Which radiator should I use in my custom loop?

This is dependent on your chassis and what space it has available for your radiator. We would recommend making sure which size radiator your chassis can take before making your decision.

We usually recommend using a 360mm radiator if your chassis can fit it in. The thicker the radiator with more rows, the better. Some builders might want to use 2x radiators instead of one, which would be even better, but this depends on chassis space as well as budget.

What difference does radiator thickness make?

The thicker the radiator, the more heat dispersion you will have with your radiator however this will be most effective when pairing thicker radiators with higher pressure fans.

Please note: It is always better to have a larger radiator with less rows than a smaller radiator with more rows that is thicker.

What is the difference between a DDC and a D5 pump?
The D5 can offer larger flow rates at a lower pressure, while the DDC has higher pressure but lower flow rates. Important to note: The smaller DDC pumps can be a bit noisier than the D5 models.
If you are building an advanced loop with many angles and multiple water blocks, we’d recommend a pump with higher pressure. But if you are building a small form factor build with limited space we’d recommend the DDC
How will I know which waterblock will fit my CPU?

Firstly make sure you know which socket your CPU is.

Then if you head over on our site to your applicable CPU manufacturer category (AMD or Intel) and click on the CPU water block you’d like to view, scroll down to the description of the product, where a heading “Compatibility” will be listed. If you can see your CPU socket listed there then it will be compatible with your CPU.

Which fittings should I use if I am using hard tubing?

For hard tubing, if you are connecting fittings to tubing then you are going to want to use our 14mm rigid fittings which you can easily find on the dropdown menu at the top of our site under the following directory: Custom loop > Fittings > Rigid Fittings

Is there an alternative to bending tubing with a heat gun?

If you would rather not have to go through the trouble of bending your own hard tubes, then the best solution is to either consider using soft tubing in your build which will be much easier however not provide sharp edges aesthetic to your loop.

Alternatively, you could use angled fittings at each corner of your hard tubing’s angled cuts and connect all edges that way.
