I want to put Ryzen 3600 on Asus prime B450M-A as it has the same VRM (4+2 phase) as TUF series but without heat sink. Will it run properly on daily workloads like Video Editing ? And What VRM temps is normal ?
That board should be fine. The ASUS A series boards have always been very good quality. Usually they are similar to the ROG boards with similar quality components and VRMs but just without the gaming specific features and bling.
