I've had to do this 2-3 times, it's a bit annoying.
IIRC, you go to the the warranty center (Intel® Warranty Center) and submit a request. Intel doesn't seem to have a dedicated RMA portal like a lot of companies do. I had to wind up submitting a support request, which turns into a phone call and email process. It costs nothing unless you want advanced RMA or rush shipping.
Thank you for joining the Intel communities.
If you need to get warranty for the unit you can do it here:
If you are an end user the warranty needs to be approved by a technician first, if you are an Intel® technology provider you can just go ahead and replace the unit without any approval by a technician.
