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 G.A.S Enviro Controller V2, which instead use heavyweight transformers and run completely silent.
