Need advice around CPU temp

[ICIP77]

Hi all, long time PC gamer but first time PC builder here.

Recently built my first rig. I have a Maximus VIII hero motherboard with a I7 6600k CPU. Using a Phanteks PH-TC12DX air cooler.

Just a couple of quick questions about CPU temps - I will admit to being a little obsessed 😛
It's pretty warm/humid here - 20 degrees outside, probably 22-24 in here. At idle the CPU runs at around 26-28 degrees. Under load playing most games on Ultra settings it hits 45 - 54. Are those temperatures ok? Also I noticed when playing Starwars Battlefront that the CPU temp is much higher - it hits 64-65. Immediately upon exiting it returns to under 30. Is that just Battlefront being tough on the CPU?

Monitoring temps using Hwinfo64.

Thanks in advance.

Temperatures are good. No need to worry.
Only thing bothering me that you said your CPU temp goes down from 64-65 to 30 immediately. This may indicate your cooler is not properly installed.

Off topic, 22-24 is not warm. I have 32 degrees C right now outside. And summer has yet to come in my country. Which will bring with it close to 40C temperature and 80-90% humidity. Hurrah my tropical country.

Sorry - yeah it's not tropical here but it is 10 at night and the heat/humidity doesn't drop.

When I said immediately I mean within probably a minute or two. I hadn't even thought the cooler might not be seated properly.

How do you manage with your set-up with such a high ambient temperature?

If it takes a minute or two to drop to 30C then you are good. No need to worry.

I have cryorig H7 for CPU and get away with negative pressure. My under load temp remains in mid 50s to mid 60s in summer.

Just played Battlefront again - running 60-64. No worries. Dropped out and immediately showed temp of 36 before slowly dropping to 26-27 over a few minutes. Is that normal? As I said a little obsessive over this.

Also on Hwinfo I have several CPU temps shown - which is the most accurate? I have CPU package, CPU max, Core max all listed under Cpu - intel core. Plus listed under the motherboard I have CPU and CPU (PECI) - all are slightly different. Which is the one to watch?

Start a stress test and see if your CPU temp rises suddenly. Like from 30 to 60 in a second. If it increases gradually then you are fine. If it indeed rises sharply then your cooler may not seated properly. Reinstall it.

All temps you have on HWinfo are accurate. CPUs and motherboards can monitor individual core temps. Generally core#0 will have higher temp than other cores. CPU package temp is the temperature of outside if CPU, figuratively. Literally package means the actual CPU you install in the socket, the square you can hold with the metal cover lol. Max temps shows the max temp HWinfo recorded at the current run. Min is the min temp it recorded. CPU(peci) ia the temperature that cpu itself tells it has. Other data are from various sensors. They all will be slightly different, plus minus 1-4. If you want only one thing to monitor, go for CPU package.
Also i assume you monitor the temps on the sensors screen from HWinfo. You can log the readings and watch them in a graph by a addon called GenericLogViewer. So you can really see when your temps are rising, how gradually it is increasing. Download from this page - http://www.hwinfo.com/addons.php.

And don't sweat over the temps, they are good. Only thing you should check if the temp jumps suddenly under load in couple of seconds. If it rises gradually, then no need to worry.

Your temps are normal. Above 80 degrees is a danger zone

Just gonna add to this. My 4790k was hitting 100 degrees with a normal voltage and great cooler (Noctus D15) in Prime95. I don't know if this happens in Prime95 with Skylake too, but OP, I'd use OCCT as a stress test if I were you.

Thanks both of you - will try and run the stress test tonight or tomorrow and will see what happens. Sitting nicely at 27 on idle at the moment - peaks for like 2 seconds at 40 when I open new applications like steam etc then immediately drops back down. It was my first time installing the cooler so I wonder if there is something in that. I know the temperatures are pretty good but the rapid fluctuation was bothering me too. Will let you know how I go.

That was interesting - just ran the OCCT stress test - was only able to run it for a short period of time as was interupted but the same thing happened. Watching CPU temp on Hwinfo - the temp jumped from mid twenties immediately to mid sixties. No gradual increase. Sat fairly stable there until I had to quit and then immediately dropped to 25 odd again. NO incremental change just big jumps. However watching the CPU temp on OCCT I got this a lovely graph showing a slow temperature rise from 28 odd to 41.6 over the same period? Upon stopping the test the reverse occured - slow cool down to idle levels - this would seem to make much more sense to me. Does this suggest to you that the problem is indeed my cooler and I should re-seat or is the OCCT measuring something else?

No need. You are good. Your temps are good and there can be discrepancies between two software reading temp from different sensor.
Just start playing games.
