Need recommendations for good fans!

[H4X0R46]

Hey guys, so I just got Watch Dogs 2 and noticed that it pushed my GPU temp to 89C! What are some REALLY good 120mm fans for airflow? Something that will push a lot of heat out of my case??? Right now, I have some really generic fans on the front intake and back exhaust fans, would it be a better idea to switch those, or leave them be and add more fans? My case has 2 cutouts on the top for 120mm case fans. I don't think I have more open fan headers on my board, gonna have to open it up and check it out. Thanks guys!

Some info:
PC: https://goo.gl/NTj6z1 (I changed the GPU and PSU to an RX 480 and a 750w)
Motherboard: Gigabyte GA-78LMT-USB3 Rev. 6


EDIT: I took a look inside, I have one 4 pin header labeled "SYS_FAN" that's open (my fans are connected to a fan controller, didn't notice) and my fan controller has one 3 pin header hanging there.

Those aren't generally going to help you, it's your GPU's fan that's the problem, what cooler RX 480 do you have?
If its the reference model or a single fan version that's why its hot.

It's the XFX GTR RX 480 8GB Black Edition. Shouldn't be an issue, I even have a custom fan curve set and pretty aggressively at that! Hmm......
