Hello All,
If you are experiencing a grinding or rattling noise coming from your new Kraken, Please check your CPU_FAN voltage in bios. It has been noticed that some newer motherboard automatically change the CPU_FAN speeds when installing the unit to less than 100%. Please manually change that speed to 100% only and that will fix that issue.
If you still notice this issue, please submit a ticket for more assistance.
This fixed the problem I was experiencing with my X61! I was about to request a RMA, but glad I checked this first.
This made absolutely no difference.
