Question about Corsair H115i Pro

According to the specs, this cooling only fits in the front. It is possible that it also fits on top, but there would probably be some kind of problem with the distance to the mainboard (so it would have to be tinkered with).

Guaranteed suitable cooling for the top: Corsair Water Cooler Corsair Hydro H100i PRO RGB (5.20cm)

If you plan to leave the RGB fans in the front, I would recommend these: Corsair H150i Pro
The radiator is exactly the same size as the 3 fans in the front. If you don't want a push/pull configuration (fans on both sides of the radiator), you can use the water cooling fans elsewhere in the case and connect the RGB fans to the AiO instead.

Thank you! I'll have a look at it.
