I had a 9520 for about 5 years. I had two issues, which was a broken left hinge (4k touch screen was two heavy for that part, I believe in the XPS 15 actually didn't suffer from the same issue), and swelling batteries, which caused various knock on issues. I also experienced the same issue with batteries from the dell latitude I got from work. Seemed to be a dell thing for laptops left plugged in constantly. I never had to deal with overheating issues despite having a Xeon (although it did get quite hot). Its a shame because otherwise I really liked the laptop. Gorgeous screen, good trackpad and keyboard, and a perfect size imo.
