Just noticed that Corsair have switched to marketing the Coolit CPU Water Cooler, re-badged of course, as a result the cooler should be more generally available.

To anyone that doesn't know, the Coolit kit is compatible with most popular CPU's, even the new AMD FM1. The quality and ease of fitting is first class, I didn't even have to replace the standard CPU mounting back plate, although one was supplied with the kit, and yes, the water pipes are plenty long enough.
This is a sealed for life unit, requiring no maintenance and is totally silent in use.
You will require a case with a 120cm exhaust fan hole for the standard radiator.
I have been using the basic Coolit kit (no fan supplied, I used the standard case fan) since I built my AMD 6 core system and I have never seen the CPU temperature reach 40C even though the system is running Linux, a Web Server, and VirtualBox running Windows Server.
In summer CPU temperature tends to be around 29C in normal use and in winter this tends to drop to around 23C. The added bonus of not having to have the sound of a jet engine to cool the CPU cannot be overstated.
