Slow 4924 fan

Have a 4924 with no known history other than the shop replacing U7100, u7501 and u7200. Had no fan spin, checked joints all around the aforementioned ic's fluxes and flowed them, got this weird hesitation, then slow fan. Once the board cools, it won't start again. Heat around those chips and it starts the hesitation fan again. Ideas?
