You have the reservoir the pump the radiator the fans some tubing a block for either.
Liquid cooled cpu fan direction.
The first is an air cooler which comes with a big metal heat sink and a fan that pulls air away heat from the cpu.
Best liquid cpu cooling.
If you have a large aftermarket cpu cooler it probably has one or more fans of its own.
Liquid cooling especially when using an all in one aio tends to be quieter than the fan on a cpu heatsink.
Your typical air cooled pc is packed with case fans graphics card fans and a cpu fan or two positioned atop a big metal heat sink to keep your expensive components nice and frosty.
So flip the fan and run it as an updraft.
Water cooling systems whether they are a custom loop or an aio all follow the same basic principles.
The coolant is specially developed to bring the best light dispersion capabilities withing various pc liquid cooling products.
An interesting test would be to measure the difference that occurs when you reverse the fan direction of such a cooler.
Ek water blocks the leading premium computer liquid cooling brand launched a new rgb focused coolant based on a new formula with long lasting stability and vivid addressable d rgb reactivity.
Again this can vary in that there are air coolers with fans specifically designed to reduce noise and fan settings or fan selection can impact the amount of noise generated.
Overall though liquid cooling tends to generate less.
This includes measuring how much a front radiator might reduce cpu temperatures at risk of raising gpu temperatures or how a top mount might do the opposite.
In the very least we can look at liquid cooler placement performance in a few different cases.
When possible direct cpu cooler output to the nearest exhaust fan.
