Question Fans speed values/Mortar b660 - CPU frequency jumping i7-12700

[nate12]

Hi,

I recieved my pc this week. I7-12700, msi mortar b660, noctua 15 cooler.

At the start it was very noisy. I removed one fan from Noctua(not the middle one) as i was told it will be more than enough anyway but noticed it was the front fan that was making noise as it was working at 1000+ RPM from the start. I started to play with bios settings and i made this values. Its quiet, problem solved. But 2-3 times by now i noticed that sometimes my pc started to lag a bit for like 3-4 seconds during regular work. I dont have anything connected, just doing browser things. Wont have GPU here as well.

Not sure if it matters, maybe its normal but CPU frequency is jumping from 1500 to 4600 all the time in matter of seconds. During no load at all. Doesnt seem fine. Pump Fan1 is the fan in front of the case. Sys fans 1 and 2 are the one in the back and one above Noctua. Noctua fan is running even though it shows 0 rpm here. One time i saw values like 400-500 rpm was when it suddenly went to 50'C with temperature and then RPM value was visible in this msi center.

Can you help me out setting proper values to make it super quiet like now but to work normally? Thanks!

CPU reacts and frequency (also by core) change with load which in turn gets heated and that's what fans react to and adjust speed.

I know that.

My question is if that values i added in Bios for Fans are ok(i adjusted it a little bit randomly, just to put lower speed, but maybe thats too much)

And is that CPU Frequency change is normal with such jumps every second during no load at PC. Lets say 10 tabs in browser open and thats it. As posted CPU Usage is 1-2% but frequency is jumping every second from low 1000-1500 to 4689. With this high numbers most of the time. Its weird to me that frequency is at max with basically no load, but maybe thats how its should be. I really have no idea here.

There was a reason why out of nothing twice by now, while having opened tabs only in browser and nothing else i had this 3-4 sec's lag when everything stops and i cant do anything. It happened only twice but within 4 days its strange so trying to find reason for that.

I have 2 monitors connected one with Hdmi, one with display port

You have to find which process is pushing it, it's not going to do by itself.

Please leave it ser. I welcome every help but you are not answering and not sure whats the point

Back to my problem. Lets leave fans speeds for now as i cant find help for this anyway, can anyone tell me if that CPU frequency jumps are normal? As mentioned earlier, its brand new PC. All i have installed is mail client, antivirus and tabs in browser. Nothing more and its basically at max frequency all the time.

Maybe its fine and it should work at 4689 Mhz all the time even with no usage?

Just managed to found few topics about it and think its normal and called Intel speed sth tech.

Also similar question about Ryzen : Normal for Ryzens, which slow down individual cores when idling. If your frequencies aren't jumping all over the place while gaming or stress testing the CPU, I wouldn't worry about it. :

That's what I was trying to tel you. Frequency is dynamic, each core can run at frequency 0 Gz (sleep mode) up to it's highest boost/turbo speed depending on the load posed by OS and software. Result is change of voltage used by every core so that causes more heat which sensors pick up and adjust fan speeds accordingly.
It's not a fault, that's how they are designed to work generations back.When you look at a program that records frequency that cane be either "Effective speed) where it shows an average speed of all cores or it can show just fastest running core. There are programs like HWifo for instance that can show each core by itself.
