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
Summary: It's a good fan, but because it's cheap you may get a defective one right out of the box.
Pros: The fan pulls a good amount of air on my CPU cooler. it's also cheap and made by a good, reliable company.
Cons: My fan makes an annoying rattling noise for some reason. I just ordered it as well and it did this straight out of the box, so I didn't damage it. I'll probably be filling out an RMA for it soon, but not really wanting to do that because it's such a pain uninstalling fans with my case. Whatever haha.
