Cool Case Temp but High CPU Temp

[SirMatter]

Hi All,

 

This is my first build and first post... so very new to all this. Please forgive my ignorance!

 

I have noticed my case temps measured on my MOBO are idling at 23-25c and maxing at 35c. CPU is reaching mid 70s when gaming and mid 90s when running Cinebench R20. Is this normal? Seems really high from all that I have seen.

 

CPU: Ryzen 3600 with Stock fan

MOBO: Gigabyte x570 UD

GPU: RX 5600XT

Case: Phanteks Eclipse 350x

2 Extra static pressure case fans I had.

 

I have already updated chipset drivers, all other drivers, and windows shows no updates needed. I have not updated BIOS yet (a little nervous).

For the stock cooler, those are normal temps.

 

I'm running a Dark Rock 4, and my temps reach about 70C at full load, with up to 81C if the GPU is on full load.

 

It's probably not worth worrying about. Your temps are still safe.

Make sure your cooler is well mounted and that your BIOS isn't overvolting the CPU. Gigabyte has notoriously shitty BIOSes with regard to voltage

Thank you for the response!

 

Is there anything I should do with my stock fan curve to help lower the temps? I am nervous being a first time builder that I am going to shorten the life of my CPU.

How do I know if it is overvolting? Obviously in BIOS but is there a specific max voltage I should set?

No, I'd say use Ryzen Master to check what cinebench voltage you get across all cores

Ok. I already downloaded Ryzen Master. 

 

I believe the max voltage of Ryzen 3600 is 1.5v (I think I read that somewhere). Do I just make sure it doesn't pass that?

1.5 all core is absurd. All core it should be 1.37 and that's with PBO enabled

Great! Thank you for all the help!

Just as a followup. I ran R20 and did not pass 1.38v. Temp maxed at 90c according to Ryzen Master. Seems like the stock fan can maintain a temp below 95c. Very high compared what I am used to but I will continue to monitor it.

You could downvolt it. Or turn of PBO (pretty much equal to MCE on Intel, and very close to auto-OC in effectivity on clocks and voltages).

I wanted to do a quick follow up if anyone comes across this thread. I learned that stock Ryzen receives more Voltage than it needs. I was able to undervolt the cpu to 1.15v while maintaining a 4.15gz on all cores which brings the max temps down significantly. 

prior to undervolt I was getting a r20 score of 3550 with max temps of 98.8c

 

with a 1.15v undervolt and a 4.15gz on all cores, I am getting about 3770 in r20.L with max temps of 88.8c. 
 

I haven’t noticed a single core performance drop either. 

 

to sum up: I am getting better Performance with lower voltage. Pretty amazing!
