Hmm I haven't even come to think of that option, the tubing would still look just as good I'll just have to switch the tubing on the pump inlet and pump outlet. Thank you, I'll consider it.

edit: hmm just came to think of the temperature sensor though. With the current design it would read the highest water temperature because of it would be after the blocks. In the new design it would record the lowest because it would be after the RAD. Hmm an other thing to think about I guess. Choices,choices and more choices biggrin.gif.

True about the temp sensors but you could put them almost anywhere in the loop if you wanted to. Also if you use OCCT and have that running in the background it will show gpu and cpu temps and can also show the current voltages. Eventually if you have the temp sensor reading it at the coldest point you will know that part of the loop will read a couple degrees higher than that and your brain will compensate for the difference. smile.gif

In a loop like that, your highest and lowest temps are going to be 1-2C apart, max. The first setup looks just fine. As for just tipping the res, you could do that, but it'd take longer since you'd need to keep air coming in through the same port you're pouring from. A drainline isn't a bad idea by any means, feel free to add one if you think you'll be draining the loop frequently.

I always wondered how these top mounted radiators did when it came to debris falling into the fans (if push/pull) and I think having the heated exhaust air blowing out the top would not be my preference.Are you going for some type of grill to cover up the exhaust area?If I did mount like that I would consider having a bleed petcock put in one of the tanks (but Hey,that is just me).I would plan on using some no drip quick disconnects on the hoses to the radiator as you would not want the contents of the radiator dripping if the loop had to come apart or the radiator had to come out.Figure between 20-25 for both sides of a quick disconnect,and you will need two.

Yeah I guess it won't matter, I didn't realize that the temp difference is that small.

This being my first water cooling setup I think I'll be too paranoid not to drain every ~4 months or so and a T-line seems like a very safe/convenient way to do it.

Would it be safe to screw in a L-piece - G1/4 screw-in - 2x inner- 1x outer thread - black nickel into the pump outlet? The threads look very long to me.

Nice setup you are building there. In my opinion you shouldn't have any problems with the flow rate. The pump you have chosen for this setup should do the job properly. The order of the loop doesn't play much role on the overall performance since the flow will be high enough and the liquid will fast achieves stability (so called steady state regime). I'm also considering to build a similar WC setup and NZXT Switch 810 case is really great for this and offers plenty of room to add an additional radiator if required.
Don't forget to post some pictures when your build is done.

I'm afraid that's not how the flow works if you stop for a second to think about it. You have "X" amount of water going into a tube at the pump so exactly the same amount must come out at the end of the loop or you have leak. Conservation of matter and that kind of stuff.

You are probably meaning the pressure, which does drop as you add restriction to the loop and the flow is a function of pump pressure and restriction of the (whole) loop.

Anyway, what I'm saying is that flow rate does not depend on what order you have the stuff in your loop. It depends only on pump head pressure and combined restriction of the whole loop. X liters per minute goes into the tube at one end and the same X liters per minute must come out at the other end.

I would second dtrunks reply, go from gpu to rad then cpu back to res. That saves the long tubing going from the top of your case to the bottom, making it look better in my opinion.

This. Maybe move your res/pump combo up into the 5.25" bays, and get one of those cross flow radiators... nice clean display that way tongue.gif

As to loop order, irrelevant completely. However it goes together in a way you like is fine. Though, I try to keep the loop as short as possible. As someone else stated, temperature differences are minor, 1-2C, at most.
