Which one is more reliable ? Ryzen 9 3900x with stock cooler Core temp is saying mid 50s to 60s at idle Ryzen master is saying low 50s to mid 50s idle .

Thanks!

Hi,

I've a 3900X on a MSI B450I motherboard. Yesterday night I had my fans ramping up and down constantly. I use CAM (little dissapointed by this software but that's another subjet) and had ryzen master and hwinfo open. After a couple minutes of observation I can tell that ryzen master show a temperature in a 5-20° range LOWER than CAM or hwinfo.

CAM and hwinfo are within the same 0-5° range that can be explained by the time the sensor got probed however this cannot be an explanation for ryzen master. It sits for long period of time like 10° lower than any other tool.

So what are you guys seeing ? Is this an MSI bios offset issue or did AMD tweaked their temperature sensor in ryzen master so that it shows lower temps ?

CAM 3.7.8

Ryzen master 2.0.1.1233

HWInfo 6.10

Edit : Info in AMD PDF :

For temperatures:

• OLD BEHAVIOR: Report the highest temp (“instantaneous temperature”) of any sensor in the whole CPU, no matter how isolated or brief. This approach overstated the prevalence and significance of fleeting peaks, which artificially inflated temperature reports by up to 30°C above the true silicon conditions.

• NEW BEHAVIOR: Report a short-duration rolling average of all temp sensors in the chip. This model will give you a holistic view of what the processor is doing across cores, cache, bus interfaces, etc. It’s the closest any software monitoring tool can come to portraying the true thermal conditions of the chip, and it’s the same model our own Precision Boost 2 algorithm uses to make temperature-related boost decisions.

ADDITIONALLY: We also intend to release new developer documentation that enables third-party tools to take the same measurements, so you can continue to rely on your favorite third-party apps after they’re updated. We will be contacting utility vendors directly with more details when the documentation is ready.

Edit : to be clear, exposing a problem and being picky about it does not mean I shit on AMD. The CPU is great and a huge upgrade from my previous one. I just feel they need a new team (or add new ressources if it does already exists) that work on integration at all levels (bios, software, behavior etc) so that we don't get a shitstorm at every launch. We often talk about brand image, those launch pretty much hurt it.

I'm noticing Ryzen Master sometimes showing my 5800x running up to 10 degrees cooler. I was a bit worried about the readings in HWMonitor, but if Ryzen Master is telling the truth, my thermals aren't so bad after all.

My NZXT Z73 CPU temperature says 50 degrees and the AMD Ryzen Master says 40, just wondering which is accurate.

I use Ryzen Master and MSI Afterburner to monitor temps, but they give me different temps. MSI Afterburner has my CPU temps bounce up and down, but Ryzen Master gives a more stable temperature.

Is MSI Afterburner better to use for GPU temps and Ryzen Master better for CPU temps?

On idle ryzen master shows about 45 degrees and core temps from 50-60. At load they both show around 80.

I take it ryzen master is more accurate?

I have been trying to figure out the temps on my 3700x but that seems to be quite the task since every software I try gives different readings. I have tried Ryzen Master, HWInfo and HW Monitor. Before I try Speccy I thought I'd ask what software is the most accurate an reading temps.

The problem is that Ryzen Master report idle temps at 35-37, HWINfor says its 30-33 and HWMonitor says its 39-41. It gets even crazier under load. In Battlefield V RM says max temp at around 70-73, HWInfo ended on 65 and HWMonitor went all the way up to 80.

I'd like to think RM is the most accurate considering it comes from AMD but I dont like the software since I cant seem to get a log saying what max temp is and when alt tabbing the temp do change a few degrees so I have no chance to get the correct max temp. On the two others it says Max temp so I do not need to alt tab all the time trying to find where the cpu ends up. I have kind of ruled out HWMonitor since the case fans doesnt go up to 100% when HWMonitor report 80 degrees.

So anyone have any idea which software really is the most accurate?

And are there any way to get a log out of RM?

I use a 3600xt and was wandering why my CPU is always running ar 4400MHz ( Afterburner, HDinfo, DragonCenter) so I installed Ryzen master, where the CPU runs at about 1500MHz and the Idle Temperature is different, while Ryzeb Master says its Idle temp is between 37 and 50c, Afterburner, HWinfo and Dragon Center show the temp between 50 and high 60c. Which us the correct answer and which is my CPU cooler using (Mugen 5 black Edition)?

Ryzen master consistently reports temps around 10 c lower than hwmonitor. highest temp reported by ryzen master that i've seen is 81, while hwmonitor consistently reports maxes of 90 - all safe temps (safe operating temp is 95) and i havent had any functional issues but i'd like to know whats going on. Are the two apps reading from different sensors? My system has never thermal throttled.

edit: i did some digging and it looks like early ryzens had a 20c offset applied to them in ryzen master which would explain differences there, but mine is a 3600 and the offset is nowhere near 20. also the offset was quickly accounted for in updates for 3rd party monitoring apps
