The fan runs more frequently than in the past, even with CPU running around 25-30%.
Is there a good way to get a read on the CPU temp?
I see what you mean about user non-friendly snap together parts. http://www.insidemylaptop.com/disassemble-dell-inspiron-17r-n7110/

The other thing you can do (and this is RISKY so only do it while under warranty) is blow the air backwards IN TO the CPU heat exhaust. This will loosen up the junk but could also clog/bind the CPU fan - so if it's under warranty Dell would send a tech or repair it for you. If not I don't recommend doing that.
