Hi guys,

3900x here on an MSI x470 Gaming Pro. All latest bios updates, chipset, windows updates etc. Bios is all totally standard setttings apart from XMP on my ram.

I've noticed that mine is idling around 55c on the wraith rgb cooler. Repasted with noctua nt-h1 and lost about 4c.

I investigated further and it turns out even in windows, my 3900x clocks don't go below around 4ghz at any time, even with task manger saying 2% cpu usage.

Anyway I can solve this to get lower temps?

Thanks

You said in your OP you were stuck at 4Ghz, not 1.4v vcore, which is it ?
The only reason i can think of to be stuck at 1.4vcore is that you have it set in the bios ?

Vcore is minimum 1.375 that i've obseverd but it's almost always 1.4+ which is probably why it's idling so hot all the time?

I haven't set anything in the bios at all. It's set to defaults and after the last bios update, I reset everything back another time just as a precaution.

Speed wise, every core is always in use, none are being shut off (attributing to the abnormal idle temps?) They all range from 3.8ghz - 4.455ghz.

This is on the amd balanced plan. Stock settings and just idling in windows. Seems that HWmonitor was being a bit overzealous with the reports but it's still not right to be idling this high.

Task manager says everything is fine, 2% cpu usuage. Nothing looks out of the ordinary

Try resetting motherboard BIOS to default (optimised) settings and check again.

No change. Did notice the bios reporting the cpu temp as 41c and sys temp as 34. Lowest i've seen them. Soon as windows loads with ryzen master, we're back to 51 - 61 idle.
 
Potential motherboard problem perhaps? It's still under warranty.

I cant' fault the performance of the 3900x at all it's just it's constantly 50 - 60 idle. Using the RGB Wraith cooler which can't be that great and I know how to paste correctly. All my intel chips were in the low 30's idle!
 
Going to return the board. After much googling yesterday, it seems MSI are one of the worst for this.

Found pages and pages of people on MSI x470, x570 and the b series all experiencing the same on MSI boards. Most of them swapped to a different brand and haven't had any problems.
