Heat sinks won't do much unless there's a good heat conductive connection to the heat source, hence thermal paste. The chip's rated to 125°C, but as long as you're below 85 it should work without any problems. It's possible its life might be a little shorter due to the toasty hotness in your room, but nothing to lose sleep over. | |

Anyhow the heat sinks are just stuck using double sided tape so thats why I think it made no difference, ill get thermal paste and try again. Adding a fan would result in more current draw, ill keep that as my last option. I'm not worried about thermal throttling. I'm worried about the safety of the chip, if I leave it on for longer than 2 days and if the temps keep rising I have nothing left to do. | |

Your setup looks fine on paper, aside from the ambient temperature. 40°C is hot. Hot hot. With only an 18°C differential between your CPU and the air I'm not entirely surprised your heatsink didn't do much (although I might check your thermal paste and mounting). Thermal throttling doesn't kick in till 85°C, but if you're worried you might try a fan to wick the heat away a little faster. | |
