CPU and GPU temperature suddenly reporting as much lower

post #1 of 5
Thread Starter 
My 6600k @4.5 ghz usually idles around 35-40C (with power saving features) and my 970 usually around 45C. However, now it is saying it is idling at 28C (with power saving features) and 35C (without power saving features) and my GPU is idling around 30-35C.

All I have done is take a HDD out to copy some data to another computer and then put it back in.

I first noticed it on Argus Monitor, but RealTemp is reporting the exact same cpu temperature. I also checked the BIOS, and it is reporting 32-34C on stock. If turn off power saving options and put it back at 3.5 ghz (which is what it runs at in BIOS) then RealTemp and Argus report 32-34C, which is in line with the BIOS.

I don't think the applications are reading anything wrong. Is it possible that the temperatures actually dropped by that much just randomly? Or do you think my motherboard or CPU/GPU sensors somehow got damaged?

This just seems very strange.

I don't know, but when you took the hard drive out, did you shut down and then turn off the PSU?

 

Did you reconnect it with the computer off and the PSU off?

I shut the computer down but I didn't unplug it. I've done it several times before that way without issue though.

Edit: It also seems like my temperatures are back up to normal after about 45 minutes. Now getting 35-40C again. Maybe it just had to warm up? I've never seen it idle that low on start up before though.

Yeah, I admit that I was kinda taking a blind shot.

 

Maybe this is normal. I admit that I wouldn't know yet because I don't know much about Skylake, except that it's called Skylake. :)

Maybe. But normally when I start it up temperatures settle at 25-40C in a few minutes. Just seemed weird to have it idling at nearly room temperature for like 45 minutes. I even ran OCCT CPU stress test and Valley Benchmark to throw some heat in the case but the CPU and GPU went right back to where they were. Only thing I can think of is that when I took the HDD out, I left my case door open. Maybe that allowed more cool air in while it was turned off than normally gets in while the computer is off. That then took longer to warm up inside the case, thus leading to lower temperatures until all the air in the case had warmed up. It is probably also worth mentioning that my case fans do not run at all while idling and only briefly while doing light tasks such as youtube or web browsing. Manually ramping the case fans to 100% during idle doesn't really seem to affect temperatures though, so I'm not sure if that really explains the temperature either.
