I'm wondering how 3/8 ID tubing is going to have better performance than 1/2 ID...?
FWIW, I've switched a couple of systems from 3/8 to 1/2 "just to see" - and saw no improvement in temps - this on two systems both optimized for low noise (innovatek hpps pumps, swiftech 5002 or 6000 blocks). YMMV with higher performance systems.

Oh - the 3/8 ID is a lot easier to route in the case (I'm using soft silicone thick-wall tubing to reduce pump vibration transmission - but it's bulky.) So 3/8 is higher performing in the sense that it blocks less airflow through the case - and a lot of "optimizing for low noise" is ensuring that your case have as little air restriction as possible.
