Ok. Not sure if this is the correct place to post this, but here goes. I have an idea to make a liquid cooling system for my GPU, but the same would be applicable for my CPU. It is fairly simple and also cheap. Prices and requirements as follows.

1/2-in x 100-ft Polyethylene Polyethylene Tubing: $24.96
ATP Surethane Polyurethane Plastic Tubing, Red, 1/16" ID x 1/8" OD, 100 feet Length: $9.28
Aleene's Rapid Dry Mixed-Media Adhesive: $9.19
Silicone II 2.8 oz. Clear Kitchen and Bath Caulk $3.98 (for tube conversion as there are no 1/16th converters)
Small custom bracket using https://www.onlinemetals.com/ whatever metal you would prefer. preferably something thin and pliable that you can easily drill bend and mold to your needs.

We have a couple options after this.

Liquid Nitrogen (really Removed expensive, but cold as.... well Liquid Nitrogen) with a boiling point of (−195.79 °C (77 K; −320 °F)) and a freezing point of 63 K (−210 °C; −346 °F) were talkin a frigid GPU/CPU that would be incapable of overheating. Could clock to 50k MGHz and still be freezing (if such things were possible). a container of liquid Nitrogen costs $300 and $5 per Liter up to 10 Liters.
Pumps are.... well look for yourself. https://dir.indiamart.com/impcat/liquid-nitrogen-pump.html
your looking at a really expensive cooling system at this point, but Removed me if it wont keep your things well cooled. Metal Cracking cold.

Now for some realistic options which follow through with homemade and cheap.

VicTsing Upgraded 80 GPH (300L/H, 4W) Submersible Water Pump, 48 Hours Dry Burning Water Pump with 5.9ft $9.99

Now through this pump.

Water in a small bowl or fish tank filled with ICE (this is a circulating system, what goes in comes back again) $7.14 cheap fish bowl. plus costs for running freezer making new ice all the time. Also requires constant supervision and maintenance to ensure all the ice hasn't melted. (could also opt for a mini freezer to keep things frosty.

Vodka. yes Vodka. at a freezing temp of -30C and -22C this a great option for Frigid cooling. Pack this with Ice, put it in a container filled with ICE, put that container in a minifreezer $115.00 and you have yourself a perfect cooling system that will never freeze your pipes. Taaka Vodka $10.99 1.75l

Vehicle coolant also works. $7.98 Super Tech. (boring)

Then there is this conventional cooling pump.

Yosoo 12V DC Low Noise Water pump&pump tank SC-300T for pc CPU Liquid Cooling System $22.04
designed to be used with
Thermaltake Pacific DIY 1000cc Liquid Cooling System Coolant CL-W021-OS00BU-A Blue $15.99

Although nothing wrong with using the above mentioned liquids.

So our cheapest total would be about $70.00+tax using our ice filled water bowl coolant system.

Now for the setup.

Detach GPU or CPU heatsink

we want to pull off our fan cooling system.

Next we want to glue our 1/16" tubing into a coil like this http://www.chicagopipebending.com/images/bends/9flatspiral.gif only no gaps and the spiral meets in the middle and exits through the top.

Now we want to attach our tubes using the caulk 1/2' to 1/16'

Next we want to make our bracket to the required size. This bracket should hold the tube coil in place over the processor using the existing screw holes and screws. So plan accordingly. Also as a bonus this bracket should have a hole big enough for the center exit tube to go through and be held in place.

Final step is to set up the water pump and coolant.

You now have a liquid cooled computer.

Don't even bother trying this unless you have advanced computer knowledge and good problem solving skills. Any damge to your computer is not my responsibility. This is ONLY THEORY.

In the next couple of weeks I will be making a video and a Jpeg tutorial of me making this actual system and using it. Until then. This is ONly theory.

Give me thoughts or concerns/ hatred and contempt.

Ty for reading.

If you are pumping ice water through the lines it won't last long. You'll get condensation on the feed lines. Which will get to the electronics inside.

Not sure how you'd accomplish making the water blocks. Having some company machine them would cost more than buying them prebuilt. If you had machine tools I guess you could do it yourself.

I wouldn't trust caulking under pressure. I'd want something which could use compression fittings or be soldered.

I have a friend who constantly does experiments with water cooling for fun. About a year ago he tried making a normal open loop PC but he 3D printed a small tray with channels and a tunnel guider/silo, it was a two bit part. You would put the guider on top of the tray and it was designed in a way where you would fill up the guider/silo with ice and the ice would fall into the channels inside the tray and would stay there, the water inside the waterloop would get pumped thru the tray and the water would pass thru the ice essentially cooling it. Over the time as the ice melts that the water passes thru, the ice would drop down from the silo, so it was an automatic process, and the extra water from the melted ice would go down a tube and out of his window.

Now you may be thinking, wow, what a great idea, I will just fill up the silo with ice every few hours, pull up my overkill overclock and game until I ran out of ice and then go back to my normal overclock! But no, what effectively happened was, after about two hours of gaming, the water would get so much warmer that the ice would melt in minutes rather than one icecube which took about 10-15 minutes to melt and times that with a bowl of ice in the silo, but that was at idle, while gaming, that ice in the silo which is equivalent to a bowl, would be gone in less than half an hour rather than an hour and a half at idle. He also had to run two pumps, one pumping into tray and another out of tray into the system as there was no pressure since the tray was open. He decided to run this for a month anyway and what happened was; he was getting sick of dedicating his freezers into ice making machine and have to keep pausing every hour just so he can make a trip to his freezer and back.

What you can take from this is; ice will melt, and it will melt even quicker as the PC goes under load, ice is made out of water, you have to thinking how to get rid of that water and just like velocityg4 said, if this gives someone an idea to start shoving ice cubes down his reservoir, make sure theres nothing underneath it, because water will drop from outside the reservoir and you will make bottom of your PC a pond.
