Thanks Intrepid.
I'm going to run an 8400 or 8500 Wolfdale with G.Skill 6400 HZ 2x1gb . Will i be able to just plug this ram in and go (no overclocking at first) without voltage issues?
Thanks, Danny.

"The Ultima-90 is not the best air cooler we have tested. That distinction still belongs to big brother Thermalright Ultra-120 eXtreme. Where the Ultima-90 carries our CPU to a stable 3.90 GHz, the eXtreme pushes it to 3.94 GHz. The eXtreme also manages a few degrees better cooling than the Ultima-90 at higher overclocks. However, in all other respects the performance of both coolers is all but the same. The Ultra-120 eXtreme is bigger, heavier and costs about $65 retail, where Ultima-90 costs about $50. However, the Ultra-120 eXtreme remains the better performer. You will need to decide which attributes are most important to you. Beyond the Ultra-120 eXtreme, we do not know of an air cooler that outperforms the Ultima-90. Several other top models match its performance, but they don't outperform it"

BTW, the Ultra-120 Extreme is the best air cooler currently available (I use it). Nearly all reviews say nothing cools better (requires a fan):
