3950x Stock Idling Temps and Voltage

[sundawg89]

Hi all,

 

Recently upgraded from a 7700k to the Ryzen 3950x and have a Corsair H115i RGB PLATINUM 97 CFM Liquid CPU Cooler.

 

I am idling between 46-55C which seems high and the Voltage is idling at 1.4V which also seems high.

 

I have not overclocked at all and everything is at stock, other than memory profile which has DOCP enabled.

 

Is anyone else experiencing temps and voltages at this level?

1.4 for a 3950x isn't crazy

It's on the reasonable side

What temps do you get under load 

[sundawg89]

Never exceed 75 under heavy constant load. Usually stay at around 68-71C.

Thats good 

Idle temps Dont matter as long as temps under load are good

Ah thanks for that. I was more worried about the voltage as it seemed excessive so thought the motherboard might have set it to high by default.

The VID is what the cpu asks for 

If you want you can set a VDD which is what you supply

You can try 1.35 it should work but 1.4 for a 3950x is around what I would expect it to be at
