I have a Escort 2000 Peavey P A System. The fan is making a noise when I switch it on, but as soon as it ''heats up'', the noise stops. Is it because of the cold weather or is the fan giving notice?

It might be giving notice, it might have some loose screws, but then again, it might just need some oiling.

There's probably a sticker on the rear side of the fan (where the power wires come out), remove it, underneath you'll see an aluminium cover near the center. Take this cover off with a pointed knife or similar, it should come off with just a slight force and you should now see the axis fixed in place by a clamp.

You just need to put a drop or so of oil, just make sure it reaches underneath the clamp into the bearing/bushing and if the bearing/bushing was just a bit dry or dirty and if it's not really damaged then the fan shoud now run quietly.

Put the aluminium cover and the sticker back in place, try it out, if it's silent, you win, if it's still giving notice then it should most probably be replaced.
