Do I need pressure relief valve?

[KhaderKh]

Hi,

 

I recently built my 1st simple open loop water cooling with only the CPU for now, A friend of mine told me that there is a possibility that air with accumulate inside the loop or hot water will expand or blow the loop or whatever physics will do. 

 

Getting the valve in my country is hard, I need to order it thru Amazon and take many days, so it important?

 

I have EK S360 Classic kit.

 

thanks,

No you don't need a pressure relief valve.

Your reservoir takes care of that, leaving room for the water to expand and contract as the system heats and cools.

Otherwise you won’t ever see pressure high enough in a conventional loop to really be any concern.

since that is a soft tube kit, there really is no risk whatsoever. even if your reservoir is filled to the very top with no room for the fluid to expand, the tubes can still expand.

Not a concern at all. PC water loops will never have enough heat in them to cause a failure in this way. You would need to turn a very large % of the water into water vapor for this to be a concern, and if your loop was that hot, your PC would have overheated and melted itself way long before the water started to boil.

def not a concern your computer will fail LONG before you build up any pressure to be remotely concerned about.

Jayztwocents did a vid a while back where he tested how much pressure different fittings could take before the tube popped out and lets just say that you will never get that much pressure in the loop, especially with soft tube.

I do it one rig. Not only for pressure but for the vacuum produced. Not worried about the other rigs as they dont change pump speed.
