Low idle temps High load temps

[yellow06]

Hey dudes,

I just upgraded to a 5800x from an i7 4790k and like with my previous cpu I'd like to do some cheeky overclocking but...
I've encountered an issue where the idle temps are sitting around 27C-30C but as soon as I chuck on something like cine bench it soars immediately to 90C.
Prime 95 only got it to about 60C but still said it was 100% utilized.
I'm using the cooler master hyper 212X until i find a cooler that I like and will fit in my build well (open to ideas) as well as thermal grizzly thermal paste.

At the moment I'm thinking maybe the cooler doesn't have enough thermal capacity, its not on tight enough or there is bad thermal contact.
Any ideas?

That's sounds pretty reasonable. If it was on tight enough or had other mounting issues, it would have higher idle temperatures. If you want lower temps you'll need a bigger cooler. That's a fine temperature for stock operations.

It's mostly just not a great cooler. It's passable and geta the job done for the most part, but the Zen 3 chips get really hot stock, so you just need a better cooler in general.

 

I'd go for a Noctua U12S or U12A. If those are a little out of your budget, you can do a U12S Redux. It has basically the same thermal performance as the U12S, but it's just noisier. There's good options from other brands than Noctua, obviously, like Be Quiet and Artic, but I'm not as familiar with those. Others may have some recommendations there.

 

As far as overclocking goes, I wouldn't bother. Ryzen CPUs haven't overclocked well for a while. Besides, undervolting is the better approach for Zen 3, anyways, now that AMD added the PBO2 curve optimizer. You might even be able to get by with your current cooler, properly undervolted, and you usually get even better performance to boot. It's not unusual at all to hit 5GHz single core with a 5800X undervolted via the curve optimizer.

If the case allows for it I'd probably recommend a fuma 2 or Mugen 5.

Thanks peeps I was a little thrown off cause of the insane difference but I'll be grabbing a new cooler some time next week.

I was thinking noctua and just saw the new video with the redux cause the extra noise doesn't bother me.

As for undervaluing ill give that a little look and maybe update how I went.

 

Again thank you legends

those temps are actually 100% normal so there is nothing to worry about. many people here will tell you that benchmarking puts your compouter thru a stress test and pushes your pc farther than what you would ever have it do day to day even hard core long hours of gaming.

 

if you want lower load temps then a better cooler would be recommended but for idle, its pretty much perfect.

That's 100% normal, even with a much better cooler you're likely not get much better results. I've managed to get it cooler temps changing the VRM settings and setting the clock speed to 4.7ghz, but stock even with dual 360mm rads. I'd get 85'c, though fluid remains at 34'c
