Hi,
I've a CUV4-X motherboard for that I didn't use for some weeks, I wanted to reinstall it so put it in it's case again last week, after powering it up I noticed it had 'coil whine'. When I remove the videocard the noise is gone, tried 2 videocards same results. I've used the board for years and this is the first time it has this annoying sound. I tried two PSU's but same results, I'm 100% sure it's coming from the motherboard just not sure which location.
Here is a picture of the motherboard http://hw-museum.cz/mb/46/asus-cuv4x
Take a look at the first picture, bottom right (near the memory slots) - I noticed that coil (or choke or inductor don't know how to call it) is VERY hot to the touch (like I can touch it for 2 seconds then my finger 'burns'), other ones are cool. This is after 10 seconds after powering the PC on and sitting in BIOS. Is this normal? I have no idea if it was always so hot to the touch, might have something to do with the high pitched sound? Anyway I never replaced any caps on the board, but they all look OK, the ones near that hot coil do feel kind of warm to the touch though, probably because that coil is heating them up.
Any thoughts?
