Quite simple which one and why? http://www.scan.co.uk/products/ante...ce=google+shopping&utm_medium=google+shopping or http://www.scan.co.uk/products/cors...e-cpu-cooler-s775-1155-1156-1366-2011-am2-am3 For an i5 2500k.
The corsair is very noisy, the actual Antec equivalent of the H80 is a H20 920. But for a 2500K the 620would be fine, and my choice due to the noisy Corsair fans.
