Technical data Review: replacement fans - Am using one of these in a solar powered water heater/diverter which diverts unused solar powers excess kws generated into the immersion heater which gives lots of free hotwater, the achilles heel of the diverter is the cooling solution, a cheep fan which jams repeatedly, wd40 worked for awhile but eventually it siezed, this fan was easy to fit and provides more cooling plus quieter, have spares should it fail? cool....

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ replacement fans *by S***F on 1 December 2023* Am using one of these in a solar powered water heater/diverter which diverts unused solar powers excess kws generated into the immersion heater which gives lots of free hotwater, the achilles heel of the diverter is the cooling solution, a cheep fan which jams repeatedly, wd40 worked for awhile but eventually it siezed, this fan was easy to fit and provides more cooling plus quieter, have spares should it fail? cool.... ### ⭐⭐⭐⭐⭐ silence is golden *by D***F on 19 September 2024* super quiet - in fact almost inaudible ### ⭐⭐⭐⭐ Good value for money but nowhere near silent *by J***T on 10 April 2019* 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. ## Frequently Bought Together - AABCOOLING Super Silent Fan 4 - Silent and Efficient 40mm Fan with 4 Anti-vibration Pads, 12V Fan, PC Cooling, 3D Printer Fan, 4cm Fan 17.9 dB(A), 4.9 CFM, 4500 RPM - Noctua NF-A4x10 FLX, Premium Quiet Fan, 3-Pin (40x10mm, Brown) - Noctua NF-A6x25 FLX, Premium Quiet Fan, 3-Pin (60mm, Brown) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/50811864-super-silent-4cm-40mm-fan-12v-pc-and-3d-printer](https://www.desertcart.sk/products/50811864-super-silent-4cm-40mm-fan-12v-pc-and-3d-printer) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-06-18*
