PC Processors

Hello everybody,

Yesterday, I finished my new build featuring the Ryzen 7 3700x, it contains:

Ryzen 7 3700X

MSI X470 Gaming Pro Carbon

Be Quiet! Dark Rock 4

16 GB DDR4 Tridenz Z RGB 3200 Mhz CL16

Fresh Copy of Windows 10

Fractal Design Meshify C with 2 intakes 1 exhaust

Now, after some testing around and monitoring the statistics I found the following:

When enabling PBO in the Bios, the voltage likes to spike up to 1.5V, so I set an offset of -.1v, now it does not exceed 1.4v.

Furthermore, I have enabled auto-oc, but I have not adjusted any settings, just set everything to "enabled".

When doing a stresstest, Aida64 for example, all cores go up to around 4.1, 4.2 Ghz with just under 1.4 Volts.

My main problem now are the temperatures.

When stresstesting, it goes well above 70 C, sometimes it spikes even in the 80s.

From all the reviews that I have read, noone had such high temps.

I have not adjusted any settings in Ryzen Master because I have not had the time to learn the software.

If there are any tweaks that I could do to improve things, I will do my best to try them!

Reseating the cooler will be the first thing that I will do, but I doubt that this will change anything at all...

Thank you for your help!

The Ryzen 7 3700x (and other Ryzen 5 series I worked with before) has very high internal thermal resistence. It is about 0.4 C/W for this model. The exact number should be provided by the manufacturer. So even if you have "infinite" cooling capacity capable of keepening the IHS at ambient temperature and you have 20C ambient temperature then with 90W dissipation you will have about 20C + 0.4C/W * 90W = 56C die temperature. I have an EK Velocity waterblock in a custom water cooling loop with a 280 and a 420 radiators cooling the CPU only and with 25C ambient using Prime 95 I get about 65C Tdie in HWiNFO64 for my 3700x. This is well within the temperature specs limit but it is funny that I could keep my 125W TDP FX-8120 processor at a lower Tdie with simple air cooling. Probably the issue is with the TIM applied between the die and the IHS on this model so probably using delidding you could get lower Tdie but as the specs specifies way higher Tmax there is no point in doing that.
