Your gonna be so happy with the DH-14. Amazingly cool and quiet. Ive been testing it on a 2500k the last two days and the temps didnt go above 56 degrees, in prime, stock settings but with silent mode in bios. Getting my own DH-14/2500k on monday or thursday for my lan rigg. Will be properly tested with overclocks then.
Unfortunately i cant help you with any suggestions for where to buy, as i live in Norway.
