I'm doing this for my own personal experience, but I figured I would share it.
ZALMAN CNPS7000B-AlCu LED
VS
Thermalright XP-120
(Attached fan: http://www.newegg.com/Product/Produc...82E16811998124)
Now I know the price difference is roughly $30 for the Zalman and $50 for the Thermalright and the fan size for the Zalman is 92mm and the fan size is 120 for the Thermalright... so most people would think that the bigger is better, and the cheaper is going to be crappier.... lets go over some basic comparisons.
Brand: Zalman/Thermalright
Price US$: $30/$50
Fan Compatibility: 92mm/120mm
Material: Copper base with Aluminium surrounding/Nickel plated Copper base with Aluminium
Heatpipes: 0/5
Dimensions: 109 x 109 x 62mm/110 x 125 x 63mm without fan
so should you fork out the extra $20 for the "better" cooler?
Over the next 2 weeks I will be testing the two CPU coolers with an overclocked E6300, temps will be read with Everest Ultimate Edition, Artic Silver 5 will be the thermal compound of choice.
