Ok..

So I found Tri-Flow at REI in the bicycle section.. Unfortunately, there isn’t an REI very close to my house but they are open to 8pm so I drove out and bought it.

Tri-Flow is pretty cool, it is rated to 475F and the cards will shut the system down at less than half that temp so it seems like a good match. It’s a 4oz Aerosol spray can.. The tube which attaches to the sprayer is too large for the 1/16” hole I drilled (the tube seems to be about 3/32”) and the propellant was way too energetic so I filled a needle oiler and used that to apply the lubricant.





The fans move way more freely than they ever have so I reinstalled them and they are running great (so far at least) with no kick starting required.

I plan to run the fans overnight at 100% and then set them to Automatic tomorrow.
