Hi,
less than 2 years ago the small (80 x 80 x 15 mm) fan on my Ultra 80's
DC-DC converter started playing up - making a lot of noise. I was never
able to find a *decent* replacement of the right size. 15 mm is very
thin, so the choice was severely restricted, despite me using catalogues
from lots of professional electronic suppliers. A 20 mm fan will not
fit, so I replaced it with a poor quality Sunon (not Sun) fan which I
bought from RS in the UK.

Sun don't sell a replacement fan as far as I can see, and I don't wish
to buy a new DC-DC converter just to replace a fan.

The fan has a hard time where it is. It is in the hot air stream, which
is not good for fans. The only one I could find had sleeve bearings,
which like the heat less than ball bearing fans. A ball bearing fan
would have half a chance in that position.

As you can guess, the fan has started to die again, less than 2 years
after replacing it.

Does anyone know of a source of these. Ideally I'd like

Decent quality, ball bearings
1) 12 V
2) 80 x 80 x 15 mm
3) Available to the UK.

The Ultra 80 is a well made machine, but the idiot who designed the bit
around the DC-DC converter wants shooting. The fan is very poorly
located being in the hot air stream, and being such an odd size it was
hard to find a replacement. I have not started looking for one today,
but judging by my experiences 2 years ago, finding one is not going to
be easy.

Anyone else had problems with that fan?
