All painted up!
Just occured to me today how my cooling system is 1,000% overkill. For reference my last computer used a i7 4770k cpu cooled by a Corsair h100i. I overclocked that with around 1.4 volts and it was running at around 70 degrees celsius.
The h100i has a very approximate volume of 720,000mm³
The h110 has around 840,000mm³
So true enough that only had to cool my cpu. So I feel safe saying if you were to double that you could easily cool a gpu as well. That would be around 1,500,000mm³ to cool one cpu and gpu, just like the computer I am building.
Here is the overkill part. My top radiator is 3,500,000mm³..... and my bottom radiator is 2,300,000mm³ totaling around 5,800,000mm³ of radiator space in my system. Not saying I regret this at all. Just a random realization.
