Installation was child's play, at least for my socket 939 CPU. You simply interlock the mounting clip pieces around the base plate and clip the heat sink onto the stock motherboard retention frame. You do need to check the clearance on your motherboard capacitors and any heat sinks sprinkled around the motherboard. On the DFI LanParty UT nF4 Ultra-D, one of the heat pipes barely cleared a mosfet heat sink. Low profile coolers do have their drawbacks, and the CNPS8000 is no exception. Users with Intel CPUs must replace the retention frame.
