yes room is hotter of course. I checked the gpu fan it looked okay. wasnt very dusty.
there is about a 15c increase on gpu temp . when i first tested the temps back in november, the card would run at 77C at bf3, the max temp seen was 85 when the fans were not working at max rpm.
Now it runs around 90-95. and max is 100C
if you don't have AC, expect hotter temps in the summer then in the winter
while 90-95 is warm for a GPU, it's still well within spec. you can always download MSI afterburner to increase fan speed. I would also double check all the case fans to make sure they are working properly.
