It lets you bridge the gap when the fan's stock cable isn't long enough to reach the header, while still supporting full PWM speed control so your fan's speed is regulated automatically by the motherboard.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this cable compatible with 3-pin fans?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! While the connector is a 4-pin PWM type, it is backward compatible with standard 3-pin fans. When used with a 3-pin fan, the fan will run at a fixed speed rather than variable PWM speed — but it will connect and operate correctly.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How many cables are included in this pack?\u003c\/h4\u003e\n\u003cp\u003eA: This listing includes a pack of 5 PWM 4-pin fan extension cables, giving you enough to connect multiple fans or to keep extras on hand for future builds or upgrades.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Will this cable affect my fan's speed control or performance?\u003c\/h4\u003e\n\u003cp\u003eA: No. The cable is a passive extension — it simply passes the PWM signal from the motherboard header through to the fan. Your motherboard's fan control software and BIOS settings will continue to regulate fan speed as normal, with no loss of performance.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does a PWM 4-pin CPU fan extension cable do?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A PWM 4-pin CPU fan extension cable extends the connection between your motherboard's fan header and your CPU or case fan.
