Default Re: How much restriction is too much restriction?

Yes. My modelling is done with:

Swiftech MCR220QP with two fans at 7v.
MCP655 @ 5
Storm on 70W CPU
MCW6002 (to represent GPU block) on 30W GPU {watching TV is not playing 3D game hence lower wattage}
2 meters of 1/2" tubing.

Adding in the GPU block adds 2.1°C to the CPU temp.
Adding in another 50cm of 1/2" tubing drops the flow rate by like 0.1 LPM.

I guess the addage of 90° turns being flow kills is from back when we wanted 10 LPM flow rates due to the blocks being low-tech. Impingement slows the flow rate down and hence the bends are now not so bad?

Yes. Order of components has trivial impact on temps, except always put res before the pump.
