One part of the community was just blaming Dell’s greediness and/or cooling system which was not designed for such powerful CPU as i7 and another was suggesting to replace the thermal grease and through the power management controls decrease max speed of the CPU.

But there was no consistent/believable explanation/guide of why laptop started overheating and how to fix it. Browsing over the Internet showed that I’m not the only one with such issue. I own Dell Inspiron N5110 which has Intel Core i7-2670QM CPU and NVidia GeForce GT 525M dedicated GPU.

But then when temperature went down and occasional shutdowns didn’t stopped I understood that I have a real problem. At first I thought that the main cause was the summer heat - it was 30☌ (86☏) at the time when I first noticed my laptop automatically shut down because of overheating. Last summer I started experiencing issues when working on CPU bound tasks on my laptop.
