high temps after bios update / ASUS TUF GAMING Z790-PLUS WIFI

[Matthew5]

Hello, i got new Computer this year that had problems with temps from the start, i lowered temps by doing -0.065 global core SVID voltage, it helped alot, max temp in cinebench was from 100c to 78c(in summer), bios 1656.

Now after updating the bios to the latest 1805, I have temperatures in cinebench close to 98c(in winter, so in summer it will be 100c for sure) and I can't lower them anymore with globalcore SVID anymore, tried VRM core voltage and got same results.
Fans are running weirdly like for no reason while gaming it start to go MAX Speed and then back to normal and this repeats with some pause in between. Before the update the fans were more stable..

I was thinking of trying to downgrade the bios, but I'm scared and confused about the microcode update, I don't want the new processor to get corrupted.
What should i do ? Can anybody help me please what should i do to lower temps ? Or with good temps, is it safe to be on older bios version without microcode ?

No BSODS to this moment and only bios tweak are XMP1 and -0.065 global core SVID

Hello @Matthew5 

Thank you for reaching out to us.
If you notice that the CPU voltage and temperature are high, this is due to the power and performance settings preset by the BIOS, particularly during high-performance workloads such as running Cinebench or playing games. Temperatures around 90 degrees Celsius are still within the safe range for the CPU. 

May I ask if the CPU temperature differs in Cinebench results after clearing CMOS, with no XMP settings or other manual adjustments enabled? Please note that Cinebench may record short-term temperature peaks.
Additionally, ASUS follows Intel’s recommendations to set voltage and other temperature protection mechanisms to provide more immediate protection for the CPU. If you needs better performance, it is recommended to upgrade to a better cooling system. 
The following measures can be taken to further reduce the CPU temperature:
1. Ensure that the CPU cooler is securely installed and check that the thermal paste effectively covers the CPU surface.
2. Increase the airflow within the chassis to ensure good air circulation, especially under high loads.

Thank you.

That was a most unhelpful answer to the persons question and concern. 
updating the bios shouldn’t have caused their cpu to jump 20c and saying it’s normal or even with safe range doesn’t change the fact that in this day and age of computer gaming anything over 75c at most is a cause for concern.  

maybe just maybe asus screwed up with the latest bios update and it deserves a check out because plenty of people have said this exact same thing and have the exact same problem with the latest bios. 

Even I’m experiencing weird fan issues that I didn’t have before this update and my cpu went from running while gaming 28-32c up to 37-44c running NOTHING.  Considering I’ve got it paired with an AIO with plenty of ventilation and decided to do the update at the end of the day after I was done gaming shows it’s not a problem with OPs rig/fans it’s a problem with ASUS and the latest update. 

So maybe just maybe you should come back with a few better answers.

Actually, @Jiaszzz_ROG is correct. Because she understands what the BIOS update entails. 

1. The update results in following Intel's recommendations for ACLL, this will result in higher temperatures than what one might be accustomed to on older BIOS. This is because motherboard vendors (ASUS included), undervolved the CPU by manipulating the loadline. On more recent BIOS, which also include newer CPU ucode, the default preference does not deviate from Intel specification. This can result in marginally more voltage under load.

2. You can still fully manipulate such things manually. The easiest method is to change the SVID Behaviour setting. 

Not that I needed a reason to say this, but watch your attitude. The fact that you were off-base with that post only adds to make it worse.

[Cubia]

@Silent_Scone I’m not saying they weren’t correct I’m saying it wasn’t helpful for this persons dilemma.  They already said they manipulated the svid and still had high temps.  I deal with electronics and technology on a daily basis and trust me fully understand what’s going on and even said Asus has the cpu running up to maximum at all times with turbo boost enabled instead of gradual rises until tasks are completed like most other boards.  

what I told OP to do was literally an actual way to bring down their temps with a rig that is already fully capable of having low temps.  Whereas @Jiaszzz_ROG tried pushing the blame back on OP saying they need better cooling.  Which isn’t and wasn’t helpful.  They fully described their computer setup and they have amazing cooling quality as it stands.  The problem is with the Asus boards and the devs behind the updates for the way your boards are working and if you cant see that then you’re part of the problem.  Plenty of threads of people having the exact same issues for all of says boards a lot more than similar boards in the same category by different manufacturers.  

Ill reiterate I’m not attacking anyone I’m simply stating a fact there is a flaw with how your boards are acting and I have given OP a great way to lower their temps and didn’t off the cuff doubt their knowledge or expertise with how to manage their PC. I read their specs understood their problem and gave them a logical response vs a copy paste and “hey update your cooling” showing they didn’t even read what OP had. 

[Silent_Scone]

Still seems like you don’t follow. The loadline behaviour now follows Intel spec, that’s all that really needs to be said. There’s no need for cryptic accusations about ASUS doing something wrong.

One is free to still adjust settings such as loadline or offset to help with load temps. I’m not sure there’s really anything else that needs to be said. The fact is, ASUS previously undervolted the CPU out of the box. Thats no longer the case. 

No need to disable Turbo and hamper performance, adjusting SVID Behaviour (not the same as global offset) should be sufficient to reduce load temperature.

The post you were replying to touches on these changes whilst also asking for more detailed information to ensure there isn’t anything abnormal. The reactive post wasn’t needed, as nothing in the post was unhelpful. I’d implore more tuning suggestions, but keep things grounded. 👍

[Cubia]

@Silent_Scone No one was being cryptic I was simply stating a fact that I did do testing with several boards and ASUS was the only one that had this load issue after a bios update.  You are right that you are using intels settings but checking it again default actually sets quite a few settings to ASUS recommended settings within the AI tweaker.  

You are right people can adjust quite extensively in the MB settings. Though for a normal run of the mill person who may come across this board and may not want to risk killing their rig and are looking for a fast way to reduce fan noise and temps this may not be an option now is it? 

Disabling turbo boost doesn’t hamper any performance and is the fastest way to reduce cpu load temps simple as that.  Cinebench yes will give you a lower score but who cares honestly for a normal person?  Like I said even with turbo boost disabled a person will still run cpu intensive games and see no drawbacks and if you give me a single game that you’ll see a drawback on I’ll happily retract that statement.  A drawback meaning it “hampers” the gameplay performance.  

[Silent_Scone]

Again, best to ask questions rather than pose them as vague statements to avoid going around in circles.

You'd be partially right that some settings favour "ASUS recommendations" but these are by design

Take IA TDC Current Limit, for example. Most users probably don't know what this does. By default, it is set to Motherboard Capability. This is intentional.

Furthermore, if one only intends to run games why be concerned with voltage / current usage at all? Within spec and at default, the CPU won't even reach stock TDP. So no need to retract statements, and more reason to focus on the facts. For instance, you could have just suggested the user adjust SVID Behaviour setting to Typical. 

[Cubia]

@Silent_Scone 

Have you yourself changed the svid to typical or did you find the Reddit thread where people who were having the same issues and decided to suggest it.  Because trust me changing it to typical doesn’t change the voltage usage unless you change it to a negative factor and then also change the increments you want to lower it.  Which is still not something most run of the mill populace would want to risk messing with.  Also not to sound crass but most people tweaking voltages and current usage are literally gamers trying to push their rigs because that’s what YouTubers say you need to do.  You saying no need to adjust that it won’t even reach TDP whilst gaming is simply put wrong.  Go to any z790 asus motherboard load up the latest bios y’all have released and set to default and let me know how high your fans get along with your cpu temps because I assure you they will be going way above what’s necessary for gaming for absolutely no reason.  

I’m not doubting you know what you are talking about but again it’s not helpful for the greater majority of your users.  

[Silent_Scone]

1.Changing the SVID behaviour directly alters the ACLL.The fact you're still referring to a "negative factor" shows you're still conflating or confused as to what this setting does.

2. Not sure what fans have to do with anything as the variance between fan types is significant. The curve gradient is based on T-Case. Doesn't have any direct correlation to the temperatures the OP is seeing.  You're just leading yourself and others up the garden path with that one. Yes, his fans will be loud - his temps are higher.

Best to let support intervene. 👍
You're entitled to start your own thread if you still believe there's some kind of issue.
