A small update regarding my BlackRidge. Got it out of the Dan A4 yesterday, 4 out of 6 heatpipes weren't soldered correctly
so I sent it back to alternate.
Interesting sidenote: I put my old C7 back in the case, but this time without the mobo's i/o-cover, results as following:

Due to it's heatsink fins facing the i/0-cover, the mass amount of hot air is now coming out of the case at that point. Of course there is some hot air rising to the upper part of the case, but it's way less than with the cover in place. And low and behold, 8,6% less rpm at roughly the same temps. I kept it that way
