If you are running a default clock using Prime 95 at 80c I can see your concern. A Corsair H80i is considered a quality product. I don't like their fan because they are noisy to my ears. I'm a lover of Noctua fans. (see my specs).
Noctua.at - sound-optimised premium components "Designed in Austria"!
If you could remove your hard drive rack from in front of the front fan and still have a place to mount your hard drives it would help case air flow.
You have a very nice mid size case. I do believer H80i would be a improvement although not drastic. Of course your will never know unless you try it. I have no idea how good thermal compound on Corsair coolers are because I alway use Arctic Silver5.
