Bgears b-Blaster 80mm Black Fan with 2 Ball Bearings: High-Speed, Extreme Airflow Review

These are some cool fans man they really put out CFM and keep it cool. The only downside is that they are pretty noisy at full speed. May be too loud for some people. Also, these fans work great and I have two of them strapped to my case blowing against my fiery Radeon R9 290X graphics card and keeping me cool. These are the most powerful 80mm fans I've seen and I plan to buy more fans from Bgears soon.

I recommend it.
