I am using prime95 small ffts for thermal testing. After 15 minutes the hottest core hits 71 degrees Celsius. What temp would you consider the maximum safe temperature? Thanks!
 
Solution
Safe temps are mid 70s always for haswell, so as long as you don't go above 75 you are officially good. Max temps are at the 82 mark, but generally you should keep it lower.
