Ok, this is how is gon' be.
Deshroud 7900xtx Red Devil, Test 3x120mm bank of all 4 fans.
There's no replacement for testing, because performance may vary quite a bit depending on air turbulence/ impedance characteristics of specific heatsinks.
The plan is:
RPM normalized run through
Temp normalized
Noise normalized, tp4 can't measure below 30db, it's also unrealistic to measure lower, because of perceptual issues.
Perceptual silence normalized, by ear (how annoying the sound normalized)
Bearing noise evaluation, by ear.
--Thermalright C12 Black, 1500rpm, $4.30 each, This is a really good fan, it's entirely CFM+Turbulence optimized for its rpm range.
--Arctic P12 Max FDB 120mm, 3300rpm, Cheeeeeep, $10 each, German engineering (so they advertise)
--Scythe Grand Tornado, 3100rpm, FDB, Cheep motor, Glass fiber plastic + housing, $15 each
--Antec Nova 120mm 3200rpm (just came out), 3phase motor (precision rpm target, useless but cool), glass fiber plastic, $21 each, very aggressive value'proposition.
The vaon is likely produced by the same oem that made the overpriced Phantek T30, which also has 3phase + rpm target.
T30 is way overpriced.
