Question

Computer temperatures

Sep 9, 2015 6:31AM PDT

So I have been checking my temps lately on open hardwaremonitor and it is giving me 3 temps. Temperature 1 is my cpu which runs at 32c on idle and roughly 45 underload. Temperature 3 is system temps which is about 25 on idle and 32 under load. Temperature 2 is the unknown temp. It os about the same as the cpu socket at idle but underload on prime 95 it can and usually does shoot up to 70c. Then once I turn off prime 95, it comes back down to idle temps which suggest this may be a real temp. I have no earthly idea what this temp is. Can someone please help???

My system:
Cpu: fx 8320
Cpu cooler: cooler master hyper evo 212
Gpu: evga gtx 970 X2 sli
Mobo: msi 970a g46
Psu: evga 750w 80 plus gold
Ram: 16 gb patriot viper ram
Hdd: WD 1tb 7200rpm

If that open hardware monitor is buggy

It's back to them to answer why and if it can be fixed.

As to why a CPU shoots up in temperature under load, that's what CPUs today do. And why it doesn't come back to the first temp is physics. It will take a long time to get back to the first temp.

Yeah I get that

I'm just worried about that 70c temperature. I don't get what it could be

It's because when the CPU works, the temp goes up.

That's how it has been since the first CPUs. There are folk that worry about it and what to do about it is nothing. Unless it's out or over the spec then what's the issue?

PS. That would be a question for the PC's maker.

While it's a mystery what it is, there are temp sensors all around the PC such as the HDD and that is rarely in the BIOS since it could be non-standard.

the highest temperature is the CPU

no matter what the temp program is claiming.

I don't think so

My bios shows that temperature 1 is 32c to 45c is my socket. I understand that there are core temps as well and the don't get past 36c and it is common for the socket to be 10 degrees hotter. The temp in question is that one that gets up to 70c which I can't find in bios or control center or anywhere

the only two items
Sep 9, 2015 7:28AM PDT

that can run the temp up that high and not have almost complete failure are the CPU and GPU. The CPU temp will head up first, before the GPU, although the GPU temp on a really "hot" card can then exceed the CPU. Look in the program settings, may even have where you can reassign the temp measured to a part. If so, then it's the CPU.

Then why
Sep 9, 2015 7:36AM PDT

Is my bios and control center bothe confirming that temp 1 is my socket. Bc when open hardwaremonitor says my socket is 45c my control center also says 45c. When I boot into bios it naturally drops a few temps to around 35 or 36. Then goes down to idle temps from there. If it were 70c then by the time my system boots into bios it my drop to 50 buts cetainly not 35 or 36

Keep in mind

Folk have been reporting disparity in the readings on temp monitors for years. Your question should be to that App's author.

However, a BIOS barely taps the CPU and other things so it's the lowest possible use. Once Windows is running you should not see the BIOS temps again. This seems to confuse those new to this area.
