“I have purchased from “Quiet PC” before and had no doubts in using them again. I phoned up one of the engineers as I wasn’t going to use this “quiet fan” for a pc. I needed one to keep my amplifier for my radio transmit ions, which in its self had to be an extremely quiet running fan so that the fan noise wasn’t transmitted with my voice. The engineer suggested a few options that were possibly be better for me and my purpose and I have to say he was smack on. The fan I bought is incredibly quiet to the point that I had to hold it up close to my ear to actually hear it running. Perfect for my audio transmit ion purposes. This model even comes with multiple adaptors/cables and a power reducer to drop the input voltage if required, and extension power cord, and various adoptions. I couldn’t be happier. Brilliant service and very quickly posted well packaged too. Thank you.”
