Here is a quick list of the tools you will need to install a loop.
- Screwdriver
- Allen wrench (aka hex wrench)
- Measuring tape
- Flashlight
- Towels or rags (for potential spills)
- Pliers
- Funnel (for feeding coolant)
Most of the tools are common enough that you probably already have them or can buy them for cheap at a local hardware store.
1. Plan the Loop
The first thing to do is plan how you want to loop set up in your tower. You need to know exactly where your water blocks are going to go, the loop order, and how the tubes will connect them with the coolant. You do not want to just eyeball the form as you go, so take some time to draw out a rough schematic of the system you want.
Loop order can be flexible but at the very least, make sure the reservoir and the pump are right next to each other. Water blocks normally connect directly to the part they are meant to cool. Loop order does not generally affect performance unless you are trying to squeeze every ounce of efficiency out of it.
Also, make sure all other non-cooling components are situated correctly, such as casings, wiring, cables, etc. Thoroughly clean all loop components like the tubes, reservoir, pump, water blocks, etc.
2. Install the Water Blocks
The next step is to install the water blocks on the components. Most water blocks work the same, but there might be small variations depending on the type you get. Line up the holes on the water block with the holes on the component, and put the screws in. You may have to remove/move some internal components to situate the water blocks.
Before attaching the water blocks, you also might want to apply some thermal paste on the components where they connect. Make sure that you do not put the screws in too tight, or that the water block does not put too much pressure on raised structures like transistors, or you can damage your hardware.
3. Install the Radiator and Reservoir
The next step is to put in the radiator and reservoir. Typically, the radiator should be put near the vent that your fans usually occupy. You can also attach them to the bottom of your case or set them up externally outside the case. Like the water block, don't put the screws in too tight.
The best place for the reservoir is in the case where extra HDDs are supposed to go. You can mount the reservoir however you want. If the holes in your case are not spaced correctly to attach the reservoir, you can make extra holds very carefully by using a drill.
