I'm looking at the LF3 too because nothing else seems to come close for a 420mm in price/performance, and in my white build I am rather limited in options to begin with. Could go down to 360mm I guess..Thanks for doing that, I have installed a few AIO for family and friends before, but the AF3 is my 1st as a daily driver. Its good to get clarification that my pump is not faulty.
My standard for silent is 'as if it was not there', and do my bios curves without a GPU where possible.
At my stupidly low rpm settings, performing well at cooling, 65c cinebench load.
Bit worried about the pump noise reports, my case is on the floor not on my desk so that helps I guess. Is it true that you don't really need the pump at settings above 50%? Just wondering how much performance is lost in its value if the upper end of it won't be used (if that makes sense).
