[SOLVED] Overclocking a GT 610 without fan, is it safe?

[dmff_007]

Hey! Is it safe to OverClock my GT 610 2GB without a fan?
As the GPU doesn't have a fan, I can't control the fan speed in the MSI afterburner.
How hot should a GT 610 run while playing games anyway?
CPU has a fan, and the case has a fan too (Model Tacens ALU III)

GT610 is not a gaming card but should still have a ~90c ceiling.
