[Blade 15 2020] Reduce heating / tune fans speed

Hi guys, I'm trying my new laptop: Blade 15 (2020) 144hz GTX 1660Ti (Bios v.1.0.4). I'm using it plugged, with "better battery" mode and only skype opened and this is sufficient to make it warm enough to have my wrists sweat. If I manually turn on the fans (that are off if let in auto mode) the situation gets better, but the minimum rpm (4300) is loud enough to make uncomfortable to be in a public place. Is there a way to better tune fans speed or anyway to reduce heating? I already looked into under-volting but it was locked since version 1.0.3 of the firmware and only reducing the maximum processor state seems to be insufficient. I'll be grateful for every suggestion!
