loukas77 Posted November 4, 2012 Share Posted November 4, 2012 Hello. This is my first post here. I recently built my new PC (less than 3 weeks ago) and I had the HX650 Gold edition as a PSU. Since it made a squeaking noise that is best described if heard, you can find it . Well, I took back my PSU to the retailer I bought it, and after one week without PC they finally called me back to tell me that it is a common problem with the first shipment of HX650s, so they advised me to either get an HX750 or any other PSU i would like, or a full refund, because if they gave me another HX650 the problem would most likely be there. I decided to go with the HX750, paid the price difference and got it yesterday. After installing it, everything was fine. No more of the squeaking. Now the problem: when the PSU load goes up, the fan starts spinning (normal). However, it does not just spin quietly as anyone would expect from a 25-30% load. It spins at full speed (and noise) for about 3 seconds, and AFTER that it goes down to spin on the (quiet) speed it's supposed to. I want to know if this is how the HX750s behave or if my fan (or the fan controller maybe) is faulty, because the 650 did not spin at 100% and then go down to quiet levels. It was always quiet (except when squeaking). It's not like that the PC drains so much power that the fan needs to spin at 100% speed, because this does not only happens when gaming, it happens and on casual web browsing, if the fan starts spinning. In general, every time the fan needs to start spinning, it starts at 100% and then drops at the right speed. Is this normal? I think not. Should I take my brand new HX750 back to the shop and be one more week PC-less? Sorry for the long post and thank you in advance. P.S.: Minor question: The psu does a slight "clank" sound when the pc is powered off. Is this normal? I consider this normal, as my previous PSU (on my old PC) does the same, it's just that the HX650 did not do it. Link to comment Share on other sites More sharing options...
