Cooling Solutions for Ryzen 1700 Overclocking
Hi, your question is about the impact of choosing 240mm rad versus 120mm rad fans. You're considering an overclock on your Ryzen 1700 and replacing the stock cooler, using a CM Q300L case with two 140mm fans already installed. If you opt for 240mm rad, you'd need to remove those front fans. You're wondering if switching to a CM ML120l RGB or going for the ML240l RGB would be better, especially since your GPU is a GTX 970 G1 and you're unsure about compatibility with the front 240mm. Also, are you missing out significantly by choosing a different cooler?
One fan with a 120mm radius should suffice. Push-pull models won't make much difference in temperature control, and a larger radius only increases the speed at which your CPU reaches its maximum temperature under load... it won't significantly lower the heat without two fans working together. The fans remain the primary cooling component, since water isn't very effective at dissipating heat.

To spark some discussion: a 240 radiator paired with a 120 model does make a noticeable impact, though the final outcome depends mainly on the thermal demand during peak times.
Push-pull also enhances cooling, as radiators and heatsinks help dissipate heat and resistances that a single fan often can't overcome. With sufficient space, this fan configuration works well for most radiators, but due to limited chassis room it's usually just one fan set, mainly because it's the most affordable option.
Accurate point—this explains why a 240 radiator tends to be more advantageous than a 120, particularly with higher TDP (overclocked or not).
Liquids like water and glycol-based coolants, commonly used in AIO coolers, can soak up large amounts of heat before the CPU starts getting hot. This also accounts for why liquid cooling radiators often stay warm for a few minutes after the load is removed.
If you lack enough liquid volume to fully absorb the thermal load while still managing a similar temperature rise, the cooler will keep taking in more heat, gradually increasing in temperature.
