Summary: I purchased this as a replacement on my cool master haf tower as my front fan had a bearing going out and making noise that was starting to get to me. This one fit right in and worked as advertised.
Summary: Used this to replace a failing 230mm fan and am very pleased with the results. This fan has multiple mounting ears to allow it the flexibility to be mounted in either a 200mm or 230mm opening. Quiet and good airflow.
Summary: I got this fan for keeping my shed cool in the summer. The neat thing is that it runs off of a solar panel and it works great. It keeps the temp cool in the summer. Just as planned. It made for a great project.
Summary: I built a living room system and needed a big fan for heat dissipation in the top of my HAF XB. The main requirement was good air flow, and was followed very closely by quiet operation. I am happy to say that it meets both criteria very well!
