Review: Nice - Brilliant for the price and very low noise easy to fit
Review: Good value for money but nowhere near silent - I bought this 6cm fan to replace the one in my 2005 JVC RX-E5 AV amplifier that had become annoyingly noisy. The original fan was rated at 65mA, so I put an 82 Ohm 1 Watt resistor in series with this AAB fan to drop the current to around the same. This dropped the voltage across the fan to just under 6V and gave almost silent operation* with still adequate airflow. *In this configuration in a quiet room, the fan is just audible with my ear 20 cm away from the amplifier front panel. The "Super Silent" claim is definitely not true as this fan is audible from 5 metres away in a quiet environment when running on 12V, but if you're restricted to having to use this exact fan size and are happy to run at reduced voltage and airflow, this may be the right fan for you.

## Features

- Warning:Not suitable for children under 10 years. For use under adult supervision
- Warning:Only for domestic use
- ✅ EFFICIENT> 3D printer fan with dimensions 40 x 40 x 25 mm, 4500 ± 10% RPM rotational speed and large-8,26 m3 / h for maximum release current computers cooling.

- ✅ ASSEMBLY IN POWER SUPPLY> It is also possible to attach the fan on the power supply. This leads to the low noise level. One should it to the motherboard with 3-Pin - connect - cable (Einaderkabel 30cm). Such a solution is inexpensive and reduces the noise.

## Questions & Answers

**Q: Does the 40mm version have 2 or 3 wires?**
A: AAB Cooling Super Silent Fan 4 has 3 wires.

**Q: what source should i use to connect 2x 200mm to the electricity?**
A: This fan is 12v dc. If you are using it in a computer, then there may be suitable connections on your motherboard. If you are using it "standalone" then a 12v dc power supply, rated 3amp ( for two fans) should be adequate.

**Q: which direction should these be installed?  I'm using them for a printer enclosure and want to pull the heat out, but there is no direction arrow**
A: Plug the motor in, check which way the fan is blowing then mount in the desired direction.

**Q: What are the 3 wires for? Positive, Negative and........?**
A: Normally it is speed (output) of the fan

### ⭐⭐⭐⭐⭐ Very powerful
*by M***M on 17 September 2023*

Really pushes a lot of air for such a small fan, but can get quite loud at 12v , reduce it to 5v obviously it's not spinning as fast, still moved some air so might be better for a smaller project that doesn't need as much cooling
