Xbox 360 slim no RRoD?

Does Microsoft already fix RRoD problem on Xbox 360 slim? I check on several website and i found something interesting that Xbox 360 slim only shows "Green only" on Ring of Light as shown below

Does it means no RRoD problem again on Xbox 360 slim? or Microsoft just move the problem? meaning maybe we will not see RRoD problem on Xbox 360 slim but we will facing with new problem? 

Xbox 360 slim have several differences compare with old Xbox 360 slim to avoid RRoD problem.

1. Air circulation system : Xbox 360 slim fan have difference mechanism from the old one whereas Xbox 360 slim  blow head sink with fresh air, this will make head sink cooler rather than throwing hot air into open air. And as we know all computer PC use this mechanism
2. Overheat warning : Microsoft will not allowed Xbox 360 too hot. A warning will apprear when Xbox console becoming too hot, this will make your console stop working
3. GPU and CPU : as we known before Xbox 360 slim combine GPU and CPU into one chip and the most important is this chip equipped with good head sink, not like old Xbox 360 whereas GPU chip only use small head sink.
