Cooling Revolt 2 Cooling Upgrade

[Napue]

Hello I will try to keep this short; I would like to replace the very old & used cooler currently installed since starting to get noise on start up that eventually goes away, but losing my hair trying to find suitable cooler.

Case: Revolt 2 (ibuypower) Motherboard: Z270M-itx/ac (1151 socket) Cooler Currently Installed: Corsair Hydro Series H55 (120mm) Guide from ibuypowers website with dimensions/build guide: https://content.ibuypower.com/Images/Support/basicGuides/Revolt_2_Build_Guide.pdf

Looking to go to atleast a 240mm cooler, but struggling to find candidates that fit the cases restrictions, the biggest being the pump height. If I am reading correctly the pump height(part that goes on top of cpu) has to be under 30mm w/ side exit tubing. Hoping to get some ideas from you guys with more experience then I.

The Thermaltake Water 3.0 Extreme 240mm seems like it would be perfect, but it is currently out of stock. The 120mm is in stock though. Another option is the Be Quiet! Pure Loop 240mm which the pump on the tubing, so maybe it would fit? However, I think the old pump is a generic Asetek design, so you should be able to find multiple options.
