Bad CPU Temps. with New AIO

[WillyG307]

I have recently purchased a new iCue Link H100i RGB from newegg and it doesn't seem to be doing a great job at cooling. I have reapplied thermal paste 3 times and made sure it is mounted tightly and properly and touching the CPU. I plugged it into the AIO_pump on the mother board (Asus ROG Strix B650-A gaming wifi) and made sure it's PWM and running at full. The temps are very bad on idle lowest going 49c and highest 70c and hovering around 55c just on windows. The temps fluctuate every couple of seconds and increase/decrease by 5-10c or even 20c. When running the iCue software it doesn't even go below 50c. I tried to play Fortnite and the temps fluctuated so badly it even spiked and peaked at 90c. It also is running very high temps even on bios such as 50c. I tried just watching Youtube and steam was in the background and it just stayed around 60c with nothing too demanding happening. Please help me!

Yo! Welcome to the Forum.

So you don't actually mention what CPU you have but since you are running a B650 I can asume its a Ryzen 7000 or 9000.

 

This is completely normal behaviour of Ryzen 7000/9000.  They dont work like any other CPU on the market in terms of temperatures.

They have a setpoint of 95c and they want to hit 95c before limiting clock speed or power.

They are DESIGNED to run at 95c 24/7.  Its weird, I know.. But thats the truth of it.

The CPU doesn't care if its at 50c or 93c, this is why you see so high temp while idle or light load.

My 7700x operates EXACTLY like yours. Its normal.

These CPU's bounce all over the place and its weird... But its normal   Dont worry.

It doesn't actually matter what cooler you have as mentioned in GamersNexus's video, it will still bounce around and display high temperatures.

 

Don't be alarmed by the fires in the thumbnails

Check the beginning of this video and skip to 24:16 for a recap in terms of temperatures how the new AM5 CPU's work.

 

 

Jay also goes through this in this own video and you can learn to see how the AM5 CPU's boost and behave.

 

 

You can follow this video to do some PBO tuning and curve optimizer for lower temperatures and slightly higher boost clocks.

Basically an overclock with an undervolt.

I did it with my 7700x, gained about 250Mhz and a few celcius lower temps.

Thank you so much for your help. You’re the first person to actually help me. I have the Ryzen 7 7800X3D, this whole time I thought it was the cooler I’m glad it wasn’t. Thank you so much for your help you’re a legend.

Hey!  No Problem

In the beginning when AM5 was quite new we got posts like these daily regarding temperatures and boosting behaviour regarding the Ryzen 7000.

People were so used to how Intel and AM4 was working that they were very confused and scared when they saw high temperatures with the Ryzen 7000.

Its nothing to be scared or worried about however.

 

Since you are running an ASUS motherboard I will highly recommend updating the BIOS if you haven't done so already.

ASUS ( And other motherboard manufacturers ) had some issues with 7000 X3D's burning on older BIOS due to higher voltage and was fixed in a BIOS update.

Please update your BIOS if you haven't done so already!!!

 

This can also lower your temperatures slightly

It should actually limit the X3D CPU to 85c as TJMAX instead of 95C as on non X3D CPU's.

 

 

But as you saw in basically all 3 videos I linked, Ryzen 7000/9000 just run hot by design.
