Set core voltage to auto to resolve high idle temps.

These CPUs will boost themselves within the acceptable thermal and power limits. Unless you’re approaching 90C at full load then you don’t need to be concerned about temps.

 

Unless you’re approaching 90C at full load then you don’t need to be concerned about temps.

I always thought it was at 70-75C where the CPU starts taking damage. Can anyone else back up the 90C idea? If that's the case, then why is everyone quoting 60C for ideal temps?

 

Where are you getting this info regarding damage at 70-75C?

60C full load requires some serious cooling. People are either stating 60C as optimal because they’re considering the boost characteristics of the CPU (which will opportunistically boost performance depending on temp + other things) or they’re regurgitating something they don’t understand.

The best thing you can do for your CPU’s longevity and performance is get rid of that high static vcore you’ve set in there (1.32V). Set it to auto and let it manage itself for the best outcome. They’re not intended to run at high all-core voltage under heavy load and you’re also hindering the boost characteristics with it.

I searched online and found an article by Noctua which should ease your concerns about temperature.

Why is my CPU temperature so high?

Please note that results in reviews might show different results as many tests are conducted in open test bench configurations outside a chassis, which allows a better supply of fresh air and thus allows the coolers to keep lower temperatures tha...

Auto would set it to 1.45v. Remember it is an ASUS ROG board we're talking about lol.

As for the 60-65 C target temp, I've been seeing it used on several YouTube vids by Steve from GamersNexus and Linus Sebastian. Like you said, it is an "optimal" temp so I've been focusing on hitting that.

 

Or as an alternative to the Noctua article, the AMD product page for your CPU also states 95C max temp.

Anyone got any further info on this?

 

What kind of thermal paste are you using?

 

So I did some tweaking and I think the culprit was ASUS's Core Performance Boost setting. I also believe that ASUS might have removed PBO from the C6H BIOS as of May 2019 and left the removal undocumented (typical ASUS move imo). I was already thinking of buying a new board, so I'll probably just do that. The chip is stable now at the base clock of 3.6 GHz with an auto set voltage of around 1.0-1.1v. This will meet my daily needs until I can get a new board.

Thanks everyone for the help!

 

I'm getting 40-45 C at idle with it boosting to 70-75 C while running Folding@Home or Prime95

Just for the record, when I had my 3700x system with B450 MSI motherboard, my temps idled around 30C-32C in BIOS and Windows. Gaming temps were around 60C-70C at most. I almost never got above 75c ever. The only time I did was when I tried Prime95 and I got up to 85C for a brief second. And all with the stock Wraith Prism cooler.

CPU cooling isn't just about slapping a cooler on. It's also about great case airflow and good ambient temps.

 

my 3700x@4.3ghz with 1.29vcore with a barrow am4 water block and a thin 360 rad and a rx240 rad hits about 60-65tops under transcoding on plex and high loads running a 7dtd server likely wouldnt break 50c gaming,.

 

Would 720mm(240*3) rads keep the 3700x in the 50-60c range or would 840mm do the trick? 2(240)+360

 

That CPU on stock with Auto vCore and no PBO/P-State OC should only need like 1.05-1.1v to run the stock 37xx MHz lol.

A Gigabyte X570 Elite + 3700X my mate has cooled by a Kraken X73 runs like 49c load at stock 1.085v and with PBO it runs 4250-4300Mhz all core at 1.380v around 77c in Prime95 AVX.

 

Lol it's a stock cooler what do you expect? Them temps arnt bad.

 

They are bad compared to my temps that I posted above. Oh, and with the stock cooler as well. I was getting excellent temps and zero noise.

 

I've gone back to Air cooling with a Noctua NF D15 Chromax and couldn't be happier considering it's on air.
I'm running 24/7 all core clock of 4.4ghz/1.27v, 3800Mhz/1900 FCLK, 18-22-22-39/1.35v.
Temps in idle hovers around 35c, load under gaming between 50-55c, CinebenchR20 runs around 68c.
I've got one of the new revisions tho, build date on my die says week 45 in 2020 - just upgrade my platform.
Heard there is some major difference on early bins vs later 2020 bins - might affect your results.
