Question CPU almost hits 100 degrees when STARTING games ?

[PCTDROOD]

Hi guys!

I just built a brand-new PC with the Ryzen 5 7600x. My specs are as follows:

CPU: Ryzen 5 7600x
CPU cooler: BeQuiet! Pure Rock 2 FX
Mobo: MSI B650 Mag Tomahawk wifi AM5
GPU: Powercolor RX 6800 XT
Ram: GSkill Ripjaws 2 x 16 GB 6000mhz
PSU: Sharkoon Silent Storm Cool Zero 850W
Case: Phanteks Eclipse G300a
Storage: Samsung 980 PRO M.2 SSD 2TB

I've used CPUID Hardware Monitor PRO to check on my temps, voltages, fan rpms, etc. I've played AC Blackflag and Hogwarts Legacy to see what happens. What I've noticed is that when I'm starting up the games my CPU usage jumps to 100%, max. clockspeed is between 5900 and 6200 mhz (little high for the 7600x?) and temps approach 100 degrees (96.4 for Package, 98.9 for CCD #0). Then when I start playing it starts chilling between 50-65. My GPU temps hang around 50-70. Now the latter seems fine, but what on earth could be causing those mega temp spikes when I am starting up my games?

There was thermal paste already applied to the CPU cooler and I read online that I didn't need to remove and apply my own. I suspect there is a voltage or/power/clockspeed issue that needs fixing in the bios... not sure.

For reference, when I download games via steam (using on board wifi @400-700mpbs), the temps on my CPU also sit around 70-80, which I find a bit high as well.

All of my games run on a very fast SSD, I've also read that CPUs can be overwhelmed if games can be booted/read too fast because of the insane speed of an SSD, might that be the issue?

The case has three front fans, one on the back, two aimed at the top, so the airflow should be good.

Any ideas or tips?

Be sure you have the latest BIOS update for your motherboard. AM5 has had issues with CPU burnout. Latest BIOS fixes it.

CPUID HWMonitor has a tendency to exaggerate peak values (it says my 7950X reaches 6.5GHz on most cores). I doubt your 7600X peaks at 6.2GHz. It's just HWMonitor getting too enthusiastic.

Similarly, I'd knock a few degrees off those circa 100C figures. In any case, the 7600X should start to throttle at 95C.

As for the 100% usage and high temps when loading games, I checked the spec of the cooler and it's rated at 150W, whereas the CPU is nominally 105W. Despite the 45W of headroom, with only 4 heat pipes and 1 fan, the Pure Rock 2 FX looks a little "light" to my way of thinking (I prefer really big coolers).

The Pure Rock should be able to do a perfectly good job of keeping your CPU cool. It might be worth checking to see if the cooler is mounted correctly. If this involves removing the unit from the CPU, you'll need new thermal paste.

Do you have PBO applied? If so, switch it off and see if the temperatures go down slightly. It can be a little confusing to work out if PBO is enabled or disabled in some BIOS. I think that when PBO is set to Auto in the BIOS, it means PBO is switched off.

I just updated my bios and restarted the pc. Started downloading a game to see how the temps hold up and they shoot up to 90 degrees again. After the download it's fluctuating around the 70 degrees. Bios update didn't seem to fix it.

Use HWiNFO version 7.60. You'll probably find it reports the temperatures and frequencies more accurately than HWMonitor.

Downloaded it and booted Hogwarts Legacy (seemed like a demanding game for CPU and GPU). Found that it spiked to ~95 degrees again when booting + loading shaders, then I played and it fluctuated between 65-75 degrees, which is FINE.

Could it have anything to do with my M2 SSD? I tried to set a thermal limit, but then my PC crashed. Then I disabled PBO, but that did nothing. I am considering to undervolt the CPU, should I? It keeps saying the core clock maxes around 5-5.4Ghz, which is still higher than the 4.7Ghz that was advertised.

I logged the HWINFO thing and logged it, but it's an CMV file. How do I share that here so you guys can see the stats?

Edit:

Someone said this in a different post:

[START]

If you want to see if boosting is causing the system to idle at a higher temperature, then do the following:

• Open a command prompt as an administrator
• Type in powercfg -attributes sub_processor perfboostmode -attrib_hide
• Open the Start Menu and in the search bar, type in "Edit power plan"
• Click on "Change advanced power settings"
• In the pop-up window, go to "Processor power management" -> "Processor performance boost mode" -> set the "Setting" to "Disabled"

[END]

I did that, because my Processor Power Management was set to 'aggressive' (made me LOL). Now that I disabled it, the process I described above lead to temps between 45-50, which is LITERALLY HALF the temp. PBO still disabled in the bios, but I figured I didn't need to change that anyways now that this works, right?

I have to ask, but does the brief excursion up to 95C cause any perceptible instability? Are you worrying unnecessarily? So what if your CPU reaches its throttle temperature for a few seconds? That's normal for modern CPUs.

I ran my 7950X at a constant 89C for 36 hours without any problems on a 4K video render. The room got warm with the heat from the CPU and GPU, but nothing untoward happened. I don't have PBO or XMP enabled.

I guess that theoretically it can't hurt to hit 95-100 degree temps for short periods of time, but it's a mental/peace of mind thing I guess. The uncertainty of why it did what it did was bothering me a lot. I know the 7000 series runs hot and I know these CPUs (or most of them) are perfectly capable of withstanding heat like this. Simply put: I just prefer a slightly slower clockspeed if that means my temps go from 95 to 45 . Thanks for your help on this thread.

Those new processors will try to boost as high as possible till they hit the thermal limit it's normal for them.

As others have said, it's totally normal for these 7000 series cpu's to hit their thermal limit, they are designed to do so. Give this a watch though https://www.bing.com/videos/rivervi...E077B00C2055E7A0045FE077B00C2055&&FORM=VRDGAR
