Post the idle temperature of your CPU

[SchumannFrequency]

CPU: Intel Core i7 12700KF
CPU cooler: DeepCool AG500BK ARGB
OS: OpenBSD -current
WM: bspwm (manual tiling wm based on binary space partitioning)

The temperature is 24°C in the mid-season.
In winter, it is probably going to be 21°C or possibly lower (as I am fine with room temperatures around 15°C in winter).

Please indicate which CPU and CPU cooler you are using for your results.

28°C (room temp 22°C )

I have +- 22.9° C room temperature at the moment.
It may have been slightly cooler at the time of measurement, but not much.
Currently, the CPU sensor sometimes gives readings of 24°C. But often 25°C or 26°C right now.
The temp sensor values are not completely stable and sometimes fluctuate per measurement.

The air cooler seems to be able to keep the CPU +- 2°C above room temperature.
I have two 140 mm intake fans in my case that provide decent airflow.

With fan off: ~45 °C.
With fan on low rpm: between 35-40 °C.

I have to add, my RAM is at 4800 MHz, which lowers my VSOC to 1 V, which shaves around 10 W off my CPU power.

Perhaps the ‘thermal grease’ used is also useful to mention.
I had not used the thermal paste provided by DeepCool. I didn't want the thermal paste on a pair of scissors as I don't know if it is toxic.
Therefore, I used 'XILENCE Silver Tim'.
I have been using this tube for many years for all the CPU coolers of computers I build.

The 'XILENCE Silver Tim' thermal grease seems to remain perfectly usable many years after you bought it.

Quality of thermal paste may slightly affect temperature.

The hottest core becomes 53°C when rendering with Blender right now.
In winter, I may stay below 50°C under full load, with CPU rendering in Blender.

Thermal paste that is of really poor quality can produce big differences compared to the best thermal paste.

I mention it mainly for when people would get different results with the same cooler/CPU combination so you can fully reproduce my setup.

What I see is e.g. an 'AM4 - 140W load' with room temperature cannot be cooled better than 54.x degrees with the most expensive Noctua air coolers.
But for Blender (under Linux), I see that my system (Intel 12700KF) is currently reporting maximum 53 degrees C°.
The Intel 12700KF uses 190 Watt TDP under turbo (standard 125W) so I find it remarkable that this CPU stays max 53°C in my tests.

Intel Core i7-12700KF Review

After looking at the flagship Core i9 on launch date, this time we're reviewing the more mainstream Core i7-12700KF which is meant to do battle against AMD's...

www.techspot.com

For cooling we've gone with the MSI CoreLiquid S360 as it's the only official LGA1700 cooler that we have on hand and here we see that the Core i7 processor peaked at 79 degrees after 30 minutes of looking at the Cinebench R23 multi-core test.

Is the Blender BMW render 'redoing several times' then a much lighter workload or what explains the large difference in temperature that I see?

 

[DaemonForce]

Just an ordinary R5 3600 pinned ↗4.0GHz
Some MX-4 on a Koolance CPU-300 series (Pentium 4 era) gold brick and a fairly restrictive boi
3x120mm MBK fans in a nice quiet pull config ~30%
Room is 28℃ and climbs around 36℃ throughout the day. Stays a bit warm.

70℃ seems like a fairly good max load temp but I'm not happy with the idle temp.
Athlon box runs a little better and then that insufferable nForce chip and the QLogic card make everything way warmer than it needs.

The best part is that I once pulled the noisy 80mm factory CPU fan and anchored in a 120mm Cooler Master SickleFlow just to deal with the chipset.
The QLogic card gets its own generic 50mm and that took care of the card overheating and taking out the entire network stack.
Maybe someday I'll replace it with a low pro SolarFlare.

The thermal paste used makes little difference in how cool your CPU runs in my experience. It matters more with application difficulty, cleaning and longevity.

In general, I think so too. But in some rare cases, I think it can make a difference.
The very worst thermal grease can produce a difference of 9°C warmer than the best thermal grease.

Paste used is MX-6.
Current room temp is 26.6 celsius.

And by each core:

The maximum temps were after a 10 mins of Cinebench R23 multi loop.
During gaming it stays between 45-60 celsius depening on what I'm playing.

I use multiple types of cooling..... this is kind of difficult for me, so these numbers are from memory because cooling is not a consistent thing for me.

Air cooling stock 14700K idles 40c (ish) and will hit 100c with any type of full load. (my cooler isn't made for this!)
Water cooling ambient, stock 14700K idles a bit better about 28c to 30c and "may" reach 100c load with AVX2.
Water cooling CHILLED idle temps as low as 4c with a 5.7ghz/4.6ghz OC and a max load temp of around 88c (ish)
DRY ICE cooling, Acetone in a Venom LN2 pot, idles reach as low as -65c to -65c depending on the cpu configuration 6ghz all core / 7ghz 2 cores.
LN2 I haven't used in a long time. But idle as low as -174c with a max load of not much higher. Not using 14700K here, but Phenom II or FX processors.
Last time, LN2 might have been socket 1366 a couple years ago. About the same temps as the FX/Phenom II runs, idles about -174 with venom pot.

Want to build an SS unit some day though. Processors are a lot more fun in the cold weather.

In the 40s I guess (Ryzen 5600/Be Quiet Pure Rock 2), but the real thing is of course

I have stuff on background

there is no such a thing as idle on a modern Windows machine connected to the internet, and even if it was it's not an interesting number to have IMO, because if your computer isn't doing anything it probably shouldn't be on.
