Overheating Issue

Bhogal · 7 Apr 2013 at 07:22

My system appears to be overheating and I can't figure out why. Everything is cleaned and clear of dust.

When turned on from cold, Core Temp is showing 90-95, going quickly up to 98 degrees after about 10 minutes low use (i.e. checking e-mails).

Any ideas or help?

I had my system from Overclockers back in October 2011, so not very old:

Coolermaster CM690-II Advanced Case - Black

Intel Core i5-2500K 3.30GHz Quad Core Processor

Stage 4: Overclock of CPU/Memory - 25% Overclock (Processor speed x1.25 / Max Attainable RAM Speed)

OcUK H2Flo Extreme Liquid CPU Cooler

Asus P8Z68-V LX -Intel Z68 (Socket 1155) DDR3 Motherboard

Kingston HyperX Genesis Grey 8GB 1600MHz CAS9 Memory Kit

OcUK GeForce GTX 580 1536MB GDDR5

Crucial RealSSD M4 128GB SATA 6Gb/s Solid State Hard Drive

Seagate Barracude 1TB SATA 6Gb/s HDD

OCZ ZS Series 750W PSU

Sharkoon 120mm 2000RPM Fan

Sounds like the cooler is not seated correctly.

Have you removed the cooler from the CPU, re-applied thermal compound & seated the cooler again?

You say it is cleaned and cleared of dust, have you also check the radiator is not clogged up with dust. Also check that your fan is actually working, may be try another one.

I haven't checked the CPU actually. It had a watercooled system attached to it, which I am not too familiar with. Will investigate further. Its one of those internal watercooled systems, self maintained.

It's a closed loop cooler.

As above, if you remove the fan(s), you can see the state of the rad.

Cheers. Will check. I presume I will still need thermal paste?

Also check if the pump runs.

Ok, how do I do that?

You should feel on top of the pump a small vibration, it might be worth disconnecting hard drives and fans to help with checking.

Ok. Will try that too. Thanks

Had a look at the water cooler and radiator is clear of dust, still running hot. It is attached directly to cpu with thermal paste. It isnt dusty or dirty under there either. Any other ideas?

Pump seems to be working fine too. Just checked that as well.

Where do you have the pump plugged into. You may have it in a PWM header which will only run at 50% unless you set it otherwise.

Not sure, however nothing has changed since 2011 and it has only started overheating now. I don't know which socket is which

As it's an asus motherboard I did have an experience recently where core temp / Hwmonitor were all showing incorrect incredibly high temperatures which did not match what temperatures were show in the bios. I would possibly recommend ASUS AI Suite II software, this was the only way I was able to get the actual temperature from the board. Are you able to touch the cpu block while it is on; is it actually getting hot. If it is 90 degrees you wouldn't be able to touch it for long.

Just had a look. I can perhaps touch block of the watercooler which is on CPU if thats what u mean? Saying that I can check BIOS temp to see how that compares. What should be the max running temp then of CPU?

horrorxpunk · 7 Apr 2013 at 14:39

In bios under water cooling, it will only show you idle temperatures I would say this should be no more than 10 degrees ~ above room temperature on your kit.

If it's really running that hot the water block on the cpu will be very hot to touch. Most likely the radiator would be also.

might need the paste re applying, could have dried up and isn't making good contact anymore

Bhogal · 7 Apr 2013 at 14:55

Cheers for the advice guys. Will need to get some paste and need to test the temperature. Currently on night shifts for the next four so may need to wait until I finish them now

I did go into BIOS which starting temperature was around 55 but every 1-2 seconds started increasing by 1 degree. Didn't see how high it went as I had to turn off machine

Will investigate further and see.

Thanks

I had a very similar problem with an AMD chip it would continually overheat no matter how well the heat paste or heatsink was applied did not happen with a new CPU though. Replaced with exactly the same chip though. Just a possibility. In fact forget that because the chip was about 8 years old
