3 rads - Cooling CPU & GPU?

[Dirk Diggler]

I'm currently designing a custom loop. When complete, I will be cooling CPU and GPU. I have no intention of having 2 GPU's, and I won't be fitting water blocks to MOBO, RAM etc.

So, I originally planned for 1x360 Rad and 1x240 Rad. However, looking at it I think with a bit of modding I could fit another 240 Rad in the loop. My question is, would there be any point? Would I see any difference in temperatures on the CPU and GPU with that extra Rad in there, or will it have a negative effect of providing more resistance to the pump for little or no gain in cooling?

I don't want to go to the expense if there's no gain, as I could use the extra 240 rad space for 2 extra cooling fans shifting cool air into the case. On the other hand, if there's a benefit to cooling potential in the loop which could aid in extra overclocking...

you may gain a couple of degrees, its not really worth it tbh unless you like overkill

I thought as much. I think I'll go for fans instead of rads, and if I add extra hardware tht requires cooled in future, I can always add another Rad.

Cheers.
