Nah, it's not the GE90's - the PW40xx and Trent 900 777's are just as bad (before the GE90-115B was introduced on the 777-300ER/200LR, the 777 fleet was roughly evenly split between the Rolls, Pratt, and GE engines - it's since the introduction of the GE90-115B that GE has had nearly 100% market share). I think ECS noise simply wasn't a priority during the 777 development - they didn't think that the 'white noise' of ECS was that objectionable. It was the super quiet A380 that really brought the subject to the forefront.
