Case fan at -10c - any experience?

[orion456]

I want to run a case fan at -10c. I know most of them have fluid bearings and so will freeze up after a while. Any one know of a fan that just uses air and so will run at -10c?

Wondering if a maglev fan would run at -10c. Its bearing is frictionless and uses no fluids, just magnetic levitation.

Just out of curiosity what is this for?

I looked up a bunch of datasheets for reg ball bearing fans and they all have the min operating temp set at -10C. You should be fine.

There is no temp listed in the maglev sheets that I can find though. http://www.sunon.com/uFiles/file/03...d/Sunon DC Brushless Fan & Blower_(190-E).pdf

Would have thought the grease would freeze up on ball bearing fans at -10c. Thanks for the info.

The fans in my car also have no issues at -10C.

Rarely do we hear about concerns of being too "cold" in this hobby. A fun read!

Canadian? Natural sub-zero cooling?

I'm actually cooling a telescope mirror from room temperature down to -10 or so.

I will try 3 fans out and see which one works best. I now have a maglev 120mm, a enlobal bearing 120mm and a tricool air bearing fan. I'm going to leave them outside over night and then see which one starts up. I believe its going down to -20 tonight.

Any fan will run at -10C or any temp as long as the fan doesn't melt ( over 100C) and rifle bearing fans sharft fans are not good if it is ball bearing fan then it will run under -200C L2N TEMP and can run at 69C max before the plastic melts
