Top Ten fans ... The new SilentWings weren't in the test but I'd put them in the top 3
Phanteks PH-F140HP/TS/SP
Noctua NF-A14 FLX
Noctua NF-A15 PWM
Noiseblocker B12-2
Noctua NF-P14 FLX
Scythe Gentle Typhoon 120-12
Noiseblocker M12-S1
Corsair AF120 Quiet
Corsair AF120 Performance
Thermalright TR-TY150
If ya take a Noctua Cooler and replace the Noctua fans with Phanteks, CPU temps drop by a whopping 6.3C. We buy Phanteks fans by the dozen when they on sale w/ rebates for $10. Usual price is 412-13 for the 120s whereas be quiets are usually $20. The Corsair's don't come close to the Be Quiets or Phanteks.
