New Ryzen 2600x build, Temps High on stock clocks

[Daveeede]

Hi guys, I just built a new PC over the weekend with the following parts:

-Ryzen 5 2600x

-Stock AMD cooler

-ASRock B450M PRO4 motherboard

-Team Vulcan 2x8gb (DDR4-3000)

-Seasonic 520W Bronze PSU

-Thermaltake H18 Versa Case

-Shitty mechanical HDD I had lying around

-Old ass GTX 750 I had lying around

 

I was running AIDA64 to get an idea of temps and quickly saw them shoot up to 95 deg within a minute or two. I figured I had mis-installed the cooler so I took it off and put new thermal paste. This didn't help. I then realized there was a glitch with the CPU fan speed that caused it to run at 40% speed all the time. I found the issue and was able to fix it and apply a proper fan curve. After this, temperatures sat at 90 deg or so after a few minutes. This is still too hot for my taste.

 

I decided to dial in a custom clock speed and voltage because I saw through HWmonitor that voltages were over 1.35 V! Found a stable clock of 3.9 GHz on all cores @ 1.1625 V and temps now sit at 70 degrees. This is an ok speed but I'd like to at least get what I paid for in terms of stock clock speed. I tried 4.0 GHz on all cores @ 1.2V in Ryzen master but I am noticing that it isn't stable because the voltages aren't going up to 1.2V in HWmonitor. They are capping out at 1.136 V and then the system crashes. 

 

Has anybody experienced a similar situation? I don't want to buy a new cooler if I dont have to. The case only has one exhaust fan right now but I plan on adding a few intakes to help it out. I'm thinking of just getting an Arctic Freezer 33 cooler and running stock/auto clocks because I really dont have the patience to play with clocks? The ssd I ordered hasn't come in yet and the HDD is toast so restarting each time is like getting my teeth pulled. What do you guys think I should do? Should I just keep at it?

Turn up your LLC settings to the middle level. Basically you would want to make the voltage at idle and under load the same (not necessarily what you entered in).

I was able to set a -50mV voltage offset in the BIOS. This has helped temps a little and hasn't affected stability. I am realizing that I really need more case fans though. After 10 minutes of encoding a 1080p video file in handbrake I was peaking at 87 deg. The motherboard was pushing about 1.25V to the cpu set at stock clocks (3.9-4.0 GHz all cores). Gonna add some case fans and then see how it goes.

ya, i'd be more worried about the vrm than the cpu on stock clocks, 4.0 all cores tho

I dont think those temps are normal. I own a R5 2600 now and used to have a R7 1700 and neither cpu ever exceeded 54 degrees C with stock speeds and stock coolers under heavy load. Then again, The 2600x runs at higher stock speeds and both my chips had a TDP of 65W. Also keep in mind it takes a couple weeks for the thermal paste to "cure" and reach its maximum effectiveness.

Added 3 case fans and my temps fell from 87 to 80 degrees during the same video encode at the same voltage and clock settings. I'm starting to think that the included AMD fan is just not strong enough for this chip. The chip is using 120W of power according to HWMonitor so I think an aftermarket cpu cooler would be more suitable for a heavy user.

I guess it depends what type of usage the PC will get. If I was encoding often I wouldnt want to have my cpu sitting at 80 degrees for hours at a time. But I don't think it will get that hot in a game or in regular usage.

A little bit off the main topic, But what kind of performance difference did you notice going from an i7 4790k to Ryzen 5 2600x?

I’m still going to be using the 4790k as my main rig. The ryzen system is going to be for someone else.

 

The 2600x is definitely more powerful, but I think it depends on the type of use case. I can’t imagine there’s be any difference in a gaming scenario since they have about the same single-core performance. The i7 might still pull ahead a little here if anything. Haven’t tested this much. 

 

For rendering or encoding the 2600x shines. I get about 900 in cinebench on my i7-4790k when OC’d. The 2600x gets 1350 on stock clocks.
