Update :
OCZ Ram cooler
I bought this ram cooler after having one previously and being impressed with it. However three things let it sown imo. The fans are a little 'whiney' and get a little irritating after a while and they also don't exactly push a lot of air. They are also blue led versions which dont fit in well with my build at all. So I got a couple of replacement fans:
These 60mm fans are almost twice as thick as the original fans but push a lot more air through without being 'whiney'. They are however very loud as you would expect being 60mm but run quite @60% speed while still pushing more air than the stock fans. Fitting them was relatively easy as I just bent out the original screw holes and then bent them over the top of the new fans after they were replaced. So thats the blue led, noise and airflow problem sorted - now onto the aesthetics.
The main unit, while having a fantastic chrome effect sticks out like a sore thumb in my new build so something had to be done about it. A little sanding, priming and spraying and hey presto, a more sullen but subdued look:
