laptop overheating, what to do?

[ICGC10621]

I'm using a Dell Inspiron 7373 2-in-1, and ever since I started playing games on it (I know, I'm stupid) my CPU has been getting really hot even though I'm not performing many tasks. At idle, it sits at high 40 to low 50 degrees Celsius and easily reaches 100 degrees if I put some load on it. I'm wondering if I should get some compressed air and blow out any dust that may be inside, or should I apply some thermal paste to the CPU, or both. Anyone know what to do?

Both, or either.

At least blow out any dust, you should be blowing it out monthly anyways, to clean it out.

How long has it had this problem? You said idle it's at 40-50 degrees, I would almost wonder if dust is clogging up a fan or two inside.

I'm guessing you know this but 100 degrees Celsius is a really dangerous point for components, especially if it's that hot for a good amount of time.

I've had this problem probably ever since I started to keep track of my temps, which was the beginning of this year, and probably before that as well. My battery life has suffered also. I can't even go 2 hours without it dying, even with battery saver on, and bluetooth and everything else turned off.

This is due to KBL-R CPU running too hot. Many other models also suffer from this

Battery life will degrade over time
