Sigma Poker Machine Fan

[rgull77]

Hi, I am replacing the fan on my Sigma poker machine. I believe I have found a replacement ( size, volts and amps), however the existing fan has only red and black wires and the replacement has red, black and a white wire. I can only attach two to the plug, now you must understand that I make ZERO assumptions when it comes to anything that has to do with these machines. So that being said.... which wires go to the plug?  Or, if there is a differently wired fan I should know about, I'm all ears!

Thanks you in advance,
Randy

You probably purchased a fan with a feedback wire for systems that read the RPM back to a controller. In most instances the fan will run fine with just the red and black wire.
You could probably spray the original one with a ton of electronics cleaner and get it to loosen up but its a messy task, especially if you found a replacement.
If I recall those have noisy fans.

Thanks Chris
I haven't bought it yet. It wasn't easy to find one with the same specs and same size, and there were none with just two wires. If this will work then I'm going to get it. I don't want to mess with the old one, it was making a very loud noise!

Watch a YouTube video on how to remove the fan blades. You can clean the bearings if the blade comes off.
But yes,most important is the voltage of the fan, amps isn’t critical but will keep the airflow rating close to the original.

What size is that fan in milimeters?
Outside to outside and total thickness.
Can't be too hard to find?

The fan is 90mm by 25mm. It wasn't that hard to find I guess, just so many sizes out there.

To close the topic, this is the fan I settled on. Went with two wire fan. I installed it today, it's very quiet.
