CoolIT Ram Fan Memory Cooler Review
 

It's always nice to review a product that does exactly what it advertises, and the RAM Fan succeeds in that. It will be especially useful to overclockers who often push RAM voltages to high levels and would benefit from active cooling. With a price of only $20 US and installation that only takes a few minutes, I can't see any reason not to highly recommend this product.
