Cooling the CPU/PC parts?

[Treeace]

I'm sorry if this seems like a dumb question I've never owned a PC & plan to hopefully soon build a gaming PC able to handle 4K! Do the Fan/Liquid cooling ruin gaming when they are at there loudest in the process of keeping temperatures down? THANK YOU

They are. Certain fans and types of coolers are most certainly quieter than others. The Be Quiet! Dark ROck Pro 3? The user also matters. They can replace fans with quieter fans and they can also change how the fans respond to heat. 50% speed at 30C or 50C? Up to the consumer and the temps. of the parts. The user can also change the GFX card's fan curve as well. There is also the case to think about. How many fans? What type? Sound dampening? My 212 came with two strips of some sort of material that I place between the fan and the cooler reducing any possible vibration and resulting noise.

In short, my answer to your question is yes. Beyond that it's up to the consumer's needs and knowledge.

The great part about building your own PC is that you get complete control over which fans, coolers, and case you use. If you want to make a quiet PC you can go for a case that has good acoustics (read reviews that test acoustics), use fans that have lower dB ratings (but read reviews because the rated dB is often lower than reality), and choose coolers which use quiet fans while also delivering good cooling performance (again, read reviews for actual noise ratings and actual performance). When the system is hotter, it doesn't run slower unless it's way too hot and gets throttled. You should never experience that, so there's no possibility that excess heat ruins gaming performance.

Now, typically speaking when the CPU and GPU are stressed like when gaming at 4K they'll use more power, generate more heat, and the fans will spin faster to compensate. So it is going to be the case that the PC is louder while gaming versus idle and that's entirely due to the fans slowing down when the PC is idle (or under low load). I don't want to give a typical level, but generally speaking if you have a two fan GPU, two fans in the case, and the CPU fan(s) you would not expect to hear noise above 50-55dB at 1 meter away. This also means if your PC would be closer then it will be louder, but if it's under a desk it might seem quieter. If you use headphones they'll also insulate against some of that noise so it would also seem quieter. If you choose poor quality parts that favor CFM (airflow) over noise you can easily hit 60dB, which is a typical human voice for conversation.

IMO, I've not had a gaming experience ruined by noise caused by fans spinning faster due to gaming. TBH, my hard drives (8 bay external) make more noise than my PC.
