Corsair h80i help

[A bottleneck of Coke]

I may be investing in a h80i refurbished and due to the aesthetics of my case I need to stick the radiator at the top of the case like the h100i but all the photos I've ever seen have it at the back also should I even buy a refurb because it does have a warranty

Hey mate, I've tried to install a h80i in a 300r like that and I could only fit in one fan and the mobo clearance was very tight. I would try to get one with a warranty although Corsair's stuff is very solid.

I have bought several Refurbished H100i, and 80i coolers and haven't had 1 issue yet in over a year

the only issue is the refurbished ones don't come with there new fans so if your going to get one you might want to swap the fans for aftermarket ones

like Corsair SP's or bitfenix specter pro's

I personally wouldn't go with a single 120mm rad. Even if it's a thicker one.
