Ryzen 5 3600 95ºC

[Derek12]

Hi
I have the stock HS fan plus two intake cases (one in front and other in the side) and one exhaust fan

And when running cinebench the CPU goes to 95ºC with all fans at full blast mode, but never beyond that, the CPU throttles down to 3.8GHz but never below that at least in a Cinebench session.

I double checked the HS and it's tight and I've removed and installed again with same results

Is it normal? I have seen mixed responses all over the internet, some say yes with the stock fan, and some say no, because 95 is the max temperature, and I'm so confused.

PD: Idle temps are around 40-50c
Many thanks

It's high, I would repaste using different thermal paste. If it's a gaming/general purpose rig it won't be a problem, since you're probably loading in the 60-80 range, but if you're running heavy loads regularly on it I would want it somewhere in the mid 80s or at least below 90.

The included wraith stealth cooler is just very crap. Just grab a cheap tower cooler from somewhere, lower temps will allow the chip to boost higher too.

100%. Ditch that wraith for something like a cheap Hyper 212 Evo. It might not look as sleek as a Noctua or a be quiet!, but it's more than capable of handling the thermals of the 3600. It can also be had for about $30. Cinebench will stress the CPU more than most applications, but even if you're running in the 80s during normal use cases, you're at risk of never taking advantage of your CPU's boost clock, as it will throttle its clock speeds to protect itself.

Thank you all
I am using the preapplied thermal paste (I had a tube somewhere but I misplaced it, if I find it I will repaste and check if it gets lower.
I will use this computer for gaming and working (but the games I am currently playing are not CPU hungry and it runs about 70 but the load is very low).
I will try to pick up an aftermarket HS, maybe that Hyper 212 Evo or some Noctua that is not too big for my case (my case fans are Noctua and they are very fine). But as I am in the eve of upgrading to a M2 SSD maybe I will pick up a cheap one

I have a Noctua NH-U12S running in a little mATX case. It will fit in just about any type of tower case, except for ITX.

Sorry to say this, but you have a crappy case with extremely low air flow. An 80 mm exhaust fan isn't going to cut it, and who knows where that front fan gets it's air from.

Also, it's limited to a CPU cooler height of 156 mm and the CM212 is 158 mm. I know from experience that those old, top PSU designs just don't work with modern hardware.

Edit: The front fan gets all of its air from the small finger hole cut out at the bottom of the front cover.

Yep I had to choose a small case because I didn't have enough space for a full ATX one in the desk
The case font panel has a hole to draw air to the fan

I though with my current HW the airflow was enough (with my previous build, i3 6100, same GPU in a way worse case without intake fans and never got beyond 70 at full load, but I realize the 3600 is way more powerful than that.

Also it's a bottom-mounted PSU case better than a top-mounted one? I though PSUs were designed to act like a exhaust fan for the case

Then maybe I will have to look up for a low profile HS that doesn't clash with RAM, because the Noctua NH-U12S is also 158 mm but I don't know if an aftermarket LP HS is better than the Wraith stealth

You don't need a full size case. Just a case with an actual airflow plan, like the FD Meshify mini C.

my 3600 (with kryonaut) runs at around 86-90°C in a well ventilated case.


buy yourself any cheap tower cooler for 20-30 bucks and you'll be more than fine

 

[thebluebumblebee]

The Pure Rock 2 from be quiet! will fit your case and is one of the best values out there. The CRYORIG M9i used to be about $20, but their price has more than doubled.

Wraith Stealth + restricted case air flow results this. 95°C is the max operating temp so its normal to throttle there.
Start with a better case regarding air flow. Getting a better cooler will have minimal impact if the case cant move the heat outside quickly

 

[TheoneandonlyMrK]

The chip is designed to use the absolute effing max available to it when asked, it's just that simple, better coolers help but not as much as most would like.

That's about what I saw too with mine too with PBO.

With what cooler?
CPU stock settings?

 

[Derek12]

Thanks, I will check those HS recommendations
Another thing I noticed is that temps go up and down so fast, for example, running cinebench it takes a few seconds to get to 95ºC then stops there and stopping it it drops to idle temps in less than a minute
but any small load makes temps go up by 10 or 20c in seconds and that cause fans to rev up and down constantly
Is this normal in Ryzen with stock HS? Anyway I will buy thermal paste and check and if things don't improve then a new HS that fits in my case

PD: I also check and the case, and exhaust fans don't seem to be particularly hot, and MB temperature is at 30ish temps (almost the same as idle) and touched the HS and it's almost cold I am starting to think the temperature measured may be wrong (the HS is well tight until the screws stopped) or the preapplied thermal paste is just toothpaste.

Yes it's normal all modern x86 processor's with many cores work like this they're small packages with massive heating potential

Ok, on HWiNFO check the temps on the CPU Enhanced section.



Your cooler is using the (Tctl/Tdie) temp to regulate fan rpm. This temp is the hotest spot of all cores so its very normal to jump around like crazy. In order to avoid constant rpm up/down you can set a different fan curve or/and introduce some delay for fan to increase/decrease speed (usually called delta temp). 3~5°C delay can make a difference.

Thanks again to all!

This is what is get, seems to match the CPU Package temps except for the decimal but in some cases there are differences so you are right!
I saw on my Bios there is an option to specify the seconds to rev up and down and enabled that for 20 secs, seems to smooth out the fans pretty well

BTW, 87W maximum for the package, isn't TDP 65W??

 

[Keullo-e]

Like said already, the stock cooler sucks. I've actually never tried that on my 3600, but as I used a similar one on my old 2600 for day or two, it just sucked.

Just get a basic aftermarket cooler like already suggested.

What concerns me is that you dont feel your cooler hot. During CB R20 and CPU is 95°C the cooler should be very very hot if contact to CPU IHS is proper.

Off topic,
You're running your RAM at 2400MHz? Thats what I see for your memory controller(UCLK) and Infinity fabric(FCLK)

 

[Deleted member 193596]

the stock cooler from AMD... completely stock settings

 

[HD64G]

To make it limit its wattage to 65W you need to get in the UEFI settings and disable the auto setting and select the limit yourself. It will help muchly in thermalas and will lose less than 10% of performance.

I see, thanks!

Going from (PPT) 88W to 65W, I think performance will drop more than 10%.
Never tested it though. But he can try several things to temporarily cap its power consumption and heat dissipation.

Until he shorts out this issue there are many ways to constrain wattage and temp.
He can lower throttle temp to any desired value, or lower PPT again to a desired level or constrain the CPU indirectly by lowering the EDC value (I would guess around 60~65A).

Yes, I was thinking the same, but maybe I am not touching well because I have very restricted space for my hands, anyway I will repast it and check!

That's correct, I have two Corsair vengeance LPX DDR4 2400MHz
