Palfrey Posted February 4, 2013 Share Posted February 4, 2013 I recently bought a TX750M power supply, all seemed fine and dandy. Anyway, I put everything together, and it all worked fine, and I've left it on for a few days. However today I noticed that there was a quiet clicking noise coming from the computer, which was audible when the case was shut and the fans were on low. After some investigation I determined it was the PSU fan trying to spin up. I looked at the back of the box, and it does say that it will only spin up if the system load (Watts) goes above 225W. However what I saw online pointed to the fan spinning up on boot of the computer. To test that I restarted the computer multiple times, and it wouldn't spin up at all. I ran Prime95 for two hours or so the other day, and there were no noises then, and the PSU itself doesn't feel particularly hot to the touch after running Prime95 for half an hour. (Not much time I know, but I thought I'd write this and go to sleep.) I'm not currently using a GPU, and only one HDD and SSD. CPU is an i5-3570k, cooled by a PhAntecs PH-TC14PE. Case is a Silverstone Raven RV02-E, with three 180mm fans at the bottom, and one 120mm fan at the top. Motherboard is the Asus P8Z77-V Pro, with one 8GB stick of Corsair low profile Vengeance RAM. Could it just be because the system isn't drawing more than 225W? But that wouldn't explain why the fan doesn't spin up on boot, seeing as that's what other people have said. Have I got a faulty unit, or am I being paranoid? UPDATE: The fan definitely spins, the unit itself isn't hot, and the computer has been on all night downloading steam games. However when it does spin it only spins for a second, and then stops, and the noise is definitely caused by the fan trying to start and stop in the same second. Oh, and why does it keep correcting (sans hyphons) P-h-a-n-t-e-k-s to PhAntecs? Link to comment Share on other sites More sharing options...
