How to Watercool a PC
Intro: How to Watercool a PC
Why would you want to water cool a PC? First of all it can much more quiet and it drops the temperature of your computer greatly. My quad core went from 50C under load to 28C Idle and under load! It is also good for overclocking. When you overclock the components of a PC get hot. The more you do it the hotter they get. It gets to a point were air cooling just won't cut it.
I really enjoy water cooling and it recently became one of my new hobbies. A water cooling rig requires maintenance. You need to know your way around a computer pretty well to be able to do this. I've been building computer since I was 10 and this really pushes you to the limit. I want to go even farther and try vapor phase change cooling. It's pretty much building a refrigerator inside of your computer. Drops things to around -20C

STEP 1: Finding Your Way Around.
First know your way around a computer. Refer to the pictures.
STEP 2: Picking Out the Parts.
Deciding on the parts depends on how much you want to spend. I spent about $275 on my current setup. Its going to be about $375 once I watercool my GPU. A good kit I would recommend is this oneone from petra's tech shop for $250. It has pretty much every single part my kit has. I didn't even know there was this kit before I bought from them. The people there are really nice. ThisThis kit is better for a cheaper build or a smaller system that doesn't throw off as much heat. These kits aren't like ones you will see on newegg or other computer stores. They have a good combination of parts from different company's. The best watercooling rig has parts for all different companies.
You will also need about 10-15 gallons of distilled water. You can pick this up at your local grocery store. You also need tubing. You need to buy the right size tubing according to the type of pump, radiator, waterblock, and reservoir have. They are called barbs. I prefer 1/2 barbs. Make sure all your barbs are the same size. I recommend you use Tygon tubing. You can also use deionized water. I finally figured out the differences, I was pretty confused. Deionized water is less pure then distilled and still has some minerals and things like that in it. Both are still a bit conductive.
You also need some thermal paste. It helps create a strong bond between the CPU and water block so the heat can transfer. You can get a tube of it for about $5

STEP 3: Preparing to Install.
Once you get all your parts I would read through all the manuals. I never read manuals, but for watercooling I would. They have warnings that could really mess up your rig if you didn't pay attention to that. After you do that you need to do what is called flushing. When the parts are manufactured they have oils and grime and other things from them being made. If you just run your rig like that you will have dirt and grime flowing through all your parts and it will start to clog. Get some of your tubing cut it short and hook it up to one end of your radiator. Get a funnel and run about a gallon of distilled water through it. It helps to shake it up and around the radiator. Also heating the water helps it too. Next take apart your water block which should be pretty simple just unscrew a few screws. Get some rubbing alcohol and rub it through all the groves in your block.
STEP 4: Installing
Take out all the parts of your computer you won't be using. Such as your ram HDD's and GPU if you aren't water cooling it. Your going to need to pretty much have to take apart your computer anyways to install the water block.
Take the motherboard out of your case and put it in a safe place to work on it where static won't get to it. Put a dot sized dab of the thermal paste I mentioned before only a dot or 2. Get your screws that came with the waterblock and stick them up through the bottom of where your heatsink would screw in. Put the heatsink on and secure it.
It is hard to explain since all blocks mount a bit different. Your block should come with some kind of diagram. Think through where you are going to be installing you radiator and water pump. You might have to drill some holes into your case if you are mounting your radiator outside of your case. Once you found the places mount and screw them into place. Put your computer back together with only the essentials as you won't be needing to be able to boot just turn it on.
Plan out how you are going to do the tubing and connect them all on the valves. Get some hoseclamps and tightly secure them on. You might need to use kind of lubricant to get them to slide on. Make sure have things how you want them because it is extremely hard to get the hoses back off.

STEP 5: Leak Testing.
This step is crucial because if you have everything in your rig and it does happen to have a major leak it could ruining your computer. This is why you took out everything you don't need. Stuff your case with paper towels and power it on. Watch it for about 10 minutes and go do something for 30 minutes or an hour. Check on it everyonce and a while. You should leave it on for 12-24 hours. 12 is fine but more if you are really concerned. You leave it on so long because small leaks may take time to emerge. The paper towels can also help you find where the leak is. If everything is good and your computer didn't short itself out your good!
Another thing of I just thought of for leak testing is that if your pump doesn't use your PSU for power and the wall you can just plug that in. Another thing you can do is get an extra PSU and just hook the pump up to that. Then you can jump start it. Find a green and black wire on the Motherboard power connector and get a paper clip and bridge the connections. Make sure your PSU isn't plugged in when you do this.

STEP 6: Putting Everthing Back In.
Put all the things you took out and put them back in. If you did everything right your computer should turn on and be fine. Monitor temperatures for a bit to see if everything is going right.

STEP 7: Additives
There are quite a few things you can add to your loop.
A few I recommend are:
PT nuke - It kills all kinds of bacteria and helps keep your loop from becoming dirty as fast.
Anti Freeze - There seems to be a big debate about this going on in the comment section. I use it and it does seem to help. I mix it in a 1:9 ratio to your water.
Liquid Coolants- There are a whole bunch of these, these are most of the time full water replacements. I have not had any experience with these, but I have mostly heard good things about them. Frozen Cpu stocks a whole bunch of different kinds.
Things to STAY away from:
UV dyes - Not all are bad, but some after a while will soon break down and become thick and murky and can damage pumps and reduce water flow. Make sure to look around and see if any of the reviewers of the product have been using it for a couple months before you buy it.

STEP 8: Some Extra Tips.
If your wiring is a mess you can drill some holes where you motherboard rests and feed the cables behind where you motherboard sits and stick them through the hole. It really makes things look a whole lot better.
Get all the bubbles out of your reservoir. It increasing water flow.
Check your water frequently, It might start to grow some things in it or get some dirt in it if you didn't get all the crap out of it when you flushed out the parts.
Put some anti freeze in your water. Put a little in it helps with the heat transfer.
Never use Aluminum and copper or any other different kind of material on the water blocks. It can cause bad reactions. There are some chemicals you can add to protect them but I still don't recommend it.
Keep some extra tubing and distilled water around. If you don't have you reservoir sealed right or just from time the water will evaporate.
If you use black tubing it keeps things from growing in your loop.
KEEP EVERYTHING. Keep all the extra screws you have an old parts. Stuff like that. I don't know how many times all my old stuff I kept has helped me out.

Did you ever wonder why Icebergs are the freshest water on earth, even though they are formed from seawater? Why doesn't the salt freeze in with it? Perhaps it is the effect of basic chemistry that makes a different liquid with different properties, but somehow EG is exempt from this and I didn't know because somehow EG is not water-soluble.
Also, if it is to prevent boil-off of the water, then why do they both fume equally when the mixture does hit it's boiling point?
Try holding a brick of solid sodium and go jump in a lake. Chemistry will have a lesson for you too.
FYI, the pressurized system is to prevent boil-off. The EG resists surface-boiling on contact with the water-jacket walls around the combustion chambers. You should review the temperatures in the water-jacket near the combustion chambers, or at least combustion-chamber temperatures in general.
BTW....Water = water, EG = EG, water + EG = coolant. Go ahead and test your theory by running your car on water alone then. Obviously, in a tropical environment, EG serves no purpose, right?.
EG reduces the corrosive effects of water. EG lubricates the water-pump and seals. EG improves the heat-transfer of water because the solution has a better ability to move heat than water alone. Accept and move on.

Where you get this anecdotal-science of "surface area" is beyond me. Furthermore, you are getting a little too hyper without actually getting into chemistry yourself. Water does not react with anything, however, other things react with water. FYI, pure sodium explodes on contact with water Mr. Bill Nye. Your reference to "acid/base burns" clearly shows you don't know where sodium fits in on the scale. Try looking at a basic pH scale for a little help.
"the higher the vapor pressure, the closer it is to the point of vaporization"
Me thinks you have your science backwards, and EG has no noteable effect on the vapor-pressure of water or a mixture therein. What you are referring to is "evaporative pressure" BTW, which is again unchanged. Maybe you should consult the Clausius-Clapeyron relation and do your math again. As such an esteemed physicist as you are, you should already be familiar with it.
Salt does not freeze with icebergs because the freezing point for sodium is so much lower than water. Any potentially-trapped sodium would literally melt it's way down through the ice to be reclaimed by seawater, if it could be trapped at all in the freezing process. Why do you think salt melts ice on contact? Ever heard of the "ice-and-table-salt deep-freezer"? Apparently not.....but I suppose pouring salt on ice cubes increases their surface area, as opposed to the accepted science that the salt is soluable in water and changing it's properties such as it's freezing point....
I will continue this fruitless debate no further, as there is no proving fact or fiction to you. Go tell a particle-physicist about your "surface-area" theory, I'm sure they'll need a good laugh. Maybe you could revolutionize hydraulic mechanics with this new theory too. Why waste time here, you have an entirely-new scientific frontier to explore, and prove wrong hundreds of years of scientific study!

You are completely accurate in stating that maturity has nothing to do with age. It is easy to find a particular 5 year old child that is more mature than some octogenarians. If that is what you were stating. Experience comes with age. Maturity is entirely unrelated. Explain, please, in what way my reply was immature, or in what way it attacked you character. I merely set up the three likely possibilities as to why you would be responding the way you began to, and ordered them from most to least likely. You on the other hand, in reply, essentially pulled an adult version of the child's "Bounces off me and sticks to you!" without any explanation of why, or any facts. I am not saying that you are immature, but you certainly are acting like it. True it could be that you are just having a bad day, but that's psychology, and still no excuse.
I mentioned both sodium and sodium chloride, because I realize that they dissociate into separate ions in solution, and you seemed to be implying that because an ionic compound was dissolved, that it was melted. This is incorrect. An ionic compound in solution, is, as I said, dissociated, not melted. As for the sodium which I DID mention (I have been using caps because you seem to be skimming my replies and skipping things...) you will find by looking it up that the melting point of PURE sodium is very close to the vaporization point of pure water. Not even remotely near or below the freezing point of water.
You also tried to imply that I was saying that the solution of sodium chloride and water has a freezing point lower than pure water not because this salt influences the properties of the solution, while I stated that it did, and a SIMPLIFIED VERSION of WHY it did. I did so by referring you to the colligative properties of solutions, which you apparently still haven't looked up. Also you state that I am mistaking the difference between an ionic solid dissociated in solution, and a melting/freezing point, which, from what I have been reading, is either exactly what YOU did in the
***"Salt does not freeze with icebergs because the freezing point for sodium is so much lower than water. Any potentially-trapped sodium would literally melt it's way down through the ice to be reclaimed by seawater, if it could be trapped at all in the freezing process."***
or else you have horrible grammar, which does not seem to be the case.
You resort to calling me a little boy, and then imply that you are far wiser than I am, me being obviously practically and infant... you that I have a weak grasp of science and social behavior, but provide no logic to back up your claims, you insult me again, by calling what is considered a man, in both this society, and long before in many other societies, a "little boy", and call my response to you a personal attack. Again you take exactly what I said,
***"Also you are constantly insulting me to try and prove your nonvalid point, this is a sign of immaturity, or foolishness, or both (even without the nonvalid point). You decide."*** (I took your earlier incredible sarcasm and implication of how completely moronic I was as an insult, if i should not have, please explain why. It seems insulting to me and would as well to most logical people.)
and attempt to turn it around and say that I am the guilty party, while at the same time making immature attacks on me and using a stereotype fallacy. It has been said that imitation is the sincerest form of flattery, but I don't think this is what was meant. How have I attacked you personally or otherwise? I merely requested that you stop attacking me and pondered why you would feel the need to do so.
