Agilent 34410A Noisy fan
<< < (6/6)
Odd:
After ordering and receiving a 35x35x10 Sunon, I discovered that mine too had the NMB-MAT 12v 0.1A fan  (30x30x10mm).
The fan supply is not properly regulated and was something like 13.2v with the fan connected.
I added a 330ohm resistor in series, which made it work nice and quiet at about 6 volts or so.

HighVoltage:
Nice that you confirmed the 35x35x10 mm

I just opened one of my 34410A and looked at the fan that I had installed many years ago with a 100 Ohm series resistor.
Here are some pictures

 
Odd:
!! no no no !!
I did order, and received the 35x35x10 fan - but mine was a 30x30x10 !  (as somebody posted earlier.)
Yours has a duct that reduces the 35x35 screw distance to the size of 30x30.
