Help building my loop...

My PC Case would does not have enough space for mounting any 360 mm or 480 mm Radiators.

Therefore, I have a single Corsair HydroX XD5 RGB Reservoir/PUMP combo, and two 240 mm Radiators in my water cooled system (240 mm x 2).
Should I make the loop...
1 - PUMP Out --> GPU --> CPU --> Radiator 1 --> Radiator 2 --> Reservoir/PUMP In
Or should I make it...
1 - PUMP Out --> GPU --> Radiator 1 --> CPU --> Radiator 2 --> Reservoir/PUMP In
Which do you think would be more efficient and why ???

Check out the water cooling sticky threads in the water cooling section (where i moved this thread since this is exclusively about water cooling). They are good to build a knowledge base. ;)

As the links say, loop order doesn't matter outside of the fact that a res should be before the pump (which you have a combo, so it is). Temperature variations inside a properly configured loop is around 1-2C so putting a rad before a block doesn't yield much at all. The loop comes to an equilibrium, really... there aren't 'hot spots' like you're thinking. :thup:

Thank you for your fast reply.

I was thinking the same thing, that the temperature in the loop should stabilize, and any variations along the loop will be negligible.

I guess I will just hook them up in the easiest and most esthetic way possible, with no particular regard to the order of components..

Probably it will end up being...

1 - PUMP Out --> GPU --> CPU --> Radiator 1 --> Radiator 2 --> Reservoir/PUMP In

This, I spent long time worrying about my GPU affecting CPU temps only to discover a clogged jet in my CPU water block was the actual culprit.
