Hello
Instead of buying a kit, i decided to order up my own parts, and make my own water cooling unit. Do you guys think this would be good? Ive got a 1.4 ghz T-bird, in an In-win Q500 case, so thers a lot of lifting.

-DangerDen Maze 2 water block
-A DangerDen "The cooling cube" or aqaustealth "aqaucoil radiator" with a panaflo on it
-a 500 gph bilge pump i have
-and all the other hardware that is neccessary

Would this be a good setup, or do you think i should change my pump? I need all suggestions you guys can give me. Thank you so much

Sounds good....I went with the Cooling Cube myself.

Pump should be fine.

My only suggestion would be to either use a smaller pump or throttle the one you have back a bit. From what I have played with the 'sweet spot' is from about 185gph to the 275gph range. Using the 500 will probably have three drawbacks:

1) The water will be going through your system too fast to adequately cool down (or for that matter collect the heat from the cpu)

2) If water is passing too fast it will cause cavitations in your system (tiny air pockets in areas of restricted water flow)

3) You will need to insure that your system is up to the high pressure that you will be subjecting it to ... that means setting up your system outside of the box and running it for a day or two ... with several start and stop routines in order to check and make sure that it will stay water tight

Hope this helps

i would recommend the black ice, its very effiecient, small and works better than the dd cube

I am looking into whipping up my own water cooled system... any links that you guys could thow at me would be greatly appreciated! Gotta study up on the subject before I can master it. :)

the cube radiator will work just fine. That pump should work fine, but you should ask colin. He uses a 700gph pump, but he is also pumping up six or seven feet.

A very good answer, indeed! You must be a very clever and experienced guy!

Thank you. I have spent 10 years working on liquid pumps in pool setups, from 12gph feed pumps to 50,000+gph circulation pumps. When I found out that I could use that to make my computer go faster ..... hmmmm bonus!!!

Back to the above. I looked a little deeper into the specific setup listed above. Over simplified it boils down to the tube size being using. The Maze2 comes with 3/8" and 1/2" fittings. The kit from DangerDen comes with either a 158gph or a 317gph [email protected] of lift. As a rule of thumb it seems wise to start somewhere around that range and work either up or down to find the right speed for a particular setup. However, overclocking is about ignoring such suggested specs and 500gph sounds like fun.

Depending on the pump manufacturer, the GPH quoted verses real world perfromance differs. I have found a Danner Mag 7 to be optimum with the Maze series and the Cooling Cube. I am sure the guys at Danger Den did their homework before recommending the Eheims they sell. I suspect your 500 GPH pump will be fine. Try restricting the flow with a hose clamp. If your temps go up, you know you don't have too much pump and may need more.

Yep, due to the small fittings and flow restrictions you will get *much* less throughput than the pump's rating would suggest. What you want is to balance the flow considering the surface area of your radiator and the quality of your water block. Basically, faster flow is better at removing heat from your cpu, since heat transfers faster with a bigger temperature differential. But, if the water flows too fast through the radiator it won't have time to cool properly before being pumped back to the water block. So the optimal pump pressure depends upon which block you use, how hot your cpu is, how much restriction your system has, and the size of your radiator and how much air is flowing through it.

I recommend getting a powerful pump because you can always throttle back the flow with an inline valve, but you can't make a small pump pump harder.
