I don't know anything about his cooler, but by the picture I can't see how much surface area the HS has...it doesn't look like much. Dual fan idea is pretty cool though. Also, most coolers are made for cooling stock computers, not OC'd ones with higher voltage. There are lots of coolers that look pretty cool, but don't hold up under overclocked computers (especially modern, super hot ones)...take a look at the Golden Orb..lol.
If it were me, I'd pay the extra money to get a known, tested, and proven reliable cooler. Just my opinion though.
