What a mouth-full!

Anyway, I'm planning to get this and was planning to use an Artcic Freezer 7 Pro, but I've read that the NB heatsink on the board is quite big and the Pro doesn't fit very well (actually touches it). Can anyone recommend a decent heatsink (around the same price) that will fit for sure?

Many thanks

Yup, the stock cooler.

I have teh DK X38-T2RB (with the copper piping)..

I had a Freezer 7 Pro lying around and didnt feel like ordering another CPU cooler so I stuck it on.

To answer your question, I actually had to mount it the opposite way around (so that the fan is blowing air to the front of the case). I moved the rear fan the other way too to get cool air onto the fan.

I had to bend the bottom 2-3 fins a little bit and the fan touches the NB cooling heatsink. It's a REALLY snug fit but it works fine.
