El paquete normalmente incluye:
- Deepcool UL551 ARGB CPU Cooler (Heatsink with pre-attached fan)
- Intel Mounting Brackets and Screws
- AMD Mounting Brackets and Screws
- Placa posterior de Intel
- Pasta térmica
Installation for Intel LGA1700/1200/115X:
- Preparar la placa base: Place the Intel backplate on the backside of the motherboard, aligning the holes with the CPU socket.
- Instalar separadores: From the front side of the motherboard, screw in the appropriate Intel standoffs into the backplate.
- Aplicar pasta térmica: Clean the CPU surface. Apply a small amount of thermal paste (pea-sized dot) to the center of the CPU's integrated heat spreader (IHS).
- Mount Cooler: Carefully place the UL551 cooler onto the CPU, ensuring the mounting holes on the cooler align with the standoffs.
- Enfriador seguro: Use the provided Intel mounting screws to secure the cooler to the standoffs. Tighten screws in a diagonal pattern until snug. Do not overtighten.
- Conectar cables:
- Conecte el cable del ventilador PWM de 4 pines al encabezado CPU_FAN en su placa base.
- Connect the 3-pin ARGB cable (+5V-D-G) to an available Addressable RGB header on your motherboard.
Installation for AMD AM5/AM4:
- Preparar la placa base: Remove the plastic retention modules from the motherboard, but keep the original AMD backplate.
- Instalar separadores: Screw in the appropriate AMD standoffs into the original AMD backplate.
- Aplicar pasta térmica: Clean the CPU surface. Apply a small amount of thermal paste (pea-sized dot) to the center of the CPU's integrated heat spreader (IHS).
- Mount Cooler: Carefully place the UL551 cooler onto the CPU, ensuring the mounting holes on the cooler align with the standoffs.
- Enfriador seguro: Use the provided AMD mounting screws to secure the cooler to the standoffs. Tighten screws in a diagonal pattern until snug. Do not overtighten.
- Conectar cables:
- Conecte el cable del ventilador PWM de 4 pines al encabezado CPU_FAN en su placa base.
- Connect the 3-pin ARGB cable (+5V-D-G) to an available Addressable RGB header on your motherboard.

Instrucciones de funcionamiento
Once installed, the Deepcool UL551 ARGB CPU Cooler operates automatically based on your motherboard's fan control settings and the CPU temperature. The 4-pin PWM connector allows the motherboard to dynamically adjust fan speed for optimal cooling and noise levels.
Control de iluminación ARGB:
The Addressable RGB (ARGB) lighting can be controlled via your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync) or a dedicated ARGB controller (if purchased separately). Ensure the 3-pin ARGB connector is correctly plugged into a +5V-D-G header on your motherboard.
Mantenimiento
El mantenimiento regular ayuda a garantizar un rendimiento óptimo y la longevidad de su enfriador de CPU.
- Eliminación de polvo: Periodically (every 3-6 months, or more frequently in dusty environments) use compressed air to blow dust out of the heatsink fins and fan blades. Hold the fan blades gently to prevent them from spinning rapidly during cleaning, which can damage the bearing.
- Pasta térmica: The thermal paste typically lasts for several years. If you notice a significant increase in CPU temperatures, consider reapplying fresh thermal paste. This involves carefully removing the cooler, cleaning off old thermal paste from both the CPU and cooler base, and applying new thermal paste.
- Inspección del ventilador: Check the fan for any signs of wear, unusual noises, or obstructions. Ensure cables are not interfering with fan rotation.
Solución de problemas
If you encounter issues with your Deepcool UL551 ARGB CPU Cooler, refer to the following common problems and solutions:
- El ventilador no gira:
- Verifique si el cable del ventilador PWM de 4 pines está conectado de forma segura al encabezado CPU_FAN en la placa base.
- Ensure the CPU_FAN header is enabled in your motherboard's BIOS/UEFI settings.
- Verify that the fan is not obstructed by cables or other components.
- Sin iluminación ARGB:
- Ensure the 3-pin ARGB cable (+5V-D-G) is securely connected to an ARGB header on your motherboard.
- Confirm that you are using a +5V ARGB header, not a +12V RGB header (which can damage ARGB components).
- Check your motherboard's ARGB software to ensure lighting effects are enabled and configured correctly.
- If using an external ARGB controller, ensure it is powered and functioning correctly.
- Altas temperaturas de la CPU:
- Verify that the cooler is securely mounted to the CPU and making proper contact.
- Ensure sufficient thermal paste was applied and spread evenly (or that the pre-applied paste was not disturbed).
- Check for excessive dust buildup in the heatsink fins and fan.
- Confirm that the fan is spinning at an appropriate speed (check in BIOS/UEFI or monitoring software).
- Ruido inusual del ventilador:
- Compruebe si hay cables u obstrucciones que golpeen las aspas del ventilador.
- Ensure the fan mounting screws are tightened correctly.
- If the noise persists, the fan bearing might be failing. Contact support if under warranty.
Consejos para el usuario
- Always ensure proper thermal paste application for optimal heat transfer. A pea-sized dot in the center of the CPU is usually sufficient.
- Antes de comprarasing, double-check the cooler's dimensions (124 x 124 x 65 mm) to ensure it fits within your PC case and does not interfere with RAM modules or other components.
- Utilize your motherboard's fan control software to create a custom fan curve that balances cooling performance and noise levels according to your preference.
- For ARGB lighting, explore different effects and synchronization options available through your motherboard's software to personalize your build.
