Little frustrated, need some advice - Page 4

post #31 of 34
I got it all figured out, this not my first rodeo.
7 blocks, 5 rads, and yes, a single punny koolance D5 vario pump.

Dual loops are not as effective: you have two pumps making twice as much noise and heat. And you dont get the full capability if your rads when you split them between two loops.

For example, let's say you have a cpu loop with a 240 rad, and a VGA loop with also a 240 rad. So you want to encode a video and you OC your CPU to the max. It has that 240 to cool it, but it sure could use that other 240 for help. Unfortunately, it's sitting in the VGA loop barely doing any work while the GPU is idle.
You almost never use both CPU and GPU at the same time, so in dual loops, there is always one rad doing barely any work.
In a single loop, you get the full use of all the rads where and when you need them.

Just watch my build log when I start, you will see a lot of innovations that will make my 7 blocks, 5 rads loop less restrictive then your average 2 blocks loop.

Im even working with a machinist friend to create a cpu block that could very well revolutionize the water cooling business. Stay tuned for my build log.

The D5 pump does add heat to the water, but nothing noticeable. Running at maximum, each pump dumps in about 20 watts; and you're likely not going to be running them on full all the time anyway.
Very, although it'd be a little better if you went Res->Pump->CPU->(VRM & SBridge)->(GPU1 & GPU2)->Rad. There's no reason to run VRM and SBridge in series if you have the option not to; be aware of any difference in restriction between the VRM and SBridge blocks if you do this, though.
The most important thing is air flow. If you can add this rad, give it fresh air, and still have the same amount of fresh air going to the other rads, then go for it.
If your GPU blocks are restrictive (most are) and your overall flow rate is good (1.5gpm+), go parallel. If your GPU blocks are not restrictive (such as danger den) or your overall flow rate is mediocre or poor (<=1gpm), go with series.

I definitely do not have any problem doing CPU -> VRM -> Sbridge but as much as I love this loop to function, I want it to look good too. But that order is going to look horrible since I have to back and forth frown.gif

Since XSPC rad is 120.4 I was thinking to place it on the bottom chamber with the Other Monsta but it has been said that it will be rad sandwiching...

Edit: I guess I will get a 240 Monsta and place it on the flex bay with push pull

When all else fails, practicality over performance. Having an extra 1-2C is likely not worth extra headache.

Well, here is how I plan my loop. Maybe that can give you some ideas:
Double bay res is at the top flex bays.
Below that, res to pump
From pump to 240 rad in flex bays.
From flex bay rad I go parallel to 3 blocks (VRM, Southbridge and CPU).
All those go down to bottom rads in parallel still.
From bottom rads to quad SLI VGA's.
From VGA's to top rads.
And top rads back to res.

Bottom rads pull from floor and exhaust to sides.
Top rads pull from sides and exhausr to roof.
