This is probably one of the MOST BADASS heatsinks around... OCIA looks
at the ThermalRight SLK-800...
No fan was included with this heatsink, which leaves you free
to use any fan you wish. This heatsink will accommodate 60, 70 and 80mm fans.
You can even use those huge 38mm tall 80mm Delta fans if you choose. All of
this is possible via the adjustable fan mounts.
