CPU running at 94 deg Celsius!!

Hi folks,
I got a bit of a shock when I just opened Speccy to see how my graphics cards were going, because they (2x) generally run on the "warm" side (one at around 60C and the other around 80C) ... which, even though this PC was built "professionally" and has quite a number of fans ... is quite warm.

But the shock came when I saw that my CPU was running at 94 deg C!! At the moment, the current reading is ... 91, but it's fluctuated as "low" as 84 C a few minutes ago. It's never run THIS hot before, a bit over the max of 68C but this is now serious!

What's the best way to get the temp down in the future? Right now, I'm gonna turn the thing OFF, until there's been time for some replies from you good people.

BTW, this computer is NOT overclocked!

Having "quite a number of fans" isn't necessarily a good thing, especially if they're not configured correctly. I highly doubt your CPU temp is 94C though - try another temp monitoring program or check the temp reading in the BIOS.

As above, confirm core temperatures in CPU, I use SpeedFan, but as pointed out, checking in BIOS may be best. If your temps were that high, the CPU fan would be screaming until the board would shut the system down. About the only way your CPU should climb very high without overclocking and stress testing, would be if your CPU's heat sink has come unmounted or they left off the thermal compound when attaching it. If you confirm that the temps are anything over 40 at idle or over 60 under load, check or better, remove and reset the heat sink with a quality thermal compound. See: http://www.arcticsilver.com/methods...
As far as fans, you should have flow through your case rather than just many fans interfering with each other. You should have a front fan down low blowing into your case and a rear fan high in the back blowing out (exhaust) of your case to keep colder air flowing in, up, and out as warmer air.

You have to be a little bit crazy to keep you from going insane.

Thanks for your answers people. Well, since yesterday, the temps have been running a bit cooler, ranging from 84C down to currently ... 72C. In desperation, until I've worked out a better cooling system, I've pointed a large fan at the side of the computer. It's about 7 feet away, yet has still cooled the thing down. That 72 reading was from Speccy. SpeedFan confirms this, with the core temps varying from 71 to 73.

I've previously purchased and laid down some heat sink silver compound (I need to find it again to put more on, eh?!!) ... but I think the bigger answer is to organise those fans.

Thanks for your assistance!

Finally, from http://www.computerhope.com/issues/... it says that the CPU shouldn't run higher than 95C. Now, that's just below the temperature at which water boils ... and even my old AMD has a water cooling system built into the mobo, but I think I'll go air cooled. Just something about H2O and electricity of ANY voltage and amperage linked to mains power ... just a personal thang! (We have 240V here Down Under, and lemme tell ya, 10 amps does just a little more than tickle ya.)

Did you try another hardware monitoring program or check the temp reading in the BIOS? 95C is ridiculously hot. The system should be shutting down or at the very least, throttling, in an attempt to lower the CPU temp. Try using HWMonitor & see what you get:


As for the cooling fans, you didn't bother to list the configiuration so we have no idea what's going on. All that's generally needed is ONE exhaust fan in the rear of the case. Side panel fans are disruptive & front intake fans are of little benefit. Obviously some of the individual components have fans of their own (CPU, GPU, PSU). Speaking of the PSU, cases that have the power supply mounted on the bottom have poor cooling characteristics. It's much better to have a case with a top mounted PSU.

When applying thermal paste, it's extremely important that you do it correctly. If you use too much, the paste acts as an insulator & blocks the heat transfer to the heatsink, thus causing the CPU to run hot. The Core i7 uses the "vertical line" method:

Hi Mickliq,

Sorry for not replying earlier ... but at the moment, I'm still looking for the key that unlocks the case! Until I've found that, I won't be able to give you the fan configuration. When I had the system built, the guy placed a fan on the side, blowing over one of the video cards. The case comes with 2 exhaust fans and 1 at the front, that much I know and can remember.

However, I HAVE used HWMonitor, thanks for the link, it reads 72C right now, while Speccy reads 77C and SpeedFan averages the cores at 76C.

As for using the paste, I was careful about applying it, but I'll take a look at it when I get the case open, as the video cards also run hot.

Addendum: re-reading the HWMonitor graph ... In the first place, I should've read the LEFT column, the value one, which reads 61C, which is far better than reading the MAX value, which WAS 72, but for some reason, now reads 62!

Anyway, the CPU is now substantially lower than the initial reading of 94C that Speccy gave me. Again, I'll get back to you once I've managed to open the case and will check up the BIOS temp then too.

Cases with locks are usually server cases. If this is a computer in your home and you are not really worried about someone messing around inside, then skip the lock if you can use a screw or thumb screw to hold it closed.
Since this computer runs this hot, and you did not build it, you cannot rule out that the CPU or the GPU(s) are not overclocked unless you investigate. Use CPU-Z to read CPU specs and note them at idle and under stress. Also note the Vcore voltages that they are running under in SpeedFan and in your BIOS since this is where most of the heat comes from during overclocking. and look for graphics overclocking software, usually titled 'Performance....' and see what you can find out there.
