Question: What is the height of this fan?
Document: I have my computer on a shelf which has limited height and tends to trap heat. By placing this fan behind it, air is forced around the processor and helps remove excessive heat thus extending the life or the processor.
Great desk fan
If you're looking for a fan, get a Soleus!
i would give the fan 4 stars.
Great desk fan! very sturdy.. Love it
They should call this the &#34;hot flash&#34; fan!
I have recommended this fan to 3 of my co-workers.
This fan has no air output. It's going back. You'd have to have this directly up against you to feel air.
The fan is small and quiet. It does not vibrate on my desk, and it blows a lot of air.
Fan would just what I expected work well nice and quiet.
Answer: It stands about 6.5 inches high with the stand, and is a smidge over six inches wide.  When they say 4' fan, they mean the blades.
