5. Configuración
5.1. Installing the M.2 NVMe SSD
- Carefully align your M.2 NVMe SSD with the M.2 slot on the JEYI SK4 adapter. The adapter supports various M.2 SSD lengths (2230, 2242, 2260, 2280).
- Insert the SSD into the slot at an angle and gently push it down until it is parallel with the adapter board.
- Secure the SSD with the provided screw or movable copper stud at the appropriate length. The adapter includes movable copper studs to accommodate different M.2 SSD lengths.

5.2. Installing the Warship iStorm Cooler
- Apply the thermal pads to the M.2 NVMe SSD. Ensure good contact between the SSD chips and the thermal pads.
- Place the Warship iStorm cooler assembly over the SSD and adapter, aligning the mounting holes.
- Secure the cooler to the adapter using the provided screws. Do not overtighten.
5.3. Installing the Adapter into a PCIe Slot
- Power off your computer and disconnect the power cable.
- Abre a carcasa do teu ordenador.
- Locate an available PCI Express X4, X8, or X16 slot on your motherboard.
- Remove the corresponding expansion slot cover from your computer case.
- Carefully insert the JEYI SK4 adapter into the chosen PCIe slot, ensuring it is fully seated.
- Secure the adapter to the computer case with a screw.

5.4. Conexión do cable de alimentación
- Locate the small power cable extending from the Warship iStorm cooler.
- Connect the SATA 15-Pin 5V connector of this cable to an available SATA power connector from your power supply unit (PSU). This connection is essential for the cooling fan to operate.

Figura 5.3: Cooler power connection. This image highlights the 50cm long SATA 15-Pin 5V power cable that connects the cooler fan to the power supply unit.
6. En funcionamento
After successful installation, close your computer case, reconnect the power cable, and power on your computer.
- Instalación de controladores: Most modern operating systems (Windows 10/11, Linux kernels 4.0+, macOS) have native support for NVMe SSDs and typically do not require additional drivers. If the SSD is not detected, check your motherboard's BIOS/UEFI settings to ensure PCIe slots are configured correctly and NVMe support is enabled.
- SSD Initialization: For a new SSD, you may need to initialize it and create partitions using your operating system's disk management tools before it can be used.
- Rendemento de refrixeración: The integrated Warship iStorm cooler with its fan will automatically operate to dissipate heat from the NVMe SSD, helping to maintain optimal performance and prevent thermal throttling.

Figura 6.1: Cooling performance indication. This image suggests that the iStorm Pro cooler can reduce SSD temperatures by 10-40°C, contributing to stable operation.
7. Mantemento
- Limpeza: Periodically inspect the cooler fan and heatsink for dust accumulation. Use compressed air or a soft brush to gently remove dust. Ensure the computer is powered off and unplugged before cleaning.
- Comprobación de conexión: Occasionally verify that the adapter is securely seated in the PCIe slot and that the SATA power cable for the cooler is firmly connected.
- Thermal Pads: If you need to remove and re-install the SSD or cooler, inspect the thermal pads. Replace them if they appear damaged or have lost their adhesive properties to ensure effective heat transfer.
