Hello,

I've got a i7 3770K with a Corsair Hydro Series H60 CPU Cooler, on a GA-Z77X-UP5TH motherboard, which has been working fine for 18 months.

This morning, after a few minutes on, my computer started slowing down and eventually turned itself off.

I turned it back on and checked the CPU temperatures, they were in the high 90 degrees.

I've checked that the CPU Cooler fan is still working (it is), and (properly) change the thermal paste coat.

Turning on the computer and checking the BIOS readings, letting the computer idling, the temperature comes back up (to at least 90, I turned it off when it reached that) in just a couple of minutes.

Wondering what is the cause, and what can be the solution? It seems like a some truly insane overheating even with a cooler not working properly. Could this be the CPU not working the way it should and heating up more than normal? If so, is there any solution other than a new CPU (which I don't mind changing if I know that's the cause).

Thanks in advance,

Julien

The fan might be working, but it's more than likely the pump failed.

Confirm the unit is plugged in correctly; if so, than replace it.

Do you hear a clicking or cracking noise? your pump may have some air bubbles in it

Can't believe I didn't make the connection earlier:

A few days ago, I noticed a strange ticking noise somewhere in the case.

I've just checked and it seems like the noise was coming from the pump. It stopped now (though the overheating is still happening).

I might just try replacing the pump. Thank you for your answers

Yeah that is for sure your pump then. The only thing that you can try is by taking off the fans if you have them in push pull and try cleaning the dust. A lot of the time I will find a good layer of dust on the pump itself not the fans. So try that if not talk to corsair for an rma because even if you bought the h60 when it was released it would still be under warranty

Thanks all, it was indeed the pump. I didn't wait for an RMA and got an H75 instead because I needed it ASAP.

35C seems like a much more reasonable temperature!
