The fact is that your water is actually heating up (15 deg delta) correct? As it is heating up fine - this implies that heat is being dumped from your CPU/GPU's into the water correctly.The problem is that you are not extracting enough heat from your water which is what the radiators do. Increasing the flow will have little impact on your water delta temp.
I suspect that the internal lower section of your case is heating up as airflow is stuck inside between the two rads with not nearly enough exhaust opportunities.
Can you measure the temp inside the lower section between your rads? I would not be surprised that both of the rads down in your lower compartment are simply not working well due to airflow configuration restrictions.
With normal flow rates, this is true . . . . .
But if the flow rate is compromised for some reason, the flow rate thru the rads may be low enough that it's become laminar.
The reason why rads use a flat tube design is to ensure turbulent flow at relatively low flow rates, but that doesn't mean that the flow rate can't drop so low that it becomes laminar.
If that's the case, all those big rads aren't going to mean squat
There are a couple reasons I've seen over the years that cause really low flow rates where they should have been Much higher.
I've had fittings with very small bores where you'd expect at least twice the bore size, and some fittings have at least a 2mm longer thread length than others.
With the long thread lengths, they can go too far thru what they screw into and just barely not hit what's at the other side of the thread. (outlet of a CPU block for example)
All the pumps in the world aren't going to move watermelons thru a hummingbird's butt
Steezy really needs to see what the flow meter tells him at this point to really know what direction to move in to get the temps better managed.
Not the best pics, but you see what I mean about unusually long threads, and strangely reduced bore diameters versus normal on the left.
The stock Bp anti cyclone res fitting is another issue, especially with multi pump setups, it's amazingly restrictive when compared to their hi-flow version.Edited by IT Diva - 2/13/16 at 4:01am
