Pros: I bought 2 and they are near silent and I have not had a problem with either. They are very inexpensive.

Cons: I don't have a gauge to measure airflow but it's not lots. You get what you pay for I guess.

Other Thoughts: I took of an egg because I expected better airflow. I'll wouldn't use these again myself but for someone who only needs low airflow and wants quiet at a great price these should be okay.

Pros: 5 eggs are for value. The fans work just fine in htpc.

Cons: Feel is, well, as the price suggests. Very light.

Other Thoughts: I don't hear them running but my ears are old!

Pros: -Cheap
-Interesting translucent plastic

Cons: Fan blade splits in half due to oversized fan magnet ring.
Fan magnet ring slowly shifts away from optimum position for max RPM.
Difficult to fasten screws due to undersized screw holes.

Other Thoughts: Not sure if this model had structural flaws in the past but it seems that the batch from which I bought had severe problems.
Manufacturer needs to QC plastic molding and improve their poorly designed fans.
We were sold fans that were prone to high failure.

Pros: - Light

-Easy to Use

Cons: None

Other Thoughts: Very cheap, light and easy to use. Would buy again.

Pros: Nice blue color. Spins around and around. Low Price.

Cons: Doesn't seem to move much air. Its more for looks than cooling ability. No LED Lights in this model.

Other Thoughts: Its a fan and spins around.

Pros: Fan that works

Cons: not free

Other Thoughts: It works, dont know why people expect 25 cfm to blow tons of air, but I got it for a temp solution to a video card fan while I wait on a new fan from the company.

Pros: So far it works as it should. It's Quiet.

Cons: None.

Pros: cooling fan it does what its supposed to

Cons: cheap

Other Thoughts: Good little fan, dose the job for me just fine

Pros: None

Cons: I expel air with more force than this thing.

Pros: + Nearly Silent, which says something for a fan smaller than 120mm
+ Has airflow arrows. You'd be surprised how annoying fans can be in this respect.

Cons: - Moderately low airflow for the size. You can barely feel it to touch but when you place a piece of paper it's a decent flow.

- Only molex connections. No airflow control but that's to be expected at this price.

Other Thoughts: 80mm fans by their nature don't push a lot of air, especially nearly silent ones going full speed.

This fan will help aid air flow, it's particularly useful if your case has a fan position above the CPU cooler. The flow is strong enough to help but not too strong to create turbulence and disturb airflow.

As an exhaust fan, I'd avoid this one.
