Insanely high IDLE CPU temps (Ryzen 5 3600)

[TwoShoes]

yo. I just upgraded my CPU from a Ryzen 3 2600g to a Ryzen 5 3600. My motherboard is the ASROCK b450m pro4. (the rest of my PC specs can be found in the pcpartpicker list below) The PC is fully functional and all the parts seem to be working as expected (case fans, cpu fans spinning). However, my CPU is reaching crazy idle temperatures - I recorded temperatures of 90+ (Celsius) when idle (1% usage). When running games, I reached over 100 degrees C. A simple google search told me the stock cooler comes with thermal paste, which I can only assume is the grey layer of sludge that obscured the Ryzen logo on the CPU itself. Before upgrading my CPU, I had to update my bios for the mother to recognise it. In accordance with the ASROCK website, I upgraded to BIOS version 3.3, which is what the final column says (shown below).

 

Does anyone have any ideas about why my computer is so hot? Any advice would be greatly appreciated. Thank you in advance.

Yes, the grey sludge you found on your old 2200G (There is no 2600G) was the thermal paste. When you put in the new CPU, you should've cleaned the cooler and CPU,

applied new thermal paste and then put on the new cooler. Running 100+ degrees will damage the CPU so until you can replace the thermal paste and make sure the contact between CPU and cooler is sufficient, don't use the computer.

How are you measuring the temps?

CoreTemp is a program that I have found to be highly accurate.

I installed a new fan with the new CPU - I purchased a new CPU and new stock cooler - does the stock cooler not apply the thermal paste to the new CPU? Sorry if I wasn't clear earlier.

CoreTemp is what I was using - I got idle temps of around 95+ on all cores.

If the cooler still had the grey thermal paste squares on the bottom, yes, it came with it. If the temps are still very high after that, the mounting pressure might be insufficient.

Cross check with other software, like HWMonitor and HWinfo64 to make sure.

Will do. I checked my CPU temps in my BIOS too and received similar temperatures so I don't think there's a miscalculation error.

[Guest]

Even a cooler with no thermal paste at all should give lower temps than that. I would agree with other people and say that the measurement itself could be wrong.

Try installing Ryzen Master and see what temp it says.

 

Edit: Just saw your reply saying you checked in BIOS too. It might still also be useful to see how much power the CPU is drawing. The high temp could just be a synmptom of a different problem like a power issue. Ryzen Master can show you the power draw.

Definitely not. Without thermal paste, surface area that needs to cool down a 65W heat source is smaller than your thumb. Either OP has no thermal paste or did not mount the cooler.

Sounds like a bad mount. Try remounting the CPU cooler, and also removing the thermal paste that's on there and applying some fresh one, if you've got any on hand.

 

Also, try being extra careful when you're taking the cooler off. Because of the AM4 socket and CPUs, often times the especially sticky thermal paste will glue the CPU to the cooler and pull it right out of the socket (which isn't ideal, to say the least).

A good idea would be removing the cooler right after shutting down the system (so the paste is still warm), and also pull the cooler off with a twisting motion, as opposed to just pulling it straight up.

at Idle a metal to metal contact between heat spreader and cooler plate with no paste would not run anywhere near 90c. That has been proven many times. At full load yes it would likely hit that.

Hi again. I have just installed Ryzen Master, the temps read from around 50-80 degrees C when not running any games. In terms of difference between Core Temp and Ryzen Master, there is around a 10 degrees difference. I have attached a screenshot of Ryzen Master - it doesn't mean anything to me but maybe to you. If you have any advice on what power settings to tweak, if there is a problem with the 'power draw' and not hardware, I would be very appreciative. Should I decrease the amount of power going to the CPU?

 

Thanks.

This is at idle?

I mean I had google chrome, ryzen master and maybe one other program running. The cpu was hardly utilized (2% usage maybe)

The PPT is about double what it should be. Should be around 30% at idle yours is 60%. The TDC and EDC all look too high as well. Probably double what they should be at idle.
Whatever is causing the high power usage is why you have high temps.

You might find someone will come along and know exactly what's happening which would be great but I would need to do a bit of research.

I am running the 3600X and exact same motherboard. Let me check a few things and I'll get back to you

Ok thank you. The rest of my components are linked on the original post. I have tweaked a couple things recently regarding power usage (changing power plans etc) but they didn't affect my old CPU and I doubt they would do any harm.

Could be related. What power plan are you using?

Did you change any CPU voltages in BIOS?

I am using AMD's custom power plan, this was one of the first things I tried to lower CPU temps. I haven't changed anything in the BIOS apart from fan speeds, but they come on at around 40% anyway (which is currently the whole time) so I don't thing that would affect anything.

[TwoShoes]

yo

 

I already posted this in another thread but I have seemingly narrowed down the problem. I upgraded my CPU from a Ryzen 3 2200g to a Ryzen 5 3600. Since the install, I have been hitting insane idle temperatures of 80-100 degrees. I have thermal paste on the CPU and I'm fairly confident the fan is installed properly - all the case fans are also working. I was advised to install Ryzen Master to analyse the issue. I have attached a screenshot below of my idle CPU. I have already been told my 'PPT' is around double what it should be, and the TDC and EDC are also too high. Does anyone have any ideas - is this a power related issue?

 

Thank you in advance.

Do me a favor. In Ryzen Master click on Game Mode. At the bottom of that screen click Apply.
Then go back to Home and see if those temp and power figures change at all

[TwoShoes]

The power figures seem to have improved. The temp is still around 50 degrees, which seems a little high. This definitely made a difference. I don't know what will happen when I try to stream/play though.

Yes, that's a start although there are still a few things I'd want to do if I was you. 50 is still a little high for stock cooler. How is the airflow in your case?

8.174W CPU power is too high for idle. DOes it drop lower and occasionally go up to around 8 or is it pegged at around 8? Edit - actually ignore that question. 8 would be fine if you were doing something, in fact higher would be fine if you were doing stuff.
Which windows power plan are you running? I would reccomend you go to "Ryzen Balanced" for now. It should be available as a power plan if you have the latest chipset drivers installed.

Your memory settings look a little off, we can hopefully sort that out too.

I have 3 case fans and one cpu fan, I never used to have problems with cooling. With my old CPU, the temps would never rise high enough for the fans to even be audible.

I switched my power plan

Also, how do I make the Ryzen Master settings save? When I close the program the temps rise a bit and upon opening it again, the 'game' plan is no longer selected.

Thank you again for all your help and swift responses!
