Generally, yes, but cooling fans are often designed to
operate at higher temps. That point notwithstanding, the
temps in your hood aren't all that significant for a fan.
If your hood is over 150 degrees without a fan, the temp
will be less than 150 with one, blowing or sucking. If you
hood is over 150 degrees, an fan might not help, you might
need a fire extringuisher--what the heck have you got
burning in there? ;-)
