In this review we have tested the Global Win CAK 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 CAK 38
Size over all L/B/H	+++ 60/60/70 mm The cooler is just as big as the socket !
Cooling output	++++ 37 CFM (6800 rpm)
Noise level	— 46 dB (A) This fan animates you 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 36 ° C at 1,75 Vcore and 39° C at 1,90 Vcore, great !
General impression	+++ The 450 gr. heavy full copper CAK38 cooler exceeds all present results and for this reason it’s the first cooler getting the ocinside.de Overclocking Dream award ! Of course there’re several fan with less noise and most cooler with lower weight, but the size and cooling results is more than good. 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 …
