Hot overclock

[kronos_100]

Hi, I'm pretty new to overclocking and I seem to have got a stable overclock but my CPU temps are hitting 90c on load, I end up quitting prime in-case it gets any higher and kills my cpu. My idle temps are 50c, the ambient temp is about 20c.

My settings are:
Ratio:20x
BCLK: 190
DDR Freq:1523
CPUVolt: 1.275v

My spec:
Rampage III extreme, I7 930, Corsair Dominator GT, DDR3 PC3-12800(1600)CAS 7-7-7-20, 850W Enermax Revolution85+, Zalman GT1000 Case, Xigmatek Thor's Hammer with two Apache Black Super Silent fans.

I was thinking about reseating my cpu cooler but as that maybe a pain in the arse I was wondering if you guys had any other ideas?

Cheers for your help guys,
The only other volt I set was the CPU PLL Volt - 1.90 also tried 1.85, no difference.

I used Arctic Silver 5 and applied a thin layer rather than a small pea size drop.

No doubt about it the air flow in the Zalman GT1000 isnt great but there is little difference when I open the case up.

Just tried it on stock speeds and I'm getting 43c idle and 70c on Prime...is this normal?
