you have to mod some fans on the adapter because HTC couldnt be bothered to do it themselves.
As for USB AA cables, you generally want to minimize movement between the adapter and the battery - one way would be to mount the battery like a countermeasure. I bought some of those heavy duty braided ones off of amazon and they seem to be doing much better than regular ones that were toast after about a month.
Also its taxing for CPU so expect some CPU heavy games to take a hit.
