Hello The Net:
Mike, thanks for the 53132A fan info.
I also have a noisy fan. I have considered adding a proportional fan
controller since more colling is needed
if aditional options are added, like a more stable internal reference or
a prescalar to 3 GHz or 12 GHz.
Less cooling is needed if no internal options are included. Less cooling
can mean a slower fan speed and lower acoustic noise.
Anyone have any thoughts on exactly where to put a temperature sensor
for a proportional fan controller?
The W1GHZ.ORG website had a fan controller.
Anyone have any thoughts on how to increase the intensity of the dim
display ? Is it a power supply issue ?
I use my 53132A with TimeLab to measure the performance of different
oscillators.

I replaced one last year.
I used a Delta EFB4012HD from Digi-Key but it isn't in stock currently.
I just looked up the specs on the fan I removed and matched it to
the fans available. There were multiple suitable substitutes.

Hi,
My 53132A cooling fan is becoming extremely noisy so I have to fix it
or find ear plugs fast.
If anybody as encountered the same problem witch I suppose is common
I will be interested if there is replacement part easily available
for that purpose.
Regards
Loïc
