Question Intel i7 14700k Arctic Freezer iii 420MM temp fluctuation

[Daani37]

Hi All,

I have an Intel i7 14700k (Stock) and my cooler is Arctic Freezer iii 420mm AIO. For some reason my CPU temps under no load just constantly go from 33-51 in a matter of seconds and they are constantly jumping around. This then causes the fans to kick in for when it spikes so all the time I am hearing the cooler fan go loud and back down and so forth.

I thought it might be the thermal paste as its been 6-8 months since I built this so took it off cleaned it and reapplied it using a spatula for even coverage but it still is the same. Constant spikes in temp without any load at all.

Any help would be appreciated. I am not concerned about the overall temp as I know 50 degrees is nothing its more the constant fluctuation within 1-2 seconds constantly.

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

List all attached peripherals.

Also not sure if it matters but I am using 1 8 pin CPU psu cable even though it has 2 slots and the AIO I am use the 1 cpu cable to control all 3 of the fans vrm cooler and pump rather then the 3 way splitter to control them seperate.

Just because you didn't change anything doesn't mean that the mobo is running the CPU at stock.

It sounds like the system has an aggressive overclock going on the single thread so the occasional thread that the OS runs heats that core up enough for the cooler to ramp up.

Show the bios screen that shows the cpu settings.

Hey there,

TBH, those spikes from 33-50 are typical of high core count CPU's at idle. I'd more concerned if your load temps were very high. What temp does the CPU get at load/gaming?

For the fans, you can use the bios to create a fan curve so the fans don't ramp up as aggressively.

COU sits at 60-65 when gaming. It’s mostly the constant fan change with the ram up all the time. Just doesn’t seem right under no load for the temps to increase 15 degrees in a second and go back down and just keep doing that.

You have optimization selected in the first pic, which could do all sorts of funny stuff, also everything is set to auto so whatever gigabyte thought is ok.
Also your projected vcore is above 1.5V which is pretty dangerous.

Maybe try disabling optimization and see what that does?!

Great will try that when I get home and post an update

It doesn’t let me disable optimization mode I can only access the menu by disabling Intel default settings from performance to disabled.

If it actually has intel defaults enabled then it's what roland said, your cooler is just too sensitive.

What about the projected Vcore being above 1.5V you said was pretty dangerous. Anything I can do to rectify that?

That was the word on the youtube at least on what was causing the issues, if it's intel default then it should be ok because everything else will be low enough to not make vcore go too high.

Intels default only has performance or disabled. Seems a bit bizzare.
