Thanx Muffdiver
I was under the impression that loop order was less significant, although it will probably have some degrees of difference.
My Loop is this:
Res > Pump > NB > SB > GPU 2 > GPU 1 > MOSFETs > CPU > Res
GPU 1 is 2 degrees warmer than GPU 2.
GFX cards are two XFX factory overclocked 8800 GTX
maN1C: I am sure the water is flowing yes. When I added color it spread throughout the system. Water is also flowing over the aquaduct bridge and it is def. cooling the system. GPU 1 under stress test tops out at around 64 degrees (idle now is 53 degrees).
The aquaduct also has temperature readings of the water inbound and outbound.
