Hecaton Posted November 10, 2011 Share Posted November 10, 2011 I'm getting some intermittent but very noticeable coil whine (well - a high pitched whine anyway) from my psu since I built my current system a month or so ago. After lots of tinkering I've managed to isolate that it only occurs when the cpu is below a certain load. Sometimes simply having firefox open is sufficient to silence it and I can keep it at bay by having a game open in the background. 25% cpu use always seems to work. I tried running Prime95 (cpu stress tester) last night and that stopped the whine the instant I ran it. Using 100% cpu for the record. The GPU and PSU both came from my previous system and I never had any issues then so it definitely appears to be a connected to the processor/mobo. I've turned off eist, c1e and epu on the motherboard. I'm forcing vsync on for everything. I tried safe mode and couldn't hear it there. I have the latest drivers for gpu and processor and have updated the bios too. Any thoughts? I don't really want to have to keep my cpu under load for the rest of the machine's life if I can avoid it. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 12, 2011 Corsair Employees Share Posted November 12, 2011 Apply for an rma to have the PSU replaced. Or return it back to the re seller for a replacement. Some of the tx inhibit the coil whine noise. It strictly an audible issue. Link to comment Share on other sites More sharing options...
