Absurdly high Intel i5 temperature?

Agustin Lanus · Jul 12, 2015

Yesterday my cooler began to make an extremely loud noise, so when I ran a temperature meter software I saw that my CPU temperature was getting up to 128 degrees C.

Now that I've removed a massive amount of dust from my cooler it's not making noise anymore, but the temp program still has the same numbers.

What does that mean? I believe I can't possibly reach that temperature without my PC turning off, so the program must be wrong, but I'd like to know for sure.

I'ts also iterating from like 70° to 128° way too fast, like in 5 seconds, that also doesn't make too much sense

Yes, that is definitely ridiculously high. Try running different programs like CoreTemp, RealTemp, Speccy and Intel XTU to see if they all give the same temperatures. If they read something more normal between 40 and 70 degrees depending on the load, you're good to go. If you are in fact running that hot, replace your heat sink IMMEDIATELY. It is probably defective.

that cant be right, that temperature is far past the heat limiter. im going to go out on a limb and say either the software or the sensor are faulty.

neon is right. Your CPU would be cooked right now, most likely beyond operation. What are you using to measure temps?

It seems it was the program lying

But now I have another question, how can I make my fans less noisy? they are back to full speed and I don't feel like that's neccesary with these temperatures, but I don't want to manually make them go slower.

Yeah. Speedfan is garbage now.

If your fans are connected to the motherboard, you can change them in the BIOS to a lower speed and depending on the BIOS, can have a speed/temp curve. If they aren't connected to the motherboard and just straight to power, there's nothing you can do but buy a fan controller.

Try making your ambient room temperature a bit cooler if you can tolerate it. That way you can lower your fan speed a bit in the BIOS or with a 3rd party program, but you'll keep those CPU temps right where they are.

Okay, several things happened:

After some time having around 40° while doing nothing or up to 70° while doing some really CPU intensive stuff my PC decided to turn off and I couldn't turn it on again until I changed the power supply.

The problem now is that the temps are insane again, an average of 50-60 and up to 100 with just a stream in HD playing.
All the coolers seem to be working properly but once again I don't think I can believe what these programs are saying (CoreTemp, SpeedFan still at 130°)
I can't possibly reduce my room temperature, but I don't think that's the problem

I think the thermal sensor on your CPU might be busted... But just to be sure, does your computer feel unusually hot if you run it with the side panel off?

Not at all, it's not even mild close to the cpu fan.
Is there any way to check if my thermal sensors are working properly?

lindsay24 · Jul 14, 2015

Try some of the other programs I mentioned earlier just to be sure they all get ridiculous readings, but I think the fact that it is reading 128 degrees without melting is proof enough.

Same as with core temp, permanent 100° while stress testing

Oh! I just noticed now that you have an i3-2120. Haha! I have the exact same CPU and I have never once seen it go higher than 45 degrees under load, and this is with the stock cooler. So yeah, I think it's safe to say your thermal sensor is faulty.

Scroll down to "Package Specifications" and look at the Tcase value. That is the maximum tolerated temperature that your processor will handle, and given that it is SIGNIFICANTLY lower than yours, your processor should have blown out long ago. And since it hasn't, yes, I'm saying it's the sensor that's blown.

That's really good news!

Thanks for all the help.

So, is there anything I can do with my coolers being too loud? I'm pretty sure they are trying to cool down 100° with their speed

You should be able to just lower the RPM in the BIOS or with a 3rd party program. Or, you could always upgrade to a quieter heat sink so you don't mind it running at 100% and you get the bonus of extra cooling. Up to you.
