Pros: Silent.Very silent.Minimum vibration.
Cons: Lower CFM than rated on box.
Got these as i was looking for cheap 120mm fans.
Intended to buy just on but ended up buying this 4pack.
As the title reads,you get what you pay for.
The plastic doesnt look cheap but it aint fancy either.
Simple matt black,easily scratched low grade plastic here,probably this is what makes it so light.120grams per fan.
Its a 7 blade fan with no fins so dont expect much.
Specs on the box are
Dimensions are 120x120x25mm.
Voltage : 12v DC
Current : 0.15A +/-10%
Power input : 1.8Watt +/-10%
R.P.M. : 1200 +/-10%
Airflow(CFM) : 44.73CFM
Air Pressure : 1.65mmH2O
Noise : 19.1 dB.A
Bearing : Sleeve
Life : 30,000Hours
Cable length : 300mm.
Off these,the noise rating is real as i barely hear these fans.
The CFM is not true as I have a 55cfm scythe which displaces almost twice the amount of air as compared to this fan(no testing done,just placed my hands in front of both the fans at the same time.),both fans running at 12V from PSU.
U get a 3 pin plug running with a cable which is 30cm long,which is enough if u have a mid tower case.
Life time is rated at 30,000hours.That is more than the time most of the users use a set of fans.
If u are running a lab,internet cafe,etc. where you have a lot of computers or you are just the average user,this is a good option.cheap and long lasting.
Performance enthusiasts,gamers,folders,etc. who use air cooling,you might want to go for a better fan.At this CFM,you wont be moving enough air to cool the heat produced by your system.
Not good for radiators and heatsinks as static pressure isnt good.
At most can be used an intake/exhaust fan for those on stock clocks.
