RPC overheating.
Peter Campbell-Banks
CD-RW.
Several weeks ago I found that it was freezing after a couple of hours
use.
Last week I removed the lid and the machine has been running
continuously and the PSU fan is working OK, so I assume that
overheating is the problem.
I am going to fit another fan, the question is do I cut a hole
somewhere in the case/lid or not.
I would appreciate any useful suggestions.

yes, but is the airpath clear?

check the air path.

This is what I was thinking of doing, but I thought I would check that
it is OK to cut a hole in the lid.
Of course, having a 2 slice machine, there is plenty of clearance.
I have a selection of hole-saws and will find one to match the fan
size.
Thanks Charles, Stuart and Mark for your prompt replies.

Mine is also a two slice - and packed full. But don't have that problem.
Are you sure it's not dust blocking the various grills on the sides and
back? Other thing is not to have an HD in the place on the base - it will
tend to run very hot there. I have one mounted at the back of the top
slice. But you need to fabricate brackets for this - I used ally angle
bought from B&Q. The other occupies the bay above the floppy.

That includes inside the power supply. Open it up and blast all the
dust out of it with a vacuum cleaner on 'blow'.

You mean blast more dust in to it from the vacuum. A can of compressed
air will avoid this problem, and is far less likely to damage
anything.

No. I have to take the dust bag off in order to connect the hose to
the high pressure side but I do blow the dust out of the hose first.

Maybe, but if you saw my PSU when I opened it up you'd realise that a
can of compressed air wouldn't do very much. In fact I sucked most of
the dust out before blowing out the last bit.

If you have extra hard drives or CD drives installed, make sure that the
ribbob cables don't interfere with the air flow from the power supply fan.
With an IDE card in a podule slot, it's very easy for the ribbons to
completely block any flow across the inside of the case.

You can replace the ribbons with round-section cables which are far
less likely yo obstruct the air-flow.
