"un-original" fans not working

[magnusrm 0]

Hi.

I had a crash with the Ultimaker 2, which ruined both the fans. I ordered a set of fans from eBay since the support took so long to reply to my mail.

The fans were 30 x 30 x 10mm 12v 0,08A, the same as the ones that came with the Ultimaker 2:

Ive tried to connect them, but they dont start (I have made sure the fan speed is at 100%, and testet different speeds).

I have also measured the voltage to be about 19 V, but still no movement.

I dont have any power source that I could test the fans with at the moment.

I also may add that the original fan wires that runs along side the feed tube is absolutely garbage. Thin as a hair.

Have anyone else encountered problems with un-original fans?

Has nobody tried to use aftermarket fans with their UM2?
