CPU Usage & Temp are TOO HIGH while gaming
Posted by ZX1FE@reddit | buildapc | View on Reddit | 34 comments
my Ryzen 7 7700X is running at 95°+ and 70-80% usage while playing warhammer 40K Space Marine 2,
i want to know if this is an issue? and if so how can i probably fix it?
TimmmyTurner@reddit
what CPU cooler are you using
ZX1FE@reddit (OP)
Redragon effect CC-2000
TimmmyTurner@reddit
that's a pretty weak cpu cooler. go upgrade to a phantom spirit / peerless assasin.
jackdupondew2k5@reddit
This is the big question that needs answered. My 7700x3D never gets anywhere close to 95c never goes above 70c under full load. I’m using arctic freezer 3 360mm aio though
No_Guarantee7841@reddit
How about starting with the cpu cooler you are currently using?
ZX1FE@reddit (OP)
Redragon effect CC-2000
No_Guarantee7841@reddit
Yeah, thats not gonna cut it foe that cpu. Either undervolt or get a better cooler.
ZX1FE@reddit (OP)
what cooler can i upgrade to?
TheDutchTexan@reddit
You can't do a thing about the CPU usage, there is a lot going on. But the cooling? Unsure what solution you are running but you might look into a bigger air cooler or maybe a nice AIO if you like liquid cooling.
ZX1FE@reddit (OP)
my cooler is a Redragon effect CC-2000
Penrosian@reddit
You are fine. That's what your cpu is aiming for.
Although I am curious: what cooler are you using? My 7800X3D doesn't really get over 80-ish (since i last checked) under load using a peerless assassin. Then again the load i am referencing is barely multi core so that may also be it.

im using a Redragon effect CC-2000
SebaBennett@reddit
7800x3d TJ max is 89C and 7700X is 95C, its not comparable.
Penrosian@reddit
Mine still runs more than 10 degrees under spec, so it kinda of is. Still doesn't change the fact that I want to know what cooler they are using.
SebaBennett@reddit
Does it run under spec while running cinebench? i've never reached max temp otherwise.
Penrosian@reddit
I turned off afterburner when I ran cinebench after i first bought it to try to eliminate as much load as possible, so I would have to check when I get back home in a few days. !remindme 3 days

Space Marine 2 is a pretty cpu intenseive game so its normal for it to run hotter and at a higher usage than other games.
95C is the limit that AMD said was safe for operation but I understand it makes a lot of folks uncomfortable.
What case and CPU cooler are you using? Do you know the ambient temperature of the room your PC is in? Any idea what the power consumption of the CPU is while playing this game?
A few easy ways to lower temps in the BIOS.
-Go into PBO settings and change your max temp to something your more comfortable with. You can also leave ECO mode off and limit the PPT to something less the stock 144W.
ZX1FE@reddit (OP)
my CPU cooler is Redragon effect CC-2000 and the case is an Msi Forge 320R, and i would guess my room temp is around 28°, i'd like to add that the cpu temp only reaches 95° in Warhammer, i tested it yesterday with cyberpunk and it only reaches around 85° max
Rickstamatic@reddit
Do you just set the ppt to 95w and leave the other two numbers at default or do find an in between number for those too?
b-maacc@reddit
I left EDC and TDC alone.
superrob1500@reddit
95C is the thermal target AM5 chips aim for. It's not bad as long as it's at 95C and not going over often, it means your CPU is working at is best. As for utilization, unless the high utilization is affecting your FPS output, I would not worry about it.
ZX1FE@reddit (OP)
people were telling that more than 90° is bad for your cpu and would shortens its lifetime
VLAD1M1R_PUT1N@reddit
This is a common misconception. Temperatures within the manufacturer specifications will not harm your CPU or affect its longevity. Voltage however will, the higher the voltage the faster degradation will occur. Even if you don't manually change it, many motherboards will default to more aggressive profiles that go beyond Intel/amd spec.
SACBALLZani@reddit
Isn't it a combination of both voltage and heat? I don't know in the context of am5, but for my Intel 11th Gen 1.5v should be safe 24/7 assuming you're not hitting tjmax under load. Can't remember my exact voltage(not near my pc, my house in western NC still doesn't have power since Helene) but I'm definitely running close to 1.5v at 5.2ghz 24/7and my cpu will hit 80c max under load. Been that way for years and I still set new pb's on benchmarks
VLAD1M1R_PUT1N@reddit
Yes it's both, but again it's all about manufacturer specifications. If Intel says the tjunction for your 11th gen is 100°C, then anything under that is safe and won't cause any harm. Intel doesn't explicitly state the voltage limit, but lower is better, it just comes down to the silicon lottery on what your chip can handle and for how long. It's very possible that 1.5V is degrading your CPU, but only very slowly such as that your CPU will still outlive its useful life, ie it will only last 10 years instead of 20. Keep in mind that every individual chip is physically different and has different tolerances.
The_Anal_Advocate@reddit
Used to be a rule of thumb, which was a reflection of chip design at the time.
Generally the hotter it gets, the shorter the lifetime of a semiconductor. It gets very material science-y to go into detail, but the general rule of thumb for chemical reactions is every 10 deg C doubles your reaction rate. So in a gross oversimplification (Don't make The_Anal_Advocate talk about migrating holes) being 10 degrees cooler would double the lifetime of your silicon.
superrob1500@reddit
That can be true, depending on context. In the context of the AM5 family, up to 95C is expected under load even with good cooling. It should not be a detriment to your chip.
Even on chips where super high temps are not good, any noticeable lifespan shortening would from from borderline out of spec temps (100C+) constantly for a long time.

thank youu mate i was panicking there for a sec, what a relief
GnomoCS@reddit
Undervolt or watch some videos explaining how PBO works
Adjust the PBO so it doesn't overheat, you will lose a few percent in performance, maybe 4% but it will drop maybe 20 Celsius
the_doctor_808@reddit
Shouldnt be a big issue but if you want to improve it then just get a better cooler.
SebaBennett@reddit
95° is ok for 7700x, I've got one with a phantom spirit 120 evo and it still gets over there. I did PBO, -15 to each core and got a 80C thermal limit and it works just as good as before and much quieter.
Hope it works, if you like you can DM me and can help.

CPU tech changes with each iteration. What was true ten years ago just isn't today.
Modern CPUs throttle and scale as needed to give you both energy savings and power in pretty equal measure. They can decide, mostly on their own, to keep going faster until a specific temperature is hit, giving you the very best bang per unit of need.
And when there's nothing demanding it can go really, really slow.
If you get a better cooler you'll still have the same temps (up to a certain point, where it can't draw enough power to keep it there) while in a demanding use case.
Ten years ago boiling water was bad. Today it's not ideal. The solder won't melt until it's closer to 130, so it'll be fine.

95c is ambiguous in modern Ryzen CPUs. A 7700x at 85c can be 0.1% throttling or at maximum throttle.
It's like this: cinebench is a popular CPU benchmarking program, you can see the 7700x when properly configured and cooled should get a score of about 20k, a little less, https://m.youtube.com/watch?v=ghZaQ3T0CRg&t=512s, 5% difference is expected depending on many factors.
Modern CPUs use up all overhead automatically, your CPU boosts to 5.4ghz, what hapiens is rhe CPU goes to the base clock of 4.5ggz, checks the temperature and if there's headroom it gies to 4.6, 4.8, 5, 5.2, its checking temperatures snd the voltage and load every millisecond (look up "precision boost", say at 5.0ghz the temperature is 95c, the CPU throttles, it doesnt boist to 5.4, its out of thermal headroom. Your cinebench R23 score may only be 17k instead of 20k.
So you hit a better cooler, this time at 5ghz the CPU is only 85c, so it boosts more and more until it either hits 95c, or hits the max boost clocks of 5.4ghz.
Your CPU may be partially throttling or heavily throttling, the way to tell us by benchmarking it, if it's at 95c but you get a 19.5k cinebench r23 then it's fine! The CPU pushes itself to the limit and is within performance spec.
Now if you get to 95c and the cinebench score is only 16k then you know it's heavily throttling.
95c is the max SAFE 24/7 operating temperature, the CPU uses all headroom until it either hits 95c or 5.4ghz, automatically. If it's hot in your house it'll boost less, you crank the AC it boosts more, in both cases it's 95c but one runs faster than the other.
Wonderful-Poetry860@reddit
I wouldn't worry about it, tbh. 95C is within normal operating parameters for non-x3D Zen 4 CPUs which start throttling at 89C. You can try and under-volt your CPU to lower temps (less wattage used = less heat created = less heat to dissipate). Other alternatives for lowering temps would be moving to a case with better air flow, lowering your ambient room temps, or upgrading to a more substantial cooling solution than what you're currently using.
