I have my IBM 5161 expansion unit next to my 5160 but I don't use it as much as I'd like because the PSU fan is orders of magnitude louder than the 5160 PSU fan. (And it definitely is the fan, as I have both MFM hard drives in the 5161 unplugged.) I understand these fans are not simple replacements with typical modern case fans -- am I right they are AC fans, 220V? Are there modern quiet equivalents? Is the size standard? Or, is there a way to service the existing fan so it isn't so loud? (It's just a loud operating sound... it's not squealing or vibrating or anything)
I searched the forum for previous discussions, but most of them are about soldering to a 12v line and using a fan with much higher CFM. I don't want a higher CFM, I want a quieter fan so I can power it up every time I want to sit down and program for a couple of hours. (It has my EMS and MDA boards, and hosts a monochrome monitor, so it's how I develop graphical stuff with the program on the color monitor and the debugger on the monochrome monitor.) Any pointers for 2018/2019 appreciated, thanks.
