i7 8700k stock temps cryorig r1 universal running 70C

[NuggetBox]

My i7 8700k is running at the stock speed of 3.7GHz with a cryorig r1 universal cooler on top of it. I heard it was one of the better aircoolers and that it was keeping even overclocked processors cool. Though under load, my cpu is running at 70C, isn't this a bit high? Should I worry?

While the base clock speed of the 8700k is indeed 3.7GHz, in practice it actually runs at 4.3GHz as its all core TurboBoost, and getting about 70 celsius at stock settings is not uncommon. You might be able to get temps a bit lower if you turn off TurboBoost, set your multiplier to 43 and manually adjust your voltage to try to get it running at a lower voltage than the motherboard's auto mode. If you have an ASUS board, you have to watch out for Multicore Enhancement, as it is often enabled by default and will run all 6 cores at the maximum single core Turbo of 4.7GHz, and it does this by pumping a lot of voltage through the chip, likely more than actually necessary to ensure stability, and this will also lead to high temperatures. Other vendors have similar features, but usually don't have them turned on by default.

I cool my 8700k with a Deepcool Assassin 2, which is a large air cooler similar to the Cryrorig R1, and under 100% load my temps are in the high 60s to low 70s when running at the stock 4.3GHz all core turbo with auto voltage. It's a hot running chip, and there is a reason high overclocks tend to require a delid in order to keep temperatures under control.

NuggetBox,

70°C is not at all high.

Here's the operating range for Core temperature:

Core temperatures above 85°C aren't recommended.

Core temperatures below 80°C are preferred.

Core temperatures increase and decrease with Ambient temperature.

Idle temperatures below 25°C are generally due to Ambient temperatures below 22°C.

Highest Core temperatures occur during stress tests, rendering or transcoding, but are lower during less processor intensive workloads such as applications and gaming. Core temperatures can vary greatly among games due to differences between CPU and GPU workloads.

Thanks for letting me know of this, I never actually stumbled upon the fact. I'll look into that further.

All I really want to know is if my CPU is in any kind of danger to a shorter life-length or such. Some tells me it is, some tells me it isn't, I just want to make sure!

70 isn't a dangerously high temperature, most locked Intel CPUs are going to run at that temperature when under full load using the stock cooler and they last for years and years with the motherboards usually dying before the CPU does. The only bad part about getting a 70 celsius temp on high end aftermarket cooling at stock speeds is it means you don't get a huge amount of thermal headroom for overclocking.

Picking up on the thread here once again. I found out that it was in fact running the boost up to 4.7 GHz and I'm fine with that. What I wanted to ask this time was if it would help by adding more exhaust fans to the case? I'm currently using the h440 case from NZXT and it came with 4 pre-installed fans. 1 140mm in the back and 3 120mm in the front. It does however have support for 2 more fans at the top. Since the hot air rises to that part of the case and that is where the cpu-cooler is located I thought that it might help temperatures and general airflow of the case. Is that a good idea?

I'm using the same h440 case an i7 8700k with Cryorig R1 Universal and I installed 2 140mm fans on top sucking air out. I got temperatures of 68c max so far. I read that h440 is running a little bit hotter than some other towers, so I would say it's totally ok. And by disabling Turbo boost in BIOS i never passed 60c
