How hot is too hot?

I recently popped the heatsink (stock aluminum garbage with the black spring poles) to check the core (didn't want to flash a r350, luckily it wasn't), then cleaned it with alchol, applied AS Ceramique, etc., usual process, and re-installed the heatsink. Through testing after the flash I found the heatsink, while not scorching, is enough to cause pain if touched for too long, and it's much hotter, obviously, than before the flash. Is there a chance of damage if the stock heatsink is left on? My case stays fairly cool, and there is a side panel fan blowing directly at the card. What worries me though is ATItool displays artifacts shortly after attemping to find max mem or core, forcing a restart, but I've noticed artifacts in no other application or Artifact Tester.

Thanks.

EDIT: Fogot to add there is no LM63 chip on the PCB, so I can't check the temp of the core.
EDIT 2: Ack, meant to post this in Cases & Cooling. Oh well.
 
Somebody correct me if I'm wrong, but it would seem that the heatsink being hot to the touch is good thing (a sign of better heat transfer).
 
True, and something I had hoped to attribute to applying the AS instead of keeping the stock silver stuff, but the artifacts after the flash is what worries me.
 
You might want to consider a better HSF before doing anything to the core. Those R350 and R360 cores run very hot and it's always good to get a better HSF if you want to find the real potential of it.
