Water cooling for noobs

Water Cooling Guide

By Juggalo23451

Video explanation link as well as where to get wc parts below the tutorial


Well I have been water cooling for a lil over 2 yrs now so I would figure I would help and make a guide. So let's get started

[b]What is water cooling[/b]. More or less it is the same way how your car's radiator works to cool your engine except on a smaller scale .

[b]How much is it going to cost me[/b]- Depends on what you want to cool. The average coast for a cpu only loop is generally around 200-$$$. It will cost more if you want to add graphics cards, mosfets and etc. there is no real reason to water cool your ram,hdd. I don't see the point of water cooling your north bridge/south bridge either all it does is add restriction to your loop.If you want better temps on your chipset remove the old thermal paste with 90% Isopropyl alcohol or higher. Use a q-tip for this or a micro fiber cloth. Then put on new thermal paste like the ones listed below. but if you are going for insane overclocks go for it:)

What parts are needed? I will tell you the parts and suggest some parts as well.

[b]Tubing[/b] and lingo you may see(get 10ft for cpu only,15ft or more if adding more rads blocks and etc:)


The most common sizes for tubing for water cooling are

3/8 inch

7/16 inch-people use this size tubing on 1/2 barbs for a tighter fit/seal

1/2 inch


ID= Inner diameter

OD= Outer diameter

Primochill,tygon, masterkleer (budget)

Use tub cutters, razor or scissors to cut the tubing.


Dyes[/b] Do not use any dyes or additives. If you want color get colored tubing

[b]Reservoir [/b]( always higher then the pump)- holds water


For reses it is all about preference really, You have the Swiftech Micro revision res for like 20 bucks or you could spend up to 200 bucks on a res to.

[b]Pump[/b](always below the res)


check instructions to make sure you know where the inlet is and outlet- This is the whole heart of you water cooling loop. Pushes the water in you loop around. Getting the right pump is critical don't get the right pump may get poor flow in your loop/poor temps to. They are usually measured by gph(gallons per hour) The more gph the better.

MCP355,MCP655, OCZ hydro flow(budget),jingway,

Note: The mcp355(has 3/8 barbs) is slightly better than the mcp655(1/2 barbs)


Pump top[/B]-


Dont want to use 3/8 barbs on a mcp355 get a top:) and choose what ever barb or compression fitting you like. Getting a op will help maximize the efficiency of the pump.


[b]Water Blocks[/b](center is always the inlet)


There are great water blocks out there for the CPU and Gpus. If you are going for the absolute best one out there. Then the EK HF is the king right now. Ek is also the best for gpus as well.

XSPC Rasa water block(budget) this block is behind the ek hf by 3 degrees. XSPC for gpus as well.

[b]Thermal Paste[/b]-


MX3, MX4, OCZ Freeze, Shin Etsu, Indigo Extreme(the best but really expensive)



you will see g1/4 and g3/8. That is simply the thread size. What size barbs you get will depict on what size tubing you would want.

bitspower, enzotech,koolance

Compression fittings- Makes you loop look cleaner.


Has two parts the barb and a collar. The collar goes on the tubing first. Then mount the tubing on the barb. Screw down collar all the way.(video below) make sure to get the same id and od fittings as your tubing

[b]Radiators[/b](removes heat from you loop)-


inlet/outlet does not mater

Depending on what you want to cool will depend on the size of rad you want

Example a 240 radiators can cool most cpus., 360 rad for cpu and a gpu

Best rad right now is the GTX series radiators by Hw labs(loud setup)

Best rad(low noise) RX series rads by XSPC or SR-1 rad by HW labs

Budget rad Xspc rs.

P.s You can use a 77 Bonneville rad I believe if you wanted to.

[b]Fans(removes heat from the rad) and static pressure[/b]


What is static pressure. It is the measurement of air to be push through a restrictive object. So the better the static pressure the better the fan for your radiator.

Panaflo,delata, Kazes 120x120x38 are great for rads like the GTX

Gentle typhoons (AP-15) are great for rad like the Sr-1 and RX series rads. Why you ask the noise to cfm is great and it has good static pressure as well.

Yate Loons are a great budget fan

[b]Fan Controller[/b]

(controls the rpms of a fan)


Want to quiet down your set up getting a fan controller can help with that:)

[b]Clamps[/b] (secure them in the center of the barb)-


use clamps, zips, or worm clamps to secure your tubing

[b]Coolant[/b]- Distilled water is all you need.

Pt nuke as well to prevent growth in your loop


/ or just get a

silver coil.


[b]I have all the parts now what?[/b]

1. Loop order, I usually do res-pump-rad-cpu-res for example, but you do not have to do that order just make sure you have the res before the pump

2. Bust out a scratch piece of paper and pen. Draw a rectangle representing you case then. Draw another rectangle representing your mb. Location is key for a water cooling loop.

Draw some sketches on how you want your loop to go.

3. Mount everything up.

4. Start from one point in your wc loop.with the tubing attached to a barb,

take the excess and move it to the next point to your loop then cut.(Attach tubing)Repeat the process until you are done.

5. Take out loop of you case(up to you)

6. Hook the pump to your power supply(make sure nothing else is

hooked up to the psu)

7. Take a paper clip and put it in the green wire and connect any black wire. this will create a load to turn on your psu. Make sure the psu unplugged before doing this.

8. Fill up the res with distilled water all the way to the top with a funnel

9. Turn on the psu let the water go to about have way then refill the res.

10. repeat the process again until you do not need to fill the res up any more

[b]Bubbles[/b]- To get rid of bubbles tilt your case side to side, back and forward

Leak testing- I say a good 8-12hrs should be enough. You can do more if you would like.

Hook up everything/install wc loop if outside of case and enjoy your temps

[B]Dont feel like going custom get a XSPC Rasa Kit [/B]


If any additional help is need please feel free to pm me or ask a question here:)


strange, each time i try to view a video, i'm brought back to the main page :/

Yeah it's a bug. click the video twice, so you open it on youtube.com

very nice guide! Ill bookmark it for future wc projects.

the formatting is very very weird on this page 0_o

I just opted out of not going wced because I was unsure how to go about it. Bookmarked. Thanks

Thanks I was wondering about it to. It seems to be fixed since then:)

Great guide, you can use car heater cores as radiators, sometimes without modification even.

yeh i think it is a 67 Bonneville heater core

Can I get permissions so I edit and update with some new info?
