[SOLVED] CPU overheating - already replaced thermal paste

[mrdhwr]

Hi,

Strangest thing: had a virus, (think) I got rid of it, but can't properly scan my PC because my CPU keeps overheating...
Pretty much instantly goes up after booting, hangs around 85 degrees, after 2 or 3 minutes it reaches 94 and begins hogging.
Already replaced thermal paste, literally no difference. Checked cooling system (Corsair Link), pumps and fans still running as expected.

Mobo: GA X99 UD4
CPU: Intel 5820K
Cooling: Corsair H80i
New thermal paste: Arctic MX-4

What could be the cause?

Regards

Is it really? Physically check via both tubes.
Good flow: "I can't really tell a difference between them", or "I think this one is a little warmer than that one".
Poor flow: "This one is definitely warmer than the other. It's a night and day difference."

The other obvious thing would be mounting hardware. Do you have good pressure from the CPU block on the CPU?

Aha, I didn't check this. Definitely poor flow. One is definitely heating up, the other cold as ice.
Can I fix this? Or should I buy new cooling?

This is a "buy a new one" situation.

What kanewolf said. You've no other option but to buy new.

Got it. Thanks for the help!

Don't take this the wrong way, as I actually managed to do this yesterday (even when saying to myself; remember to remove before attaching post paste).
Still managed to do it, as I got distracted by a phone call mid build

Did you remove the plastic on the block? It's is a common accident / mistake.
