Negative Positive
Title: You don't know what you are getting.
Review: At this writing date, the listed manufacturer on the Amazon page for this fan is "Alpha and Omega Computer," which is a wholesaler of fans. Their website lists the manufacturers of their 60 mm x 25mm ball-bearing fans as Sanyo, Evercool, and Sunon. These are all decent fan brands, and they have a range of specs for airflow (cfm), speed, and noise. However, the Amazon page for this fan currently lists no brand or specs, so you won't know which fan you will get. I received a 24 cfm Sunon fan with 34 dbA, which is quite loud for a small fan, and is the loudest fan that Alpha and Omega carry for this approximate cfm. For example, there is Sanyo fan with a higher cfm at 28 dbA, which is significantly quieter. So if noise matters to you, I'd buy a fan with the manufacturer and specs listed, otherwise you may find the noise very annoying.
Is the review positive or negative?
