Hi Guys,
I just about two hours ago installed Indigo Extreme. First off, as Skinnee said, you absolutely MUST pay slavish attention to the installation instructions. On my first attempt I got the ETI a little off center and thought I could lift it off and reseat it - WRONG. Reflow did not go right and the resultant temps were in the 80's.

Second attempt and I really took my time to get it right.

This stuff kicks Butt. My heat killer was installed previously with MX2. From MX2 to Indigo Extreme I realized a good 4c drop.

Indigo Extreme takes TIM to a whole new level. Expensive (especially when you have to do it twice ) and a pain to install but it is majorly worth it. Any overclocker who is looking for that last few degrees needs to put Indigo Extreme at the top of their shopping list.
