In this review we have tested the Global Win WBK 38 Cooler and measured the temperature results with our test setup. Additionally you can listen to an embedded MP3 fan sound sample of the fan on the respective heatsink.

Name	Global WIN WBK 38
Size over all L/B/H	++ 75/64/70 mm The cooler is a little bit bigger than the socket – please visit Fit for Fan !
Cooling output	++++ 37 CFM (6800 rpm)
Noise level	— 46 dB (A) This fan animates to hear loud music. It’s nothing for sensitive ears. Listen to the sound:
Mounting	++ It isn’t very hard to mount the fan with a screwdriver but i’ve seen several easier constructions before, because the bracket is badly fixed.
Cooling results	++++ The cooling result was about 38 ° C at 1,75 Vcore and 41° C at 1,90 Vcore, nearly the same as the result of the full copper Kanie Hedgehog.
General impression	+++ The 300 gr. lightweight aluminium alloy WBK 38 offer very good cooling results. The reason is the very powerful but also noisy fan with a cooling output of 37 CFM and a the advanced aluminium core. According to the manufacturer you should attach the fan directly to the PC power supply unit and not to the mainboard connector cause of the very high power input of 3,84 Watt. This could be a problem on some mainboards which detects the CPU-Fan speed and automatically shut down the PC if no fan is present. In this case plug another fan like a case fan to the mainboard CPU-fan connector or get a newer BIOS with an option to disable the fan fail detection. This fan is also fit for using with Peltier Element ! Many thanks to Overclockers for this test sample.Pictures …
