I do also, using power saver drops idle power more than anything although my sn850x is ~5-10C cooler using power saver mode.I set my fans in Asus BIOS (tuned) for CPU/case fans, my 7900XT I set in the AMD Adrenalin software so GPU fans are at zero RPM mode ie browsing etc so less power used, very quiet PC and no heat issues at all even with long gaming where RPM on fans kicks in but not loud, easy to check GPU hotspot etc ....
