New Koolance *Dual D-5* Bay Reservoir! (RP-450X2)

This should give some redundancy.



...and for those worried about back flow, I suggest a pair of these.

Tim, If I may suggest a product. Good low restriction, low crack pressure check valves with G1/4" swivel fittings.

WL, would one of these setups be better than the other in regards to reducing backflow? and is backflow guaranteed to happen when using the y adapters?

D_P, I'd say the first one, but only if the 2 tubes that return to the res are as long as possible and the outlet tubes are as short as possible. That should lower the amount of restriction enough to limit or eliminate the back flow. Another significant factor is obviously going to be what's actually in the loop, if you're still using...say a K350 or original Supreme, I don't think anything (except check valves) is going to prevent back flow.

Btw I keep seeing how people want 2 pumps in serial in case one pump fails. Won't the CPU and GPU (programed through control panel) turn off once it hits a certain temp?

At least I did find the articles you all eluded to before about the small difference in temps with 2 loops . For anyone else looking:
Dual Loop versus Single, the facts
Actual Influence of Flow rate

Yes - if you've setup your bios to shut the machine down on CPU fan failure and the tach lead is plugged into the cpu fan header. This assumes that you've done that and that your bios does what you expect. I think most people around here are looking for a belt and suspenders approach to plumber's crack, err, pump failure
