Its just AMD CPU's that idle high right?

Hey guys,

As I was enquiring the other day regarding my GPU, it got me thinking on my temps on my 5900X..that when doing basic tasks, music, edge, steam, mail etc..im averaging around high 40's and low 50's degrees..and under "idle" its only dropping my cpu to low 40's..

Am I correct in saying that compared to Intel, the idle temps are bit higher?

reason i ask, is my temps are great under load (well, game load, not synthetic benchmarks) the temps are not much higher, not that they are dangerous or loud etc.. just was curious.

im only running the Wraith Prism cooler (because I love it) so mabye thats a small factor?

If you put a better cooler on it that will make a big difference. I’ve got a noctua D15s and mine idles about 30c. In Starfield it’s about 63c.

the thing is, in game it gives good temps (put a limit on the CPU) and average mid 60s degrees..and I love the WP cooler, I know its not the best but for its size does a fair job tbh..

I think a lot of it will be because of the cooler - i.e. it's a large lump of copper with a fan that blows downwards - it can carry a lot of heat away from the cpu package, but because of the downwards fan it doesn't get rid of that heat as efficiently as most tower coolers - resulting in a certain amount of heat just "soaking" in place

but even with the higher temps at "idle" that wouldn't damage the CPU in anyway would it?

What is your memory speed/ infinity fabric speed? I think if you are at 3800 or above the io power draw jumps up a fair bit and that doesn't clock down at idle so your temps will always be that bit higher.

memory speed not that high tbh mate. its 64gb kit at 3200MHz.

My7950X idles at ~35C, I'm using ECO 65W so that may drop’s it a bit, but the cooler (AF 360 AIO) fans are set low(~650rpm). For me, Increasing the RAM from 4800 to 5600 bumps the idle power draw up ~10W so that will have a small impact.

yeah, im using ECO 65W too, that brought my game temps right down (also helped my GPU), and i haven't really noticed much of a performance hit..

My 5800x3d with a noctua nh-d15 runs about 35-40c when idle and 60-75 depending on the game.

The above is inside a fractal r5 with is not the best case for air cooling.

Personally id download pbo2 and have a go at adjusting the power curves, knocked off 10c from my chip at load and 5c at idle.

thats something I might look at in the future, but overall, considering im using a "basic" cooler on a 12 core chip, the temps seem reasonable..

so will stick with it for now! cheers though!

well, i left my pc for 5-10 minutes..came back and my GPU + CPU were idling at around 35-37..so happy at that. Obviously jumps up when I fire up AMl, Edge, Steam etc..

But the biggest jump has been limiting the power from 100% to 85%. It still peaks around 70-72 but the fan speed has gone from peaking around 75-80% to around 65%.

So happy atm with things..

Need to use wall plug meter to get some proper figures.

Good shout. Never thought about that. Surely even with the GPU sitting around 300w , An 850w gold PSU is enough juice?
