Liquid cooling q- flow and rads
Maybe an MCB plumber could chime in here, wink wink...
Hello all! I am going to expand my simple liquid cooling system for my PC. I currently have a "Silent Water" by Thermaltake. Cute, and about as potent as any very high end air system. It is comprised of a 120mm radiator, tiny resevoir, 72 l/hr pump (I think), and 1/4" rubber lines.
I will be expanding soon:
Tripple 120mm radiator (butt-mounted)
Double 5.25" bay resevoir
Transparent blue UV responsive 1/4" (8mm) tubing
My question is about flow and the order along which components should be installed. I will be keeping the old pump/res/rad setup.
From the pump:
Should the water go to both radiators sequentially before or after the processor?
Should the water go to one radiator before the processor and one after?
At what point in the flow chart should the water go to the bay resevoir (keep in mind it will be the highest elevated point)?
I like sloshy and drippy noises, by the way. If we can do that without getting bubbles stuck in the processor water block, I'm happy.
Thanks for taking the time!

Not an expert but here's my 10 cents...
If you are using a liquid cooling system I assume you need to dissipate more heat than the average person so I would guess you want to maximise the efficiency of the cooling system.
You will get the most efficient cooling with the greatest difference in temperature between what you want to cool (the water in the radiators) and the environment (the air around the radiators).
If you have two radiators the best way to set them up would be in parrallel after the water has absorbed all the heat from inside the case.
If you put them one after the other (in series or as would be that case if you put one before and one after the reservoir) the second radiator would be receiving water at a lower temp than the first and would be operating at lower efficiency.

I've been out of the product loop for H2O cooling for a while, but my main rig has been through 3 systems, and has been running strong for a while with 1 major incident.
On that last part, I will tell you this.. use no plastic waterblocks. The danger den ones with the thick acrylic should be good, but other than that, be careful.
To answer your questions:
I would go - CPU -> GPU -> Northbridge -> hard drives -> Reservoir -> pump -> Rad
For best performance, I would not mount the radiator on the back of the case, you are just pushing hot air through it later. That is, unless you are watercooling almost all the major components, but things like hard drives and big fast mobo's make heat. My setup has it's own case for the rad, pump, and reservoir.
The rest of the system can handle a little heat, don't worry about cooling right after the CPU. You would probably loose performance by the runs and flow drop that you get from the rad. (and on that, flow meters are useless and hurt performance)
My take on resivoirs... make your own. Unless you need fancy stuff, make your own out of some good thick plastic container, some hardware store barbs and some length of hose. Make sure there is enough space so your water return doesnt splash and push bubbles into the intake, and decrease performance and make noise.
Honestly, I think the bay reservoirs are nuts. Put your water supply down low where if it leaks you don't kill much. Hard drives don't like water. Everything else can stand a little moisture if it leaks.
Pressure and flow are your friends. 1/2 inch tubing and barbs are your friends as well. I'm still running a 10mm CPU block on a 1/2" system, but it runs well enough.
Check overclockers.com for recommendations on hardware. I used to just lurk there and be about the same level at Tom's Hardware as I am here (posted for a long time under Lonemagi). If you got any questions, shoot me a PM and good luck!

I remember somebody somewhere did a water cooling tower that was pretty cool, and would get the bubbling you like.
Basically, you take a tube, say 5" PVC, and you leave the top open. make sure the tube could contain the entire volume of the water in the system in case of a clog or problem.
Now, run the hot water up to the top of the tower and out of a showerhead - the closer to mist the better. Use the bottom of the tower as your resevoir. The falling water will cool very effectively and you can easily keep plenty of water in it to keep the pump from going dry.

That would look wonderful in clear acryllic Though I'm trying to keep the system portable. Thanks for the input so far!

That would be a "bong" cooler setup. They are OK, but in this day and age, cant keep up with a good high pressure setup like the ones from DangerDen.
Biggest prob with watercooling is the lack of portability and the price.
