Computer restarts randomly sometimes after the fans get loud

The problem is you have high temperatures. Your fans getting loud are them increasing in speed to combat the rising temperature of your CPU, and when it fails they restart. What temperatures are you getting, what CPU do you have, what cooler do you have, and how many case fans do you have?

I have an Intel i5 4670k, my cooler is a Cooler Master V8 GTS and I have 4 case fans (2 in and 2 out).

Arch's assumption was based on your fan's operation: they do react to higher system temps.

So let's have a peek at the temps with your computer temp monitoring program of choice (i regularly use realtemp). You might also want to peek at your bios' system auto shutdown threshold settings. For an i5 4670k, it might be at 75~80oC.

Is it summer in your region? Do you have an overclock? A hotter environ makes that stable overclock in cooler times, unstable. Hell, even without overclocks, some systems suddenly suffer from the hotter weather. These year's hot weather isn't like the past as well, I chalk it up to global warming.

It's the end of Autumn where I'm at and the fan temps are at 25-33 Celcius on idle and about 47-55 Celcius when running games like Battlefield 4. My CPU is currently running at stock settings and has not been overclocked yet.
