Specifications:

Compatibility:  780i motherboard (all reference builds)
Material:  Aluminum

Description:

The Viper John 780i Mosfet Heatsinks coupled with an aftermarket air cooler or chipset waterblock is a great solution for those that wish to replace the stock cooling solution on their nVidia reference 780i motherboard. 

The mosfet heatsinks mount using four of the stock 2mm insulated spring screws that are used to retain the stock 780i chipset "FrankenCooler".  After cleaning the mosfets of any old TIM apply a dab of either Arctic Silver Ceramique or Arctic Cooling MX-2 compound to each mosfet and install the heatsinks.  If you thread a round tooth pick part way into each threaded heat sink hole they make a handy pilot for lining the heatsinks up with the mounting holes in the motherboard.

Tech Notes:

• The single row mosfet heatsink base is deliberately crowned outward at the center. This is to help compensate for the motherboard bow that occurs in this area when a CPU cooler is installed...even when a backplate is used.
• If your motherboard uses thermal interfaces pads (typically found on the stock mosfet strip heatsink) do not reuse them when installing either of the Viper Vcore Mosfet heat sinks.
