Ryzen 9 5900x - High temps in idle (77-81°c)

[Renan_Longatti]

Hey!

 

Just bought a Ryzen 9 5900x system, and got a bit scared when in idle mode the CPU keeps an average temperature of 78°c. Working in just a few aplications it goes up to 85°. When gaming or rendering I get temps beyond 90°. The fans are always in full rotation, causing a very annoying noise for such simple tasks.

 

I checked some reviews and benchmarks, the average temps never went beyond 60º. Is that right?

 

 

My system:

 

Ryzen 9 5900x

WC Cooler Master MasterLiquid 240mm ML240L V2

TUF GAMING B550M-PLUS

RAM Crucial Ballistix 32GB 3200Mhz (2x16)

GTX 1650

 

My tests in idle mode:

 

 

I have 2 extra fans mounted in front of the radiator, so 4 fans in total:

 

 

 

I found no one with a 5900x reaching such high temps in idle. I can't trace what may be the cause. Is my cooling not enough? Maybe a thermal paste problem?

 

I'll be really greateful if you guys can help me solving this issue!

 

 

Thanks so much!

It sounds like either your pump from the AIO is dead or not plugged in / setup in bios, or there isn't near adequate contact between the CPU and heatsink.

 

EDIT: Also when installing the AIO, did you remove any plastic cover / film from the heatsink?

Could also be just a bad mount.
Check the block mounting. If you left anything on the block like suggested above, correct it and reTIM, remount it.

What about your front panel airflow? can you attach a picture of that?

 

What thermal paste did you use?

Look at his core voltage - 1.444V.

Only one of his cores is turboing, and the rest are doing nothing.

 

It's no wonder his temps are high.

Oh shit yeah you're right

[Beerzerker]

I see that now - He's probrably using either "Auto" settings or Ryzen Master itself is doing it.

Needs to change all that to about 1.25v's or so.

It's normal for an X cpu, i had mine up to 1.48 and at stock with PBO.

68c minimum tells me that the heatsink / waterblock is not in full contact.

Probably not evenly cranked. You never want "more" thermal paste, a rice size in every corner is enough.

It is perfectly normal, my 5800x goes all the way up to 1.5v on its own yet it does not hold such high temps

 

As others have said, it is one of these problems :

- pump not making contact with the cpu - bad mounting, protective film left on, toothpaste used for tim

- poor pump performance - air trapped in the pump, pump not plugged in or rotating too slowly, go check the pump rpm

- water temp creeping up with poor front airflow when idle

Thanks for the reply!

 

I bought the PC already built, as I don't have experience in building one =/

So I'm not sure how they installed it.

 

But I can hear the water pump working. So the problem must be the contact betweem CPU and heatsink

Here's the front panel:

I can try changing it. But yes, may also be a bad mount

Understood!

 

Will ivestigate this alternatives

You can investigate now, really easy to do, that mounting is foolproof, all you need to do is unwind one end so you can declip it from the base mount.

Once you can remove the waterblock, check out the paste pattern, if there's a big lump on one side, that means there's uneven distribution.

At this point all you need to do is examine if the paste are dried up or not, if it still have some moisture (i assume it does), you can put it back.

Now crank / wind both side evenly, turn it slowly until you have some resistance, and turn it half way.

Run the pc, check the temp, if it still hovers around 60c, turn it half way again, do this until you get around 40-50c which is the ideal idle temp for this cpu.

When you are satisfied with the idle temp, run a benchmark, i suggest Prime95 for at least 10 minutes, the temp should not be over 85c.

I'd put radiator at the top panel if it can fit,and install additional food airflow fans 2 as intake 1 as exhaust and then run tests.

I don't like your airflow at all.

The radiator best position is at the top if it could fit.

Def not normal for idle. Using the same cooler/CPU/auto (with different fans) idle is more 50C. Load temps can get into 80 degrees (mainly on CCD1) with same type of voltages you are seeing.
