Best cooling loop?

post #1 of 2
Thread Starter 
I know this is largely preference, However, is it better to go GPU first and then CPU or CPU to GPU?

GPUs usually run a little hotter so they could benefit more, however, If I go to CPU it wont heat up the water too much before it goes to the GPU...

I think the best solution would be to add another Radiator and go CPU>Rad>GPU>RAD>RAD>Pump/Res

But what would you guys recommend?

This has been discussed many times in the past. Have a read through the stickies, or search for loop order.

Basically loop order makes minimal difference as the water temperature does not change by much as it goes through the loop. We may refer to "hot" and "cold" water but in reality once the temperatures have leveled out, after ~10mins of constant load, the water temperature typically varies by less than 2°C through the loop.

Please note that, as some people think equilibrium means, the water temperature is not the same though the loop, if this were so it would not be moving any heat.

If you want to get mathematical about it, it takes 264W to heat water at 1GPM by 1°C.
