will frequent benchmarking damage cpu?

will frequent benchmarking damage cpu? max temp is around 85 (sry for asking,i am just curious and a bit worried)

 

[Supahos]

It can, which cpu do you have? Some that is the max temp, some that's not real close. There is absolutely no reason to constantly bench a cpu but it shouldn't hurt it. I'd steer clear of running prime for days on end or something, but a few mins at 100% load won't hurt anything.

85C is a tad warm....; I would only expect those temps running overclocked...

As long as gaming is around 60-69C, I'd not be running Prime95 daily just for fun....

Depends on what cpu you have, if you have overclocked the cpu and how mutch volts are you running it on.

 

[JackNaylorPE]

Well heat does degrade silicon chips .... specifically the insulating value between circuit traces. a stable OC under normal usage might mean it will last 7 years instead of 12 but as you've likely moved on in 3 or 4 no one cares. When setting up their OC, folks will generally stress test 1-3 weeks and then that's the end.

Depends on what you using. Since Haswell, I have stopped using synthetics .. only use RoG Real Bench now. I use it every 90 days to see if the system has slowed down in any way. So no, if you are not using synthetics every day, I don't see any harm... using application based benchmarks every cupla months is not going to be an issue.

my cpu is i7 7700k. max voltage 1.248v. i kept running cinebench these few days (just wanna get a highest mark). currently i dont plan to overclock it.

 

[kooiankeen]

is that ok to my cpu?

 

[mdd1963]

That temp seems high for stock clocked 7700K, in my opinion...

With Noctua NH-D15, my 7700K only hits 71-73C fluctuations with Prime95, and 64c in Intel cpu stress tests.

 

[lumineZ]

Your volts are just fine, but temps are high but not critical or dangerous if you ask me.
Most 7700k out there behave different since the stupid thermal paste intel uses between the die and heatspreader.

Take my 7700k and when I first got it I did a test run at stock speeds and stock volts.
I am using an EK-Supremacy EVO waterblock with a single 480mm hardwarelabs black ice nemisis radiator just for the cpu loop alone. ( pretty massive overkill cooling but hey I want the system to stay dead silent )
And just running AIDA64 stress test I hit 87 - 89 degree celcius!
So I got a bad thermal sample. So I had to delid to get the temps in check.

Others that has the same CPU with far less cooling capasity than me reports temps around 60-70 with the same stress test.

But atm you are "safe" but I would not like most already sayd run stress test after stress test, hour after hour, day in and day out.

 

[kooiankeen]

What do u mean by 'safe'? Can u further explain

 

[lumineZ]

What I ment is what I wrote after the "safe".

Think you mis read what I ment.

Just dont hammer the cpu at 100% none stop for 1 week. Every cpu out there will be damaged sometime even if you stay at 50 degree celcius or 90. Only difference is what?
The one at 50 lasts 12 years but the one at 90 will last 10 years or more.
Its just not heat that will determin how long your cpu will last, its also the quality of the many lanes, waffer quality, any nanoscopic weakness in the PCB or the cpu die.


Think of it like a car. Sure it will do 200 mph... but stay at that speed for a long period of time something will break.
