I just installed an xp90 couple days ago on a 754 msi neo platnium mobo. I upgraded to 64 bit,so I said hey lets get this hs. Because I like how thermalright hs look and the clip on fan design.
When I first got it I was like WOW this is big and reminded me of the starship enterprise. But it was friggin light as heck like a can of dr pepper. Good thing I didn't get xp 120.
I just followed the instructions on installing it,since I never install these type of heatsinks.
I removed my memory from slot 1 before installing though. It made it easier for me. But note after it's install you can use slot 1 2 3 without any problems on this board.Hooked up the retention module.
Also I think I hooked this thing up right? Because, it wasn't going to fit the other way since the extension of the hs would hit the videocard cooler.
Fans are a easy to switch off.
