HAF X NV-942 VGA Cowling Air Flow Mod

Postby ZelmoQuad on Tue Mar 22, 2011 9:52 pm

I noticed a 2-3 degree temp difference in my 2-way SLI cards and started thinking back about the assembly.

During the initial assembly of my new Chassis I noticed a potential air flow barrier with the VGA cowling. The bottom wall of the cowl covered the intake of my lowest SLI’d GTX 580. The gap appeared to be 1/16th” between to the two surfaces. Being fussy about temps, and believing VGA card intakes should have velocity stacks, I decided to cut away some of the cowling to insure there would be a uninterrupted air flow to the GTX580 fan.

I achieved a cooler and more matched temp between the two cards. This was a good mod for me. In game (BFBC2, everything maxed) both card temps remain, under load, at 51-52C with fans set at 70%. Temps drop to 35C in 30 seconds when I stop the round and stay in the game. When I am totally out of the game and idle at the desktop, my temps knock down to 30C.

This box cools like “Waddah”

This is an easy mod, can’t hurt, and it will make your mo-sheen lighter, theoretically. :cheers:
