Question maybe too worried....

[Ghostdog275]

hi all


I have some "problems" with my PC or I’m just to careful/afraid. I hope I can get some answers here because I can't find them anywhere I know that it is very specific for different systems. Maybe they are dumb things what I’m asking
let’s say I am definitely not a IT specialist. this is just a hobby for me.

I build my own pc and this are the specs and parts.


corsair crystal 680x case.
corsair 240 rad
corsair 360 rad
corsair xd5 pump
corsair xc7 cooling block
ASUS tuf Z490 plus MB
intel I9 10900k
corsair vengeance rgb 32gb
1000 watt psu
Samsung 970 evo
Asus NVidia rtx 3070 ekwb

Water loop is going from pump to CPU to 240 rad then GPU and to 360 rad then back to pump.

The “problems” I encounter are:

The CPU is jumping around when pc is in idle state from 800 MHz to 5100 MHz
I can’t find a reason why it’s doing that. Temps are fine in this state around 28°C to 30°C. no programs or tasks are open. does anyone know why it’s doing that?

And the second “problem” is when I start a benchmark (doesn’t matter if its cinebench or 3dmark or some other test) it will go to about 65°C to 70°C and stays there. so that seems fine.
But when I’m gaming (like red dead redemption 2 for 4 hours at high settings) it will go over 70°C to around 76°C sometimes hitting 80°C or over. Water temp is around 40°C at that time.
Water temp is going slowly up so I think the water block is mounted correctly. i don't know what temps are normal for this CPU and when you go looking around the internet there all different....
I tried to down clock the CPU but it going down to much like from 5117MHz to 4580MHz and I’m not so good with the bios setting so I don’t want to screw up my pc.
If someone can give me advice or answers thanks a lot.

CPU temperature being what is jumping around - correct?

What about GPU temperatures?

Use Task Manager and Resource Monitor to take a closer look at what the system is doing when the CPU temperature (and GPU as well) jumps around.

Use both tools but only one at at time.

Also use Process Explorer (Microsoft, free).

Question:

"Water loop is going from pump to CPU to 240 rad then GPU and to 360 rad then back to pump. "

Is that a supported loop per the manufacturer's documentation?

I think he is referring to the clock speed, not the temp.

Is your Widows power plan set to max performance or balanced? There is a setting in there that allows you to set the min and max processor state. If you set them both to 100% it won't fluctuate. There's nothing wrong with the clock speed fluctuating, it keeps temps down instead of running at full speed all the time.

it is the clock speed jumping around and temperatures are fine at idle.

and there is no manufacturer documentation for the water loop it's a custom build.
and i did use task manager while checking the resource manager but it has no task and cpu is at 1% load and still jumping from like 800 MHz to 5100 MHz.

power plan is set to balanced. and i will try to find that setting you mentioned.
thx

Its absolutely normal. YOU didn't open any programs, but that does not mean Windows hadn't. In fact, because the system is free, Windows tasks are bristling with activity doing only-microsoft-knows-what. In Windows the load on CPU is never zero.

But when I’m gaming (like red dead redemption 2 for 4 hours at high settings) it will go over 70°C to around 76°C sometimes hitting 80°C or over.

There is a difference between running a 15 min test and putting load on CPU for 4 hours. I'm pretty sure if you would run the benchmark for 4 hours it would hit those temps too.

Open Process Explorer, leave the window open but drag to one side so you can watch what is happening when clock speeds jump around.

Observe during testing, gaming, just sitting idle.

Once you have sense of things you can customize the Process Explorer Window as you chose.
