beesmoko :
I see your point, so that those people that are saying 'use liquid cooling for better performance at overclocking' those are just gimmicks while in the other hand you can get almost exact performance with cheaper air coolers, right?
the thing is that AiOs are technically have liquid, but practically are just wannabe liquid coolers.
they have anemic pump and crappy aluminium radiator that requires "insane" fans speed to cool the CPU beyond air coolers.
On the other hand, put a 2000RPM (120-140 usually equipped with ~1300RPM) fan on air cooler and you will get same or better result at the same noise levels.
In real life, here are examples:
I was able to push the GTX 1070 50MHz more than on air and that after power mod.
The CPU is able to do exactly the same at a bit higher temps - anyway VRM overheats first on my MB.
Yes, the temps are lower. especially on GPU. but who cares if it's within the spec.
Yes, my system is gently humming under unrealistic synthetic load.
But that with ~800-1000$ worth of custom loop which is leaps and bound above the best AiO you can find.
