After all tests were complete, I can say that I was fairly impressed with this heatsink. When I saw the aluminum body, I was not expecting this level of cooling from the XDream cooler. It was a pleasant surprise to be wrong in this instance.
Another little piece of information that may make this an even sweeter proposition is the price tag. I found one listed at NewEgg for a paltry US$15! That's right, we're talking cooling potential that in the same ballpark as the mighty Swiftech MCX462+ at a third the price. This makes things look even more interesting, don't you think?
But of course the sink isn't without faults. The clipping mechanism was a big disappointment since it is highly possible that you'll break it in the future. And a fully copper sink would have been nice as well, but the results are still not too shabby.
Bottom line...If you happen to be in the market for a heatsink that gives very workable cooling, adjustable fan speeds that are externally controlled AND happen to be looking for this item for a small amount of cash, then look no further than the Cooler Master HAC-V81 HSF. You certainly won't be disappointed with the temperatures you get, but you might want to save a few dollars for replacement clipping mechanisms.
Excellent cooling prowess
Very smooth base
Adjustable fan speeds
Clip metal is very flimsy
