There are two issues that I've been experiencing that I think are related.  First some background, my laptop has 32GB RAM, plenty of free storage, all drivers updated, no other known issues.  I only use it for basic tasks like browsing, e-mail, etc.  99% of the time it's sitting on a stand and it's closed.  I use two external monitors and a Bluetooth keyboard/mouse combo.  

Fans:  Over the last year or so I've noticed that the fans are quiet active.  Seems like they are on a majority of the time.  If not majority, then they certainly turn on and off quiet often.  During this time, I see CPU usage is also increased.

Mouse:  The mouse studder is becoming a big issue.  It wasn't too bad a few months back but now it's almost unusable at times.  The mouse studders and there's a lag.

I know the laptop is a few years old but I don't think it should be having these types of issues.  I don't do anything heavy on it.

Anyone else experiencing any of these issues?  Is there any troubleshooting I should try?

Thanks!
