You have the original bios on your card.
But as for proper bios, any bios these cards have can be called proper, if it works.
If you are already adjusting the fan speed with a program, then there is no real need to update the bios. Especially if you getting a nice overclock like you have, I wouldn't mess with it, and keep using precision.
As for the temps (in general):
1- clean the card with compressed air if you haven't already.
2- Make sure you have good airflow in your case, and around your case.
3- if everything is nice and windy there, a reinstallation of the thermal paste might be in order.
4- And lastly, you might have to decrease your overclock for the summer months, as some do, due to to the increase in ambient air temp. But really, that card can take 75c all day, 90-95c then you worry.
For that overclock with the stock cooler, especially.
