2. Información de seguridade
- Desconecte sempre a alimentación do ordenador antes de instalar ou retirar calquera compoñente.
- Handle the CPU cooler and motherboard with care to avoid damage to sensitive components.
- Use unha pulseira antiestática para evitar danos por descarga electrostática (ESD).
- Manteña as pezas pequenas lonxe dos nenos.
- Ensure proper ventilation inside your computer case for optimal cooling performance.
3. Contido do paquete
Verifica que todos os compoñentes estean presentes no paquete:
- SilverStone Nitrogon NT09-115X CPU Cooler (with pre-applied thermal paste)
- LGA 115x series backplate
- Mounting hardware (push-pins, screws)

4. Configuración e instalación
4.1 Preinstalación
- Ensure your motherboard supports Intel LGA 1156/1155/1150/1151 sockets.
- Limpa ben a superficie da CPU con alcohol isopropílico para eliminar calquera pasta térmica antiga ou residuos.
- If the cooler does not have pre-applied thermal paste, apply a thin, even layer of high-quality thermal paste to the center of the CPU's integrated heat spreader (IHS).
4.2 Instalación do refrixerador
- Place the LGA 115x backplate on the backside of the motherboard, aligning the holes with the CPU socket mounting holes.
- Carefully position the CPU cooler over the CPU, aligning the four mounting pins with the holes on the motherboard.
- Press down on each of the four push-pins until they click into place. Apply even pressure diagonally to ensure secure contact. The reinforced backplate design helps reduce motherboard bending and provides tighter CPU contact.
- Conecta o cable do ventilador PWM de 4 pinos do refrigerador á toma CPU_FAN da túa placa base.

5. Instrucións de funcionamento
The SilverStone NT09-115X CPU cooler operates automatically via its 4-pin PWM connection to the motherboard. The motherboard's BIOS or operating system software will control the fan speed based on CPU temperature, ensuring optimal cooling performance and noise levels.
- Control PWM: The fan speed will dynamically adjust between its minimum and maximum RPM (up to 2500 RPM) to maintain desired CPU temperatures.
- Fluxo de aire: The fan provides an airflow of up to 47 CFM.
- Nivel de ruído: The maximum noise level is 32.0 decibels, designed for quiet operation.

6. Mantemento
Un mantemento regular garante un rendemento óptimo e unha maior duración do refrigerador da CPU.
- Eliminación de po: Periodically (e.g., every 3-6 months), use compressed air to clean dust from the heatsink fins and fan blades. Ensure the fan is held stationary during cleaning to prevent damage to the bearings.
- Inspección do ventilador: Check the fan for any obstructions or unusual noises. If the fan is damaged or excessively noisy, consider replacing it.
- Pasta térmica: If you notice consistently high CPU temperatures, the thermal paste may need to be reapplied. This requires removing the cooler, cleaning both surfaces, and applying new thermal paste.
7 Solución de problemas
- Temperaturas altas da CPU:
- Asegúrate de que o refrigerador estea montado de forma segura e que faga bo contacto coa CPU.
- Verify that the thermal paste application is correct and sufficient.
- Check if the fan is spinning correctly and not obstructed by cables.
- Asegúrate de que haxa un fluxo de aire axeitado dentro da carcasa do teu ordenador.
- O ventilador non xira:
- Check if the 4-pin fan connector is securely plugged into the CPU_FAN header on the motherboard.
- Verify fan settings in the motherboard BIOS/UEFI.
- Ruído excesivo do ventilador:
- Limpa calquera po das aspas do ventilador e do disipador de calor.
- Asegúrate de que ningún cable toque as aspas do ventilador.
- Check for loose mounting screws or components.
