Does anyone know a good source for replacement fans for the Cisco 2950-T-24?
A "silent" version would be preferred. The fan is 40x20mm and has a 3-pin connector. Yes, I've already checked Digitec but they don't seem to have anything that matches.
tried distrelec? they have plenty of papst fans which usually are very quiet. perhaps this one will work, even though it's flatter than the one you're looking for?

Normaly, i search the datasheet for the original fan (NMC ?) and look for an equivalent (equal or less Wattage, equal voltage, less dB, equal ore more presure and airflow) at http://www.ebmpapst.com Their express-service for me is

For the ancient 35??-XL-AN Series, we used Papst 405 (40x40x20, 5V, 10m**3 18dB(A) (but that ws without tacho, but i strongly believe there is a verison with tacho available, also 12 V Versions...
and they have many of the Papst-fans on stock and deliver fast.
If not found there, you may try farnell .
As a last chance you may try sunon fans, found for example at reichelt.de , better some airflow than nothing; but their usage-period is much shorter.
Hope this was not to much werbung/advertising,
