加拿大采购需求：电脑风扇、计算机风扇、CPU散热器、机箱风扇、机箱散热风扇、水冷散热器

I recently purchased three Cosmiq fans in January, but I've encountered an issue with one of them. Unfortunately, it seems that one of the fans isn't functioning properly. I'm hoping to get some assistance with this problem, as I really appreciated the quality and performance of the other two units. Could you provide guidance on how to proceed with resolving this issue? Whether it involves a replacement, repair, or any specific troubleshooting steps I should follow, I'd appreciate your help. Looking forward to your prompt response so I can get this sorted out as soon as possible!
