Would you guys go with liquid cooling or standard fans?
If you are thinking in overclocking, standard fans will not work, you will need to change the CPU/GPU coolers to overclock those components...
If you are not into overclocking, you can keep the default ones, they were made to work with those components. if you live in a hot place (like myself) it is good using other coolers too but not really necessary...
@if the question was about AIR cooler Vs Water cooler.
Custom water builds are very good but require some maintenance, and if you don't know how to do it, you can finish with a wet system.
Locked coolers, are good because they don't require any maintenance, and specially because you will be able to keep the sink in another place of your case, and not focusing all the heat on the top of the motherboard.
Air coolers are normally the default option, some are great, some are just good. the main problem with them is that they use a big space inside your case, but yes they are cheaper and do the job.
