I'm not a reviewer but I have had Gentle Typhoons and can compare them to my new Noctua NF-A12x25, and the Noctuas are way more silent.
The GT fans have a very special and annoying hum to the motor that really bothers me, even at low RPM, and quality is less.
Which variant of gentle typhoon are you speaking of?
Well i have to agree on quality on gentle typhoon, especially on early releases.
I've 10 gentle typhoon (6 scythe AP15 1850rpm and 4 dark side AP60 2150rpm).
On my AP-15 original scythe version, 50% have some motor noise (from low to medium). Also noise @1850rpm is higher than my 2150rpm dark side version.
However on my AP60dark side, all are fine...and I'm definitely impressed by their noise level @2150rpm.
Don't get me wrong.
Noctua are pretty good fans. i wanted to highlight current state of the art of fan dedicated for radiator. Before nf a12-25, Noctua has no real competitive fan for radiator (even P12 was poorly gifted vs GT)
Noctua (like be quiet) fans have advantage to have very quiet (with very low motor noise) on low speed, with good reliability.
However, Noctua fans I own (P12, F12, nf a12x15, PPC 12, PPC14) tend to be pretty noisy at higher rpm.
I'm hoping that NF A12-25 @2000rpm is closer in noise to GT/Vardar than noctua PPC 120 2000...
