From the top picture you can see that the Cak-II 38 has a very long cord so it can plug in just about wherever you wish. Mainly though it includes a 3 to 4 prong adapter so you can power the fan using a 5v connector and not risk burning out a motherboard header as I know many of you have done before when using a high speed fan as this one. Also it has a 3-prong connector which goes to the motherboard so you can still monitor the fan speed. Now tell me, why don't all cpu cooler makers include this? It is nice to monitor the fan speed. Just a nice added touch from Global WIN.

Installing the Cak-II 38 was pretty much straight forward and just like most others. First attach the back clip over the motherboard catch, gently lower the heatsink on the cpu and use a flathead screwdriver to easily guide the front clip on the motherboard catch. At first I suggest to try fitting a screwdriver in the front clip so you know it's the right size and it provides a good-secure fit. You don't want to have it on the cpu then realize you have the wrong size screwdriver.

Being an all copper heatsink it does have the micro-fins that many current heatsinks have. These however are far more sturdy than most and not nearly as easy to bend. Plus I tried using a magnifying glass to get a closer look at how the fins connect to the bottom of the heatsink and the best I can tell is it appears the fins are carved out from copper because they look to be a continuation from the bottom. *I confirmed this with Global WIN and yes the fins are carved out so what we have here is a true one-piece heatsink! That's a major plus and means better performance than a heatsink which has the fins soldered to the base. This way allows for better heat transfer.
