the Ambient Temp in my case. Is it possible with good enough cooling that you can cool get your GPU to sit at Temps lower than youe System Case Ambient Temp.??

Not a chance without water cooling or some mad scientist type methods. All air cooled GPU's draw there air from the case. If you could route plumbing to bring in air from outside solely for the gpu it could bring temp's down but I don't believe you will ever be lower than case temp out the back of the GPU.

This is my sysytems temps running idle, i have noticed that none run under the system temp.

Should my GPu be sitting at such a low temp, my mate thinks my GPU sensor is wrong.

GTX 460?? At 68 F has it got power?

Either all the temp sensors are borked, or you're sitting there wearing a heavy sweater with a window open.

If it helps any most of the reviews for the GTX 460 had the temps ranging from the mid 30's to mid 40's at idle. Bear in mind some of those reviews, the testing was done out of a case.

 

[linnemeyerhere]

My GTX 260 OC hovers around 112 F and when working hard can climb to 125 F+

I think all my sensors are fine, its because it is really cold through here and the fan set up i have is quite good.

Yes it is 100% possible to get temperatures below ambient.
No, you cannot do this with air or water cooling.

You need to use phase change cooling (refrigeration) or something like dry ice cooling.

This...lol. Your temps are fine...actually they are amazing for the GPU and CPU.

Well my Pc has 9 fans in total and a damn good cpu cooler, my GTX 460 has a nice and decent size fan as well. Some modifications have helped keep my heat down. It also helps when you live in a cold country lol.

Mine this morning.
HAF 932 Case. 3-220mm fans
1290 Rpm GPU fan.
It idled at 30-31*C all summer.

Check the CPU!!! Scythe Mugen-2 does its job also.
Proof of time is the post 14 minutes ago by RMW020.

I also don't believe it's the sensors. CPUID gave me wrong readings on several different rigs I tested it on
BTW my THRM right now is -271C which equals -457F !!!
So I would suggest to cross check with a somewhat more reliable program like FurMark
FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net
or Rivatuner
RivaTuner v2.24c download from Guru3D.com
or even Speedfan seems to be a bit more reliable.
SpeedFan Download - Softpedia

It always matters, which specific sensors a program tries to access and what (if any) method they employ to prepare the data for output. So if you get an offset (say your real temp would be 20 C higher than what CPUID tells you you could still use it to monitor you just add the offset to know what would be the real temp.

Close enough for me. 21*C on both.

 

[YTBOY83]

Look at the apps running and also my 2 W7 gadgets.

Must be working fine. Thats my conclusion, never run below SYS TEMP.

 

[linnemeyerhere]

It's like perpetual motion you may get close but never achieve it. Any electronic device unless it's a peltier cooler will operate at a higher than ambient temp when voltage is applied. The net rise may be low but measurable. In a GPU as much energy as it draws IMO there's not a snowballs chance in Hell that it can operate at or lower than ambient temp. But sensors and measuring techniques are so variable that one needs highly calibrated instruments to know for sure which none of us have to be 100% accurate.......nor is this needed as getting close is all we really need to be safe.

One thing that no one has mentioned that is asking/showing these low temps, what is the room temperature the computer is in?

And linnemeyerhere, well said.

Yes.............do this to your gpu core

What stood out to me was the readings on the +12v.
Is that correct?

Love it!
Kinda hard to get any work done though.......

If you're referring to the 6.38V in rmw020's screen shot, missing or mis-calibrated sensor. The computer wouldn't even turn on if it was correct.
