My PSU fan stopped working probably a few months ago as I think it ran without fan for a while, an extra fan in the case made this possible without overheating. When I finally got round to changing the PSU this week, I first found out the new one had only 4 molex connectors and I needed 5, any way I managed to connect everything thanks to an extra connector on one of the unused connections in the case, I wasn't sure of what I was doing but all my devices work . Problem is Winbond Hardware Doctor, a monitoring software flashes an alert with the message that the "-5 V voltage exceeds the limit". Apparently it should be negative 4.5 max and it is positive at 3.5 !! I have no idea what this means despite asking around and looking up google. Been running the PC for 2 days like this but certainly something must be wrong and could cause problems. Any help ?
