The Meshify 3 supports radiator up to 360 mm in the front, and 280 mm in the top (120 in rear), but there are some restrictions to keep in mind.
- Top radiator max width: 148 mm
- Front radiator max width: 155 mm
- Rear radiator max width: 128 mm
In the front of the case, the maximum radiator length is 420 mm with the air guide (ramp) in place.
With the air guide (ramp) removed, the max length is 445 mm:
The maximum GPU length in the case is 349 mm. If installing a radiator in the front, you need to reduce the GPU length with the thickness of the radiator.
If you, for example, would install a 30 mm thick radiator in the front, the maximum GPU length would be (349 - 30) 319 mm.
