Hey guys this is my water cooling idea open for criticism, I just thought the last component in the daisy chain would benefit from this as it wouldn't get the waste heat from the other components in the line. and yes I know that the pump should be between the components and the rad as it might have some waste heat to introduce to the loop but it still illustrates my point.

Here is your problem. Cutting flow in parellel bring up two issues. Which blocks is most restrictive and cutting flow rate in half (if your lucky) can cause temp problems.

Real pros at WC (yes there are such) know flow rate must be above xx or the blocks will not operate properly. Depends on the block, pump etc. It's a science and an art.

Your next problem is how to balance flow rates if you were able to get them high enough. You'll need a few $100 in testing equipment, and even then once you get the number right, every valve, fitting, etc reduces flow rate.

Luckily, I know something. In a standard CPU/GPU loop the water diff ANYWHERE in the loop is no more than 2C different. Seriously. You want pure data from testing gods, I can supply it. Charts and tables out the ying-yang.

You make a easy serial loop with the golden rule of res before pump and shortest tube run. Then you put the CPU before GPU, but really not critical. Get decent stuff, no big deal.

If you would like a few links that will keep you busy learning for at least a week, please ask.

Splitter = fail. Both pipes wont get even flow.

In that pic your gpu will get most of the water and your CPU wont hardly get any.

Here is what i think.

-RES-PUMP-RAD-CPU-GPU-RES---

This way, your water is Refreshed just before going trough your CPU-GPU. With a good flow, good rad, youll see some NICE temp.

I only WC my CPU and my idle is still 30c (22-24c room temp) after 24h non stop. I have a 2x120mm rad. for a GPU it can still be ok but ill recommend a 3x120mm.

You could use two pumps drawing from the same reservoir .
one pumps to the cpu the other to the gpu and the two water flows combine back at the radiator

i ran that setup and there right no flow to the cpu had to redo the tubeing within an hour lol.

Yes, the splitter is a bad idea. This should be the loop:

Radiator-->CPU-->GPU-->Resevoir-->Pump-->Radiator.

Splitter=no flow? Not exactly. The problem is that which ever side of your system provides the least resistance (after the splitter) is going to be the side that flows better. The two parts of your system will not flow (or cool) equally. Alternately, feeding the water through your CPU cooler before it goes to your GPU cooler will raise the temperature of the water reaching the GPU (and lower that cooler's cooling capacity).
Over all, I kind of like that last idea (using two pumps), but it seems overly complicated. Alternately, flow gauges could be placed before the CPU and GPU coolers to assure adequate flow is reaching both.

As said before go with a single loop or add a second pump for two loops.

thanks for the input guys. it makes sense that that which ever one was higher than the other would get less feed.

i did read up on blocks though. how bout this, I dont know if its a good idea or not for the gpu but what if the gpu had an impingment block, not allowing as much flow through to the bottom half of the loop, thus in theory the excess water pressure would force more flow to the top half of the loop. I figured that since most gpu's are single core and have, i assume, only one hotspot on the core that that type of block wouldn't be a bad idea.

or you could have the full flow going to your cpu then ure gfx card as gfx cards dont put out much heat they can run alot hotter.

YUP .. stick with -RES-PUMP-RAD-CPU-GPU-RES- as I and others said.

You GPU will still run cooler than she was. With 1/2 tubing and nice flow the water dont raise that much from going trough the CPU.

That might not be a brilliant plan since high performance gpu's use more power and release more heat than top end cpu's .

[ since gpu's are larger and more complex and much more expensive to make its pretty obvious that intel and amd charge WAY too much for cpu's ]

The double pump idea is still the best way of feeding the coolest fluid to both water blocks

+1 for RES-PUMP-RAD-CPU-GPU-RES.

Btw, what are the specs?

Here ya go Phil. Spend a few days, you won't have to ask these questions.

Take your time to learn while you wait. I wrote this a while back, it will help get you on the right track.
............................................
For your benefit please spend a few days reading a LOT. Here and at the busiest places for WC masters. Guys who have done it for YEARS at OC forums and xtreme forums. It took me a while (I was OCing on air, aftermarket stuff, bios settings, best chipsets etc etc) to learn the language and the tricks to a easy install.

Don't expect miracles, or SUPER DOOPER over clocks. What you will get is a quiet system that can handle OC to the max of your hardware IF you buy quality and buy smart. And minor maintenance too, a bonus for the water cooler.

Also while there please read on case mods etc. The radiators are not for small cases, the pumps and hose routing, wire management and other things are important to understand. Google your planned case and the word water-cooled in one line. You might get lucky.

IF you just cool your CPU and your NB if you want, you can get by with a 120.2 sized radiator (RAD). And MAYBE fit in inside depending on your mod skillz. You want to cool your GPU too, you'll need a 120.3 sized rad, and it won't fit inside. The rear external rad really works great. No matter what your adding 15lbs to your PC, maybe 20lbs.

Once you got an idea of what is good/bad then start getting your system for WC put together and we'll be glad to help.
