Do I need to build a "gaming" computer?

[InbetweenDreams]

So I looked at all the parts, thanks for compiling that list! I actually do like the case, the blue LEDs are neat and considering blue's my favorite color, I have no complaints at all. What's the point of the cpu coolers on some builds that I see? Other than, you know, doing the obvious (cooling) why do some builds have it when others don't?

I haven't had any issues with OEM coolers from Intel. Some CPU's (AMD in the past) would run very hot and folks like to overclock. So an aftermarket CPU cooler can keep the CPU cooler than an OEM one in some cases. I don't think for the build I listed would really benefit from an aftermarket cooler, some may disagree and here's why:

While your computer will run stable and everything from the surface looks fine behind the scenes there are always to some extent math and logic errors occurring, this effect increases as the temperature goes up...also more common for graphics cards. This is why a lot of people like to water cool their computers, they're able to get rid of heat faster enabling them to overclock and improve performance overall by keeping the temperatures lower.

However the biggest benefit is lifespan, cooler computers tend to last longer. I also feel that used hardware last longer than hardware that sits around. I say that because every computer I have built has always lasted longer than 5 years... In fact I just added a new video card for 4k resolution in an 8 year old computer.
