Bought in as ... Aww-what-the-heck-gotta-try-it after the reviews came in. Especially curious about what pressure it manages to push through a tough and thick 120mm radiator, considering building a really tight customloop to the working computer ...
Dislike showing loyalty to brands, but seems to have some kind of preference for these rackets. However, they have tested more expensive Vardar, Corsair Maglev, and they do not seem to keep the same quality on quality as this particular company dedicated to fans. That said, this should probably be taken into account in my reviews.
+ 6 year warranty. Breathe quality straight through.
+ Low noise all the way to ~ 60% PWM - 1400 RPM.
+ Very wide PWM range. 0-2000 + RPM. Stays at 0% PWM.
+ Moves a senseless amount of air even at lower RPM.
+ Good accessory package, as usual. (ULNA, 30 cm 4-pin extension, Y-splitter, lots of silicone mufflers)
- The price is great.
* Taste: Not available in sensible colors yet.
* Would have liked to see a 140 or 180 or 200mm variant with corresponding PWM range and performance.
% PWM: RPM (rounded) - TOTAL SUBJECTIVE comment;)
100: 2100 - Directly loud for a consumer fan. Good to know you have the RPM range, but would probably not want to drive it at these speeds.
90: 1950 - See above.
80: 1750 - Definitely not quiet, but compared to Corsair fans or Noctua PPC at 2000 RPM clearly less noise.
70: 1550 - "Propeller sound" surprises the engine noise. Audible from> 2 meters. Moves a really high amount of air even through narrower radiators.
60: 1400 - Obvious engine noise. "propeller sound" surprises the noise. Definitely audible from a few meters away.
50: 1200 - Very weak engine noise. Deaf sigh with weak "propeller sound".
40: 950 - Very weak engine noise. Deaf sus audible from ~ 50 cm.
30: 700 - Zero engine noise. Slightly audible ~ 30 cm away.
20: 500 - In principle, quite silent. Zero engine noise. Very weak rush of air moving if I put the ear next to it.
10: 250 - VERY quiet
0: 0 RPM - Stops completely
Tested via Corsair Commander Pro on an ASUS Zenith Extreme, Win10x64Ent-17763
As usual; YMMV
