hi, I have this problem also. My EVGA logo is now piss-yellow due to a discoloring of the LED strip. I guess I'll call the 888 number later to see what they say.
Side-note. I bought a 3rd party strip from Amazon for $3, and it also turned yellow after about a week. The actual transparent rubber-plastic stuff that covers the LED device has discolored. It's browning like most transparent plastics do after 10-20 years of age... only it's happening in a week.
