Ryzen 1700 at 94c under full load

So, according to Ryzen Master and MSI Command Centre, my CPU is running at 94c when under full load. And between 50 and 60 when idle. Is this right? Doesn't seem so. I'm sure I read somewhere that Ryzen shouldn't be going over 75c as it will shutdown?

I'm on the MSI B350 Tomahawk Motherboard with BIOS 1.3, and I've recently installed the new AMD Chipset drivers, 17.10 with the Ryzen power mode, however, it was runnign at 94c before installing the new drivers. I'm running the Wraith cooler that came with the CPU.

Anybody know if I'm getting false readings? Or if ym CPU is about to explode?

Thanks in advance.

Re: Ryzen 1700 at 94c under full load

Ryzen 1700, Freq: 3000 MHz, Turbo: 3700 MHz

Idle: 3200 MHz, Load: 2620 MHz

The Ryzen is supposed to throttle back you speed at 95C. It looks like it is doing so.

Are you overclocking your CPU? At idle it is 3200. MHz If so then you should set it back to default settings to see if that helps with temperatures.

Also, if you are overclocking and are want to lower the temperatures you will need a better CPU cooler.

Another factor is case airflow. No matter what CPU cooler you have you still need to effectively get rid of the heat buildup in the case.

Re: Ryzen 1700 at 94c under full load

Hello,


I haven't overclocked the chip, it's doing it everything by itself. Everything is on default settings.

I did give my fans a clean today, as the airflow wasn't as good as it could have been, and it seems to be running at a high frequency, while keeping the temperature just below 95. I'll attach a new screenshot.

I just thought maximum was 75 degrees, but the CPU seems to be happy adjusting the frequency enough to keep it less than 95, going between 2.8 and 2.3GHZ, so I'll just leave it.

Thanks.

Re: Ryzen 1700 at 94c under full load

Hi,

did you removed the stocked Thermal Compounds on the Wraith cooler and used your own (better quality) from Arctic, Corsair, Alpenföhn, etc.?

Because this stocked Thermal Compounds is mostly not the best one. And you don´t know how old this stuff is.

Re: Ryzen 1700 at 94c under full load

I forgot. The Ryzen CPUs will automatically run at a speed higher than the base if it thinks it is safe to do so. In your case it operates at 3200 MHz instead of the default base of 3000 MHz.

I think the maximum temperature is 95C. That would explain why your CPU speed is throttling back when it gets close to that temperature. Notice how it dropped from 3200 MHz to 2620 MHz while it was under load. To keep it from throttling you are going to have to lower the CPU temperature. It is definitely higher than it should be. I would expect an idle temperature closer to 30-35C.

I have a 1700X which I have overclocked to 3800MHz. Its idle temperature is 35-40C. I just ran Prime95 for 45 minutes. The max temperature during that time was 80C. High but still much less than the 95C maximum. The 1700X does not come with a CPU cooler so I had to buy one myself. I have a Corsair H60 which is not the best water cooler but is adequate for now.

I have an ASUS motherboard which has a utility to automatically overclocks the system. It started at 3850 MHz and stepped up by 25MHz. When it reached 4050 MHz the system crashed. I don't think it was a coincidence that the CPU temperature was just over 95C when that happened.

Re: Ryzen 1700 at 94c under full load

I didn't think to clean off the thermal paste that comes with it. Do you think I should get rid of it?

I've got a clenaing set called ArctiClean which can remove it. And some Arctic Silver 5 thermal paste.

Or can you recommend anything better?

Thanks.

Re: Ryzen 1700 at 94c under full load

Yes it's doing that, keeps changing the speed to make sure it won't go over 95c. Someone above suggested I change the thermal compound, so I might do that.

Re: Ryzen 1700 at 94c under full load

I always remove the stocked Thermal Compounds or  use another one. Once apone a time, I´ve bought a Alpenföhn (Gotthard). The Th. Comp. wich was by the cooler ink., was totaly dry and out of buisnes. You don´t know the date of manufacture of the cooler.  :-)

Arctic Silver 5 is ok. Anything better?...sure but this is (imo) a matter of taste. But everything is better the the stocked therm. comp. . I prefer "Schneekanone" from Alpenföhn. I got the best temps. with this therm. comp. .

To remove the old comp., I always use cleaning petrol. Thats enough. Don´t pay too much for expensive cleaning kit´s.

But, BTW...just use another cooler...I got a 1700x and a cooler from Arctic (Freezer extreme). Not the best one, I know. But I will wait till the market brings better cooler for AM4 Boards. My highest Temp. is 50° -  60° with prime95 after 30min. (without 20° offset). And the cooler is super quiet. I never hear this one. I payed 25€, for the cooler.

Re: Ryzen 1700 at 94c under full load

Bloody hell, that thing is huge! Not even sure if it will fit in my case.

Arctic Silver is all I have. Can you recommend another one? I was happy sticking to the stock cooler at first, but 95c worries me, so maybe I will splash out for another one and some really good thermal paste.

Thanks

Re: Ryzen 1700 at 94c under full load

Wich case you have? Just buy a good therm. comp. with a "better" coller. The boxed cooler are always a bit $hity

It fits perfect in my Phantom 410 from NZXT.
