[SOLVED] How many radiators do I need?

[nsoppa]

Hi everyone, I am planning to build a custom hardline water-cooling loop. I want to overclock an Intel i7-8700K and a GTX 1070 Founder's Edition. If I were to overclock both these parts, do I need more than one 240mm radiator? I plan to build this in the Thermaltake Core P1 Mini-ITX case, so I can only fit a 240mm radiator. Do I need to choose a different case and double up on the radiators for the best temps, or is 240mm good enough? Thanks to everyone who answers!

You should aim for 360mm minimum with that setup.

If I use 360mm total, should I use 240 for the CPU and 120 for the GPU, or the opposite?

Since its all one loop it wouldnt matter, both components can use all the radiators.

Correct...single loop cools all components that are contributing thermal load to the loop.

360mm + 240mm would probably be the right balance before you hit diminishing returns.

Considering overclocking of each component, this is a safe estimate; probably a little more than needed, but certainly better than "less than needed".
