AIR FLOW DESIGN AND COOLING FLOW
Well this how I came up with the idea.WELL LET ME EXPLAIN.
First of I could have moved the radiator to the top, but with drawbacks. I wanted to keep my water
system from making any up & down flow. This is bad. Just 2 feet of lift will really reduce you water
flow, I know I tested it. So if all possible keep your water on an even level. With that in mind I tried
many different combinations, where to put the radiator front back side etc. Well the front worked
the best.
REASON 1
There is always colder air at the front bottom of your PC, you need the most temp spread you can
get. ( example 27 degree air hitting 40 degree water = big temp drop) If you place the radiator
in the top like most people, the air has warmed up going through the PC causing a small temp
spread. (Air enters PC at 27 degrees, at top of case air enters radiator at 34 degrees and then
hitting 40 degree water = little drop) Front mounted radiator is more efficient.
REASON 2
With air coming straight in the PC, through the radiator and straight into the PCI cards, agp card etc.
Sure the air may be a bit warmer, but fast warm air does just as good a job as slow cold air.
I have twin 117 cfm 110 volt intake fans + twin 92 mm side fans with fresh cold air right on the agp card.
NOW IS THAT ENOUGH AIR FLOW ?
REASON 3
WELL I have twin 120 mm 105 cfm 115 volt exhaust fans to help suck the bad air out.
Well I bet everyone think this babe is noisy, but not too bad I've got variable fan controls every where.
More on that in just a minute.
NEXT WATER FLOW
Well if you look hard at the image you will see the water direction. If we start at the cold side of the
radiator, which is 5/8" ID. Leaving there going to my water manifold which by design will let the water
flow free around to my chillier if I ever need it too. Up to a special tee. I HAVE NO 90 DEGREE
FLOW RESTRICTING FITTING ON MY SYSTEM ANYWHERE !!!! JUST NICE SWEEPING
FITTING. Heading next to the CPU reduced to 1/2 id hose, and chip set reduced to 3/8. By
restricting the chip set to 3/8 this makes the water go to the larger 1/2 hose to the CPU. But
combining 1/2 & 3/8 hoses will = about the same as my 5/8 id hoses and radiator. This keeps
my mag 700 gph pump really pumping a very high flow. Somewhere about 500 gph. I did try
putting a regulator on the 3/8 line, but found the smaller 3/8 line did just as good as you could
get. No Need to regulate. But the last place the water passes though is the pump, reason being
the mag 7 pump puts out a lot of heat so I let the water take on some more heat here. Now the
water has absorbed the heat from the cpu, chip set, and the pump. Now it can head to the radiator
for cooling.
