75C too hot?

Recently upgraded to a 5700X on a Tuf X570 mobo. Getting load temps of 74 - 76C when gaming. Cooling is a H100x AIO
Is this normal, my old 3600 on a B450 board got to around 65C and that was on a cheap arctic tower cooler
 
Yea it's normal for a Zen 3 chip, nothing to worry about. If you want to bring that temperature down though you probably can by twaeking the power settings and playing with the 'Curve Optimizer' ....which I would look up how to do as if I explain it here I'll be typing for the next 30 minutes at least probably.

3600s ran cooler than the zen 3 chips, certainly than the 8 cores ones which have very dense single CCX designs, your 5700X runs a few degrees cooler than my 5900X and my 5800X. The 5900X is totally default but the 5800X I've tuned with the Core Optimizer to get it's temperaturs under control, reduced the power the chip can pull and given it a 15% negative boost curve, which actually leads to it hitting higher frequencies for longer and thus gives me more performance as it stops it hitting it's thermal limits, the chip is just being given more juice than it actually needs to hit it's higher frequncies by default and so heat becomes the limitting factor, by reducing power to the chip you can reduce heat and actually increase the performance and make the cooling load on the system easier. Without turning my 5800X like this, which also uses a single CCX as it's an 8 core chip but clocked higher, it will hit 90c in the NR200 mini ITX case I have it in with a 240mm AIO, what I have done drops 10c off it just like that, I could probably get more but I don't feel the need to, I haven't had to do that for the 5900X as it runs cooler anyway due to it's less dense twin CCX layout.

those temps seem high for a 65w cpu but depending if the cold plate is centered over the ccx or if its centered over the entire heat spreader. what are you using to stress the cpu to 76c?
 
thats not good then especially since your using water cooler. run prime95 and its probably going to hit 90c. worth investigating whats up with it or the cooler.
 
Agree I've been running a 3600 & 3900X with a Silverstone cooler that was a bit marginal for the 3900X except the case is large and well ventilated and I wasn't seeing above 65C in the worst case when gaming.

Unless you room is exceptionally warm I'd want to be under 70C especially using an AIO.

My i7 12700X is under 60C normally with a 280mm Kraken AIO. Even the RTX 3080 in that case was at 68C this morning playing Icarus in a 25C ambient room.
 
@MeatLoaf , you've also just changed to a RTX3080 and 4K monitor so were those 65c temps using your old GPU as well? Also is your H100x AIO new or something that you've had for a while?

Not only do you have a hotter running CPU but your new GPU is dumping much more hot air into your smallish 540 case. Hopefully you've got great airflow going through that case because you will need it now more than ever.

Just an aside, I've owned an H100 for several years. I don't like them and wouldn't recommend them as there are much better 240mm AIO (cooling per dB noise) coolers for less money. ;)
 
Yeah the lower temps were with the 3600 and the old 1070ti.

Airflow wise theres a couple of intakes at the front and and exit at the back. Also got the fans on the aio up top as exhaust as well so it could be taking hot air from the gpu over the radiator. Maybe I should turn the fans round so they draw cooler air in

A 3080 kicks out a lot of heat into the case so I wouldn't worry to much. I sometimes get higher CPU temps while gaming than when running prime when the GPU is idle.

If you want cooler CPU temps then just front mount the rad, this will raise the GPU a couple of C's though.

Yes the GPU will and can dump hot air into the case from the backplate pipes etc. so then the CPU will run hotter in games but lower just doing Prime 95 with an efficient cooler (my pc case is fairly small too and a little cramped)

Since I bought a 3070 in my case my CPU runs at 74 c max while gaming but only runs in the' 60s running Prime.

From my experience and knowledge your temps are totally fine and understandable,I don't think you'll get much lower unless you change cases I reckon or get super loud fans!!!. I have always personally aimed at ideally never to reach 80c on a CPU -if it does to improve airflow/cooling.

So..in theory your Prime 95 temps should be lower than when gaming.. are they?? :D



I have a dark rock cooler.

AMD say Zen 3 can run all the way up to 90C without an issue so you are 15C within spec. AMD CPUs just sort themselves out 1000 times a second I believe.

The warm air from the GPU is probably increasing overall case temps but its fine. Are you gaming 24/7? :) Modern CPUs will throttle before they reach dangerous temps.
 
I’ve recently bought a 5700x and am currently using it with a Wraith Stealth CPU cooler, I get CPU temps of 83C when running Cinebench or 3D Mark and I am not getting maximum performance out of the CPU with this cooler.

Am looking into getting a better cooler but it’s fine as it is albeit slower than it could be with a decent cooler, max working temp according to AMD is 90c so I’m 7c within that under load.

Not bad really for a crappy Wraith Stealth cooler.

Better cooler wont make it go faster since your already not at the throttle point to make it slow down.

I know but I’m not happy with the temps, they are within AMD specification but a bit too high for my liking and enabling PBO increased temps by 12c to 95c. I got higher Cinebench R23 results but I never let it finish because of the 95c

Maybe with new cooler I can enable PBO which will give me higher Cinebench R23 scores. New cooler I’m getting only £16.66 which is good value for money and has a TDP of 180W.
 
considering your using a H100 aio your temps are worse than those on air cooling. wont be surprised if the cooler you have is low on coolant/blockages/pump issues etc.
