Fan speed control in Fedora 25 for a ThinkPad T420

Hi, I'm new here. I hope I'm asking on the right place, otherwise I apologize but I need to find someone to help me I didn't find any solution yet.

Simply - I'm running Fedora25 on laptop Lenovo Thinkpad T420. And I'm having some issues with Fan speed according to CPU thermals. Fan is simply too loud in comparison to the way Windows 7 was originally handling the Fan rpm

Example: when watching YouTube video, Fan rpm hangs at around 3800rpm (quite loud) with CPU temps at around 55-60°C on Linux.

On Win7 it's a different story. Playing the same YouTube video Fan runs at aprox 2500-3000rpm (sometimes even completely OFF when there is no multimedia type of work) with CPU temps around 60-70°C (which is completely fine for a laptop).

for monitoring under Fedora I used program TLP (with additional features installed for ThinkPads). And for a Win7 I used program called TPFanControl.

So is there any way to change how the Linux is handling the Fan speeds?

also it would be great if someone who knows any tips for better power savings could post them. Last time I was watching a movie with 30% left on a battery charge and it burns through it in just a couple of seconds! :( (using aprox. 7800mAh 9cell battery)

Thnaks! Michal
