Pros: If you're looking for fans (like I was when my top exhaust case fan died) and don't want any rgb and stuff like that, this works. Like the title says, they're fans and they fit and that's all that matters to me.

Cons: None. They work like fans should. I guess it's a con if you want RGB lighting?

Overall Review: If someone needs fans, I'll recommend these. They're fans and they fit.
