Case Fan

• Q1: What sizes are available for case fans? How to choose?

  A: Common sizes are 120mm and 140mm (mainstream). For larger cases, 200mm fans can be selected. Choose based on the size of the fan mounts in your case.

• Q2: How to distinguish the intake and exhaust directions of a fan?

  A: The side with the frame (support structure) is the exhaust direction, and the side without the frame is the intake direction.

• Q3: What is the difference between PWM fans and regular 3-pin fans?

  A: PWM (4-pin) supports intelligent speed control and is quieter. 3-pin fans require manual adjustment or have a fixed speed.

• Q4: What to do if the fan is too noisy?

  A: Check if it is not securely fastened, if the speed is too high, or if there is dust accumulation. You can replace it with a quieter fan or reduce the speed through software.

• Q5: How to synchronize the lighting effects of RGB fans?

  A: Connect to the motherboard RGB interface (such as 5V ARGB or 12V RGB) and control it with the manufacturer's software.

• Q6: How many fans does a case need?

  A: It is recommended to have at least 1 intake and 1 exhaust to form an airflow channel. High-end configurations can increase to 3 intake and 3 exhaust.

• Q7: What is the difference between wind pressure and airflow of a fan?

  A: Wind pressure type is suitable for radiators or dense areas. Airflow type is suitable for open spaces for quick air exchange.

• Q8: How to clean case fans?

  A: After powering off, use a soft brush or compressed air to clean the fan blades. For stubborn dust, use a cotton swab dipped in alcohol to wipe.

• Q9: What is the general lifespan of a fan?

  A: About 3-5 years, depending on the bearing type (hydrodynamic bearing > ball bearing > sleeve bearing).

PC Case

• Q1: How to choose the size of a case?

  A: Based on the motherboard specification (ATX, M-ATX, ITX), graphics card length, and radiator height.

• Q2: Does the material of the case affect cooling?

  A: Metal materials have better thermal conductivity, but cooling mainly depends on the airflow design, not the material itself.

• Q3: What is a vertical airflow case?

  A: Heat is drawn in from the bottom and exhausted from the top, using the principle of hot air rising to improve cooling efficiency.

• Q4: How to check the supported water cooling radiator specifications of a case?

  A: Check the cooling support parameters on the product page, such as top support for 360mm radiators.

• Q5: What to do if the case doesn't have enough hard drive bays?

  A: You can install a hard drive bracket or use an external hard drive enclosure. Some cases support back-mounted SSDs.

• Q6: Is a dust filter necessary? How often should it be cleaned?

  A: It is recommended to install one and clean the dust filter once a month to maintain cooling efficiency.

• Q7: How much cable management space is appropriate for a case?

  A: It is recommended to have ≥20mm space behind the back panel for easy cable management and to avoid of the side panel.

RGB Cables

• Q1: How to synchronize RGB cables with the motherboard?

  A: Connect to the motherboard's RGB interface (5V ARGB or 12V RGB) and install the control software.

• Q2: Can RGB cables be used on a motherboard without an RGB interface?

  A: You can purchase an independent RGB controller, powered by SATA or USB, to control the lighting.

• Q3: Do RGB cables consume a lot of power? Do they need additional power supply?

  A: Low power consumption, but when multiple devices are daisy-chained, it is recommended to power them through SATA or a large 4PIN interface.

• Q4: What to pay attention to when installing RGB cables?

  A: Avoid excessive bending and ensure the interface is correctly oriented.

• Q5: What to do if the colors of RGB cables are not synchronized?

  A: Check if the interface protocols match (e.g., 5V ARGB does not support 12V RGB), and update the software and firmware.

• Q6: Can RGB cables from different brands be mixed?

  A: They can be mixed if the interface protocols are consistent, but the lighting effects may be limited by the control software.

• Q7: Is it dangerous if RGB cables heat up?

  A: LED light beads have low heat generation, and there is no risk under normal use. Avoid covering flammable materials.

PSU Extension Cables

• Q1: What are the uses of PSU extension cables?

  A: For cable management, extending the length of the original cables, and adapting to special case layouts.

• Q2: Do extension cables affect power supply stability?

  A: High-quality cables have no impact, but low-quality cables may cause voltage instability or short circuits.

• Q3: How to choose the length of extension cables?

  A: Based on the case size, common lengths are 30cm (for ATX cases) and 50cm (for full-tower cases), with a 10cm redundancy.

• Q4: Are extension cables necessary for modular power supplies?

  A: Not mandatory, but the original cables may be too rigid for cable management, and extension cables are more flexible and aesthetically pleasing.

• Q5: How to choose the material of extension cables?

  A: Prioritize 16AWG cable diameter and silicone mesh sheathing for high temperature resistance and good flexibility.

• Q6: Can PSU extension cable interfaces be mixed?

  A: No! They must strictly match the power supply interface type (e.g., PCIe 8pin, CPU 4+4pin).

• Q7: Do extension cables reduce power supply efficiency?

  A: Theoretically, they increase resistance, but the loss from high-quality cables is negligible.

• Q8: What is the difference between modular cables and extension cables?

  A: Modular cables directly replace the original cables, while extension cables are connected to the end of the original cables, offering higher flexibility.

• Q9: What to do if the system does not power on after installing extension cables?

  A: Check if the interfaces are securely plugged in and correctly oriented, and rule out short circuits or poor contact.

RGB Accessories

• Q1: What are common RGB accessories?

  A: LED strips, fan hubs, RGB brackets, graphics card support rods, memory heat spreaders, etc.

• Q2: How to synchronize RGB accessories with the motherboard?

  A: Through the motherboard's RGB interface or controller, and some require dedicated software (such as iCUE, Aura Sync).

• Q3: Is an RGB controller necessary?

  A: It is needed if the motherboard does not have an RGB interface, or if you need to independently control multiple lighting groups.

• Q4: How to power RGB LED strips?

  A: They can be powered through the motherboard's RGB interface, SATA, or USB interface (depending on the product design).

• Q5: What to do if the colors of RGB devices are inconsistent?

  A: Calibrate the color values in the software, or check if they are the same protocol (e.g., 5V ARGB).

• Q6: Where is a good place to install RGB LED strips in a case for the best effect?

  A: Top/bottom edges, behind the motherboard tray, below the graphics card, and other concealed areas.

• Q7: Can multiple RGB devices be daisy-chained?

  A: Devices that support daisy-chaining can be connected through the same interface, but pay attention to the voltage limit.

• Q8: What to do if RGB accessories cause system lag?

  A: It may be due to software conflicts. Update the drivers or close unnecessary RGB control processes.

CPU Liquid Cooler

• Q1: Which is better, water cooling or air cooling?

  A: Water cooling has higher cooling efficiency (especially for high-end CPUs), but air cooling is quieter and maintenance-free.

• Q2: How to install an all-in-one (AIO) water cooler?

  A: Place the cold head on the CPU, secure the radiator at the top/front of the case, and connect the fans and pump power supply.

• Q3: What is the lifespan of a water cooler?

  A: AIO water coolers last about 3-5 years; custom water cooling requires regular maintenance (liquid replacement, cleaning).

• Q4: Does water cooling require liquid maintenance?

  A: AIO water coolers do not require maintenance; custom water cooling should replace the coolant every 1-2 years.

• Q5: Can water cooler leaks damage hardware?

  A: High-quality brands offer leak warranties, but you need to keep purchase receipts and evidence of damage.

• Q6: What to do if the water cooler pump is too noisy?

  A: Check if it is not installed properly or if there are air bubbles. You can adjust the speed or contact customer service.

• Q7: Does the thickness of the radiator significantly affect cooling?

  A: Thicker radiators have stronger cooling capabilities, but ensure case compatibility (commonly 25-45mm).

• Q8: Which CPU sockets are supported by water coolers?

  A: Mainstream brands are compatible with Intel LGA1700/1200 and AMD AM5/AM4, and you need to confirm the mounting brackets.
