I may be just a tad bit late with this review seeing how the FOP-38 has been around for quite some time. This fan has kindly been provided to us from our good chums over at Sidewinder Computers. Back in the day, when the heatsink was first released, it quickly gained a reputation of being one of the best cooling solutions for your hot rod Duron or T-Bird. Boasting the ever popular Delta 6800RPM Black Label fan, this thing could cool even the hottest CPU's.
Lets take a closer look at the heatsink.
Not much has changed between the FOP and WBK series of coolers in the way of looks. Its almost like a generation of cars, one looks like a block, the other is smooth and curvy. Just like the WBK, the FOP-38 is constructed out of a solid block of aluminum. If I counted right, the FOP has 20 thin fins to help dissipate the heat. It would be 40 if you considered the fins on each side of the clip as separate.
