Head pressure on a Rasa 750 kit

post #1 of 5
Thread Starter 
I was looking at a swiftech edge 320 kit but the price compared to a Rasa 750 360RX kit its a little more then I want to spend. I have all my computers on a rack and want to mount the radiation vertically above the case which is a 4U server case and there is no room internally. I am looking at mounting vertically with the top of the radiator being between 2-3 feet above the pump. Will the pump with the rasa kit be strong enough to pump the water up to and through the radiator with only the CPU block? I was thinking going with a single or dual 355 with a XPSC reservoir.

xspc x20-750 pump has 1.8m of pressure

mcp355 has 4.5m

the DDC is more appropriate for a restrictive multi block loop. if your only doing a cpu and maybe a gpu or two, the x20-750 will be ok.

Actually its just a CPU.

It has 3.69 PSI of head pressure @ 1 GPM of flow.

So a little over 1/2 of the head pressure of a 355 + Top. That's some excellent performance considering the 355 can easily push through 6+ blocks and multiple radiators.

Keep in mind that a higher head pressure might be more appropriate for a rather restrictive loop, however that fact stands in absolutely no relation to good temps.

Good temps will only be achieved with a pump that provides a high flowrate
The endurance (head pressure)only guarantees the water to encounter less resistance nothing more, so be aware.
