My CPU keeps going over 90C which is causing my computer to switch off. I have cleaned my hear sink and fan but the problem is still happening. Is there anything else I could do which could be the problem to over heating?

Welcome to PCHF KillAllTrends!

That is a very high temperature and i wouldnt run it at that!

has this suddenly happened or been going for a while?

Is the Heatsink installed correctly and are there enough case fans?

It suddenly happend. It normally runs at around 50 to 60

The heatsink is installed correctly, I have 2 fans and the CPU fan is running at approx 2720rpm

Try taking off the HSF cleaning off the thermal paste/pad and re apply a little thermal paste (arctic silver is fantastic) and make sure its reseated properly

Give the case a good clean and try a little cable management to improve airflow, after this check the new temps.

Have you changed any voltages in the bios? if so revert them back to what they were. infact, you could try clearing the CMOS just to make sure (either using the jumper or take the battery out for a bit)

Lastly if all else fails, see if you can get a couple of temp probes/IR thermometer and check that it is actually running that hot, if it just happened suddenly and you've cleaned everything and the HSF is correctly seated I suspect a bad temp sensor on the motherboard.

Hope this helps

Thanks to you both for your help. Got a tin of air duster out and used themal paste. Now running at about 35/40C :oD

Great news!!! Glad its sorted Kill
