I have replaced the noisy fan of my HP53181A with the following:  Sunon A40201V4 (Super Silence Series  :))
http://www.digikey.com/product-search/en?mpart=HA40201V4-000U-999&vendor=259

The fan is very quiet by itself  (12.8dB-A), but when installed, due to airflow & high rotation speed, it is still noticeable in a quiet environment.

Found this Fan with comparable specs on ebay.de

That fan should work well. If it is still too loud, just add a series resistor in the cable. The instrument does not need much cooling, just a small constant airflow.

I just bought a HP 53132a with the second channel BNC connector smashed.   Does anyone know where I can find a replacement BNC connector?  I looked on ebay and could not find anything.

Other than that, the unit is perfectly working.  I also added the oven crystal to the unit and that is also working great.

EDIT - I have found a better connector that is confirmed to work - TE Connectivity AMP Connector 5227677-1

To me it looks like an Amp 5413879-1 - or pretty close to that. You might want to consider just stealing one of the connectors from the back panel(whichever one you'll use the least).
Dwaine:
That's a good idea to use one from the back.   I'll keep looking for a good match BNC connector.  If I find one, then I'll post the details.
