Pump setup for cpu+gpu loop

[scutzi128]

Hello I will be building a loop in a few weeks and I wanted to know what I should do for my pump setup. I will be running an ek supreme hf cpu block to cool a 920 i7 and 2 x gtx470 aquacomputer gpu blocks. For rads I willl be running a xspc rx360 rad and an xspc rx120 rad. My res will be an ek multioption 250ml.

I currently have 2 mcp355s one with a Petras top and one with an xspc acrylic top. I have thought about running the pump in series or parallel but I'm not sure if that is necessary. Would one pump be sufficient?

Thanks for any suggestions I appreciate it.

Edit: Oops this should have been in the water cooling sub-forum. Could a mod please move it for me? Thanks.

What are the specs on the MCP355 (head and flow)? I think with only those 3 blocks in the loop, you'll want to keep a careful eye on coolant temperature and flow rate. I would suggest finding a single pump rather than 2 in series (series boosts head, parallel boost flow rate). Splitting the flow evenly also brings in additional problems.

I think 20ish ft of head on the 355.

Well if you can run multiple loops off of your reservoir, I would do the xspc top 355 running the the gpu into the 360. Then do the petra top one running cpu into the 120.

Now if you only want one loop then just use the xspc top pump. The 355 have plenty of flow and head pressure to run the loop.

Id like to run only 1 loop. I figured 1 355 was good enough but I wanted to make sure. I am thinking that I will try running some flow tests with all the blocks installed with a single pump, the pumps in series and the pumps in parallel and see how everything compares.
