PC Cooling Fans & Heatsinks

Q: What is the difference between PWM and DC PC cooling fans?

PWM (Pulse Width Modulation) fans use a 4-pin connector and allow the motherboard or fan controller to dynamically adjust fan speed based on temperature, resulting in quieter operation and better energy efficiency. DC fans use a 3-pin connector and regulate speed by varying voltage. For modern builds, PWM fans are generally recommended for superior thermal and noise management.

Q: How do I choose the right replacement GPU cooling fan?

To find the correct replacement GPU fan, you need to match the fan's dimensions (e.g., 102mm or 115mm), the connector type, and the specific GPU model (such as the RTX 3060, RTX 3070, or RTX 4090 Founders Edition). Check the part number printed on your existing fan or the GPU's documentation for the most accurate match.

Q: How many case fans do I need for a well-cooled PC build?

Most mid-tower PC builds benefit from at least two to four 120mm case fans — ideally with a front intake and rear/top exhaust configuration. Larger cases or high-performance systems with powerful CPUs and GPUs may require more fans. Using a PWM fan hub makes it easy to add and manage multiple fans from a single motherboard header.

Q: Can I use a USB cooling fan for my router or modem?

Yes! A USB cooling fan is a simple and effective way to reduce heat build-up in routers, modems, set-top boxes, and mini PCs. Simply plug it into any available USB port for instant cooling without requiring any additional power connectors or installation tools.

Q: What are ARGB fans and are they compatible with my motherboard?

ARGB (Addressable RGB) fans feature individually addressable LEDs, allowing for advanced lighting effects and full customization via compatible motherboard software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion). They connect via a 3-pin 5V ARGB header. Always verify that your motherboard has a 5V 3-pin ARGB header before purchasing ARGB fans.
