noisy nforce2 fanless motherboard
Posted: Wed Apr 06, 2005 7:16 am
hi,
i'm trying to progressively silence everything in my pc but seem to have a noisy motherboard. I was always under the impression that motherboards were inherently silent components but this one is definately making a noise.
my setup:
gigabyte ga7n400pro with chipset fan removed
athlon xp 3200, cooled by a tt silentboost with fan @ 7v
maxtor 200g diamond plus 9 pata hdd
antec phantom fanless psu
radeon 9600 fanless
only fan in the case is the cpu fan - i'm probably going to go in the reserator direction once zalman sort out their pump issues.
Anyway, I've read this thread but it doesn't really answer my question as in that case hdd+vga was the culprit.
what i've ruled out:
-definately not the cpu fan - if i stop it with my finger, noise continues unabated
-definately not the psu - i've read some comments about the antec phantom having a slight buzzing noise and i can hear that ever so slightly if i press my ear against it but its definately not the current noise source as the psu is removed and away from the case
-definately not the hdd, again its been removed fromthe case and resting on foam. if i press my ear against it i can hear it woosh and seek but its a different noise and the mystery noise is louder than the hdd defragging.
this thread suggests its due to dodgy esr caps, but most of the ones on the board are sanyos which from what i've read are pretty good. I eyeballed them all and theres no bulging or smelly ones.
here (the comment by seed) they suggest its when the pc is under load but i get it at idle as well. Now if i boot up the pc with the hdd disconnected it doesn't happen, but when its in as soon as windows starts to load it starts and then never stops - but its definately not the hdd as the noise definately comes from within the case, even when the hdd is isolated away from the case
it definately is emenating from the area around the cpu but its 100% not the fan. i was brave/stupid and gently pressed on all the caps + inductor coil thingies with a plastic rod and the noise continued unchaged.
have i got something bizarre happening, or is it normal for nforce2 boards to be noisey?
thanks
mike
