Question: Swifttech says the radiator is 34mm thick. CoolerMaster told me today that the design size for a top radiator is 29.6mm. To the best of my knowledge the only radiator that size is the HWLabs GTS240 Stealth; that radiator is exactly 29.6mm.

I'm thinking of getting the CM690 II Advanced for my new system; my current system is a CM690 (original) with a Thermochill 120.3 on the back. However, I want to make it more compact. Air cooling (I have another thread on that) is very problematic; the alternative is an inside radiator. A bottom radiator is not an option; too many disks.

The XSPC Rasa 750 kit has their waterblock, 2 5.25" bay resevoir/pump, and their 35mm thin RS240 radiator. Ideal? No, but better then aircooling, inexpensive, and easy to install: no brackets with a CM690 II top install. However...will a 35mm radiator fit?

Note: The system is in an open frame using a Noctua NH-C14 HSF for the time being.
