Question about Corsair 4000D Airflow

No, the Vengeance RGB Pro Ram modules are too high and collide with the AIO. Corsair vengeance lpx and crucial ballistix sport just fit (I have tested both). For this, the fan must be briefly removed from the AIO in order to install the modules.

I myself have g.skill trident z rgb ram, and I'm glad I chose a 240 AIO (gigabyte waterforce X) because with a 280 the MBO and/or RAM would block.
