Is 99C for GTX 645 2 GB Bad when gaming.

I just got a new computer from HP. It has a GeForce GTX 645 2GB. When I do common stuff, like search the internet. My GPU rises to 40C, which I think is normal. But when I play games like BF3 on medium graphics, it rises to 90C and sometimes 99C. Is this normal?

I used speed fan but couldn't tell which fan was for the GPU. I am afraid I might have messed up some things in speedfan. Is there a way to set the fan speed to automatic/default.

I definitely could hear the fan getting louder when my games start to run, also the normal RPM for my 2 fans (which I don't know which is for which component) is 800 RPM. When I game, it rises to 1500RPM. My other computer rises to 2000RPM. Which has the HD 4250. I want to also make the fan go up to 2000 RPM ONLY if this temperature isn't normal.

  1. I'm not entirely sure about the temperature ranges for that specific card, but 90-99C is not healthy, period.
