Ruined 9XL Motor?

Well i didn't keep a check on the temp but i'm geared 16/46 with an RCM heatsink, u could put your hand on it after running an 8000 mah lipo. there was no smoke. The motor has been ran about 8 times i'd say on 4s 6 and 8000mah packs. This is a Nemesis XLT-4 which i was told is roughly a 9XL if that makes a difference. Before i knew better, i ran it twice in an G3r revo on 5s 6000mah pack geared at 22/72.
