I got this one( Thermalright AXP-140) sitting in a box right now. Havent had a chance to install it yet. I'm still rolling the stock cooler at the moment.
Well the cooler is doin a great job. Before cooler idle 36c load 54, now idle 28 load 42c-43c & the new temps are with a multiplier OC to 3910Mhz. So for the price of £14 (bout $20) i would say it was a good buy....
