I've just built a new computer, in which the CPU hits some peak temperatures between 65-85 °C.
I've read this which states:
Your CPU, meanwhile, shouldn't be hotter than 75°C/167°F.
Other than the obvious water cooling and opening the case to let the hot air out, are there any other ways to keep the desktop PC cool?
Keep in mind, it is brand new, so there isn't substantial dust to warrant cleaning out any vents or fans on it.
For clarification, here's an image of the PC with it's case off.
I'd like to note, that it hits the high temperatures when doing CPU intensive tasks like gaming or various other on screen tasks like programming (This includes various other programs running at the same time causing high use)/rendering.
I'd also like to note that I run a 3 monitor configuration through this setup.
