Help me figure out what cooler i need

[Feshh]

Does the cpu cooler effectiveness matter depending on what your graphics card is, or am i able to get away with a lower end cooler no matter what other parts i have. Basically does the heat of the cpu have the same temps with a graphics card(beefier components) as it does without. cuz im gonna be putting an i5-8600k in my pc, and i plan on adding a high end gpu when new ones come out. I just dont know if this will affect the temps of the cpu. I may or may not do overclocking, but i dont wanna spend the big bucks. Pls and thx

gpu does not affect cpu temperature directly.  Only way it does is by increasing internal air temperature of the case

If you have a blower-style graphics card, the card will actually lower the temperatures in your case because it's basically a high-priced exhaust fan. If you have an open-sided cooler on your GPU, GPU exhaust will be vented into the case, which will heat things up and indirectly affect CPU temperature. In most cases, it's not going to have a noticeable effect. If you're running dual 390X's overclocked into next year, it'll get toasty. Ventilation is the key. Coolers can only bring temperatures down to ambient. If room temperature is 25C but the temperature inside your case is 40C, your CPU is going to be running about 15C hotter than it otherwise would. Also, something is probably on fire.

 

To fix the problem of excess heat dumped into the case, you need ventilation. Good airflow in to bring cooler, room temperature air into the case, and good airflow out to get the hot exhaust out of there. Overall airflow is much more important to keeping the GPU's effect on your system temperatures to a minimum. You could have an NH-D15 loaded in there cranking at full power, but if it's pulling 40C air through the fins, there is absolutely no way it's going to fall below 40C.

thx friends

Just be aware that the 8600k doesn't have a box cooler in case you weren't already.

Cheers!
