"The last time I tested a heatsink with a 38mm thick high-speed Delta fan my finger got sucked into the 'blender of death' and there was plenty of blood. Be smart, keep that fan grill on at all times. The Model P heatsink from Dynatron is a full copper skived heatsink with a very powerful, and very noisy Delta fan. Heck, the fan is larger than the actual heatsink so that should tell you something. These 38mm thick Delta fans draw 0.83A so it is better to plug them into the power supply via a Molex pass thru cable adaptor. We haven't ever had a fan blow a fuse on one of our motherboards, but I have heard a few accounts of things happening in the long run which may be due to the high current draw."
