Summary: I probably didn't need these fans even though the case fans were terrible. The polar vortex has arrived, and I don't use heat in my small apartment, meaning the environment cools my computer greatly with my CPU idling at 6C today. Usually it idles at 10C. This is with the stock AMD fan on an FX 6300. Why pay 100+ for liquid cooling when you can save money on that and your heating bill? No overclocking yet, but I may see how much I can push it for fun.
Pros: Does what the specifications say it does. Runs very quiet. I bought two of these because I bought a Rosewill case that came with two 800 RPM fans.
Cons: First time I started up the computer with these in, the fans would not run automatically. I spun both fans myself and that got them going. Ever since, I haven't had an issue, so it's not really a con; it's just something to be aware of.
Summary: I willl look to buy more when the others give out. Led's added to it would be cooler if they had them lol.
Pros: Cheap fan, pulls a lot of air, or push depends on what ya use it for. I use this fan to pull cool air in the front of my tower and it does it great. Out of all 9 fans I run. This one is the most quiet of them all. But I love the humm of several fans and flashing lights. But airflow is essential for a gamer like myself.
Cons: Not to date. Just have to keep the dust off the screen or it can't do its job, but that is regular maintenance.
Cons: I bought this fan to replace a stock Rosewill side fan in my Blackhawk case and this fan is SIGNIFICANTLY louder at any RPM so I am very disappointed that I have to find a different fan that is quieter
