Just a simple question with not such a simple answer.
I am using about 2 metres of braided PVC tubing, and i currently have a Danner Supreme 5 pump (500 GPH). I'm going to give this one to my friend, and purchase another pump for my setup, only... i don't know if i should get one Danner Model 5 500GPH pump, or two Danner Model 2 250GPH pumps. I have a DangerDen Maze2-2 waterblock, a BeCooling AquaCoil2 Radiator, and a DangerDen CoolingCube Radiator in the secondary loop that just cools and dumps water into the reservoir, and cools the chipset, and GPU waterblocks , and a HeaterCore in the main loop that cools the CPU. I guess the 2 smaller pumps will provide lower noise, but will they yield a higher/lower net flow? Which would you guys recommend? Thanks!! . |
what is the pump in the secondary loop? I'd use a 350gph or something on the primary loop, and a smaller 250gph or similar on the secondary loop
|
The pump to the secondary loop is the a 250 GPH pump.
I'm going to use the new pump(s) i purchase on the main loop. I just want to know what the difference would be between 2 - 250GPH pumps, and 1 - 500GPH pump on the main loop. the way i'll set it up the main loop is: With ONE 500GPH pump: pump -> heatercore -> cpu -> reservoir With TWO 250GPH pumps: pump -> heatercore -> cpu -> pump -> reservoir I guess my main motivation for having the 2 smaller pumps is the lower noise level, versus the 1 larger pump. Thanks for the help |
but then you have 3 pumps total in your system. I'd just run 1x 500gph in the main loop, and a 250gph in the secondary
|
If I were to have 2 pumps I'd have one for input on the reservoir and one for output... but that's just me.
|
Thanks for the help. I guess I'll keep my setup the way it's been, but how about this scenario?
Ok, my friend has 2 DangerDen CoolingCube radiatiors, and a reservoir. Should he go with just 1 500GPH pump, or 2 250GPH pumps. The way he plans of setting it up is: With 1 500GPH pump: pump -> radiator -> block -> radiator -> reservior With 2 250GPH pumps: pump -> radiator -> block -> pump -> radiator -> reservoir What would provide better cooling, or.. what are the pros and cons of each setup? Thanks again! merc |
Ignoring the pump part - my view
He would get better temps putting the two radiators in parallel. Lower back pressure, higher flow, longer time in the radiators.
Single pump - hook the output of the waterblock to the res, output of the res to the pump, the output of the pump to a Y connector, each rad's input to one of the Y outputs, the outputs of the rads into another Y, output of the Y to the block. If he were to use 2 pumps, then you could eliminate one Y and plumb the two pumps into the res. In general, hottest water into the radiator(s), coolest water into the block (remember, a pump will add heat to the water). This is really a case where an air trap/res (like the one Turbokeu made for example) would work better. Then the res could be put at the output to the rads, elimating a Y and keeping the hottest water going into the rads and coolest water into the block. (it would go block, pump, rad(s), res, block again) |
Oh! Great! Thank you so much EMC2!
So, if he were to follow your plans, should he stick with 2 250GPH pumps or 1 500GPH pump? Thanks again! |

Overall, flow rate may increase slightly, but the flow rate through each rad will be halved, and lower flow rate = less heat transfer (less turbulance). And the water spends the same amount of time in the rad(s) no matter what the flow rate is. With a lower flow rate it stays in the rad longer, but doesn't come back to the rad as often.
