I noticed it within a week or two. Took a pic, then took another 2 weeks later and it had clearly moved. It looks like the putty is just wriggling it's way out altogether.Wow! Did this happen to your unit? Were you able to replace it under warranty?
I refuse to be Gigabitten again lol. I just returned it within 28 days as no way I'd get a warranty claim as they are saying there is no issue.
Real shame as the card and cooler were fantastic
