Still not getting very good temps with H80i...

[jimbo]

Bought a H80i, installed it, temps were crap, bought some MX-4, applied the new TIM, temps are now better but still pretty crap for a cooler that cost amost £80 (inc. P&P).

Overclocked to 4GHz, I get high temps of 64 degrees on Prime95 with the voltage set to 1.1v. I can't lower the voltage anymore as it becomes unstable.
Although these temps are very acceptable, I feel they could be better seeing as a pal of mine is using a H100i on his 3570K and is getting 52 degrees MAX @ 4.2GHz using Prime95.
I know the H100i is a better cooler but I wouldn't expect it to be more than 10 degrees cooler and on a higher clock speed.

I've tried re-seating the pump block but it made no difference...

Does anyone have any suggestions as to what I should/could do or are my expectations unrealistic?

Thanks in advance...

What temps do you get at 4.2Ghz?

dont forget the h100i has double the surface area which allows to to cool twice as much as your 80 and twice the fans
thats why i chose that over the 80 even for a little more on the price. its worth it im getting lower temps with a 4.3 OC than your OC
i think your temps are ok. they are not in the dangerous level so its all good
