General questions about the STH10 case concerning watercooling and case layout

post #1 of 5
Thread Starter 
Which loop (in a 2 loop system) would be most prioritied, a loop for the GPU or a loop for CPU+RAM? Lets say I use 2x 240rads for one loop and 2x 480rads for the other. Does one develop alot more heat normally then the others? Or does that depend on what part of the system you presure? Would the best choise be to have all the rads connected too eachover perhaps and only run one loop?

Is a two loop system only for aesthetics or do you gain anything in performance of having 2 loops? What are the pros/cons of the diffrent styles?


Imagine there was this layout in the top compartment, from left to right; 25mmfan, 64mmrad, 38mmfan, 13mm open space, 38mmfan, 64mmrad, 25mmfan. The thought is having the 38mm fans connected to a fancontroller and the fans would normally be inactive and only used when clocking or pushing the system. My questions is would the inactive 38mm fans disrupt the airflow genereted by the 2x 25mm fans that push and pulls fan through the radiators? The airflow would enter from one side of the case and exit the other. The other questions is would having fans so close to eachover on the inside of the rads be a bad thing? I'm thinking that if there is no gap in between the rads and fans that the hole setup would work as a tunnel for the air, so that no amount of air the fans pushed would go anywhere but strait through tha rads, is that assumption wrong?


Which side is the midplate-fans attached to? If you have rads for 120mm fans in both the top- and bottom compartments, could the midplate-fans still be attached under the low midplate and over the high midplate? Would the psu in the top or bottom be a hindrance? In the pictures it seems to be plenty of room over the bottom slots for the psu so that I 25.4mm thick fan would fit? Not so sure about under the top psu, there it seems to be less room there.


Or would they have to be attached on the other side so you would be able to see them through the sidepanel window? As far as I know the bottom compartment is a tad bigger then the top one. So having fans under the bottom midplate might work, but not over the top midplate because of the smaller size of the top compartment? And still being able to fit psu and rads ofcourse.

could do 2x 240 for cpu + mem + mobo, more than enough and 2x480 for GPU. Then you can most likely cool 3 GPU's.

You could also mix it a bit, one 240 + one 480 for cpu, and the 240+480 for GPU's but then you might have to watch out with a 3-card setup (also depends a lot on the gpu's being used).

I am going to be very candid. When I first read your post, I was not sure if you were talking about a case lab STH10 or someother STH10 altogether. (Make sure you are still looking at a STH10 and not TH10.)

Here are some build logs to get you started and thinking straight:

http://www.overclock.net/t/1284822/sth10-build-log-a-water-cooling-noobs-diary

The first is very detailed and one of my favorite build logs due to the depth and breadth of its content
The second is very good too
The third is a great newbie guide as the title suggests

Answer to some of your questions, in no particular order:
- Stay away from dual loop. Its not not aesthetically pleasing, in fact it is aesthetically unpleasing
- Kick the 240s to the curb and leave them to die in whatever case they were before. Sth10 is not the case for 240. You should be looking at 560s
or 480s in the bottom compartment, a 480 in the top chamber with a slim 360 (to give your PSU room for multiple PCIE connects, etc).
- If you are water cooing, airflow ain't gonna matter much, as there will not be too much heat exhausted in to the case by stock gpu coolers. Get
good rad fans. I recommend Ap15s or Cougars.
- A bit perplexed about your middle plate fan question, and that generally goes for all of your fan and plate related questions. Yo won't be putting
a fan or a rad on mid plate or top plate. You can add case fans to the front and one on the back. Generally speaking, if you don't go overboard
with bay devices, you can put three intake fans on the front, and one exhaust towards the back.

If you need more info, feel free to pm me.

Why only 3 GPU's? why not 4? would I need more than 2x 480 rads to cool a 4-way sli setup? And why would I have to watch out with using 3 GPU's if a mixed the rads? (240+480 in each loop). Sry for the noobish questions smile.gif

well, unless you're doing compute, a 4th GPU really doesn't add all that much (for gaming). So that is why I went up to 3 GPU's in the example and not 4 smile.gif
