First Loop

post #1 of 7
Thread Starter 
Hello guys.

So at some point I am planning on piecing together a water cooling loop for my comp.


Below is a rough idea of what I had in mind.




The case is the Thermaltake level 10 GT. With blocks on the GPU and CPU I know I need bigger then a 240 rad but the top only has room for a 240. So decided would make sense to take all exhaust points and place the rads there. The order of the loop is Res -> Pump -> GPU -> 140mm rad -> CPU -> 240mm rad -> res.
IF you guys have any ideas or suggestions on how to optimize this especially with the fans let me know.

Once I start gathering the parts can just turn this into a build log.

How about turning the top 240 rad as an intake?

No additional front panel intake? Positive pressure keeps your case from sucking in dust from every nook and cranny.

And Making the top rad as intake would work against convection, and be less efficient, heat rises.

What you have looks good. The 200mm fan on the side providing intake directly to the radiators.

Nope, Thermaltake Level 10 GT case only has that one front panel intake fan positioned right at the HD bays.

Only way to get more air intake from the front panel would be to install bay fan accessories.

Then what you have is fine, I suggest something with decent static pressure if you're going you push air through the drive cage.

I was going to say the opposite... leave the top as an outtake, but turn the back one into an intake... it will still maintain the positive internal pressure while letting the air naturally rise too...

or maybe you throw a 120mm rad on the bottom. you can prolly fit a 80mm one there right? and have that bottom be the only outtake. flip the top one to be an intake, and eliminate the rear fan / rear rad altogether? my thoughts is this will make a straight airflow pattern to avoid pockets of stagnant air. and you'll still have that positive pressure....

Just some other Ideas... Not sure which is technically best...

Bottom of the case only has room for a 120mm fan. I was thinking at one point putting a 120mm rad there as intake. Also I was mistaken, the front fan is 200mm not 140mm.

For the positive vs negative pressure idea I am thinking these Thermaltake cases are designed for negative pressure (though I haven't done the math to figure out if I have negative or positive in this case yet). First iteration of this rig was the Level 10 GTS case and I noticed quieter and better cooling with a negative setup. One reason I think it is negative pressure system is all the meshed vent points which would make more sense in being used to draw cool air in then as exhaust points (simply by location). Doing the hand lick test I can't make a discernible detection on the airflow.



Picture is from Newegg showing basic case flow. Original setup has a 2 x 200mm intake fans (Front and side) as well as a 120mm intake bottom. The other is a 200mm top exhaust with 140mm exhaust. With my current cooling system I have a 240mm rad at top set as exhaust. The biggest problem I have is I can't get numbers for CFM to make the determination as to what the innate case pressure is designed to be. As just the size and direction of the fans isn't enough to make that determination (i.e. the exhaust fans could push more air then the intake fans).

With the negative pressure I didn't have much of a dust problem inside the case. Did have to clean the meshes every so often or else I would lose cooling capabilities but it is rather easy with this case.

I know the one benefit of negative pressure is there would be no static air pockets which can form under positive pressure.
