Globalwin CAK4-86 Copper Heatsink Review

True performance coolers are starting to fall by the wayside as consumers have gradually picked up the call to arms for quieter, low-noise cooling over raw fan power, and high decibels. There are a few die hards, or just die [H]ard overclockers who will always aim for the loudest, meanest, and best performing heatsinks in their search for extra Megahertz. The CAK4-8XX series is a chameleon of sorts in this area, Globalwin sell the same basic heatsink with different fans for different purposes.

We've already looked at the two low-noise adaptations of this heatsink, so let's now focus on the high-noise version. The CAK4-86 comes packing a 38mm thick Delta fan which draws an impressive 0.81A of current. For the longevity of your motherboard, it is better to power this baby directly off of the power supply, and not via the fan headers. Since the copper skive portion of the Globalwin CAK4-86 is just 70mm in size, Globalwin have added a 70mm-80mm fan adaptor to the package. The fan adaptor is made from translucent blue plastic and features an ingenious curved divider down the center. It is a bit fragile around the screw holes, so care must be taken if you intend on trying out a lot of different types of fans.

    Looking down onto the heatsink with the blue fan adaptor in place, the heatsink has a very nice appearance. The fan adaptor has one downside, and that revolves around the plastic itself. While reviewing the GlobalWin CAK4-86 and CAK4-88T we swapped out different fans several times and this caused cracks in the plastic around the screw holes. Obviously, if the plastic which is supposed to be holding the fan in place fails, that poses a potential problem. A more flexible/durable plastic would be a good option to consider for Globalwin, or perhaps some material reinforcement around the screw holes to prevent cracking in the first place.
