A good liquid cooler can offer better somewhat performance than an air cooler.  But since price is a consideration for many people, and that’s money you can put into other parts which make more of a difference, it’s not recommended for the majority of people. 

Pros of Liquid Cooling (compared to air coolers made for performance)

  • Makes less noise at very high loads.
  • Does not block RAM slots
  • Is more space efficient for Mini ITX builds with narrow width.
  • Allows more room for the hands to work in while repairing/upgrading the PC.
  • Can choose which side of the case you want to exhaust the hot air from.
  • Certain liquid coolers can be used on your GPU in addition to your CPU.
  • Aesthetic appeal of having a luxurious and futuristic looking machine.
  • Generally offers more superior clock speeds and better performance.

Cons of Liquid Cooling

  • If you are not overclocking, it’s absolutely pointless.
  • If you aren’t gaming at 4K or above 60 frames per second, you probably don’t need it.
  • The performance boost is meaningful, but not significant.
  • Liquid cooling generally costs about twice as much as air cooling.
  • In the $50-75 price range, air coolers are generally superior.

Who is liquid cooling for?  Hardcore PC enthusiasts who already have a great CPU/GPU/RAM/Storage/other parts and want to max out their PC. Consumers with a high budget.  Everyone else – not really worth it.
