i5 3570K high stock temp

[iTonyy]

I'm currently running a i5 3570k on a asrock extreme 4 cooled with a H80i at stock settings.

After about 6 hours of Prime95 blend, the temp rose to a max of 87 C with a difference of 10 degrees between hottest and coolest core.

From what I've seen other people report, about 60 C is the average at stock settings.

I realize that Ivy bridge use a cheap thermal paste for the internal heat spreader so that can cause problems but I'm not 100% that its the problem.

(for further context, i have a single gpu that rear exhausts all in a C70 with 3 120mm fans on the front for intake and ambient is ~20 C)

Just wondering if theres anything I can improve on or maybe I just got a bad cpu

(considered undervolting but I do want to overclock it so preferably not)

Make sure the cpu block is properly attached... Are the fans on the H80i running at full speed?

87c @ stock, that doesn't seem right at all.

Did you make sure the pump & the fans are running @ adequate speed settings ?

That's quite high, I'm running an i5 3570 with CM Hyper Evo 212+ and at idle it's 34-36c. At load it's 49c~

yes its properly attached and i'm running both fans at 900rpm but that would maybe at most make it ~70C

Try to reapply the thermal paste.

Have you tried reapplying the thermal paste and reseating the cooler? Make sure it spreads evenly and that there are no bubbles in the thermal compound.
