Just thought I would share my experience with you. I got my ML240L RGB in August and I thought it was quiet enough but it progressively got louder until in January I decided to have a look and see if it needed re-seating or something. Upon opening my case I found that the Pump/ CPU Block had been leaking and I was very lucky it didnt blow my M2 SSD, GTX 1080Ti and/or my Motherboard. You may want to check yours. I have attached 2 pics. The heatsink covered in the coolant is on my M2 SSD and the GTX is directly below it.
I wont be fitting that again. Good Luck.
