Ryzen 7 3700x temps

[nJoy.]

I recently got myself a Ryzen 7 3700x CPU. Really happy on how it performs, especially after my i7-2600k system. Only problem is temperatures. On idle it sits from 30-40C. Why those jumps? And they are constant. I've attached a screenshot. I am overclocked to 4.3GHz @ 1.35v on all cores. Any thoughts? Is this normal? My cooler is Kraken x62. I think it should be able to keep up with the R7 3700x.

Thansk for your replys

Idle temps are meaningless, from 30Cº to 60Cº there's virtually no difference to the CPU functionality.

 

The fluctuation might simply be that your "idle" is not so idle and you got something on sideground/background using resources.

 

Just stress test it and check your max achievable temps, those are the only that matter.

Just did. stays mostly stable around 90c but it did jump almost to a 100 couple of times. This is results of CPU, FPU and Cache stress test within about 20mins of testing. It looks like it did something during those spikes, I just never seen that other tasks could result tempreture jumps up to 10c.

Temps do look high.

 

Have you tried disabling the OC and just using PBO from Ryzen Master?

 

How's your ambient temperature and airflow through the case looking like?

 

Is mounting looking all correct?

Did you set up your fan profiles? It might be running in a silent mode and ramping around 38c

Ambient is about 19-20c. I did try all sort of settings for OC, it does get cooler. I've got NZXT H700. 3x120 stock fans as intakes in the front, 3x140 as exhaust (two of them are attached to radiator). I did remount my pump, it looked all good.

I did fiddle with them. But now I pushed them little bit more. Didn't affect temps alot, but I did reduce voltage from 1.35 to 1.322, looks stable for now. Temps reduced little bit. It never reaches those tempretures, only in aida stress test.

Anything more then a 3600 just beats on aio's. They just don't have the power to cool that focused heat from 7nm.

 

Dapending on your ambiant your temps seem slightly high but nothing I would see as a problem. I tested a 3900x stock cooler n a h115i and those temps were in the 80's. Given its a hotter cpu it also had a little bit bigger radiator and was only running about 4ghz.

 

 

Same cpu on a custom loop 4.6ghz 1.38v was hitting 72c load. 

 

 

 

I would look into a better cooling set up. Second gen Ryzen runs hot. And anything higher then a 3600 just beats on aio's after they heatsoak. Small volume of liquid along with a very low flow rate is not good.  You could put some fans in push pull. Undervolt a little bit more and a few other tweaks. Lower soc voltage and a few others but your really going to be fighting an uphill battle.  

 

 

Also keep in mind I found temp monitoring on Ryzen to be all over the place. I seen as much as a 10c higher reading when looking at different software.  I don't know if your aio has a temp probe in the loop to show the liquid temp but how warm is your liquid? No probe how warm are the lines? Are they just warm or are they holy crap that's hot. Aio lines on my 3900x were alarming hot. 

 

Love Ryzen they are great cpu's and  glad to see  AMD back why Intel is just spinning in a circle but these things run really hot. My first impression was flashbacks from the P4 days lol

My air cooler is similar enough in performance to a Kraken X62 and handles my 3700X very easily. Load temps around 70C, below that for actual use case stuff like gaming.

 

The cooler isn't the only factor influencing CPU temps though. Case airflow and to some extent ambient temps also matter. With AIOs, how the radiator is configured also matters (and the case of course impacts that).

What rpm are the pump and fans running at?

I am thinking on doing custom loop, just need to save some money :D. My liquid got to about 40c i think at most, but I did pushed fans to a higher RPM so it wouldn't get that hot. Also I've set them so they would ramp up as the liquid warms. Because with those temp jumps I don't like how it ramps up every couple of seconds.

My case isn't that great for air flow. It's NZXT 700 with 3 120mm stock fans in front as intake (also there is dust filter in front), single 140mm fan as exhaust at the back. and the AIO is set on the top with 2 140mm fans as push configuration.

It's set at constant 60% about 2120rpm. I did that because when I did search for info all I could find that pump speed doesn't matter (or is it otherwise?). For the case fans is mostly controlled by motherboard, but I did increase the speed by atleast 10%. For AIO fans I will add my curve as a picture.

Pump speed can definitely have an effect on performance. Trying setting it to 100% and check if the load temps drop. 

Your fan speeds are low considering that the liquid temp shouldn't get that high to begin with. Either use the cpu temp for the fan curve instead or max the fan sooner. For liquid, 100% rpm should be closer to 60c as opposed to 95c.

I tweaked the settings, so now CPU reaches 80c. Pump speed didn't change anything though. Nor liquid temps, nor CPU temps.

70c its  not really handling it.  Thats pretty hot. 80c is extremely hot those  little turds just dont have the power. whats your liquid temp at? 50c+

 

Real loop on a 3900x

I mean AOI's are trash. They can keep up till a 3700X  then they just get beat on because they dont have enough liquid in the loop and the flow rate is pretty much non existent.  Thats a 3900x on a single 240 raid also.

 

 

 

90's is high but not super high. those aio's typical temps are around upper 70's to low 80's.  Temp reporting can be skewed on ryzen.   I mean there not much you can do outside of fans at 100% and pump at 100%. You can do a push pull but the pump flow is whats killing you. Check out the flow on a DDC or a D5 at about 20% and compare it to a aio's pump at 100%.

 

 

If you really need the lower temps disable SMT and that will help a bit.

What world do you live in where 70C max temps in stress tests is “pretty hot?” I don’t have 3700X boost frequency numbers available to me, but if you look at 3900X the difference between a CPU handling real world workloads around 60C (and my 3700X is typically below that for gaming) and around 35C (an impressive result for real world cooling) is 75MHz.

And if you aren’t using the boost behavior and you’re just manually overclocking, it really doesn’t matter much what your temps are. Your clocks won’t be varying with Tdie.

Which settings did you tweak? What rpm are your pump and fans during load now?
