X-bit Labs has compared 13 140mm fans from 9 different manufacturers, you can check it out over here.
The fans of this size are currently pretty popular. It is not only because processor air-coolers more and more often use 140 mm fans these days, but also because they gradually replace the common 120 mm fans inside contemporary system cases, which is exactly what happened back in the days with the 92x92x25 mm fans. This is a pretty logical process, although it will be some time before 120 mm fans go away completely. Nevertheless, we believe that 140 mm fans will continue increasing their presence not only in the CPU cooling products, but also as system case components.
Well, today we are proud to introduce to you 13 fan models from nine cooling solutions manufacturers, such as: Deep Cool, Evercool, Nanoxia, Noctua, Noiseblocker, Revoltec, Scythe, Thermalright and Xigmatek.
