With a trio of heatpipe direct touch CPU cooler reviews under our belts, I can definitively say that the tech is quickly catching on and spreading like wildfire. I am standing strong behind my statement from the last review of a H.D.T. cooler that I think this is the direction most CPU heatsinks will go in the future; much like the way nearly all CPU coolers use heatpipes nowadays.

Today we are going to take a look at the HDT-SD964 from XIGMATEK. Unlike all of the Heatpipe Direct Touch (H.D.T.) coolers we have looked at thus far, this cooler does not use a 120mm fan. The HDT-SD964 uses a 92mm fan and is a little shorter than the others. This will allow the cooler to be placed in smaller enclosures like 4U server chassis’ and equal sized media center cases.
