Those temps at those clocks with the cpu and cooler you have SCREAMS that something is not right. I know all chips are different but my 2500k is sitting at 4.7GHz with 1.34v and I never go above 75*C with a cooler which is not quite as good as yours. I would personally try a re-mount of the water block with new paste and make sure it's all fixed down securely.
Temps maxing at 72 now, after 5 hours test on P95. That's 44 m/plier and 1.2 cpu voltage.
Also fixed an annoying buzz from a fan.
I've got £200 max to spend on a graphics card now, anyone got a suggestion?
Was thinking maybe one of these; http://www.overclockers.co.uk/showproduct.php?prodid=GX-174-MS


Planetside mostly. Epic, epic mmo madness in a stunning digital environment. Lasers, spaceships, trench warfare, all that pixellated goodness and sonic mayhem. The whole game, on first few tries, seems to be just one colourful fps grind and not a whole lot more. It's a good game to get started on to showcase the new gfx tho, and I'll be happy taking part in the interstellar grind for a few weeks yet. looks like youve had more than a few troubles during the build,but im sure you will be relieved its done now,im currently saving maniacally for a xmas build which will be my first ever,hope i get done as well you have
i cleaned out the fans one time too, about 10months ago?
