How to Install a 360mm Liquid Cooler in the SKY Chassis: Assembly and Airflow Guide

The Challenge of Large Radiators in 2026

Modern hardware generates heat lots of it. If you’ve upgraded to a high-end processor, a 360mm liquid cooler (AIO) isn't a luxury; it’s a necessity. The Hiditec SKY chassis, with its dual-chamber design and panoramic glass, is optimised for this, but do you know how to make the most of the vertical airflow?

Compatibility and Dimensions: Where Does the Radiator Fit?

The SKY is a versatile chassis designed for enthusiasts. Unlike traditional cases where the radiator only fits at the top, here you have strategic options:

• Bottom (Recommended): Ideal for taking advantage of the fresh air coming directly from the floor.

• Side: Perfect for "push" configurations that exhaust hot air out of the case without passing over the motherboard.

• Top: The classic option to act as a hot air exhaust.

Step-by-Step: Bottom Mounting for Vertical Flow

Mounting the radiator at the bottom is the trend in "showcase" style chassis like the SKY. Here’s how to do it right:

• Fan Orientation: Set them to intake mode. We want the cold air from the outside to pass through the radiator fins immediately.

• Tube Management: Ensure the tubes are oriented towards the right side (cable management area) so they don’t interfere with the GPU’s aesthetics.

• Fixing: Use the long screws included in your cooling kit to pass through the fan and anchor it firmly to the chassis.

The Pump and Air Bubble Myth

Many users fear that placing the radiator at the bottom damages the pump. In the Hiditec SKY, this is well-accounted for. As long as the CPU block (where the pump resides in most AIOs) is physically lower than the tube inlet/outlet points on the radiator or the upper reservoir, air will not get trapped in the motor. This ensures silent operation and an extended lifespan.
