Hi everyone, new to the forum as i'm desperate for some help please.

I upgraded my Intel 8700k to a 14700k and the temp feels out of control hitting 100c often whilst gaming.

Undervolt options seem very limited, I tried a guide to offset voltage but that did F all.(I am by no means and expert)

Any suggestions for reducing temps is appreciated, i'm thinking maybe getting a newer case with a modular PSU might help a little or move to an AIO but the difference in temps between that and air seems negligible.



Specs:

14700K
Asus ROG Strix B760-F
Corsair Vengeane EXPO 32 gb 2x16GB
Deepcool AK620 Zero Dark CPU Cooler - 120mm
Case Corsair Carbide Air 740
Corsair non modular 950 watt psu

Things i've tried to reduce temps:
Lower voltage, using guide from Redit:
**This seems to have had a huge impact! Before the latest bios updates I tried the below and did nothing, tried again now and i'm not going past 89c playing D4**
"
  1. In Tweaker's Paradise there is an option for you to change to a previous microcode, and Microcode 104 is what you should select.
  2. After that you may start to undervolt in Ai Tweaker with the below steps:
- Leave "Actual VRM Core Voltage" on Auto

- Global Core SVID Voltage: set to Offset, choose negative (minus "-" icon), then start with 0.1

- Cache SVID Voltage: the same settings as Global Core SVID Voltage above

- You may increase to 0.125 or 0.15 if your stability test passed, mine is stable at 0.15

"

I had a similar problem although my temps didnt quite reach that high. Ive also got a b760 mobo which doesnt let you undervolt unless you change the microde. I read that this can cause serious stability problems so I avoided doing it.

What fixed the high temps for me was setting lower power limits. I set pl1 and pl2 both to 180w. This brought my temperatures right down with very little affect on perfomance.

Edit: Just noticed that you have an air cooler. I would say that you probably want to get an aio. Ive seen people struggling with temps even with 360 aio’s, myself included.

I'm cooling a 14700K with a Be Quiet! Dark Rock Pro 4 - the 620 is marginally better at cooling at lower fan RPMs but quite a bit noisier. I only hit 100C on the CPU in Cinebench R23 MT testing with the CPU cooler fan profile set to "silent" though with maxed fans it still gets into the 90s. In gaming it is usually around 70-80C.

(I can't remember which way around it is but mine is running PL1 at unlimited and PL2 at 280watt IIRC)

What thermal paste and application method are you using when mounting the heat sink? I highly recommend Arctic MX-6, using the line method, as some other pastes don't cope as well with full loaded temperatures on these 14th gen CPUs.

While AIO vs air cooler is relatively minor difference with lower heat output CPUs with these 14th gen the sheer amount of heat output will overwhelm an air cooler long before an AIO making for a bigger difference in temperatures during periods of high CPU activity.

Install Intel XTU. See if you can adjust the core voltage. If that is a no go you can drop the power limit levels to 120w very few games will go past that, if any.

There are a few things that you can do. On your motherboard do you have two EPS 12v connectors in the top left usually. Plug them both in if you haven't.

Are you using a contact frame? Since the 12900k there is an issue with manufacturers and their retention brackets which means it exerts too much pressure across the CPU causing it to bend. First off this creates a very bad contact with the heatspreader of the cooler. Secondly in some severe cases it makes bad contact with the memory pins of the CPU. I had a 12900k which would only boot with one stick of ram. I RMA'ed the motherboard bought about 2/3 sets of memory and still the same problem was about to RMA chip and thought I would the contact frame a go. Booted up first time with 4 sticks in. They only cost like a tenner.

Go into your bios screen and on all Asus motherboard they will have these two things you are looking for. Enforce motherboard Limit is on and disable multicore enhancement.

Try that and get back to us. If you are still unsure I can walk you through it. I have tons of Asus motherbaord with 12900k,13900k and 14900k and they all behave the same.

I have not heard of the Air cooler you are using. Generally speaking from the 13900k it a real struggle for air cooling doable like those big noctuas and other huge air cooling setups but I am not too familiar with the model you mentioned.
 
Before OP starts messing about with undervolting and power limits, etc. they need to make sure their cooling and airflow is working properly i.e. they've not forgotten to plug in the CPU fan(s), etc. except maybe with some Asus profiles they shouldn't be encountering 100C in things like gaming with a 14700K, aside from 1-2 very CPU heavy games maybe.

Thanks for the information, adjusted both PL1 and 2 to 180w and testing in Cinebench now, Scored 25k, temps are AMAZINGLY lower. Package maxing out so fat at 88c, P-Cores 91c and E-Cores 67c. So am thinking if this runs stable as I think it should I might look at upping the watts a bit more to see what performance/temps go up to.

I've have checked fans all airflow going from the front of the case through the CPU out the back with 2 fans extracting heat at the top as well. Not sure if this is the most optimised way of doing things. The games wouldn't run at a constant 100c but would spike to 100c but hover in the 90s which makes me itch.

Motherboard Default settings could be COOKING your CPU!

Seen this yesterday, was really annoyed, Jay uploaded a vid regarding Asus as well messing with those settings. This seems resolved now however after I updated the Bios again and now has a default setting called Intel optimised or something like that.

Thanks for the tip, I just blotted a pea size amount in the middle, I think I used Noctua paste or it couldve been Arctic however the tubes we're quite old so maybe if I used the line method with newly bought paste that might make a big difference. I am considering buying a new case with a AIO but the longevity of and AIO bothers me a little bit. My previous Notcua D15 I think it is lasting a lifetime.

You can't really go wrong with the blob method, maybe not always the most optimal but it is rare for it to cause a problem. Old paste could be a problem.

Hi man thanks for the response,

XTU doesn't work for me.

"There are a few things that you can do. On your motherboard do you have two EPS 12v connectors in the top left usually. Plug them both in if you haven't."

Holy **** I only have one plugged in! I dont think I had the other connecter on my PSU as it's like 10+ years old now. Might be a stupid question is this going to cause me issues?

Shouldn’t be an issue unless the CPU is pulling well over 300watts.

Pro tip, don’t buy Intel if thermals are important.

I would try using the latest Asus BIOS and XTU.

Asus have recently updated a lot of their BIOS' with the intel default settings, and in the process they seem to have fixed the issues that stopped XTU working with them. My motherboard is not the same as yours, but XTU now works with the latest BIOS. It didn't before that release.

Thanks, I mean there use to always be a lot of headroom for undervoling and overclocking. I guess a lot has changed since the 8 series.

You can, but some motherboards settings can be little more than random number generators and Intels microcode updates are pretty questionable.

Thanks again mate, I'm done with the offset and went with what you said adding in limits to power for Pl1 and 2, leaving it at 220w for now. Did a 30min stability test on cinebench and maxed out at 98c. Gaming it's not getting anywhere near that now. I was so close to buying a new case, new cooler and PSU or even moving to AMD in frustration.
 
They are quite hot running chips so a little fettling in BIOS is highly reccomended but it sounds like you are on the right path.

My understanding of two EPS 12v connectors V's one, is more to do with higher power delivery and more stability at higher loads on the hungrier chips. I don't think it would really affect temps, per-se.

As a rule I'd always use 2 where available, as I see it, it can only increase stability via a more stable power delivery to the CPU. Probably pointless on something like an i3, but for i7 or i9 I don't really see any downsides to using both.
