CPU at 40°C While idle/browsing the internet?

gabrieltkd95 · Jun 16, 2016

My CPU is an i7 6700k (no OC) and my cooler is a TITAN Hati. I am getting temperatures arround 40° sometimes while browsing the internet, its not a constant temp, normally it is at 20° but from time to time starts to oscilate the temperatures. Its like 20°,35°, 20°, 40°, 25°, 38°... just in a couple of seconds and then it returns to 20°. The thing is while i'm playing games like The Witcher 3 on ultra settings the temps are arround 50°. Its fine?

Yeah it's fine. It just happens during brief load times (transients) before the fan has time to speed up.

Gabe, here's all you need to know. If your PC goes above 80°C in any situation, you've got a problem. If it doesn't go below 80°C in any situation, you're fine. So if you're at 40 Celsius idle, you're OK, but if you're hitting like 90 Celsius at load, you've got a huge problem.

Not really, those Intel chips can go far above 80C without a problem. So can most all GPUs. 90C is not a huge problem even.

Huh, I must be thinking of the 4790k then, I assumed they had a similar max temperature. I didn't mention GPUs though, but yes they can generally go higher than CPUs

turkey3_scratch · Jun 16, 2016

The 4790K should be fine, too. I'm pretty sure those chips don't throttle until they hit 100C, but don't mark my words in stone.

xXCrossfireXx · Jun 16, 2016

Well turkey, I wouldn't want my 4790k running above 80°C, I mean it can handle it for sure without thermal throttling, but it's definitely not good for the CPU

No damage is done to the CPU even if starts throttling. The reason it starts throttling is to make sure the temperature doesn't keep rising. It it continues to rise, then it shutdown to prevent damage. No damage can be done to a CPU in any noticeable way to it's lifespan as long as you don't intentionally try to fry it by increasing the voltage. Same goes for GPU's.

Suzuki@1473780084@1473780163 :

So you're trying to argue that it's OK if your CPU hits 90°C, and it won't even reduce the lifespan?

turkey3_scratch · Jun 17, 2016

CPU lifespan is so high anyway as is. Maybe it'll go from 15 to 14 years. You just don't hear of CPUs dying commonly. Your CPU will be outdated long before it dies.

Suzuki@1473780084@1473780163 · Jun 17, 2016

My laptop CPU has been running close to 100 C for about 5 years like every other day for hours and it's still working. I don't believe that as soon as one hits 90 C, you instantly reduce lifespan by a year, otherwise I would be at 0 by now.

Suzuki@1473780084@1473780163 :

I was not inferring instantly, I'm talking about continuously running it at high temperatures. But even then it's negligible.

Suzuki@1473780084@1473780163 · Jun 17, 2016

Yeah, I do VFX, and I render a lot of things on the laptop so that I can work on my main desktop, and my laptop haven't failed me yet.

I did ask Intel about this a while back because this question came up earlier on forums, and the Intel rep said that there is no noticeable reduction on the life span even if you reach 105 C to which most Intel CPU's shut down, but that people are confusing the performance decrease with the life span.

People said the same thing about overclocking, that it reduces life span, I didn't ask about this to the Intel rep, but I do know that I've run an overclocked FX CPU at 1.4V for years, the PC is on about 9-10 hours a day, no power saving or anything, always at 4.6 GHz.

Suzuki@1473780084@1473780163 :

Yeah, I suppose the voltage increase would reduce lifespan (if at all) more than temperatures.

xXCrossfireXx · Jun 18, 2016

So if this is all true, why does everyone else say to keep Haswell and Skylake under 80°C?

turkey3_scratch · Jun 18, 2016

xXCrossfireXx :

Because they just make stuff up.

Yup I'm out, later people
