Not sure I would trust any parts that cheap around my computer lol especially not any 3D printed parts. For reference I had an EK Supremacy block, but I did use a submersible pond pump. Make sure you get one with adequate head pressure.

I ran PT Nuke in my fish tank res and it worked fine. My biggest issue I ran into was lower cooling efficiency (see: hot-ass room due to the AC being broken) in the summer, and a huge amount of dust getting in the loop after I added some glass rocks to the tank for aesthetics. It would have been just fine if I had considered even just rinsing the glass before adding it to my tank. I think there's a video near the end of the thread linked above.

Edit: Having scrolled up through the thread a bit, I would like to add that a majority of my cooling performance came from the water being exposed to moving air (it was next to a window that I usually kept open) and from evaporation of the water. You will get natural evaporation over time, even of the water isn't "warm". I usually refilled with distilled water to keep everything clean and free of minerals. There will be some amount of radiation through the glass, but it won't be much, especially if the delta between the water temperature and the air temperature isn't that high. What's described in the posts above is more of a thermal capacitor. It will absorb the heat and keep the CPU cool but it won't do much to dissipate that heat into the air.

Hi everyone,
 
I'm new here and ready to make an ass out of myself. I've been interested in water cooling for a while, opting to go with an AIO Corsair unit in the interest of budget and safety. After watching some water cooling videos on LTT, specifically the whole-room water cooling, oil cooling, and scrapyard water cooling videos, some gears started turning in my head. My computer doesn't run hot but it is a bit loud and if I can make it quiet and cooler all in one go, all the better.
 
My solution is using an aquarium as a passively cooled radiator/reservoir combo, the idea being that the surface area of the water would dissipate heat without the need for fans or a separate radiator. I know that it wouldn't be nearly as efficient as an actively cooled system but my goal was for perfect silence and as few moving parts as possible. Following the information in the Watercooling 101 sticky thread and doing some of my own research and number crunching I came up with the following:

To calculate the number of hours it would take to heat the water in the tank you have 3.1 * Gal * ∆F / TDP = Hrs where Gal is the volume of water in gallons, ∆F is the temperature change in Fahrenheit, TDP is the heat generated by the parts being cooled, and Hrs is the number of hours it would take to reach the target change. The first stage of this project would be to just cool the CPU, which is rated at 140W TDP but the goal is to cool the CPU and both GPUs, which is a total TDP of ~440W. (Note: I would be running a submerged pump to reduce noise and haven't taken the pump's TDP into account) To find the right balance of tank size and time the system could be effectively cooled I plugged in the variables and came out with this chart:

(Temperature delta in F, results in hours)
 
30 degrees F is my baseline (100F/37.8C target - 70F estimated room temperature) with 50 being the upper limit (which would put the water at 120F/48C. I haven't seen any data comparing coolant temperature to CPU/CPU temperature, and I doubt it's 1:1, but 120F seems like a reasonable limit. So now that we have values for everything else we need to decide now long we want to keep the system at full load before hitting these temperature targets which will tell us our tank size. Looking at the 30 and 50 degree rows the 10 gallon column appears to give the best times for my typical usage, 2.1 hours and 3.5 hours respectively.
 
Another variable, which will either depend on or determine the outer diameter of the tank is heat loss due to evaporation and radiation which is dependent on the surface area of the water. One tank I'm looking at is cylinder with a surface area of 1.07 sq ft. Using this chart as reference we get a BTU/hr loss of 230 which translates to 67.4 watts/hr when the water is at my 100F target and 137 watts at my 120F target. It's not going to dissipate the whole 440w load but it will slow the rate at which the water warms, and it also assumes there's no air moving across the water so the efficiency could be a little higher. If I need to increase the amount of heat being shed I could also run a standard radiator mounted to the top of the PC.
 
Like I said, I would be starting with just cooling the CPU which is only 140W. The chart for that looks like this:

(Temperature delta in F, results in hours)
 
6.6 and 11.1 hours at full load, not taking the natural cooling of the water into account, is certainly doable.
 
With all of that out of the way, does anyone see a reason this wouldn't work? The main issue I see right now is finding a submersible pump that will supply enough flow without adding too much heat to the water.

I will be writing the awards ceremony this afternoon, it is currently 1030 here so expect it in the next 12 hours or so. 
 
I'm still trying to work out the best way to deal with 250+ prizes, as in distribution. I will probably do what I always do and ask people to DM me. 
 
EDIT: No idea where I got 700+ from, thats what I get for not paying attention!
 
Can't wait for a nice break

And that is a wrap people.... The event is officially....
 
 
DONE!!!!!!
 
 
Thank you to everyone who has joined in, you guys have really made it special and I hope that you all keep up the fold, even if it is a little more muted! 
 
Now it's time to pour a drink!

Me, yesterday: Ooh, I'm on track to get a million points!
F@H:

If F@H gets the new Linus and 2 New Azure Work Servers running soon we should all be well-fed

I feel like this trend is going to continue the more and more folders join the fight lol

I think I have thrown some points in, I think I do about 10k points a day on the PC in my sig, folding while the sun shines on the solar panels anyways.

Adding another one to the mix. This i7 + 1060 normally live in a Pelican case, but in the off-chance it manages to get 100% usage on CPU+GPU I decided to take it out for more cooling. That makes the total 1x Ryzen 1700, 1x i7 7700, 2x i9 7800X, 1x 1080ti, and 3x 1060s. Let's hope those WUs keep following.

It's not; the side that the hub is mounted to should be the exhaust side. The fan is there to help feed the GPU and create positive pressure to push the warm air out (it makes sense if you could see the system in the case).

Same, but since they're already having a hard time keeping up with the amount of systems ready to work, it's probably for the best so otherwise-idle time gets used for good.

I'm folding on all available slots! 
Must have the servers upgraded now.
Man, this room is getting hot...

So I rebuilt a workstation to run F@H at work, along side my main workstation, but once I got the system together I couldn't find and PCIe power cables 😭 so I dropped a 1030 in and set it to run only on the CPU, and took the 1060 that was supposed to go in there and put it in my main workstation. 💪 But the spacing between them was kind of non-existent, so I unmounted the power supply and installed the GPU one slot down (and it has more bandwidth now). Still working on ways to allocate more resources.

The first photo showed the problem (no gap between the cards). Second photo shows the gap, and the fact that I had to unmount the PSU to make room for it. 🤘 Good looking out, though.
 
Edit: Oof, setting up the client to recognize both cards was a little scary lol. Once I figured it out it was pretty simple.
