Sectorix's Water Cooling Build (Obsidian 800d)

[sectorix]

Thats 99% wrong. The water temp. diff in one loop is max 1°.

ok, so im curious ( bare in mind this is my first water cooling build )

1. would a single loop in reverse flow have any effect on the cooling performance ?
2. if 2 loops produce such minor diffrence, why do people bother going multiple loops ?
3. another thing that im considering but want to make sure i dont kill the loop - is adding memory water cooling of 6 slots to this rig.
