Throughout the review I was really rooting for this heatsink. I was originally optimistic at the idea of having a passive heatsink and consequently my optimism was definitely not misplaced. Thor's Hammer turned out to be everything I expected of it and it really took the cake in terms of performance compared to any other heatsink I have reviewed thus far. Thor's Hammer even beat out the TRUE by a whole degree in the idle overclocked test. To say I was amazed would be a harsh understatement. If you are honestly looking for a good silent setup, Thor's Hammer by Xigmatech is the way to go. This heatsink will run you about $64.99, which isn't too pricey either. It's only cheaper than a TRUE by $5, though I'm not too sure if it beats it out price/performance wise but it comes close than any other heatsink I've seen yet and it uses a direct heatpipe touch, which I have up until now not seen a decent performing heatpipe touch heatsink. Overall, the only con I can really speak of is the tough installation I had with it, but apart from that this heatsink performs very well.
