| Keysight 34461A Fan Noise |
| << < (3/11) > >> |
| LaurentR:
I have had 3 of the 3446XA and they all had the same, not particularly loud but certainly annoying high-pitch whine. Between the fact that it's tolerable and the difficulty to predict the effects of a reduces airflow on the calibration, this is one of the few pieces of test equipment I haven't refanned. Unfortunately, this means that mine are off most of the time because I don't tend to leave them running when I don't really need them because of the whine. I wish Keysight had picked a less whiny fan. The airflow is not all that high so there should be plenty of quieter fans with similar airflow. |

Has no one tried to locate a generic, quieter replacement? --- End quote --- I ended up putting one of these in mine: https://www.amazon.ca/gp/product/B00NEMGCIA/ |

Make this change at your own risk. Technically it probably should be re-calibrated, but I did not have an issue. |

Is anyone of the voltnuts around here prepared to try exactly this fan with measurements before and after? :popcorn: Even so, I would very much prefer an endorsement of exactly this fan by Keysight themselves. Probably never going to happen. I myself do not have any voltage or resistance references precise enough for checking this DMM. :palm: |
