Swiftech Apogee GTZ vs D-Tek Fuzion V2 As-Shipped

What would be best for the above setup?

Just like martin said, if you have a multiple loop, then your best bet would be the fusion.

Matters what pump you have...... As Martin as shown, flow isn't all that important once you pass 1.5 gpm.

Yeah, but in my case, I wouldn't pass 1.5 gpm with the GTZ

While having a target flow rate is somewhere to start, the more I've been playing with this CPU block setup where I get the full picture, the more complex I'm seeing this pump heat issue becoming.

For each CPU block tested I'm recording flow rates, but also water and air temperatures. What I'm noticing is that even with the same pump, the more restrictive blocks have a lower water temperature. Even with the TFC 480, I'm seeing around .1C hotter water with the more free flowing blocks.

So in the end you might have higher flow rates, but also hotter water temperatures. The question then becomes, which is better or worse or does the end resulting performance on your other blocks better or worse.

In the end I think there is probably some sort of "Optimal" flow rate to shoot for and it's going to be a function of pump heat dump.

It's all splitting hairs at this point to the point it really doesn't make a difference in the real world, but I'm not entirely sure running a system at 2GPM with a known pump would be better than say undervolting the pump to 1 or 1.5GPM. I'm not really sure what to shoot for at this point but I know the differences are very small above 1GPM.
