did he put any load onto the CPU like played a game or ran a stress test? It would make sense since it got so hot but otherwise its fine ivy bridge had 110C Tjmax from what i remember and he probably shaved off a little life span but its fine next time just tell him to use thermal paste
it should be fine if there was no load on it its not a problem it is an issue why it was running so hot without any load on it even if it had no thermal paste maybe the voltage is too high? The one thing that will for sure damage a CPU and significantly reduce lifespan is too high voltage do you know what it was?
@psychoman on Intel CPU's if you use HWmonitor CPU package temp is the hotspot temp or Tjunction. Same for FX from what i remember i dont know about Ryzen theyve got a lot of temp readings from what i've seen but yeah ivy bridge was "safe" up to 105C,110C kinda how Apple runs Coffee Lake at 90-100C constantly
and then throttles them under load in their laptops. Obviously not ideal but CPU's are made like workhorses especially those older sandy bridge,ivy bridge ones they could go up to 1.5V+ at 5Ghz if you got lucky they were built like tanks but running that hot will reduce lifespan from i dont know 20+ years down to 10ish
this is pure speculation as CPU degradation goes from the end of the lifespan and they are typically rated for 20+ years at stock so even heavy overclocks live a long time provided you are lucky and dont damage the CPU with high voltage which is entirely possible
As far as I know the CPU would shut down the system if it went over the limit. My friend once "gamed" for months with massive thermal throttling because his CPU paste got knocked apart when transporting the PC. 100'C for ages. His CPU was a 2nd gen i7, don't remember the model. Only recently did he upgrade to a 9900K, but not because of a failure or anything.
The CPU will be fine, I think.
@david988 yeah thats absolutetly fine nothing wrong with that but just buy like 8G of mx4 itll cost you like 8€ it should last for like 30-50 applications or 4G for 5€ or if you dont have that one get something similar its always good to have extra thermal paste
Every Intel CPU since Core 2 duo and newer have protection from overheating so if CPU reaches near limit it will lower its speed or worst case turn off PC to prevent fatal damage. Keeping temps high (~100C) for long enough will shorten its lifespawn but for half hour or less it should not be a problem
Hell I got a Core 2 Quad Q6600 from a friend who been running that CPU at max temperature (because of broken cooler) for a year until he decided to sell PC since it was running super slow :D
New thermal paste etc. and it runs much better :D
Also performance stays same as the other Q6600's
