Windows 7: Temperatures

Temperatures

Hi all,

Just wondering: what is considered a "high" temperature for a CPU and GPU? I downloaded a program called SpeedFan which tells me the temperature of my processor and GPU. It tells me the temperature of each core and 3 of them are about 28-35 degrees while idle, but core two says -128 degrees. I don't understand why, could that be an error or does it mean something?

Also, is 60 degrees a little hot for my GPU while idling? SpeedFan displays icons next to the temperature: blue arrow means cool, red arrow means heating up, and fire means hot. My GPU displays the fire icon. I think I'm going to have to add in another fan or two.


Thanks,

George.

Hello,

Those temperatures seem very normal. A high temperature for a CPU is 70C. nVidia GPUs can safely get up to 100C, but I believe in reality, they could go hotter.

60 for your GPU is actually quite cool.

I can't say I understand why one core is reported at -128. Try another program, such as Real Temp - CPU temperature monitoring

I have always used Speedfan, so I can't actually recommend another specific program.

When SpeedFan can't read the data of a given value, it will usually give a value such as your's does. I wouldn't get concerned about it, except in terms of other possibilities. Sometimes it isn't going to read a value properly, regardless of what you may try. In that case, if you want to continue using SF, I would simply disable that reading in the configuration. It is possible that the reason for this is due to the chipset driver not being installed properly, or possibly due to the AMD Optimizer or some other aspect of AMD software malfunctioning.

The only way that I can see to pursue this, is to open the Resource Monitor in the Task Manager and see that it has 4 windows displaying the cores and that all four cores are sharing the workload. If this appears good, then I would revert back to my previous paragraph.

I'm not familiar with your GPU but my GTX 260 idles at 47c at 50% fan speed.
If I thrash it in a game I turn the fan up to 75% and after an hours play it's around 60c to 70c.
I use EVGA Precision to monitor my GPU and there's also Riva Tuner. Both are really easy to use as monitoring tools and you can also use them to overclock the chip ( I don't) and control fanspeed.
They're both free but if you want the EVGA Precision (which I really like) you can't get it off their site unless you have an EVGA card. I just download it from filehippo or guru3d.
Check out the list of free software in the software section. Hope this helps, J

My 4890 can hit 70 degrees celsius or less under load if I play for 5hrs with minimal breaks. As for the CPU, 50 degrees with a stock heatsink at load is normal. Your temps are fine.

Try HWInfo32 for another look at it. The link is in the drivers guide in my sig.

Hi guys,

Thanks. I wasn't worried about my CPU temps because they appear fine. Task Manager shows 4 windows with each core working so I'm not worried or anything, just wondered why it shows -128 .

Also, Jonathan: I tried that program but it only works with Intel processors .

Anyway, I wasn't actually concerned about the processors temps I was just a little curious about what's considered hot, high and over heating. 60 degrees seems to be fine, it's come down a little now. I opened up the case and directed two fans directly at it and it cooled to 46 degrees, so I'm going to add those in properly tomorrow (bodged, of course... gotta drill some holes in the case ).


Thanks.

I wouldn't bother - buy an Antec Two Hundred - cheap, plenty of airflow, comes with 2 fans (top, back) preinstalled with space for another 3. Hopefully you have the right molex connectors on that PSU to install the fans.

Since nobody seemed to have asked... what's your CPU/GPU? Every company has their own specs for operating temps..

While you're definitely still within an acceptable range, it's still good to know what's expected.

I know my 8800 GTS is rated at 105 C. So my 60C idle is pretty good.

I use a program called Everest to monitor my temps/hardware.
