Agilent 34410A Noisy fan
(1/6) > >>
jstarr:
I just bought this from Ebay and it works beautifully but the fan is noisy and the speed (by its sound) appear somewhat irregular.  Oddly, if I put one of my fingers partly over the intake (about 1/4 of the intake) the fan speed and sound becomes quiet and regular.  Any suggestions or should this be my first Tear Down !!

Bearings?
LA7SJA:
The 34410-68502 (replaced bye 34410-68503) Assembly-Fan should be replaced.

I have installed low noise Papst fans in almost all my instruments that made too much noise.
Papst makes them with internal thermistors on a little cable and you can place this sensor on the most heated part of the
instrument (heatsink) and the airflow will increase when needed. I have been doing this for years and never had any heat
problems with any Agilent instruments
