Nanoxia deep silence 6 is also an option. It's build quality is about as good as caselabs.
I've not even heard of this brand - I'll check it out - and compare to Be-Quiet Dark Rock Pro 4 which I'm happy with.
>>>OK, since the last post - The internal case fan was removed, creating room for 2 x fans on each DARK ROCK cooler. The best OC result I've had for 2 x Xeon_E5_2690_v2 is base clock @ 105/106 X 33 @ 1.020_V_EIST ON_or__1.030_V__EIST_OFF
Hottest core was under 60 C with P95 29.4 well over 2 hours.
BCLK 106 needed to be 105 to start with, then nudged in BIOS to 106 ----If there was a crash at higher for any reason such as low V-core it was necessary to go back to 105 BCLK then >>>106 but all is well and temps are great under P95 stress.
BCLK 113 was possible but temps went into the 70's on hottest core and for not much more than 500 extra PASSMARK points -- So BCLK 106 X 33 EIST OFF gives great performance for both CPU & thermals.
