Despite these troubles, I am rather happy with this fan. The design is extremely solid and it looks very nice. Although, I wish there was a way to shut the LEDs off independently of the fan, but that is something I can live without.
The fan does a decent job of keeping my CPU cool. I run about 39/42C now, which is pretty close to what I was running with my old heatsink and fan. I have no really good way of determining if the aluminum of the casing is acting as an additional heatsink, but since there is a metal-to-metal contact running all the way from the casing to the CPU core, it certainly cannot hurt anything.
