英国采购需求：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 one of your air coolers, and I'm quite impressed with the majority of its features. However, there seems to be an issue with the temperature display; it's not functioning as expected. I've checked all connections and settings on my end, but unfortunately, the screen remains inactive. Could you please provide any guidance or potential fixes for this issue? If there are troubleshooting steps or common solutions available, I'd appreciate your assistance. Additionally, if this is a known concern, are there any repair options or parts that can be sent to resolve this problem? Looking forward to your prompt response.
