Most heatsinks in its price range don't look as nice or have LED fans. Some of them don't even come with fans that push as much air as what is included with the Dark Knight. Mounting the heatsink was not much of a challenge like some I have had to tackle. I must say though, with as many heatsinks as there are on the market now, I am a bit disappointed that Xigmatek never gave you the option for a second fan on the heatsink. It's also the fact that in my heatsink reviews, I have only encountered one other heatsink not capable of having a second fan. This model from Xigmatek only uses 3 heatpipes in a U shaped configuration to remove the heat generated by the CPU. While this may suffice with a CPU that does not dump as large a heat load, it just did not have the ability to keep the i7 920 cool. As a stock replacement, it would do fine. But for the overclocker or enthusiast looking for temperatures much lower than the stock cooler, the S-1283V Dark Knight just did not deliver on that front.
