A traditional CPU fan would help. In a tower case, so would a top fan. We're just optimizing for cross-flow cooling in a radiator rig.A cooler master haf x evo lol. (I am only laughing because that is the case I am running my MSI unify and 3800x in (oc'ed to 4.4 all core FLCK 1900).
That setup is pretty dam close to an open air test bench.............
You slap that board into a standard case, install a normal CLC cooler on it, and watch the thermals on the VRM's sore. ( Using a CLC eliminates the CPU fan which traditionally helps cool the VRM's)
I should also remind you that all our awards are qualified by the target market. We believe that this is as good as it gets at $160. The ASRock board we recommended was as good as it gets at $200 (actually $195 but what's $5?). We also have best-of-the-best (no price limit), but what we NO LONGER have (for several years now) is different awards for different qualifications.
