Which cooling system to choose for a PC?

Question

Iron

Guys, help me choose a cooling system for the Intel Core i7-8700k processor
Motherboard GIGABYTE Z370 AORUS Gaming 7
The choice fell on these models:
Noctua NH-D15
Cooler Master MasterLiquid 240
Cooler Master MasterLiquid ML240L RGB
For the price, of course, I don’t want to take something completely wild but I'm afraid to guess.
I really hope for your help

Answer 1

I have been using Zalman OPTIMA or Zalman Performa+ all my life.
Everything is perfect. I would have taken them. Well, or Thermaltake Contac Silent 12

Answer 2

Noctua NH-D15

Answer 3

For the price, of course, I don’t want to take something completely wild,

It sounds especially funny from the owner of the motherboard for 18 thousand.
Noctua NH-D15 - Always the first in the lists, while there are few worthy competitors.
In general, visit Overclockers , there are tests and everything else.
UPD : You have no sense in dropsy. You have a processor without index K, i.e. is not chasing, so spending money on water is pointless, since you already threw money away on an unnecessary motherboard.
Make sure you don't have high-profile memory and the Noctua cooler won't hit it and take it. If it resists, then look towards Thermalright Macho.

Answer 4

I don't understand why it's so expensive. Deepcool REDHAT with 6 heat pipes for 2500r cools even overclocked 8700k, and even more so yours.
