The Guru of 3D posted a review on the Asetek VapoChill LS

Processor cooling can be a hip thing to do. To go way beyond a normal overclock .. you need to cool that CPU below zero degrees C and that's where the Asetek LS comes in. It's the most expensive and noisiest cooling solution around. It's difficult to install as you'll need to mod your case, you'll have to do crazy stuff with your CPU ... but the result really is simple, you can cool down the processor with a -54 Degrees C cooling block on that AMD heatspreader and that my friends is such a fun experience you won't believe it.
