Topic: Replacing FARS Fan with Case Fan

[Herbaldew]

Is there a guide somewhere that I am missing to swap out my Davis FARS fan with a computer case fan (VP2+ w/ 24 hour FARS)?

Yet another Davis fan has quit and they are now over $100 including shipping.  I was going to try to replace just the motor, but Jameco now has a 1,000 unit miminum order.  Amazon is out of stock of the fan that is just like the Jameco and I'm not sure which other fans are OK to use.

Anyway, I can get a 12v wall wort and run a line from a nearby outlet to my ISS, so was thinking the case fan may be the best option.


Thanks

I highly recommend Cooler Guys. Any 80mm fan will pretty much work with very minor modification to the fan housing.

LOL! You gotta be kidding me?! Tell me everything is fine.  Must be sold at the grocery store.   Unbelievable.

Here's what I use. Overkill, but works in my climate just fine. i'd shoot for the 25-45 CFM range. Don't go lees than stock.
