I want to change the TIM on every one of those...
Twin Frozr III's

Now that's what I call a rig! Very nice!
I will agree with HippieTech, tho. Why are 2 of them running so much cooler than the others? The same GPU, same setting, uniform spacing for airflow, and they're ranging from 59-86C?!
The one with with the fan on the open side is probably coolest then the rest gradually run hotter as they suck in the air exhausted by the card beside it until the last one which runs the hottest.
