¿Is working the fan of the cic navy?

[pitoncho]

Hello everybody!

Arround a few weeks i tried to retrofit a cic navy bussines in my 87 pre, at now here in Spain it is too hot and the cic navy is too hot. I tried to dissasembly it and i tried to plug in without all the metal because i want to know if the fan was working.

When i tried it, i saw that the fan didnt work, soo, i need to replace the fan, i know that the original could be very expensive, and i want to buy some similar in aliexpress where i see a lot of them that are similar. Anyone knows what size can i buy a new fan?

Thank you!
