Need a new pump?

post #1 of 9
Thread Starter 
Well I am probably going to pick up a water block for my 7870, just cause, and throw in a 360, 240 rad in a new switch 810. So I was wondering will my xspc rasa 240 kit pump be enough for all that?

For a typical low-restriction CPU, VGA card full-cover, and 2 rads, the XSPC 750 pump will be fine. There are some blocks & rads that are very restrictive so buy low restriction components for best results with that pump. See Martin's Liquid Lab or Skinnee Labs for testing of pressure drop of the component compared to average.

If your flow drops too much and you have trouble bleeding air or even have temperature rises, you can always add a second pump in series. You may want to check Martin's pump/rad optimizer and try to keep flow around 1 gallon per minute or at least over 0.7 gpm. Good luck. smile.gif

you could run the cpu and gpu blocks in parallel and it would reduce the resistance. thats what im planning on with my gpu block once i get it. also when you add the new block check your old block for gunk build up inside.

I don't even run a vga block, and that pump could barely handle my rx360 and rx240 :\


(I switched to an EK reservoir with an mpc655 and my temps dropped around 6-7C)


edit: i need to update my sig rig... so much of that has changed, haha

I think that you would be much better off in the long run with an MCP35X or MCP655, but if money is an issue then the XSPC pump could keep you going until you had the $85 for the (vastly) better pump.

Adding a second pump in the loop could be an option as well. If the case has limited room a DDC size will do the job well.

Yea I figured I would get the mcp655 but if I do should I get the one with a speed control or not. Also which is a good reservoir to go with it?

I honestly think that an MCP35X is a better option, not only is it designed for restrictive loops (which, if you plan on having two Hydrocopper blocks, yours most certainly is), it is also PWM controlled and thus adjusts automatically with no intervention on your part, and also no reaching inside the case to adjust it. Even better, it will always run at the lowest necessary level unless you configure it differently, which means QUIET during normal use and will only speed up when you do something intensive. Seriously awesome pumps, and very small. Some prefer the D5, but the MCP35X is the absolute best IN MY OPINION.
