Ryzen 5900x temps

[Devaniti]

I build myself a new PC with Ryzen 5900x and it looks like I seriously underestimated how hot this CPU is.

It's cooled with 240mm AIO, but it seems it's not enough.

HWMonitor says that it peaks at 91C, while drawing 170W of power.

 

Does that temps make sense, maybe I installed AIO wrong?

Or should I upgrade my cooling? Or 91C is fine for Ryzen?

If I should upgrade what is better to pick? Same AIO but 360mm one, or something else?
I'm not living in US/Canada, so my parts choice may be limited.

 

I'm also utterly disappointed in idle power draw which is around 50W for CPU alone. (according to HWMonitor)

My old PC running i7-4790 and tower cooler was quieter under load than new one with 5900x when idle.

Is it normal? Can I do something to improve idle power draw?

What is the average temp during gaming or whatever you are using it for? It could be a temporary spike, while it averages at a reasonable temperature. HWINFO tells you the average temp in their monitor.

It looks like I did really bad job when applying thermal paste.

CCD1 is hot but CCD2 is fine.

Will try to reapply thermal paste and check temps after that.

Oh, wait, it's just game was running on CCD1, running Cinebench makes them equally hot.
Will have to test it some more before jumping to conclusions again.

your aio is so so. but check paste spread (if the the cooler didn't come with it pre-applied), mounting pressure, and pump speed. 

how is the rad mounted in the case?

Also

what case are you using?

you may also try dropping your cpu voltage. if you can get to 1.3v or low without loosing performance you should see a good temp drop.

 

don't run multiple monitor software. just use one. HWinfo64

Thanks everyone for help.

It turns out problem was fan orientation, all of the fans was blowing air out of the case, reverting case fans to be intake fixed temps.

Now during cinebench multicore test temps avaraging at 65 with spikes max to 70 degrees.
