Those are the actual locations of the RCS thrusters on the Orion capsule as of unit layout in 2013, as far as I know, no changes were made prior to the test flight in Dec 2014, so unless they make adjustments (not likely) that will be the active capsule for the foreseeable future. - - - Updated - - - I was having this problem as well for awhile until I installed RealHeat. This fixes a lot of my heating problems on launch. Try it out and see if it helps!
