Go's to show ya we worry too much about loop order.

Fixed. By doing parallel he dropped the flow rate over each block by about 50% yet his temps barely changed. As long as their is still turbulent flow over the blocks and through the radiators temps shouldn't really change much.

This isn't so much about order as it is with flow patterns. IMO order doesn't have much effect at all (maybe 1 - 2c max) but a parallel loop without matching restrictions could have a drastic effect if the majority of water flow ends up favoring one leg of the cct vrs another (path of least resistance). I wish I knew more about flow dynamics in a closed loop though, because I'm wondering if perhaps fast flow past the output of the slower loop portion doesn't create a vortex that acts as a vacuum to get flow through that "slower" portion.

Does that make any sense at all?

Ya was surprised thought it would see a bigger temp hit.

Bernoulli's principle - Wikipedia, the free encyclopedia

ouch my brain.... ;)

I've studied a little bit when applied to aircraft wings and lift, but am not really sure how to apply the correlation between pressure and flow rate (on a wing they use two molecules which split at the leading edge and claim that they still meet up at the trailing edge thus the one on the portion of the airfoil with more surface area (more distance to travel) must travel faster and thus the differential in speeds creates the differential of pressure and voila we have lift.

Well... best maxed out simultaneous GPU + CPU I could get going (Kombustor + 3 thread CPU which maxes CPU and hits GPU for what appears to be about 93%) has the CPU peak @ 57c and GPU running around 53c. I can certainly live with those numbers. :)

Nothing wrong with that. I am surprised, but the numbers don't lie.

Yeah, I'm a bit surprised as well.

I'm doing everything in my power to see if I can overstress the loop under my standard OC conditions. Currently stress testing with a slightly better load methodology that pegs GPU @99% as well as all CPU cores @ 100%. Both CPU and GPU seem to have settled at 62c (GPU cycles between 61c /62c) after 1h+ as recorded by core temp and MSI Kombustor w/ ambient reading 27c.

Keep in mind that this is a single 220 rad, 2X GTs with the case sides on, and a 580 in the loop. Happy??? Hell no, I'm ecstatic with those numbers considering I was skeptical that a parallel loop would work at all. :)

edit: So that's 1 1/2hr+ of the max CPU/GPU stress I can come up with (without starving the GPU Stress test).
