IceRiver Ice River KS0 KS-0 KS 0 Pro or Ultra Power MOSFET Cooling Upgrade.  4 Pieces Copper Heatsink 6x6x5mm w/ Thermal Tape
4 Pieces

The KS0 Pro/Ultra power circuitry was designed for the stock 100w power draw.  If you Overclock your KS0 Pro/Ultra and upgrade the power supply, you will probably put 150-200w through it.  It will run hot.  In addition to adding cooling fans and ducts, you can also add heatsinks to the power MOSFETs.  These 6x6x5mm heat sinks are a good fit and include Pre applied 3M 8810 thermal conductive adhesive tape backing for easy installation.  Or if you prefer, you can remove the tape and use Thermal Glue instead.  

Adding heatsinks to the power MOSFET chips lowered my power stage board temperature by 5-10 degrees C.  (I had previously installed good vents, ducts and fans)

Installation is super easy.  Just open the bottom panel and attach.


These can also be used on many other board or chip or GPU applications.
