I have an ART SLA-1 (stereo class AB power amp) and the stock fan is noisy. I want to replace it. I'm not an engineer, but have replaced many noisy fans in computers. Apparently it is a 12v 40mm x 20 mm fan. Should this one work?
Silenx
Here is the original.
Thoughts??
P.S. I just took out the original fan; it's made by Bi-Sonic, and is a DC brushless fan, model SP402012H, operating voltage 12V (10.2 - 13.8), current draw 0.16A; power consumption 1.92w. The Silenx specs are: operating voltage 8-14v; current draw 0.03A; power consumption 0.36w, so that all seems fine. What concerns me is the Bi-Sonic is 7000 RPM with a Flow CFM of 8.53, and the Silenx is 3000RPM with a Flow CFM of 6. I don't drive this amp hard at all, so I don't expect it to ever get that hot; will this "quiet" fan be strong enough??

Should be ok, give it a try. Make sure the connector fits it.
Much of the reason that it's quieter is that it runs slower.

Did you try this in the end? Finding a quiet 1U rack amp these days in impossible. I have an SLA1 and this might be my only hope!
grease
Try oiling or greasing the existing fan
Noise is caused by drying up of lubricant
You may find a rubber plug under the sticker
Remove the plug and put a few drops of thin lub oil...like sewing machine oil
Add about a match head of grease
Close up
Should see less noise
Altermately, put a CPU fan if you can, the larger the fan the lower the speed for the same air flow.
