Yes, I have replaced the fans in four 5370A and 5370B counters with modern 12V brushless DC motor units connected to the 10V supply. VERY nice and quiet. I did before and after thermocouple tests in the chassis. The temperatures were basically unchanged (+/- 3C). Variances could easily have been due to the probes shifting.
I have also done several dozen HP16500 logic analyzers and Tektronix TM5003 and TM5006 mainfarmes. On the TM5003 and TM5006, I run the fan on 8V. They are almost dead silent. Use the lowest current fan that you can find... they tend to be the quietest. _________________________________________________________________ Hotmail® has ever-growing storage!
