Hey so I'm looking to get a glacier 240l and I want to know if anyone has any idea of how loud it would be. I would be replacing the stock fans with noctua nf f12's.
You wont really notice the pump noise unless it is faulty or has a air bubble trapped.
Good move in replacing stock fans with those noctua fans even at full throttle noise levels will be good.
The pump on these kits is noisy at full speed. If you keep it around 40 to 60% though you won't be able to hear it over your fans.
My Swiftech mcp655 is all most silent in my case. I can only notice it if air is running through it.
