Is there any REAL danger in running the CPU at 95*C for a long time?

[Jaxder]

So I'm running a giveaway for my buddies in my discord, whoever has the most Folding At Home points by the end of the month gets Discord Nitro, and each month thereafter whoever has the highest will get Discord Nitro. Folding At Home is super easy to install so...great, cool, awesome.

NOW that all my friends are running Folding At Home, a couple of them are asking about sustained high temps on their CPUs (they really want Discord Nitro I guess), my buddy's R5 1600 peaks at 95*C and presumably it's staying up in the low 90s.

My question is:

Is there any REAL danger in running the CPU at 95*C for a long time? I understand that it causes wear and tear on the CPU, but other than shaving a few weeks off the lifetime, is that kind of temp going to cause sudden problems?

max temps for ryzen, to my knowledge, is 90.

That doesn't answer my question. I understand what the maximum acceptable temperature is (according to AMD's site, its 95*C), but does sitting at that max temp for a sustained amount of time (lets say...16 hours a day for 5 weeks) actually cause damage to the CPU?

no one can answer that question, as people who cares about temps run their chips below 80c

 

but i've had an intel chip running at 99c 24/7 for 7 years (not exxageration), and it didnt die

sandy bridge CPU, though, not zen 1

have you tried watching the techquickie video that addresses "safe temps"?

while having your cpu sitting at 95 isnt gonna fry it, there are some downsides.

refer to this if you havent already:

besides being a sign that they need to repaste their cooler, no.

In theory, no.  My understanding is the engineers set power/temp stuff so that the cpu can’t really hurt itself.   In practice of course the engineers never got to test for X years so it’s hard to say definitively.  One advantage of 24/7 use is there less heating and cooling, so a chip run at a steady temp may do better than one that doesn’t even told that steady temp is higher.

Technically, and generally speaking, A cpu's usable life span is 4-5 years. So apps and programs eventually out grew single core, dual core quad core... ect ect.

The estimated life span for processors (most electronics) is about 10-11 years or 100,000 hours. (Full load)

Some electrical components are less in life expectancy of say 50,000 hours like old school capacitors.

 

According to the white paper, Ryzen CPU high temp alert is 70c. The motherboard should have the fan at 100% at default settings. Most boards max user input is 75c, then the fan is 100%. However the processor is designed to throttle at 90/95c and ThermTrip at 110/115c (board shuts off). 

 

Is it safe? As long as it's running within the default parameters, you can choose to run 95c consistently. But nobody would recommend it for the sake that most electronics prefer to run cool opposed to hot.

Assuming the CPU is running at stock and thermal throttling limits is turned on there is no harm other than the annoyance of loud fans

 

overclocked however is a different story, the life of the chip could be shortened significantly

good, but can you tell about other components in the laptop, i am assured that the intel amd and nvidia chips themselves can endure high temps but what about other company electronic stuff on the mobo that come through lower quality controls standards. I've heard things like peripherals failing on one side of the laptop or some capacitors puffing up but that is from over 5 years back. Do such things still happen that can render a laptop useless? I am talking about some dedicated expensive laptops starting from at least the Acer predator , Asus tuf, HP omen range through high end aorus, xmg and msi, but i think that this secondary electronic components are of similar quality in all these systems

thnx

Every component on the board have their own spec sheet with thermal limit listed, so you may look up each individual components for their specs

 

Say, for example, VRM MOSFETs usually allow up to 110c operating temperature (?) Or something around that

 

With that said, it's usually BETTER to run most things cooler if possible as it's definitely going to reduce the chances of things breaking
