Is there a point where you SHOULD have two loops, am i at it?

post #1 of 4
Thread Starter 
Im going to be switching over to a mountainmods case shortly and my watercooling is going to be changing along with it so i was wondering if there becomes a point if you really need to run 2 loops and if so am i at it. I would rather not run 2 loops if i dont have to, but will if needed.

Right now its my 2 6970LCS (powercolor with ek block), Apogee XT on my i7, MCP35X, Black Ice Stealth 360 and my frozenq T-virus lookin res.

I will be adding a third 6970LCS, a Black Ice 360 GTX and switching the res out for a dual 5 1/4" bay res. I Might** add a mobo block to my new Rampage III extreme but i have not decided yet.

So do you think my MCP35X will be able to handle it all?

The 35x is the best single pump out w/o going crazy highend. It can handle your setup for sure. But do you have enough rad for the temps you desire? You might want more rad?

Adding another GPU block will actually lower the resistance of the loop (I assume you have them set up in parallel)

And as said before, adding another rad would be fine on that pump. Even then, you would be better off with 2 pumps in series (will double the operating pressure) as opposed to two loops since you will be able to dump heat from both rads which is more effective when you're not stressing everything at once, which you rarely will be.

You don't need two loops. It's all just preference. Mine runs great on a single loop with 8 blocks and 5 rads with 2 mcp 355 pumps connected by a dual top. I used 1 for a while but wanted redundancy. The 35x is more powerful so u have no worries. Check my worklog if you have any concerns
