Hi, If I were to have two 240mm rads (about 3-4cm each) and a CPU + dual GPU waterblock loop, what flow rate pump would you recommend? Ta!
Anything like an MCP350 or better within sanity should be just fine. Unless you are planning on using huge lengths of super thin tubing it's not going to be restrictive enough that you need anything super high powered in my opinion. Though, also with that I might be tempted to run 2 loops. One for the GPUs and one for CPU. Since you can probably get 2 less expensive pumps that would be perfectly fine instead of one more expensive higher powered pump.
Nice one, I've got a spare 400 lph pump knocking around, so I should be able to use that then. It's a very small case with decent cooling, I'll probably keep it to one loop for simplicity. Ta for the advice!
