panpap Posted February 25, 2013 Share Posted February 25, 2013 Hi there, I recently built my new PC (almost a month ago) and I had the HX650 Gold edition as a PSU but it was making the chirping sound, the store replaced it with another one that was faulty too, so i decided to pay the differece in price and bought the HX750 gold edition. Now there is no chirping sound from the power supply but in medium load the fan in the PSU does not go from 0% to like 40% or so, it goes straight to 100% for about 05- 10 seconds and then shuts off. It looks like fan controller is faulty. the quote describes my problem exactly. Thank you very much Ram Guy, I really value your help and I hope that you pass our thoughts. What we are talking about here is not fan noise on "nearly full load". We are talking about noise when the fan starts spinning. As you said to me this is when 40% load occurs (though on the box it says 20%). However, the fan does not start spinning quietly. That's what disturbs us (and, I say again, the HX650 did not behave that way, the fan was always quiet). Yes, the PSU is COMPLETELY silent at low loads (great). Yes, the PSU is VERY silent at high gaming-stressing loads (amazing). It is noisy at the time between those 2 phases (bad). I want to know if this problem is solved and if it is, should i take it back for the fourth time for a replacement or make an RMA request? thanks in advance Link to comment Share on other sites More sharing options...
