美国采购需求：CPU散热器、风冷散热器、风扇散热器、液冷CPU散热器、水冷散热器、ARGB散热器

I recently purchased an AIO CPU cooler from Amazon, but I'm encountering an issue where only the fan lights are operational. I've verified that all connections are secure and properly attached, but the cooler itself isn't functioning as expected. Given that it came with a 3-year warranty, clearly stated on the packaging, I would like to request a replacement. Please let me know the next steps to proceed with this warranty claim. Thank you!
