New Build with hot CPU and cooler master hyper plus 212

I have an i5 760 on an asus p7p55d-e pro motherboard.

I just installed a cooler master hyper 212 plus.

When i load bios to default settings, with boot and idle temps are around 38-22 c depending on cores.
When i stress test small fft's in prime 95 i get around 63 one my hottest core and 55 on my coolest.

When i go into bios and do a very modest OC to 3.0 ghz with 160blck from 133 with the same 20 multiplyer.

Boot and idle temps are 44-38 depending on core.

Prime 95 small fft's my temps rise up quite a bit to 65 c

Why are my cores all running different temperatures by 10 c

Is this a problem with case air flow? defecting cpu//HSF? Bad thermal paste and/or application

I'm using prime 95 for stress test
Using cpuid hardware monitor for temperatures
Thermal paste is arctic silver 5

I did clean off the cpu from stock cooler thermal paste as well.

This is a very recent install so i know that the thermal paste gets more effective over time.

I was just hoping to get a 3.4-3.6 ghz with temps sub 70 pref low 60 under full load.

Maybe too much paste. What's your temperatures in speedfan and PCwizard? Temps not bad though.

Best solution

I would guess that the thermal paste is not spread across the whole cpu evenly. Probably explains the uneven core temps. Wouldn't hurt to try reapplying!

This is a good guide for applying thermal paste to HDT style coolers like yours...worked for me!
