What CPU temp is too high?

81 is still okay i believe, i've run my 3570k at those temps before and not had any problems. Ideally though you want to be staying below 70c. In real life situations you wouldn't hit those temps though anyway as stress testing always puts it past what it would run at in normal operations.
 
OK, cool, thanks Jay. I suppose stress testing is more designed for testing the stability of very well cooled machines, possibly overclocked. Will play a game/do some rendering and see the temps then. At idle the CPU is only 28.
 
Is it Overclocked? What cooler are you using?
It doesn't throttle till 90s so it is fine. If you are concerned then upgrade your cooler if you haven't already
 
I don't know why people keep using these stress tools, it torches the chip for no reason. You need to use the CPU in the same capacity as using it normally would.

The best way to tell if its stable is to do what you built you PC to do. Play games, watch files, movies, Photo/video editing whatever.....that will tell you if its stable. I doubt you'd get anywhere near 81c if you just used it normally.

its a pretty solid guarantee that your normal use isnt going to cause random issues.

some irl situations do put the same load, rendering for example. so there is validity in it. plus its quick and easy to fire up a test for 10 mins to test a clock.
 
its too high when you start to smell it burning:eek:

mid 80c id be happy with

its nice to know what load temps you get though with stressing software,folks only shy away from using them with recent chips is because they run too damn hot and you cant use them

:p
 
Takes about 2 seconds to hit the 90's on a stock haswell, so definitely a quick way to find max temp.:D
 
Not suprised its toasty then those nofans are designed for silent low to mid load like what would be used in a media machine hence the 80w max load. Your putting an 65w cpu through torture tests something this cooler is not designed for
 
LOL I dunno how many more times I have to say this but using Prime/Intel Burn Test on Haswell is a bad idea and not a supported way of testing a CPU. for load/temps. They put an unrealistic load on the CPU that cannot be achieved in real world usage. Use something like Passmark Burn In Tests/Aida64/Realbench that are all recommended by Intel/Asus/Etc..
 
the i7 4770s has a TDP of 84w, so if the passive cooler is rated to 60w, you have 20+ extra watts to lose and no fans to cool the headsink. maybe spend 20 quid on an aftermarket cooler with a fan?

my cheap cooler keeps this overclocked i5 below 80*c all the time and it only cost £23. can't hear it over the case and psu fans, so noise isn't an issue.

4770S is 65w... ;)
 
The T version is even cooler at 45w, a little lower powered but perfectly good for everyday use and coupled with something like a GTX750ti it makes a great low powered gaming system that can play the latest games at 1080p without fuss. :)
