Reservoir Placement Questions

post #1 of 6
Thread Starter 
I am in the process of changing around my loop (yet again) from the XSPC dual bay res and pump to a 655-B + ek v2.0 top.


Question 1: Does the reservoir have to be above the pump? Does the answer to this queston change if the radiator is the highest item in the case?


Question 2: How much restriction does a reservoir add to a loop? Would it be better to have 1 reservoir or 2?


I will have is where to install the pump within a coolermaster cosmos (1st edition) with a RS360 on top and a RS240 in the rear? My enermax 1000watt PSU takes up almost the entire space and the bottom only allows room for one intake fan. And there lies all my problem which has prompted all of these questions!


Messing around with watercooling is so much fun yet we choose to test ourselves with no space. I feel like I am erecting a battleship in a beer bottle....

ya the res has to be above/level with the pump because it is gravity fed. one res is plenty, you actually don't even need a res, (a t-line will work)they are used mainly for the convenience.

You only need one reservoir, and yes, it should be above the pump. It doesn't matter much were the other components are, but bleeding can be more difficult as a result.

I don't have any good ideas regarding loop layout. My advice is to take a good look at the case and do some brainstorming.

The water level should be above the pump inlet. It does not have to be by much, just so long as the water will naturally flow into the pump inlet

Quite a lot. Basically the flow looses it's momentum and slows right down, then has to be sped up as it hits the exhaust port to maintain the same flow rate. I would stick with one res, before the pump and at the end of the loop.

I was wondering about this for a while earlier. I halfway thought it would be minimal because the water was being pulled out as it was pushed in... it seems gravity/pressure would naturally help force water out of the reservoir.
