Surprising result from 14" ebay electric fan

Damn, that's a pretty good temperature drop. How much current does it pull, are you running it through a relay? 65'

No relay, it pulls 7-ish amps maybe 10. The thermostat is rated for 16a at 250v ac so I should be okay I think.

My experience with the direct to rad core mounts is they can wear through the tubes I would make a couple straps to mount the fan to that attach to the outside of the rad core frame

This is my concern as well. I would like to mount a flat plate as a shroud and have it pull across the entire rad. I just have to be less lazy than I am today. Much appreciated comments guys
