Considering a unique no-loop system

[ibble]

I've seen it in use before but have no idea what to call it. Essentially, I would like to do a watercooling system where water enters, goes through a CPU block and then exits to a drain or into a basin where it can be recycled. There is no reservoir or radiator involved, just the flow of cold water through the blocks. My question: Is it practical and what kind of performance can I expect?

 

My input source is a 1/2" copper line at 40 pounds pressure, unknown flow rate. Water is approximately 21.5 degrees Celsius. I would like to have it enter my case, run through the CPU block and run back out of my case. Afterwards, the water will go into the inlet of my water heater, so it can be reused. Will I experience a buildup of material in my blocks due to the fact that the water is softened and therefore has brine-like qualities?

 

I would like to use the Summit EF waterblock with Acrylic top to view flow.

The amount of issues from using tap water and also the wastage of pouring clean water down the drain (and the cost) makes this pretty pointless/wasteful

It will recirc into the inlet of the hot water heater as mentioned above. What issues arise from the use of tap water?

It's not clean, limescale and other minerals will destroy whatever you have it running through pretty quickly. It would be a much better investment for you to just get an AiO if you only want CPU cooling.

whenever your hot water tank is full you will have 0 flow rate. also, you will have all of the metals in your houses water system connected to your cpu block with unfiltered (conductive) tap water. that is a recipe for a disaster. dissimilar metals in a loop create an electrolytic reaction.

Doooont do it

First straight tap water has it's issues with minerals and other things in it etc, but also the fact that it's an open loop you have to keep it sealed and with a biocide in it to prevent bacterial growth in the water. There's a reason why distilled water is used and not tap water. 

 

With your concept of just flowing water through it won't dissipate heat in an effective manner just storing it in the water, it will eventually overheat if you apply too much of a load with no way to remove the heat from the fluid.
