it's amazing how many models of fan produces the SANYO DENKI  :-+!

Actually for 60x25mm fan, its "relatively" easy to find compared to others weirdo non standard sized fans.

About Sanyo Denki, look for something similar like these below (photo of my 60x25 nos fans), trust me, these are very high quality made fan. Have been using them for almost decades and many of them are still running well today at 24x7 for more than 10 years.  :o

Suggesting to stop using that Noctua, your scope's components life may be shortened significantly because of higher temperature inside.

It depends on what use is made of an instrument.
I am a hobbyist, I turn on the oscilloscope occasionally.
I'd be curious to monitor the temperature with the old fan and the noctua to make a real comparison of the temperature difference.
The fan speed is variable, there is an internal controller who is dealing with.
I think that the internal temperature is the same, perhaps the controller will increase the speed of Noctua than the original.
The problem may occur in summer, when the outdoor temperature was too high.
In my lab will not be a problem, the temperature is constant at 20 ° celsius ....

BravoV:
Suit your self, its your scope, just a suggestion.  ;)

Your logic is flaw there, at high temp the controller will try to crank up the fan to max speed, still its only 1/3 of the original one at "full speed" which may not be enough.

Anyway, just forget about it, no big deal, by that time maybe you bored to death with it, and probably upgrade to new one.  >:D

Carrington:
I have plans to do exactly the same (using the same replacement) with my DS2072, I haven't done yet because it's in warranty. As it is winter here and the fan speed is regulated by temperature, now does not sound much. So, for now I will not touch it.

AndersAnd:
Do you have a close-up picture of the label on the original fan? It's hard to tell what it says in the picture above.
