Noctua NF-F12 iPPC 2000 IP67 PWM 120mm Air Cooling Fan, 12x12x2.5cm, 12V, 2000rpm, 31.5dB(A), Compatible with Desktop, Laptop & Other Small Electronic Devices

At roughly 25 dollars a fan, or even more if you want to replace the brown rubber pads (fortunately I already had black ones from earlier purchases), these are not cheap fans. There is no RGB (if that matters to you), like mentioned before the included pads are brown, and the fan is not capable of growing legs and dancing to the song hello my baby hello my honey hello my ragtime girl.However they have incredible static pressure, best in class even. As the title says limited to 1500 rpm are incredibly quiet, I clocked seven of them at 40-45 whole dbs measured at an exhaust port. They are black not brown, beige, or even gray. The internal components are all but dust proof, and water proof I guess but not planning to test that.... Lastly they can even go up to 2000 rpm if heat gets out of control, but you really shouldn't ever need them to go that fast.Simply put, if you want the best 120mm fan you can buy (especially for water cooling radiators), stop looking you just found it. There is a cheaper version of the same fan without the IP67 certification, and there is a non pwm version, but I would rather spend a few dollars more and get the full features. There is a brown and beige version too in case you really like ugly fans.You can also find this fan in 3000 rpm, but gonna be honest... you really shouldn't need a pc cooling fan to run higher than 2000rpm.... even that is probably indicative of a issue that needs addressing (low water flow, fans not properly installed, components overclocked too far, etc etc). Unless of course you live somewhere with insane ambient temps like 35+ celcius on a normal day, then maybe 2000rpm is a good idea.There is however one tiny complaint.The logo facing side (exhaust) on these fans have these curved plastic blades. They have a tendency to bend and warp very slightly if you are running fan cables around the body of the fan and have them installed right beside each other.... specifically on a radiator. This is a pretty standard thing to do to minimize excess fan cable length and keep a clean build. Performance wise there is no impact, but if the pressure is too great it might cause the blade to bend in and clip the fan rotors making a very unpleasant noise.Just something to be aware of, with careful install it's a non issue, and if you don't care about excess fan cable length it isn't even a thing.If you want RGB fans though.... my advice is get some Lian Li Uni fans if you can find them at retail non scalper prices, or go with EK Waterblocks Vardar fans.

Si buscan unos ventiladores de batalla, estos son los indicados, la verdad empujan aire como no tienen una idea y son buenísimos. Son caros valen el triple que lo que cuestan otros pero lo valen. Con estos ventis, bajaron las temperaturas de mi PC unos 5-7 grados normal y haciendo esfuerzos noté que le bajó 10-12 grados. La compu está mas fresca que una lechuga.

The IP67 rating on these fans was the deciding factor in buy them. The noise levels are at a minimum at 1200 rpm and below, even at high rpm the noise is ok compared to any competition.

Cosa vi aspettate? Ventola "insustriale Noctua",montata direttamente sul dissipatore Cpu? Si, l'ho fatto...temp scese di 5/6 gradi,oppure di 15 se ti piace il TURBO FAN.

tried to ran it at max rpm...the noise is there..but tolerable. managed to play with the fan curve and still abel to get superb cooling. anything above 1500 rpm will produce some noticeable noise. but with this fan , you dont need to run at max rpm. anything below 1500rpm is already perfect. link it with my nzxt x73 , and wow...temps nvr reach above 65 degree at max load!
