Ryzen 5 3600 Temp spikes on idle

Recommended Posts

Posted · Original PosterOP

Guys,

 

I've recently completed my ryzen 5 3600 + msi b450 tomahawk build.

 

Whilst gaming, the temps are a steady 60-68 degrees. However, in idle, it jumps from 35-47 in 1 second randomly. This can't be okay right? Anyone have an explanation/fix for this? I'm using ryzen master as a monitoring software. Also used CPU-Z, HWMonitor etc. All saying the same. Its just jumping from 35-50 and going back, then 50 again etc. This is with 2-5% cpu usage. 

 

Thanks

 

Edit: My cores are always on 4GHz aswell. The cores keep jumping in idle.

I’ve had this with my 2700x too when I had no OC applied. Really odd

You saying OC'ing should fix this?

Could this have anything to do with thermal paste, or is this software or bios related?

Because on idle its 32 minimum, it just keeps jumping. voltage @ 1.4, etc.

As long as you aren't having any problems because of it and your load temps are normal then I'd say it's nothing to worry about.

If you ask for a Mid Tower case recommend, I will 90% of the time recommend the Fractal Design Meshify C or S2.

Not saying it’s fixing anything.

 

i think it might have to do with the PBO of ryzen. I just noticed once I manually OC’d it it didn’t happen anymore.

This is normal with Ryzen 3000 series due to Precision Boost Overdrive. My 3700x goes from 35 up to like 55-60c at idle due to PBO.

Had the same problem. Turning on high performance in power options seemed to help slighting with fans ramping up due to heat spikes, they are now relatively quick spikes, ill probably play around with overclocking to see if it helps as ppl r saying its to do with PBO, but so far using the high performance power plan seemed to help.

Even with PBO off (I've set it to off since day 1) it happens.  It's just how it is.  It's just random processes pinging the CPU and the CPU responding to it by boosting clock speeds.  You'll see the temps never last more than a few seconds.

When there is no danger of failure there is no pleasure in success.

Also got a 3600x i had high temps even with my Cooler Master Hyper 212 Turbo LED it will idle around 50up the solution i found was to under volt and under clock used the bios and did it manually 

i went to bios and put my Core clock to 4.2ghz and the Cpu voltage to 1.3125 after that i kinda got improved performance on the cpu and better idl temps 

now it idls at 36 degrees to 40 it's much better than before.it seems like the sweets spot for the 3600x
