“I had bought a second hand Profession CCTV DVR and the normal fan was very noisy so I googled PC & DVR fans and found this company “Quiet PC” and after I read the info decided that this is the one for me, So I bought and when the fan was delivered I set about removing the old fan and fitted the new one and Hey Presto, I could not believe how quite the new fan was and it has now made the DVR more easy to live with in my living room, I would strongly recommend Quiet PC to everyone who has a similar noisy fan problem not only in the fan itself but the service and Communications and fast delivery made this buy enjoyable and very easy to complete, Well done Quiet PC for all your help and service from start to the finish, Best regards Neville”
