Heres what I went for to do the conversion.
Thermalright HR03 Plus, Noctua NF-B9 92mm Fan, Akasa thermal tape, ArctiClean 1+2 thermal compound remover, Artic Silver 5, Black Pearl.

There were a lot of screws to undo and then there was a fight between me and the existing thermal goop about if the block should stay on or not. After a lot of wiggling I managed to remove it!

Removing the white goo was painstaking, especially around the tiny ram chips, patience and lots of ArtiClean was the key here!

All the RAM heatsinks are fitted, I originally planned to use Akasa thermal tape on all of them, but removing the existing thermal tape was really difficult. I only managed to use it on a couple of them.
Using a metal craft blade I carefully applied a thin even layer of Arctic Silver 5 to the core. The Thermalright heatsink came with a tube of compound, but I preferred to stick with my Artic Silver 5.

The glorious shining heatsink is fitted! This was a bit fiddly due to the weight of the thing, and the thumbscrews were hard to access, but patience is whats needed.

Idles at 45 degrees and sits at 60 under load in ATI Tool's stress test. Success! I reckon the Black Pearl watercooling is a gimmick, clearly air is just as good and much cheaper!
-Yes, I know my case is dusty.
