[SOLVED] Benefit/Impact of an external radiator

[tmcc]

Hi there. I have a custom loop in this order

1. D5 pump/res
2. 120mm rad/fan
3. GPU blocked 3090
4. 360mm exhaust rad/an
5. CPU blocked 11700k
6. 280mm front intake rad/fan

My ambient temp is 26C, my coolant maxes at 40C under stock clock game loads.


I was thinking adding an external radiator 360mm 6mm exhaust right before the GPU.

So the order would be

1. D5 pump/res
2. 120mm 45mm intake rad/fan
3. 360mm 60mm external exhaust rad/fan
4. GPU blocked 3090
5. 360mm 45mm exhaust rad/an
6. CPU blocked 11700k
7. 280mm 45mm front intake rad/fan

Is this just overkill? I'm trying to get temps as low as possible. Thanks

Whatever you do you'd never reach ambient temps and stay to about 10c above them.
