D30 Reverse Airflow 140mm DRGB PWM Fan Triple Pack - White

I bought these fans no more than maybe 5 months and I've got to say they are some of the nicest looking fans I've ever seen, the RGB is perfect and they were super easy to install into the Havn HS420. Now, why have I given these fans two stars? Because a lot of the time some of them aren't on, and I not talking about some sort of fault with the RGB or they're just not spinning, I'm talking about the connectors. Basically the way that these fans connect with each other is by a connector on the side which means that they are well hidden and are not leaving any kind of connection slot on the end of the fans like the Lian Li ones do, but I'm not going to lie, the plastic that holds these connector in place is absolutely atrocious. Even from the day that I built the pc they were popping out only maybe a couple days after I'd have to pop them back in and the only way I can get them to stay for more than half a second is pushing the plastic on the side of the fan towards the connector so that it actually stays but then I'll end up coming home from work just to see that its popped out again. So do I recommend these fans, yes. But only if they fix that terrible connector. Because I've ended up spending £30 each on a fan, only to now have duct tape on the sides and prey that they say which they still sometimes do pop out still.
