[SOLVED] The temperature of my 10900x is too high.

[kyungminpower]

Hi,
I'm using 10900x on aorus x299x master and cooling it using Corsair Hydro 115i.

In bios, 64 degrees in Celcius.
In ubuntu, I measured the temperature using lm-sensors.

> 43 degrees in Celcius, idle, CPU usage almost zero.
> 98 degrees, CPU usage is around 95%

I don't think this is a normal situation.

Could anyone give me any advice to solve this weird situation?

First issue: you bought a 10900x

Just kidding, but a threadripper CPU probably would've been better, cause intel 'gaming' CPUs don't really give more than 4-5 frames extra per second

Yes, I'm already regretting that I bought a 10900X T.T
The only reason why I chose a 10900X over a 3900x was the number PCI lane.. but clock speed and the temperature are the real problems. The training speed using a 10900x is even slower than that of an 8700K which is my ex-CPU.

Actually no. You are somewhat right.

To find the power limit associated with our chip paired with the Gigabyte Aorus Z490 Master motherboard, we ran a few Prime95 tests with AVX enabled (small FFT). During those tests, we recorded up to 332W of power consumption when paired with either the Corsair H115i 280mm AIO watercooler or a Noctua NH-D15S air cooler. Yes, that's with the processor configured at stock settings. For perspective, our 18-core Core i9-10980XE drew 'only' 256W during an identical Prime95 test.

The H115i is a 280mm AIO, it's rated at @ 300w capability, so a 10900k under a stress load like Aida64 or P95 that doesn't have AVX disabled is going to push even the largest AIO's to their limits, Aircooling is all but eliminated as a cooling solution. The NH-D15S is a 250w+ cooler and stock usage after Tau, without AVX is still pushing 225w+.

With that cpu especially, recommended cooling would be full custom loop if planning on pushing it to limits with OC or high cpu usage like rendering, with a 280mm AIO as a minimum size for gaming standards, a 360mm would be preferable for its extra @ 50w of capacity.

That cpu is a Beast, if ever there was one, go Biggest or go home if you want to tame it, big won't cut it.

@Karadjgne
OP has the X series, not the mainstream model, but I reckon it doesn't change much.

Hah, oops. Totally missed that.

Intel Core i9-10900X Review | bit-tech.net

Intel's latest 10-core has received a hefty price cut, but is it worth the cash?

bit-tech.net

With full system totals, figure @ 100w for the pc, so cpu load will be @ 35w ish at idle, 280w ish at full load (accounting for 90% psu efficiency) , so still getting hot but not all that much headroom for temps even with a 280mm AIO.

Its not bad by any means, just a little overpriced

Thank you for all the comments
I just installed H115i Platinum then the temperature of my CPU stabilized between 30 (idle) - 70 (CPU Usage > 95%).
I didn't suspect my H115i was broken but now I need to admit it =,.=;

Those temps look good, some might not have much good to say about that cpu, when compared to its bigger brothers, but it is still a beast in its own right
