SE fan replacements

[bbraun]

I've got an SE with a really noisy fan I'd like to replace. Unfortunately, the SE uses an odd paddlewheel style fan instead of the fans you typically find in systems since that time. Does anyone know an equivalent part, a conversion to a modern fan system, or another solution?

It is approx. 70mm tall with a power lead running nearly the length of the analog board. From your post it seems as though this is a standard fan type which is readily available, although I am not familiar with distributors of suitable replacement fans. Could you enlighten me?

Here are some pictures:

That's called a squirrel cage fan. It's more common in industrial and automotive applications, and, as you have surmised, is not a common or readily available computer part.

It may be best to see if you can find somewhere to mount a standard computer fan and find one to suit.

Jameco, mouser, digikey would probably have them

Larry Pina has a very clear procedure for doing this in his book Mac Classic & SE Repair and Upgrade Secrets. It was a very common upgrade at the time. Books can be found readily and inexpensively on Amazon.com and other used book sites.

Thanks! I'll grab a copy and take a look.
