I am looking for a replacement for an 80mmx x 25mm 12VDC 0.25a 2-wire fan, but I do not know the CFM or RPM of the original, can you advise? The original is a model# 8025S.
DigiKey has 10 possible replacements but I don’t know which way to go.
Thanks!
Welcome to the forum.
Were is the fan used?
In most fan applications RPM does not matter and higher CFM is better.
Thanks for the reply.
The fan is used in a 4-bay 3 1/2 inch hard drive raid box.
Noise is somewhat of a concern., So RPM could be a consideration. But I’m sure that whatever is typically used in that situation would be fine.
Small fans of the type are commonly produced with varying RPM setpoints; the “8025” designation is a physical size reference, and a portion of an extended part number not shown would call out RPM, termination, extra features such as speed control/monitoring, etc.
For a given fan however, power input is approximately a cubic function of rotational speed so some limited inference can be made from current ratings. Finding something that matches physical size and drawing a similar amount of power is likely to land a person at least in the right ballpark, since the laws of physics apply pretty much equally to everybody. In any event, some fan is better than no fan.
Give FAD1-08025CBJW12-A a try, and see this post and those linked from it if you’re interested in understanding more about fan stuffs.
That model looks like the perfect spec. I’ll give it a go! And thanks
for the detailed response.
