65c too hot for prime 95 with 4.2ghz 8150?

Hi, im getting 65c with prime 95 many people say 61c is my processor limit before starting to break down.

It shouldn't degrade at 61°C. If anything, CPUs can withstand much higher temps than that, but many people like to stay under a certain number. (For me, that is 80°C under full load w/ my 3570K).

With your CPU, people tend to see 61 as the temp limit. This does not mean it will degrade, but risk damage. On AMD's website is not specific as to whether this is a socket temp or core temp, but try to keep it as cool as you can.

The (C) in the "max temps" row is inferred to mean the Core Temperatures; I think AMD says this somewhere on their forums. (I believe it is in the same place where they explain the difference between Socket temperatures and Core temperatures.)

Along with every other tool at your disposal, the more you use something, and the harder you use it, the shorter its life span will be. Running at above 61C won't magically kill your CPU on the spot - usually - but you're certainly placing a lot of stress on it. Since no two CPUs are truly identical, it could be that you could run the next two years without a problem. Or it could bork next week. Regardless, CPUs are made up of semi-conductors, and as a general rule, for ever 10C difference in temperature a semiconductor operates at, you either half or double its life. The fact that these things run years is a testament to the quality of their craftsmanship.

Heat is only half the story, though, as voltage is another leading role, which has a direct impact of the amount of heat.

I have my voltage around 1.3 dont know the exact amount but i dont think i could lower it anymore and have it stable.

Thats the prime 95 temp that i left it on for 2 hours, i never go above 50c while gaming.

Your voltage is good, very good actually, given that frequency level. Above 1.4 is when you have to start getting wary, and towards and beyond 1.5 one definitely needs to be cautious.

What case are you using, and how many fans do you have installed in it?

Corsair 600t White, 1x outtake 120mm ontop ( cant find a replacement 200m) 1x 120m outtake at the back 1x intake 200m fan on the side, and a 200m intake in the front.

That should be enough airflow. Other than somehow else affecting the ambient temperature of the air, I can't think of any other way to reduce the heat of your processor so you don't have to worry about max-load temperatures.

I'm running 4K @ 1.13v @ ~81c on Prime @ 35c ambience. Unfortunately no way i can safelly go any higher.

Edit: I thought it was a thread about 2500k. Anyway, my processor in that one.
