Corsair finally got the message from MANY previous reviewers and started tapping (cutting holes) the heatsink so you can just screw on the fans instead of bolting on the fans . Therefore, installation was easy; Make sure the pump mounts are properly seated in the pump groove. DO NOT overtighten the CPU thumbscrews - gently, not force, apply a little on each side of the pump. If the thermal paste of the CPU/pump block is aging, you can turn the thumbscrews a little more. No ARGB on the H115i XT Pro 280mm 2 x 140mm fan model, except for the pump, but the fans are pretty quiet, as is the pump. The finger on the hose confirmed that the pump was working - it wasn't audible. Cools my Ryzen 3900X under load. Expensive but better than stock and the hole problem is fixed - maybe Corsair will take a look at the reviews! Downloading the iCue software is sufficient.
