build me a loop - Page 3

post #21 of 26
RX *edit sorry* 240 + RX 120 should be fine for that loop. Not the LOWEST temps in the world, but still very good.

MCP355, MCP655, or MCP35x should all do the trick. You can save some money if you go with the 355 and get a Res-Top combination rather than separate Res and Top.

I prefer the look of Acetal top blocks, but acrylic should be fine. The water in your loop won't get nearly hot enough to do anything to the acrylic. The only thing might be QC issues from the factory, but that can be a problem with any product...

What is the goal of your watercooling setup? I believe this should always be asked first. If your goal is silence, then get more radiators. If your goal is better cooling regardless of noise, then you can likely get away with a 360 radiator with good fans (not even necessarily loud, just good).

On my setup, adding an overclocked 6950 2gb only increased the temperature of the water in the loop 1 degree celcius or so versus just GPU. Some of the reason that this impact is so low is the quality of my radiator, flow rate, etc. I would argue that your system can be run easily on a 360 radiator, your fans might not be as quiet or low speed as you like, but it can be done. Just get a PWM controlled controller (Sunbeamtech Rheosmart 6) and set a custom fan curve/profile on your mobo's software suite, and then it'll run the fans silently when you're not loading your CPU/GPUs, and when they are loaded, the fans will spin up, but you're probably gaming or busy doing something at that point, so you won't care or notice. That's how I run my loop, and I believe that's how a gamers loop should be run.

I will be using 2200 rpm fans. Ive got 6 cm blademasters that will be used for this. My overall goal is good temps. I have a fan controller, so I can turn the fans down when everything is idle.

so guys, what would be the ideal pump for this setup. 1 cpu block, 2 gpu block, 1 360 rad, and possible a 120 rad. I dont want to spend too much on a pump that is overkill for a system like this.

What would be just right?

is 22psi enough pressure for aloop like this? i wish i could find the specs on the x2o pump so i had something to compare with.

I would say a Swiftech MCP-355X pump will be plenty sufficient.

As for the top of the card blocks, I prefer acetal vs. acrylic. Acetal is the black (or white) plastic that is used. It's a little more expensive, but is more stable than acrylic, and can also be used with more chemicals without worry of cracking (acrylic will not handle alcohol additives). Over time I've also heard of acrylic leaking.

What GPU blocks are you looking at? I've had a Swiftech 5850 Komodo, and EK 6970 block...the EK is much superior, in terms of build quality, as well as cooling and flow performance.

they are ek blocks with acrylic tops. They were the cheapest ones frozencpu had for my cards.
