Not only that, it’s also cheaper and comes with an IEC power cable and socket, making it easier to switch to longer cables if required. The most popular model in the range just got even better!

Please note: though digital fan speed controllers (like this one) are a very cost-effective solution, they may generate a humming sound. This is an unavoidable consequence of using pulse width modulation to regulate fan output. We highly recommend SMSCom Hybrid Fan Speed Controllers, which instead use heavyweight transformers and run completely silent.
