Hello everybody,

recently I bought an old Powermac 9500/200. It's alot of fun to play with it and it's worth every Euro I paid for it. This Mac has a nice feature - its video card comes in PCI flavor and has a VGA connector, so it's possible to change the original monitor which could be used as a killing weapon if dropped from a window, to a nice flat screen LCD.

This Powermac has unfortunately one limitation. It's loud like a vacuum cleaner. Is there a possibility to make it less loud? Is it possible to clean/oil it's fans, so they remain silent? If yes - which elements must get cleaned? Or maybe some parts should be exchanged?

Thanks in advance for your advice.

In my experience it's a past-it's-best hard disk that can cause most noise.

Disconnect the power supply to the hard disk(s) and start up to see if it makes much difference.

Sometimes extra fans are added - I had one attached to the side of an HD in an 8500, which I disconnected without issue.

My 9500 is not the quietest machine ever, but it should be acceptable sitting next to it.

the sound/noise of the HDD can be distinguished, it is very unique and I don't mind it. The nuisance must be a kind of fan which turns consistently. I suspect the power unit with old fan...

My 8600 and 8200 are both pretty quiet. Not iMac or even Mac Pro quiet, but they're not really loud either. Most PCs seem to be louder than either of them.

I find the 800-840av-8100-8500-9500 form factor machines to be blissfully quiet as a rule, so there must be a fan or a drive needing replaced or minimally oiled.

There are actually two fans in a 9500: the PS fan and an additional fan in the area of the CPU daughter/ PCI cards.

I just picked up a 9500/132 and it's fairly loud. I'm thinking of replacing the PSU fan and second fan with modern, quiet versions. Has anyone done this?

If not, I'll go ahead and do it and report back.
