Hi there, so i recently bought a pc and it runs perfectly fine not underload but as soon as it is under a little stress it hits temps of 100 degrees. i have tried undervolting through throttlestop but i didnt seem to have any results at all, i even set the undervolt to -250 to see if it would at least crash my pc but i got nothing. I followed a guide while doing so and did everything he did but i am just not seeing the results. i am wondering if there is maybe a setting i have selected that is stopping the undervolt from taking place? any help would be amazing
 
Even Intel itself says that 100C is totally normal for their toasters. Nothing abnormal there.

that is still on the upper end of where you want a cpu to be no? it does state on the website the maximum junction temp is 100 ? i would prefer if it ran at around 80 underload which i believe should be achievable with an undervolt and a switch to an aio cooler for it. i was just hoping to undervolt before i got the cooler as i dont want it to overheat in the meantime. i have a month wait for the correct brackets for my cpu cooler arrive as its coming from eu to Australia. i do appreciate the help mate im new to the whole half decent pc thing lol .
 
all you need to do is using a negative adaptive offset to whatever is stable (normally between -60 and -100mv)
100°C with an air cooler is often reached within a minute of all core load. the undervolt could shave off 10°C and allowing all core boost without throttling.

Well, you would need to underclock it as well which kinda negates the purpose of getting new hardware. Modern (especially Intel) CPUs are often clocked nearly to their maximum on factory, so temps are in line with that.

Or try that tip from the above post. 7700K was my last Intel CPU and not going to use their stuff anymore.

For me, too, the term "maximum temperature" means maximum, not normal, although you will hear various legends about it here.

from my research you can in fact undervolt these cpu's and get a pretty big drop in temps with no drops to performance what so ever which is why i was hoping someone here had some undervolt wizardry that they could drop on me ahaha. I in fact believe i have undervolt protection enabled in my bios and no toggle to turn it off which may be why i am suffering these struggles with my process but im sure ill figure something out.

yes that is what im thinking too. maximum doesn't mean optimum and after spending so much money on a set-up (yes i cheaped out on a cooler as im a noob and didn't realize how important it was lol) i expect it to run at maximum efficiency not temperature
.
 
Experiment with the IccMax settings. Example, the thread opposite.
i actually did give reading that post a try but ill be honest im not exactly sure where to even begin lol. i know that my auto value was set to 511.75 (or something very similar) but am unsure if i would want that number to increase or decrease in order to get temp drops. on top of this im not sure the dangerous of playing with the icc setting. any info would be much appreciated <3

If you are primarily using your pc for gaming, then you can do 2 things to lower temps, that will even make your pc run better in most cases.

Disable e-waste cores in bios, and disable turbo boost 3.0

That said, if you are reaching 100c in games, then there obviously is an issue - most likely a bad mount of the cpu cooler. Shouldn't reach more than 80c tops in gaming.

If I remember correctly, the maximum IccMax setting for the 13th and 14th Gen K and KF processors is 400 A.

Can you tell me how it is possible to have a CPU temperature of 100°C on a desktop?
 
Or get a better CPU cooler.

Did you undervolt both the core and the P cache? You need to undervolt both when using ThrottleStop. Post a screenshot of the FIVR window so I can see your settings.

You don't undervolt. Just drop the LLC to the 2nd to lowest or very lowest setting, and should run a lot cooler.

Nobody even asked about your board or cooling, but everybody here seems to know best.
Without more info from you, this is all guesswork at best.
I'd say keep reading from reputable sources, and don't run out and follow too much advice given here.
 
Please first post your specs. And like @P4-630 wrote, you might need both undervolting and a better cooler.
 
I actually had bigger gains undervolting the cache vs the core, although I have undervolts for both.

Same rules apply as overclocking, do as much testing as you can to gauge stability and remember its never an 100% assurance as ultimately you are running out of spec. There has also been a couple of reports (one from ir-cow and another from buildzoid) that undervolting can cause the CPU to slow down, however I think in both cases they were undervolting whilst also overclocking making it a more aggressive configuration, both using asus boards I think.

Easiest to test with with XTU as dont need reboots to make each adjustment.

One of the reasons CPU's might ship overvolted or bios's might pre configure overvolted that isnt related to binning margin is that adaptive voltage will overshoot when it moves up and down, so there is an additional margin to keep the CPU stable when it has downward overshoots. Motherboard quality according to buildzoid can impact this phenomenon with the better boards allowing a more aggressive undervolt. Fixed voltages can be a great way to overcome this issue at the expense of higher voltages when idle.
 
i do in fact need better cooling, i know this. I have a artic liquid freezer 2 sitting here but i am waiting on the correct mounting brackets to arrive as for some reason they dont ship with the lga1700 socket. The undervolt is not my only method of keeping this fucker cool lol but it is a meantime solution while i wait. i do appreciate all of your guys's help

It won't matter as much as you'd think.

The 14700K is vastly different that the 13600KF. Even a lot hotter then a 13700K.. all of these I've owned benchmarked and overclocked each.

Just lower the LLC as I had suggested and was ignored. Leave v-core at auto. It's a night and day difference.
 
Just lower the LLC
Good idea. Do you know what Loadline AC/DC values HWiNFO reports? My 10th Gen is quite happy with this set to 0.25. Ignoring the Intel recommended default values resulted in a big drop in temps. Very few people seem to talk about this important setting.

I know the feeling. :)

Still waiting to see a FIVR screenshot so I can see if there are any problems.

i am wondering if there is maybe a setting
I am wondering that too. A FIVR screenshot would answer a few questions. Some users have Undervolt Protection enabled in the BIOS. Undervolting will not work if that is the problem.

Cant say at this very time, but 0.500 mohm I believe.

Either way, good v-droop is OK. Under-volting works to a small extent.

The problem is Leakage. They are hot. leak more. That's why they are great for LN2 :)
