How to find the right Graphics Card Fans AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Graphics Card Fans
- Blade diameter
- Measure the old fan's blade tip-to-tip diameter (common sizes are roughly 75 to 100 mm) and match it within about a millimetre. GPU shrouds leave little clearance, and a larger blade rubs while a smaller one moves less air.
- Connector and pinout
- Match the plug exactly: mini 4-pin or 2-pin single-fan plugs, or a combined plug that drives two or three fans from one header. GPU fan headers are not standard motherboard 4-pin headers, and many dual and triple fan cards run every fan from one combined lead.
- Mounting pattern
- Match the screw count and hole spacing on the fan frame or hub to the shroud, or buy a whole shroud assembly made for your card. Bare replacement fans with the wrong frame will not mount even when the diameter is right.
- OEM part number
- Read the label on the fan hub and search by that part number together with your exact card model. Board partners change fans between revisions of the same card name.
- Voltage and current
- Use 12 V fans, with a current rating at or below the original's. A fan that draws much more current than the original can overload the card's fan controller.
Brands that matter
- Power Logic: OEM fan maker found on many board-partner GPUs; often used as the reference part number.
- Everflow: OEM supplier of GPU cooler fans; good for matching originals by part number.
- FirstD: OEM fan maker used on many older and mid-range cards.
What to avoid
- Listings that give only a fan diameter without a connector photo or pinout
- Assuming a single-fan plug fits a card whose fans share one combined header
- Zip-tying case fans to a heatsink without checking card sag and slot clearance
Questions
Can I plug a GPU fan into the motherboard instead?
Yes, with an adapter, but the card will no longer control that fan, so you need to set a fan curve in the motherboard settings.
