Does water cooling loop order matter?

Loop order really matter. It will not affect overall experience of course but your heat dissipation efficiency will be worse. Whole water not heat up at the same time or cool down. Use temp sensor and you will see different temps everywhere in the loop.

Do you need two radiators water cooling?

The rule of thumb is to use at least one 120mm radiator (section) per each water cooled component plus one additional section. For example, if you’re liquid-cooling a CPU and a single high-performance graphics card, it is recommended you use at least one 240mm (2x 120mm) radiator for good performance.

Is 240mm liquid cooling enough?

240mm is enough. You will always be able to further increase it’s cooling performance by setting a push-pull setup and/or using better static pressure fans.

Is a 240 rad enough for GPU and CPU?

With a 45mm or 60mm 240mm radiator, you will be good. I just need to remind you that thicker radiators like static pressure optimized fans and you will need to run the fans at al least 1200-1500 RPM to get the benefits of a thicker radiator.

Is a 360 rad enough for CPU and GPU?

A 360 will be enough, but fans will have to operate above 1000rpm. Any 45mm or thicker rad should do the trick. A 60mm should be plenty for this.

How much heat can a 120mm radiator dissipate?

Any single 120mm radiator is actually capable of removing more than 200W of heat by itself, but this is a design limit and the heat isn’t removed at any particular stable temperature that suits us, which varies person.

Do you need two radiators for GPU and CPU?

Yes. However separate radiators for CPU and GPU are better unless you can only fit say a 120 and 360 rad. If rad sizes are closer, you want the components on separate loops.

Does the 10900K need liquid cooling?

Intel’s i9 10900k Processor is an exceptionally powerful CPU. The cooler dissipates the heat from your i9 10900k processor over a large surface area and uses an air- or liquid-based system to cool it and keep it operational.
