| 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 !! john |

The 34410-68502 (replaced bye 34410-68503) Assembly-Fan should be replaced. http://www.home.agilent.com/myagilent/faces/partDetail.jspx?partNumber=34410-68503&imageStatus=YES JFG |

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 |
