Hello to the folks in the ProCooling forum. I usually hang out at amdmb but spent some time here researching before I went into water cooling.

I went from a Maze2 to a Maze3 witout any earth shattering improvements. Maybe 1-2C tops. I run an MP1800+ at 1784 (11.5 x 155FSB) on an Iwill XP333R. I have a Black Ice Extreme rad, Eheim 1250, 1/2" lines, use distilled water with water wetter, 4 ounce to the gallon mix. I am still on the remains of a tube of ASII. Loaded temps in 21C ambient are 33C with the Maze3. Just a FYI, I duct my radiator intake to ambient air because of warm running SCSI drives adding to inside case temp.

I found the Danger Den maze's sure like flow. With the Maze2, Eheim 1250, 1/2" hose and 6 x 6 core, flow was 95GPH. When I dropped to 3/8" hose, flow dropped to 64GPH and temps went up 1C. Sure not a big increase, but I want to get the best I can before it comes upstairs where it's warmer. Yesterday I finally modded a 3/4" to 1/2" PVC reducer bushing to fit into that short fountain fitting you get with the Eheim 1250. It has like a 11/16" female ID with that metric o ring male thread. I cut 3/8" NPT pipe threads into the bushing, turned it down to fit into the metric fiting and used PVC cement to glue it. A 3/8" pipe to 1/2" barb takes me to 1/2" line without an adapter now. Getting rid of that 3/8" ID outlet gave me near 1C reduction in loaded temps on the Maze3, from 33C to 32C. If I use a pusher and puller fan on the radiator, I can get down to 31.2C.

I haven't flow tested the system yet, still in process of trying to get the new case done so it can get anodized. I will flow test when it's taken down.

The temps I posted are measured with a Dig Doc5 sensor touching the CPU core. Depending on how much air I blow on the MB, my MBM5 CPU reading can be from 1 to 5C different. The PC70 is a deep case and those 80mm fans don't reach too well. I watch the CPU temp go up with the MB temp depending on how I position the fans ( I don't want to do side fans so I am complicating things for myself). If I pinch the hose from the pump, the CPU temps go up immediately so I guess the actual temps are somewhere between the two. Running my MP1800+ at 1800+ (1.53), default volatage (1.75) my temps are 27.5 idle, 28.5 loaded in 21C ambient. I estimate the O/C to be at 91 watts if I did the math right

I run the retaining nuts near all the way down but make sure I don't bind the coils. Did that once and temps went up a couple of C cause it was cocked. Was lucky that time.

Will post some links later...

Radiator above PS.

Duct to case side.

Side air intake.

My lit up reservoir.

Lit reservoir through top blowhole.
