These computer fans vary widely in air moved for noise made and current consumed. The one above is a winner in all three and has a 6 year warranty.
I have a Nicro solar powered vent. Many years ago I cut the wire to the fan motor, removed the battery and the impeller, and covered the solar panel. It now has computer muffin fans pushing about 20x more air through it.
Before this Nicro vent became Noisy, the "c" sized Nicad battery would last for about 2 days in the shade, running all night too.
One can of course spend much less, or even salvage one from an old computer. but it might very well consume 3x the current, make twice the noise and move no more air.
