Hey guys, Redbeard aka Corsair George is our case PM. He asked me to post this regarding a small issue we found with our initial batch of 650Ds. This is all the info I have at this time.

I wanted to let you know, we have discovered that early shipments of the Obsidian 650D seem to have a buzzing noise when the fan controller is used to run the fans at lower RPMs. We are currently analyzing this problem, and determining the proper solution. Later this month, we will be providing a free repair kit to all 650D purchasers that will correct this issue.

There will be a special page on our web site to obtain this kit, but in the meantime, if you have any questions, send an email to redbeard@corsair.com with the subject line “650D Buzz” and we’ll answer them for you. And, of course, I will keep you posted with the status on this issue.

Thanks again.
