(need compatibility advice) Obsidian 500D RGB SE + H150i PRO RGB + bulky GPU

[emiljack]

i have a few question regarding moving to a new case (from carbide 400c to obsidian 500d rgb)

My old cooler (though its still 4 month old) is H80iv2, fitted into carbide 400c (front, upper side)
My gpu is zotac 1080ti amp ext, spec length is 325mm. as it is, its very tight fit between gpu and the cooler

and im about to move to obsidian 500d.
1. would i be able to use H150i PRO RGB with my new case? would it fit with the gpu? is it more wider/narrower than h80i?
2. if im not upgrading my cooler (and stay with the h80i), can i still use the obsidian's included LL fan for push and the h80i's SP fan for the pull, or did they need to be the same type of fan?

cheers

1. Yes, but only at the front, given that's the only location where triple 120's are supported. The Radiator (with fans) is about 2.2 inches thick, meaning that you could only fit 12.3 inch GPUs. That shouldn't be a problem, since the Zotac amp is only 11.8 inches. The Obsidian is quite a bit larger than the Clear 400.

2. You should be fine using two different fans, just be sure they're set to scale at the same RPM in the BIOS. Personally, I don't think push-pull is worth the trouble though.

my card is the ext, and the zotac's spec is:
Card Length 325 x 148 x 56.6mm (12.8 x 5.83 x 2.23in)

My apologies, I didn't take that into account. In that case, you could go with the h115i PRO, which is still a very strong CPU cooler: https://pcpartpicker.com/product/W6RzK8/corsair-h115i-pro-554-cfm-liquid-cpu-cooler-cw-9060032-ww. You'd be able to mount it at the top of the case, thus having no issues with GPU clearance.
