I've been running my system (p4t-e, P4 1.7, 512 RD, Radeon 8500, etc) for about 4 months. My temps are similar to yours MBM reporting around 39-42 C depending on use. Board has been rock stable. I have all stock HSF right now (although I have lapped and re-set with AS3).

People seem to think 40C is okay.
