as far as i know, there isn't, but i wouldn't use it, coz i don't want a temperature spike to suddenly shut down my PC during work / gameplay XD
Parts will start throttling once u reach certain temperature, so u can relax there, also, the hotter your parts are, the louder the fan will spin, so i think u'll hear them out just fine (also u'll feel the performance decreasing because of the throttling so u'll know it when the temps are too high)
u can also use apps like Rivatuner to monitor your parts condition during gameplay (with OSD feature
)
PC should have their own safety measure, or so i've heard, but i have no experience of my PC shutting down on it's own (especially because of temps so i can't say)
