Question Intel 9700 CPU is overheating ?

Hi all!
So, recently I was given a PC. I don't know alot about it, just that buddy got a new one built, and he have me this one.

It was missing the cpu cooler.
It has 3 inlet and 1 outlet 120mm fans.

It's got an intel 9700 sitting in a MSI Z370-A pro.
I just installed a Thermaltake Assassin king 120se

I wiped the drives, reinstalled windows and updated the drivers. I then ran a cinnabench test and hit 90c inside the 1st min. 😵‍💫

So I checked the Fan curves and made sure 80c was running at 100%, that the OC genie or whatever is off and tried again. Same thing.


Pulled the cooler, paste looked good. Triple checked I removed the little plastic from the base, repasted, tried again.
Same result. 90c inside 1 min. 95c inside 3min.

Anyone have any ideas why this thing is trying to burn itself up? I'm at a loss here.
 
make sure the cooler is mounting correctly for this particular socket.
make sure the screws/fasteners aren't too tight or too loose.

have you verified that the cooler's fans are actually spinning?

i guess you've talked to the friend and they've stated that it was running fine before it came to you?

if you've not much experience putting together a system,
try to watch some videos for this particular socket
and for this particular cooler just to be sure you're doing everything correctly.

What case is this system using? If the case has restricted airflow, even though it has fans it could raise CPU temperatures. Also, what core voltage are you seeing it run at in Cinebench. What tool are you using to monitor the CPU temp?

Make sure to disable Intel MultiCore Enhancement in your BIOS. MSI may have it called "Enhanced Turbo" or "Intel Adaptive Boost". If you arent sure where to look I would reference the owners manual for your board, which you can find on MSIs website. This feature tends to increase heat, power consumption, and voltage greatly for what benefit it gives to frequency.

The Assassin King 120, while it is a good budget cooler, is on the small side for being able to cool an 8 core i7. I suspect this may be a lot of your problem, especially if MCE is enabled.

Thanks for the responses guys.

I'm monitoring temps with "coretemp"

I'm pretty sure the cooler is on correctly, everything seems to only fit one way, but I will watch some vids as maybe I have the mount screws too tight.

The case is probably a bit restrictive, it's pretty old, but I have the same problem panel on or off. I also don't have anything else making heat in there during these tests. It doesn't feel warm in the case, but the cooler sure does.

Core temp says:
Frequency is 4500.00mhz
ViD is 1.35V
Power is 170.1w
All the cores stay within a couple °C of each other.

I verified all the Fan speeds in the bios originally, and once it hits 80c the cpu fan is screaming pretty loudly.

I will try and get ahold of buddy, and see what was up with pc before. But I suspect he doesn't know much.
I'm not sure why it's missing the original cpu cooler, and suspect this might not be a new problem...

Small item but important. Did you check the AMOUNT of thermal paste you applied when installing this new cooler? (I assume you cleaned off all old paste before this.) Too MUCH paste is just as bad as too little - a thick paste film can slow down heat flow. So you need to add just the right amount for YOUR particular CPU chip. Check the paste makers' or the CPU maker's recommendations.

Windows settings > System > Power & Sleep > Related settings:Additional power settings > Control Panel-Power Options

Make sure it's on Balanced power plan, not Performance. "Performance" runs the CPU flat out at 100% and spins up fans as the first choice for cooling (instead of slowing down).

If you want to configure the details in the Balanced plan: Change plan settings > Change advanced power settings > Make sure Balanced is the active plan at the top drop-down > expand Processor power management settings (+)

I set mine to Minimum- 1%, system cooling policy to passive, and Maximum- 95%. This lets the CPU drop back, go down to idle, if the performance isn't needed.
If you explore the High Performance and Ultimate Performance plan settings, those are set to Min - 100%, active cooling, Max- 100%). Which means 100% at all times.

I used the least amount of paste that I thought would cover. I did clean the old stuff off.
I should have taken a picture when i took it back off. It covered the entire cpu, but only oozed over one edge slightly when I clamped the cooler down.
It's hard to tell from the videos for this cooler on my cpu, but the 2nd try I put about what the guy in the Thermaltake video did. (At least I tried too)

I will check windows power settings. I never knew about those.
As this is a fresh install of windows, on a new drive I expect it's just at the default settings but I sure will try what your recommended.

So, I have found a solution. I'm not sure it the right one, but it seems to be working.

I tried setting things up as @Task Force 141 suggested. And while temps did stay at a cool 41c with those settings, loosing base clock and boost clock sure was a bummer.

So, instead I went into the bios and found "lite load" it was set to Auto(17). After some testing I settled on setting 5.

Now I'm getting the same 4500mhz boost clock, but at 1.27v. That's lowered my power from 180w to 125w.

Now my temps are perfect.👌
2 back to back cinnabench runs resulted in 4 cores hitting 80c max, which brought the fans to full RPM, quickly sending the temps back down.

I tried a few different lite load modes, and obviously 1 was the coolest running, but blue screened on me and had a lower boost clock speed.
4 brought the clock speed up to the full 4500mhz, and gave no issues. So I went up one level to 5, just to make sure everything would be stable.

Thanks everyone for the help. Would love to hear if anyone has any wise words to why this won't work/could cause issue.
