Ryzen 5 3600, what should be the normal idle temp with stock cooler?

I just built a new system, this is my first ryzen build, specs:

uP: Ryzen 5 3600

Motherboard: B450 Aorus Pro Wifi. 

RAM: Corsiar Vengeance DDR4 16GB 3200MHz.

VGA: Asus ROG Strix GTX 1660 super advanced edition.

SSD: Samsung 970 Evo plus 250GB.

PSU: Seasonic GX-550.

Windows 10 Pro 64 bits.

 

I'm using the stock cooler that came with the 3600, and i was surprised to see the idle temperature is 50° to 55°C with the CPU at 2% or 3% of usage according to the task manager and with a very cold room temperature (around 20°C).

I have never seen any CPU with more than 40 or 45°C at idle, and I think this temp is so high for the 3600 even using the stock cooler, I have seen in some reviews and comments the idle temp should be around 35°C with stock cooler. If I run any stress software the temperature goes beyond 80°C in just a few seconds...

I have tried many solutions suggested in many sites, like disabling PBO, XFR in BIOS, changing the power plan, updating all drivers and latest BIOS... etc, but nothing changes, at most the variant is around 1 or 2°C below, so:

What should be the "normal" temp at idle for this processor with stock cooler?

Why the idle temp is so high?

I got a defective processor?

I know you will say:"just get a better cooler" but for the first tests without changing the cooler I think this temperatures are not normal, I don't like AIOs, and air coolers, like cooler master hyper 212 are very expensive here ($50 USD or more).

It seems those temps will make impossible to use this processor with the stock cooler, and that is very disappointing, and the worst part is: if I get a better cooler, I don't know how much this could help, that's why I want to know if there is something bad with this processor before spend more money on it...

Re: Ryzen 5 3600, what should be the normal idle temp with stock cooler?

I have a 3600x and sit around 38C at idle with around 20C ambient.

The cooler with the 3600 isn't very good but I would still expect it to around 40C at idle.

I would check the mounting your possibly not getting a very even contact with the cpu.

It might also be an issue with case airflow, how many fans do you have blowing into and out of the case. Trying running without the side panel on would probably show if this is the issue.

You might be able to grab a cheap wraith prism off ebay if you want a better cooler. Most people that buy the bigger chips use better cooling and sell them off pretty cheap.

Re: Ryzen 5 3600, what should be the normal idle temp with stock cooler?

Forgot to mention that details:

The case is a Corsair "iCUE 220T RGB Airflow", it has 3 fans at the front, the airflow is enough to have "good" temperatures, and I'm making all tests without the side panel, it does not matter if the cover is in place or not, same results. Even running all 3 frontal fans at high speeds don't change nothing.

I have checked twice the mounting of the cooler, all is good placed (I'm wasting too much thermal compound).

I'm starting thinking something is defective, but now I don't know which part.

Could be a Motherboard issue?

Defective 3600, or only a very bad quality one?

I have seen searching, more people is having this issue with high temps, but I can not find any good solution, I'm start thinking there are too many processors with very low quality giving too high temps...

Re: Ryzen 5 3600, what should be the normal idle temp with stock cooler?

The Ryzen 5 3600 has a TDP of 65 watts while the AMD Wraith Stealth has a TDP of 65 Watts.

The AMD Stealth is the CPU Cooler that comes bundled with the 3600 processor.

The Wraith Stealth is the weakest of all the newest Wraith CPU Coolers but it is adequate for normal computing though it will run hotter than a more powerful 3rd party CPU Cooler like the Hyper212 EVO which has a TDP of 150 Watts or Wraith Prism.

This previous Tech site gives a very good comparison and review of the three Wraith CPU Coolers, Stealth, Spire, & Prism: https://www.techspot.com/review/1635-amd-wraith-coolers-compared/

Note: The tech site uses a Ryzen 2600 processor which has the same TDP as the 3600 processor. Here is its conclusion to its test concerning the Wraith Stealth:

Conclusion

We hope that those of you building a new Ryzen system that have been wanting to see how the Stealth, Spire and Prism compare are satisfied with this testing. If you have a Ryzen 5 2600 or any other AMD CPU that comes bundled with the Wraith Stealth you’ll ideally want to upgrade the cooler for better thermal performance, especially if you plan on overclocking.

It seems like a lot of you want to stick with an AMD branded cooler and while I agree they look nice, it’s not really a cost effective option. Looking at places such as Ebay it seems like most Wraith Prism coolers are selling for around $40 + shipping, for that kind of money you can get a seriously good air cooler.

Couldn't agree more! But if you have decent contact with decent thermal paste, try running the fan curve up a bit. The cooler that comes with the 3600X is better. I used it briefly while waiting for an AM4 bracket for my AIO, my idle was around 40c. Gaming it would go up to 60-80c and hold. Still far from shutdown or damage.

FYI, it will clock down and actually shutdown if it hits the TjMax of 90c. 95c, shutdown. I know because I accidently knocked the plug off my pump and the PC would shutdown in seconds. No damage done. So the built-in safety measure works. I think you're ok with the stock cooler.

Even running the Corsair H110i GTX in a 21c room I'm idle at 42c on the die with 20c at the AIO. In game the die temp is 65-70c. Prime95 steady 80c. So no worries, these 3600's fluctuate a lot in temp, frequency and voltage. As long as the temp isn't creeping up to no end, or not coming back down fairly quick after running a game or something, it's fine.

Re: Ryzen 5 3600, what should be the normal idle temp with stock cooler?

I'm still confused...

In the link you provide with the test of the coolers: R5 2600, wraith stealth: Idle temp 33°C

Here a review of the R5 3600: https://www.techspot.com/review/1871-amd-ryzen-3600/

wraith stealth: Idle temp 33°C

One more review R5 3600 (in french): https://overclocking.com/test-ryzen-5-3600/17/

wraith stealth: Idle temp 35°C

MINE: wraith stealth: Idle temp 50°C ???????

Is AMD sending good samples to reviewers and then selling very low quality processors to consumers?

Re: Ryzen 5 3600, what should be the normal idle temp with stock cooler?

You can't rely on some reviews in regards to idle temps/load temps because your case is probably a different one, room temp is most likely not "controlled". Board voltage can vary. BIOS temp sensors can be off. Many variables. If you're idling at 50c, something either isn't getting proper airflow, like your case doesn't have a side intake option. Perhaps the cooler isn't seated correctly or has too much thermal compound on it. You have the "zero RPM" option enabled in BIOS (Cool n Quiet), something like that. Certain BIOS settings like PBO, Scalar set to 10X, Vcore too high manually, setting SOC over 1;.10v, all core OC can cause this.

Rare and seen only once, the cooler wasn't machined flat and was actually not contacting 1/3 of the die lid. Check that by laying the cooler upside down and use a metal straight edge and piece of paper, preferably a real thickness gauge to check for gaps greater than .001" diagonally across the mating surface.

You're second link refers to a liquid cooled system. I translated it from French. In any case, check out what I said above. Airflow, case design, fan locations, BIOS settings like "cool n quiet" or "zero RPM" (disable those), possibility of the cooler not seating properly for the reasons above, too much thermal paste, no thermal paste, CPU fan defective (cannot turn freely by hand, broken/missing blades). Make sure the CPU fan is plugged into the correct fan header marked "CPU Fan" with 4 pins. 3 pin headers are typically chassis connectors and are not PWM, so don't use a 3 pin connector for that fan.

The CPU is not defective for running hot. whatever is on the CPU is responsible for cooling it. Aside form BIOS fan settings or voltages set too high for Vcore, something else is going on. If this temp you see is only in BIOS's hardware info page, disregard it and check within the OS. BIOS runs the CPU at full load and is not an accurate "real world" example of your CPU's working temp. 

Applying thermal paste tip: Either a thin coating or a dime sized/large pea, blob dead center of the CPU die is fine. Then reattach the cooler. 

Based on your case brand a 3rd party cooler might be an option like: COOLER MASTER Hyper 212 EVO 120mm Sleeve CPU Cooler - Newegg.com or a flatter design. Here's a review of your case and note the style CPU cooler used: Corsair 220T Airflow Case Review: Testing the Marketing - YouTube 

Your case has front to rear airflow and the CPU is miles away from those front intake fans. I've had Corsair cases and they all seem to follow that design pattern of no side fan and it has caused cooling issues for me with stock air coolers.

Should the stock cooler be defective and you want to have AMD replace it, you'll need to RMA the entire package back to them. If you still have a return window from the vendor, do that as it's much faster. Personally, I'd just get a cooler and be done if none of the above other issues are a factor and it boils down to the cooler itself. Any 3rd party cooler in general is better than the stock one.

Re: Ryzen 5 3600, what should be the normal idle temp with stock cooler?

sorry for the delay, so busy last days, I can not start using this PC due the the temperature issues...

- In the french review they said they used the stock cooler after the AIO tests ("Et le Radstock ?" section) with 35° C at idle.

- Even with "controlled conditions" the difference should not be more than 5°, maybe 10° as much. mine is above 15°, see this I found:

https://linustechtips.com/topic/1118077-getting-very-high-idle-temperatures-55-65-on-ryzen-5-3600-st...

Read the first comment of: Mark Kaine, R 5 3600, bad airflow case, all fans stopped in idle, stock cooler: 32 to 35°C. An the CPU is reaching easily 4.2GHZ boost.

My processor even is not reaching the 4.2GHz at boost, only 3.9GHz.

- All my voltages are normal, even Ryzen master reports an average CPU voltage of around 0.5V on idle, and speeds of 400MHz with most of the cores in sleep mode, so no voltage problem, even with a single core active the idle temp is so high.

- If I try to run Prime 95 after 6 minutes the temperature goes above 100°C (of course I don't know how much beyond because I sopped the test immediately...)

- The stock cooler is not defective, the surface is perfectly flat, the fan is working good, I'm using Arctic MX-4, good thermal paste. The cooler is placed correctly, no mechanical problems.

- The case is not the problem, is has good airflow, probably this is the best airflow case I have ever used, I placed a 120mm fan at rear to improve airflow, NO change. Open side panel: NO change.

- I have tested every single combination on BIOS: PBO, XFR, Cool and quiet, disable XMP profile...................

even if I disable cool and quiet the temperature rises 2 or 3 degrees more.

Inside the BIOS the temperature reading is 45°C, lower than windows...

Every time I'm more convinced I got and extremely bad quality CPU.

- I have got an old Cooler master Hyper TX3 used in an old PC but is in perfect conditions, I'm making some tests with it, but it seems the results are not much better, I will update it soon...

Re: Ryzen 5 3600, what should be the normal idle temp with stock cooler?

The problem you are having can be a tough one to solve without being there, sadly. I've just built a Ryzen 3600 with (1st) the stock cooler, then replaced with a Corsair H60 AOI after a couple days. Monitoring temps whilst benchmarking using various tools was an eyeopener. The stock cooler has little heat sink ability, it's pretty much up to the fan to try to keep the temps down under even a little load...and it struggles.  Eating even $1-2 extra on a better cooler, AMD (supposedly being gamer friendly) could have made a stock system setup far improved. But they didn't.

The cooling improvement with my little AOI is significant, esp. under system load. Now temps ramp up quite fast, plateau at ~76, then ramps down quickly. Right now, using CPUID HWMonitor sitting with some apps going: ~35 (current) 29 (Min) 76 (Max). The core speeds themselves vary ~3200-4200 (current) 137 (Min) 4276 (Max) MHz.

Along with what others say, your CPU can be whatever temp the cooler can provide. It just want to be cooled. If the CPU is defective or the cap is not right, internally it could spot overheat, but as a unit, its temp should be reduced by whatever the cooler can dissipate.

So with the issue, you're only left with a few things:

- The CPU is defective
- The cooler is defective (insufficient) or not installed correctly
- The MB speed ramps are incorrect for the cooler, allowing overheat

From reading your story, all these possibilities have been investigated. It usually takes a new set of eyes to find what you are missing in this conundrum. Otherwise you my not find the problem. Do you have a knowledgeable friend who could go over the system to double check your steps? It's always something, you only need to find it. Good luck!

PS. Another thought, using CPUID HWMonitor, you can see each core temp, as well as temps of pretty much every other part of your system, which may help diagnose the issue.

Re: Ryzen 5 3600, what should be the normal idle temp with stock cooler?

You need a few things. A digital infrared heat gun/reader available for about $15 these days from a hardware store. And/or download HWiNFO to see if the Windows temps are correct. Make sure you are reading in Celsius and not Fahrenheit, easy mistake. At 100c that CPU should shutdown. Throttling starts at 90c and the CPU should not boost period. 

If you're reading 45c less in BIOS, then the board isn't decoding to Windows properly or something because in BIOS you should be running hotter not cooler than in the OS. If the infrared is reading the same as what Windows or Ryzen Master reports, than you have a real problem. Bad CPU? Maybe. Improperly seated heatsink or too much/little thermal paste, possibly. Bad motherboard putting out too much voltage, possibly as well. Scalar set to 10X in BIOS can do it, PBO enabled, +200 boost, fan on the wrong header, etc. 

The best method of measuring a thermal issue is you are convinced everything is assembled fine is to use a digital thermometer (infrared) or thermal couples (harder to find) with a meter to get actual temps at the base where the heatsink meets the CPU. You can even measure the temp through the hole behind where the board mounts in that case for an accurate die temp. So my final recommendation is to get a tool to read the temp or check it with HWiNFO, make sure you're reading in Celsius or correcting from Fahrenheit. You need to troubleshoot if those readings are correct and what is causing them to be high. Articles online nor me telling you anything will lead to a clear answer since I'm not there measuring the temps or observing the assembly. 

Anything else is "shooting from the hip blindfolded". I can't just say, yep, replace the CPU or board. You'll need to figure that out and RMA the CPU/cooler or motherboard if that's your conclusion. I'd do better than MX4 as well, that stuff is not good, but it's not causing these high temps either. Stop watching videos from guys that say to use MX4, they obviously do not know what they are doing. Fact, not fiction. Kryonaut, Thermaltake TG-7 or Artic Silver 5 are better choices.  Good luck man.
