The Coolermaster V10 is not that great a performer and the configuration is odd. There is a horizontal fan right over the memory slots so that you cannot install memory modules that have those tall heatspreaders that sort of look like a comb. If you want to stick with Coolermaster, then the Hyper 212+ is your best bang for the buck.
Here is a link to a recent Tom's Hardware article with useful information about 10 popular cpu heatsinks:
ive had a friend that actually bought the v10 and have used it for a while now. dunno how long it was hanging on the mobo but when he took it off to upgrade the CPU the mobo was slightly warped.
i myself have a water cooled my computer but if i had a choice of choosing the v10 for less money and water cooled for a little bit more id go water cooled.
and tips on water cooling. just buy the radiator, pump, and res...the fittings, thread seal and tubing you can get at a local hardware store for pennies on the dollar. ahh and just use anti freeze...dont bother buying the expencive fluids its all the same
