I gotta say this has been the lowest quality of Toms reviews that I've read to date....
As far as mounting goes, they need to rate ease of installation on both AMD and Intel systems. And as far as metal shavings go as mention in certain coolers, thats why I always test fit the cooler before mounting to get rid of such issues. Not to mention, orientation of the cooler does have an effect when installed in a case. A lot of the coolers I've seen can be pretty much mounted facing any direction. But it most mid towers optimum direction would be blowing towards the back of the case, so the rear fan can pull air directly out, with a little assistance from any PSU fan pulling from the top.
There is no mention of what paste or grease was used. What was ambient temp at? Not to mention there are CPU's out right now that have higher TDP and heat dissipation than what the qx6850 has. Temps seem rather high, even compared to what i've seen on some processors. And when you consider the fact I got an old athlon XP Palomino to run at less than 55c under load with an old copper evercool hsf that says a lot.
A case with a board mounting plate that had a hole cut out beneath the socket for mounting hsf hardware would be awesome.
As far as cases with removable tray's thats a good point, even the tray on my raidmax smilodon is removable for mounting. So I think a baseline case situation should be taken into account.
I notice they failed the Nirvana yet it has some of the best cooling performance in the bunch. As far as mounting on that one, I'd give it about a 7 or 8 for AMD, could be difficult depending on case and mobo combo, plus the amount of weight on the retaining ring. As far as mounting on Intel rig goes, I'd say a 5 or 6, since the screws could be difficult to get to for tightening, and as far as possible metal flakes, thats what compressed air is for. And as far as noise in a closed case goes, I can't really hear it over the other 2 120mm case fans, and it's not loud enough to me to be distracting, and since I'm nit picky about such things I can back that up.
