New PC Temps

[Corey N Georgie]

I've got my new pc which has a Ryzen 7900x3d processor.

Idling the temps are around 62*c and gaming I've seen it hit 92*c.

I'm using an AIO with a 280mm radiator which should do the job, the system is happy even at those temps.

The max operating temperature is apparently 89C.

My 7950X idle temps are 45-52c depending on temp of the room. Always a bit higher in the summer obviously.

The limit I've hit was around 82c.

I don't take a lot of notice of the temps, so not sure what's good and what's bad.

When gaming I have now got into the habit of setting the fan/cooling (iCue) profile to max. Same with the GPU fans.

Idle temp is way to high and needs investigating I think. I would check the cooler. Is it offset? a lot of coolers for Ryzen go offset as it hits the die better

Gaming will hit the GPU harder than the CPU. To test the CPU you need to run something like Cinebench I am guessing it would thermal throttle

I'm sure when the Ryzen 7000 series launched it was found that they will run hotter and 90+ was fairly common when under full load. I have a 7700 with a Be Quiet! AIO. Can't say I have checked my temps but when gaming with newer games the fans do ramp up. AIO always at 100% but case fans and GPU are set to fan curves optimised by the Armoury Crate software.

After searching, the 7900x3D has a max temp of 89°C and the 7900x is 95°C. Seems the x3D chips have a lower max temp. Is your cooler seated correctly and enough thermal paste applied?

Our daughter's new PC had a heatsink that all her friends considered far too small for the processor. So she opted for a better one, but still gets rather high CPU temps. She had to stop gaming the other day as her room hit 38c with the doors and windows wide open.

I mean that's partly a good thing as the PC is expelling all the heat. It's good in winter though for keeping the room warm. Newer hardware does run hotter as it is more powerful.

The heating in her room rarely switches on during the colder months. But what that saves in gas is turned into a higher electricity bill. The lad's much smaller B̷o̷x̷ ̷R̷o̷o̷m̷ third bedroom is like an oven all year round.

I must admit I do game less in the summer due to the heat. Sometimes I run them at a lower res so it doesn't generate as much heat. In the winter I do notice it a lot more, play Cyberpunk for a couple of hours and the room is toasty. The heat they now generate is a bit of problem.

I have a relatively high end PC and when it is running under high load gaming it still only uses 450 watts from the plug. Factor in another 50 or 60 watts for the screen you are still only slightly over 500 watts which at current rates is what 12p per hour ( Octopus rate ) Normal computing it is only pulling around 60 watts from the plug plus the screens

I would bet the OPs system though will throttle quite considerably under full CPU only load. I think there is something wrong with the cooling. Either not enough air drawn into the case or poor mount or poor thermal paste spread or I would not be surprised if it is not an offset mount and really should be for that CPU

check the heatsink and it's position. with those temps, I'd be tempted to get the heatsink off and check the peel-off plastic sheet isn't still covering the base plate of it.

Benchmarking temps hit 92*c max and system is stable so I'm happy.

As long as system is stable I'm happy.

[Stephen]

Was it a prebiilt one or did you buy parts and put it together?

Temps should by a little lower than that.

[Corey N Georgie]

I bought the parts and had it built for me.

[Stephen]

I've had my system on all morning running benchmarks and Hogwarts Legacy and haven't been able to get my CPU temp above 73°C, so there may well be something wrong with the AIO or how it's been seated. Perhaps the plastic that's usually underneath the heasink was not removed.

My idling temp sits around 30°C, so 60 idle temp is really high.
