ATI Video card question. x1300 pro AGP 256mb?

I just bought this card a few weeks ago and Im concerned about its temps while running. I have a AMD64 athlon 3400 @ 2.4ghz speed. 1024mb ram and a 350watt powersupply. The PC tower gets excellent airflow and I have 3 fans blowing out air from the back. I've checked my cpu wattage with a watts calculator online and I am running well under 350watts. I think i clocked in at 265watts under full load. Thus, i know I'm not killing my powersupply. I was playing FFXI for about 1hr and 30 mins and noticed the tower was running really warm. I checked Bios and the temp was @ 53c. Is this too hot for my ATI x1300pro AGP 256mb card? Will it cause damage?
