Agilent 34410A Noisy fan
David Hess:
I try to avoid silicon oil because it tends to creep.
For fans bearing my current favorite oil is heavy gear oil like you would use in a transmission or differential. Over the past couple years, the worn fan bearings I have used it on have more than doubled their operating life without incident and are still going.

I keep a couple of small clearly labeled plastic dispensing bottles with needle tips for things like contact cleaner and lubricant (MG Chemicals 801B), gear oil, light machine oil (LPS 2 or similar), flux (Kester 1544), Copper Nu, etc.
SeanB:
Lubricants I keep at work are vacuum pump oil, 3 different refrigerant oils, 2 different compressor oils, 2 different gearbox oils and then greases, one synthetic food grade and 2 different greases. A small amount of moly grease as well along with tacky wheel bearing grease for odd uses. They are pretty useful, though I do tend to buy them in 20l drums.
Odd:
Fan in a multimeter? ( 34410A ) - that's a first ... what's the crazy reason for such requirement?
also: can anyone suggest a suitable, silent, replacement specifications?
HighVoltage:
Just install a Papst SUNON fan of the same size and add a 100 Ohm series resistor in the supply cable to slow the fan down a little. I have done this on every 34410A that I have / had.
Odd:
can you please tell me the papst fan model you have used for 34410A ? (I'd like to avoid disassembly just to figure out the dimensions and voltage & wattage/current)
