I set my fan profile to be dead quiet until the CPU temp gets to about 75C, then only slowly rise it until about 90C. ALWAYS run your AIO pump at full speed because you're using water to cool the CPU. So long as it's flowing it's cooling the CPU even if the fans are off, the faster it flows the better it cools. Unlike the metal of air coolers it takes a very long time (hours) for the water in a 360mm AIO to heat up.Yep, under load, it's climbing all the way up to 4.6GHz, but the RPM too.. Do you maybe know, how high with the temperatures can I leave my 360 AIO on 800-900RPM? Because whenever I do something a little bit more demand than Chrome browsing, RPMs jump to 950-1000RPMs (Which sounds quiet but it actually annoyes me, because I'm not wearing headset and the PC is distanced from my ears like less than 20 centimeters..). So, can I set my fans in BIOS to run 700-800RPM even at 60C? Would that be fine?
Yeah, I'm just concerned about those idle temps because I don't want to shorten CPU's life, I don't know if 50-55C can do it on 5000 series though?
50-55C is actually quite cool for modern CPU's so you've nothing to worry about.
