How to Watercool a computer - Part 1 of 2

2013-02-06
hey guys you're watching Jays $0.02 and today we're going to go ahead and do the popular request and I'm constantly asked is how do you put together a water cooling loop so since I have to drain mine pull all the water out of it I decided to go hitting all the parts out of the machine I'm going to show you guys exactly what you need to know when it comes to building the water cooling loop when building a custom loop there are specific parts that are required to complete the system of course you're going to have to have a block for your CPU this is what's going to transfer the heat into the water you're going to have to have a pump this right here is a MCP nine six six five five leave number the actual number of it yeah MCP six five five from Swift tech it's a variable speed it's a very high pressure pump you don't need to go this extreme but you obviously do have to have a pump you have to have a radiator you have to have a way to dissipate that heat you have to have a reservoir to hope have a place to fill the coin have a place to hold the coolant and of course you have to have the tubing which I already have connected here because I'm not going to redo it all and of course you have to have a fan you have fans for your radiator one of the most common things that I'm asked is how big should your radiator be well that really depends on how many pieces that you're going to be cooling inside your water cooling kit you could cool as much as just the CPU or you could cool the CPU the MOSFETs the motherboard the Northbridge if you're running AMD if you run a graphics card multiple graphics cards Ram there are so many ways that you can build this custom loop the size of your radiator and how many radiators really depends on what it is you're planning on cooling so if you're going with the bare minimum like a CPU we can get away with even just a single 120 millimeter radiator which is half of this this is a 240 radiator which is to 120 millimeter fans from my loop however I'm also including the water cooling for my GTX 680 here so that includes the price you have to include a graphics card water block my case I'm using a full cover water block which means that I'm adding a lot more heat to my system because graphics cards tend to get much hotter than CPUs so I included another triple Swift tech radiator right here let's go ahead and take these parts let's put them together in the PC and show you guys exactly what you need to do to take it from part to loop when it comes to applying the thermal paste you want to apply it directly to the CPU heat spreader there's a lot of different opinions and ideas going around about the proper way to install thermal paste I'm going to show you the way that I do it I tend to just take and put a few dots evenly spread out on the top of the heat spreader and then just take a business card or a credit card and you can use it to this evenly smear and apply the thermal paste and I know somebody watching this video is going to be like that's not the proper way to cut down the pace well you can eat me this is the way I've been doing it for years I've never once had a problem the thermal paste all it does is fill any gaps between the two metals as they touch and it promotes heat exchange between the block and the CPU and what you want to do when you're installing the block and this is true for any sort of heat sink or water block is you want to get two opposing corners started and you just want to get these just slightly tight and you want to work on a start pattern just like a heat sink you don't want to tighten down in a circular motion because then what you'll do is you'll create a bulge in the center and you'll have a gap you know what make very good contact which can lead to overheating okay so once we got the CPU block installed go ahead recommend installing your radiator the radiator is kind of the most bulky part to work with here so keep it firm in one hand and we're going to keep this very very clean people get your mind out of the gutter and then I would just keep in your other hand one screw ready so that you can get it hand tight to hold the radiator in place just a point I want to make when it comes to routing your tubing here my two thing was pretty much already all cut and ready to go because I removed it from a working system but what you want to be mindful of is how tight of a bin you put on the tube the tubing is very flexible especially if you go with a tube designed for water cooling from a reputable source like frozen CPU or performance pcs it's very very flexible however if you get to a certain point you're going to get a kink in it so you have two options you can get an anti keep a spiral piece of plastic that goes over without a tube I think it looks really tacky I don't like using anti kink coils the other thing you can also do is just plan really really well so for instance I changed it up the way my loop was routed here just slightly and so when going from the CPU block to the GPU it was putting as you can see right here how it flattens out a little bit this is flattening out which is reducing the water flow so all I need to do to fix that is just put the tube next to the bar about where I think it needs to be and then just slowly cut off about quarter inch increments of the tube and test fit until it's no longer kinking and then just leave it at that so you want to plan ahead when it comes to tubing you want to do some some test fit it doesn't really matter what order that you run the components in the most important part is that you have your pump being fed directly by your reservoir you want your pump pulling in from the reservoir and you want your pump to be lower than the level of your reservoir because you want gravity to feed into the pump we'll talk more about that when it comes time to fill in prime the system but it doesn't really matter as long as the reservoir goes before the pump the pump can go out to the graphics card then to a radiator then to the block then to the other radiator or in your case just block and radiator and it's fine now I'm getting your hand drop your wrist more break my arm go away he did break your arm off it's sort of in the way in order to mount your reservoir you might have to drill some custom holes my case for the reservoir it has an L bracket and I had to drill a hole into the bottom here to melt this down and the loop is now back together just that easy so I've got to go ahead and put some of these clamps back in place but I mean guys that's it so here's the order of my loop this is the way that I run my loop here I'll go from reservoir to pump to upper radiator to the CPU directly to the GPU then to the lower radiator back to the reservoir so that's my loop you
