So, I bought a video game on Steam called Derail Valley about a month ago. I had to run my CPU fan at the fastest it would go, and that gave me an average temperature of about 186 degrees Fahrenheit, occasionally spiking up to 195. However, recently, even with the CPU fan at max speed, the CPU stays at 197 degrees (92 Celsius.), the max it goes. Meanwhile, on "auto" fan mode, the GPU stays at maybe a maximum of 168 or 172 degrees.
I knew this was an issue, do first I tried to first set the maximum processor power to 95%, but that didn't work, so I set it all the way down to 75%! And it still isn't doing anything!
When the first thing didn't work, I bought a cooling pad by the brand Havit. It seemed to work for a little while, but just like the first thing I did, It seemingly stopped doing anything after a while.
I then took off the back cover of my computer, and carefully brushed the dust out of my computer with an old (but still clean) toothbrush. I got all the dust out, but it still isn't doing anything. I've heard that you need compressed air to clean it out, but I am unsure of how to use it, and if it can break my computer.
I've also heard that the thermal paste that comes with these computers isn't very good either, so do I need new thermal paste? I am scared to break the computer, but If I do need it, is there somewhere I can get it applied? Maybe the Geek Squad at Best Buy could help me out.
The CPU temperatures are 197 degrees, and the GPU is 168 or 172, I don't remember. Are these temperatures normal, and is there anything I can do about them? I would like to play Derail Valley again, I find it really fun :)
