## Questions & Answers

**Q: Does it have a 3 pin or 4 pin connector?**
A: A PWM fan is supposed to have a 4-pin connector. If you bought one of these fans and it has a 3-pin connector, you didn’t receive the right product.

**Q: Are these the fans used in the Cooler Master H500?**
A: They are not. The fans used in cases are actually case specific, but there are retail versions of the fans that are slightly different. The retail version of the fan in the H500 is the MasterFan Pro 200mm. MF200R.

CM-PNguyen

**Q: How many Amps or Watt?**
A: I am not really sure as I have not measured the current drain - but Cooler Master say the Power Consumption is 3.36 Watt and  Current (Ampere) is 0.16 A (Max 0.28 A)I have a 1050 PSU  and it was not an issue.

**Q: Sorry if a newbie question, but how do the LED lights work, are they part of the connecter that goes to the psu/fan controller, or are they seperate?**
A: Fan has only one wire that goes into motherboard or your fan control unit. LED will feed from that. If you need to disable it you will have to add a switch or cut translucent wires on the dan itself.

### ⭐⭐⭐⭐⭐ Nice Cooler Master Fan
*by L***D on April 21, 2021*

added this fan to my evo 212 black to match the silencio 120 fan it comes with for a push pull configuration, i put this on the front end of the heatsink as the max rpms were higher and put the one that came with the evo 212 black on the back, works great and keeps temps down just a bit more, only prob is since the max rpms are higher with this fan you can really feel and hear this thing rev up when the cpu is under load, it damn near vibrates the case lol even with the rubber absorbers attached, i never cared about noise from a pc build for the most part because everyone is always doing something and making noise in my household so its nothing compared to my kids running around the house, i just found it funny i could feel the case vibrate next to my feet when this fan gets going

### ⭐⭐⭐⭐⭐ The slience....omg!
*by W***. on February 13, 2016*

Wow, these fans are are good as most people say they are. They're extreme quiet yet the static pressure rating is pretty high. With my case currently and the positioning of my Hyper 612 v2 heatsink I'm only able to install one of these fans on it.I did noticed a very minor temperature drop on my CPU during regular use however it's just averaging around 2-3 degrees lower. The biggest improvement, IMO, is the noise as no matter what CPU intensive thing I do the fan speed increase only a tiny bit yet still cools the heatsink properly plus remaining whisper quiet.Get these fans if you want a quieter PC while being able to push air through fins for cpu heatsinks or radiators, but remember it is pricey.FYI,High Static Pressure = How easily fans are able to air through heatsinks or radiators. Does not mean more air flow.High Air Flow = How much air a fan is able to push without being blocked or constricted aka heatsinks or radiators.

### ⭐⭐⭐⭐⭐ quiet
*by N***M on April 6, 2024*

The old fan was still working but getting louder and louder, installed this one in minutes and my computer is back to running at an acceptable volume
