What temp does your 9th Gen i7 9700K run at?

Specs: Windows 10, i7 9700K
So, I just upgraded my PC from an i5 to an i7 9700K. I'm now watching the temp very closely to make sure it's working normal. Right now, my computer is at an idle. Some reason the cpu is showing 30% usage. But, the CPU temp is 65 C. I ran some stress tests. I just ran prime95 on it and it didn't get above 70 C. It just seems to be running hotter than the i5 did, which makes me a little nervous. I'm not overclocking it and I don't plan to.

Right now it's idling at 46 C.

What you didn't tell us is which i5 you had, what CPU cooler you're using, what type of thermal material you used, or how it was applied. Your i7 is a 95W CPU & its max temp (T_junction) is 100C.

I don't have an i7 but I did a quick search - idle temp below 40C, max temp under load under 75C.

"...if you have an Intel processor, you could say that a CPU core temperature of over 40-45-degrees Celsius while idling and/or a temperature of over 80-85-degrees Celsius while under full load is probably a cause for concern."

Ok, so I installed Core Temp. According to this, my Tj. Max temp is 100 degrees C. According to your link, that means the highest temperature allowed for my CPU. Currently all the cores are running 50 degrees or cooler. At this very second, between 39 and 41 C. My CPU is currently running at about 40% utilization. (Backups are running right now it appears and using up 20% of the CPU.) So, it's probably normal. Just being extra cautious right now seeing I just installed it.

My previous CPU was an i5-9600K. The new CPU is an i7-9700K. I used Corsair TM30 thermal paste. I think I applied it correctly. (Before this PC, it's been about 15 years since I built a PC...) I googled how much to put on. I put about a pea size amount in the center of the processor and then placed the cooler on it screwing it down.

Here's a link to the cooler I'm using...

CPU is now running around 10-15% and the temp is between 32 and 38 degrees Celsius.

So, not sure if this means anything... hopefully a fluke.... but I left my PC running last night. This morning the screen was black and unresponsive. I had to hard power it off. It booted back up fine. Event Viewer stopped creating logs after about 1 AM. But there were no errors thrown at the time.

No one really ever answered, what temp does your processor run at normally?

my overclocked i5 6600k runs at 24C idle@800mhz core clock and 0.750volt and 13watt.
my highest temp was around 80C with ~150watt load and my cooler = hyper 212 evo

I did however delid my cpu and replaced the thermal paste with thermal grizzly conductonaut liquid metal.This is something you cant do with the 9700k since the die is soldered to the integrated heat spreader (IHS)

also there is a misconception about using too much thermal paste. you cant really use too much, it'll squeeze out the side when you mount the cooler. (most of the pastes are not electrically conductive, so no worries there either.)

your higher idle temps can be caused my either bad distribution of thermal paste or just background processes which elevate the core clock/voltage making it run hotter "idle".
