First pc are my temps normal and good to use? Daily

Hello, using asus 5ghz profile on the motherboard it automatically overclocked
The cpu to 5ghz for me.

When i turn on the pc i get a message from nzxt cam software that the cpu temp has gone over 80 degrees (celsius)
Then performance mode profile loads up and the fans go full speed to cool it down to around 35 degrees with dips
And spikes on an idle desktop screen. The dips and spikes persist. It never stays at exactly one temp. It will shoot up by 5-10, maybe more, degrees.

While gaming i was at 69 degrees then switched the aio software to respond to cpu temp, rather than liquid temp,
And now the temps are around 61-65 while gaming at 4k in paragon and rainbow six

these are the only 2 games that show temps on screen with nzxt software.

Aio is kraken x62.

What worries me is the warning on boot up about the cpu temp and the spikes in cpu temp on an idle desktop/start menu
.
This is my first build, so maybe most of this is normal. I dont know.

If anyone has any knowledge to share

Thank you.

Edit forgot to mention cpu is i7 7700k. Typed this on phone.

You assume that when you aren't doing anything on the computer is idle, that's not the case. Windows and many other programs are constantly doing things in the background that you can't see.

You can download a program from Microsoft called Process Explorer that will show you everything the CPU (and a lot of other components) are doing in real time. Click on the CPU column to arrange the CPU processes on screen

Here's the recommended operating range for Core temperature:

80C (176°F) Hot (100% Load)
75C(167°F) Warm
70C (158°F) Warm (Heavy Load)
60C (140) Norm
50C (122°F) Norm (Medium Load)
40C (104°F) Norm
30C (86°F) Cool (Idle)
25C (77°F )Cool

Many people buy cheep AIO coolers and expect miracles. They're about as good at cooling as mid to high range air coolers at best.

You need some software to stress you CPU and test you cooling system.
Core Temp
IntelBurnTest
Prime95

Personally, I prefer OCCT as it stresses the CPU and displays (and records) CPU load, CPU temp, CPU speed, CPU volts, and Memory usage.

Yes, i thought maybe that could be it. Things such as background processes. Thank you for the links. Do you know which program will display cpu/gpu temps in all games. The cam software doesnt work in every game and i have performance issues with these games. Also on the issues of the boot message stating my temp has gone over 80. Is that a safe boot temp. Thank you.

Auto overclock settings tend to use much more voltage than needed to run the clock speed that they are trying to run.

I would recommend doing the overclock manually, using manual voltage control.

Check the Kaby lake oc guide out, lots of good information in there.

Check in hwinfo or hwmonitor what voltage the cpu is using at load in the auto setting, then set in bios a little under it at that speed and go back and test the cpu in a stress test.

Continue lowering voltage until you fail a test. Then you know where the voltage limits are. Once you fail the test, bring voltage back up two notches and test longer.

Many 5ghz overclocks need a delid to keep them within a good temperature range even with good cooling. I have a custom loop with way more radiator space than needed, and without a delid I was stuck in the 90s at 4.9ghz, and couldn't hit 5ghz without throttling. After my delid, I'm in the mid to high 60s at 5ghz.

If temperatures are too high at 5ghz when stress testing, try lowering the cache ratio to 47x or even 45x... usually allows you to lower voltage slightly. If still too hot, lower cpu to 4.9ghz and run the same procedure to lower voltage to find the lowest operating voltage.

Thank you for that explanation. When i have some free time i will try this. Maybe safe wasnt the right word ha. If no damage will occur immediately from using these settings then i will leave it as is for a few weeks. FYI Rog cpu z
Stress test maxed the temps at about 76 .. but only had time to run it for a few minutes maybe less.

It's not the heat that kills CPUs, it's the voltage, Heat is just an artifact of current flowing through a wire.

The "wires" in a CPU are extremely tiny. maybe only a few molecules wide. Read about "Electron Migration". That's what kills CP{Us.
