Hello Reborm,

Thank you for raising this issue through the Intel Communities.

I appreciate you providing a photo of the processor, but I’m unable to clearly verify the details from the image. Could you please send a clearer picture?

Additionally, I have a few questions to help with the investigation:

• Did you experience any overheating before this issue occurred?

• While the processor was installed, did you notice any problems or unusual behavior?

Once I have this information, I’ll be able to guide you on the next steps.

One of the front IO usb slots on my case wasn’t working I’ve had it under a 280 arctic liquid freezer 2.

Hello Reborm,

Thank you for providing the new picture. Based on the image you shared, we are unable to determine if the processor is damaged. It would be helpful if you could provide additional pictures of the processor from different angles so that we can validate it more thoroughly.

Regarding the USB issue, having a 280 Arctic Liquid Freezer II should not affect USB functionality, so it’s possible that the issue may be related to the motherboard.

Additionally, I need to gather more information to better understand this concern:

• Have you experienced any overheating in your system? If yes, could you provide the temperatures at idle and under load?
• Are the other USB ports working properly, or does the issue occur only on a single port?
• When you check Device Manager, do you see any yellow warning signs?

Once I have this information, I can guide you through the next steps for further investigation.

Hello Reborm,

Thank you for providing the image of the processor. Upon validation, it appears that there is no visible damage.

For additional information, since you mentioned that you performed swap testing, could you please let me know the model of the other processor used?
