My 6500 has started to make the worn bearing noise on both case fans. Seems like the KD1208's are now discontinued/obsolete and no longer available on Mouser or Digikey.
Digikey is recommending the Delta Electronics with similar spec.

Specs look good, so unless anyone has any recommendation on another brand / model I will go ahead and order a couple of these.
Just wanted to check with y'all before I pull the trigger.
