While this heatsink isn't the best on the market, it does manage to keep your system at a very tolerable temperature even when you try to torture it. Add to this the reasonably quiet noise levels of the fan and a retention system that will make you drool, and you've got a good choice for some good cooling.
But I am still just a little concerned about the copper core of the sink not being centered over the processor. While it doesn't seem to hinder the performance, it just doesn't seem quite right. Besides, I'd be willing to bet that once this manufacturing flaw is worked out of the unit, that it may even cool better than before!
Price wise, the Dr. Thermal line is right in the ballpark of other coolers. It's priced at US$29, so is not overly expensive. I would prefer to see the YS Tech fan on this cooler, but that is really a small thing.
Bottom line...If you're looking for a cooler that is capable of handling the workload of an aggressively overclocked system, and also like the idea of never having to be afraid of cracking the core again, then take a look at this heatsink. It can handle the hot work and the retention system is a dream come true.
Retention system is outstanding
No fan grill
Heatsink not centered over processor core
