Keeps an I5 13600k between 29*C and 70*C between idle and high load, mostly doesn't rise above 65s*C at high load. When you consider 13th gen processors are high heat generating, can rise to 80s 90s up to 100*C, that is excellent performance.
Longevity? who knows.
Noise level? radiator fans are the loudest in my system, which is overall a very low background hum, you can always replace the supplied fans with after market quiet fans, but i had venture you wouldn't get much of an improvement, it's the air you hear not any mechanical noise.
I mounted it on top of case as exhaust, the pump is in the radiator not in the cooling block like majority of AIO coolers, so if air being trapped is a worry, use a a washer or two to raise the non pump side of radiator a little, probably overkill and unnecessary but there you go.
Overall totally working fine at great temps, would recommend, terrific value price vs performance.
