Best software for constant GPU and CPU temperature

post #1 of 8
Thread Starter 
Hi all,

Thank you for reading and thanks ahead of time for any suggestions you have to offer.

I am looking for software, or multiple softwares, which when run will produce a consistent temperature from the CPU and/or GPU, so that I can accurately determine the effects fan speed and configuration has on temperature.

Does anything like this exist? Most benchmarking software seems to take the system through various scenes, changing the CPU/GPU demand and varying the temperature.

Thank you again!

You should check out NZXT's CAM 3.0. MaxPC just recently reviewed it: http://www.maximumpc.com/nzxt-cam-30-review/

Thanks, clawlan. CAM sounds nice but I'm not looking for software to compare my results with others, I'm looking for a proven consistent temperature software. The article you attached literally doesn't mention a thing about that. Still, great looking tool!

Cam software has gotten a lot better. It's not really designed to compare results, it's actually exactly what you requested. I noticed that it wasn't loading correctly on my system when I had " Start minimized" under settings. Uncheck that if you have startup issues, also uncheck "FPS" if you have OSD monitoring software already.

Thank you all for your suggestions. After some research, it looks like this product doesn't exist. It's not possible to maintain a constant CPU/GPU temperature.

Well, any of the mentioned oproducts (CAM, SpeedFan, etc) can just leave running in the background and it will give you what you want. You can also look at Rainmeter and SysTrayMeter,

I think I poorly worded the question and explanation. I was looking for a software that would produce a constant temperature, i.e. it would always remain at 60C, so that I could vary the fan speed to determine an air saturation point.

But this product doesn't exist because it's technically complicated. I see that now.

"Constant" temperature isn't practical, nor necessary in the marketplace. That's probably why you haven't found something that suits your particular desire. There are many programs out there that will increase fan speed, etc. to keep MAXIMUM temperatures under control, e.g. SpeedFan, Afterburner, PrecisionX, etc. As for MINIMUM temperatures, those aren't usually elevated artificially.

In the industrial world, temperatures can be kept constant using a feedback loop and a suitable Peltier / thermoelectric cooling device. As temperature goes up, current to the TEC goes up correspondingly to keep the temperature under control. I've seen precision controls for laser diodes keep a diode within +/- 0.1 C, and similar systems exist for TCXO (temperature controller crystal oscillators) for professional radio transmitter/receiver applications where frequencies need to be EXACT.
