Same thing here in an i180. There's the quiet hum of the pumps and the main fan, but then also a rattle that seems to come mostly from the right side. I'm wondering if it's the extra fan on the graphics card. It sounds a lot like a hard drive working, but it's not that - I've got the HDD totally offline in the video below: [ame]https://youtu.be/7l7aSD5oIIc[/ame] In reality you can hear the rattle from further away than the video implies - it's fairly noticeable in a quiet room. In the video you can hear the rattle above the hum once I move the camera around to the right, around 10 seconds in. A little bit unfortunate as I was hoping to use this PC in a room where I also occasionally record music, and it's louder than my old air-cooled PC. Idle volume hovers around 40dBA from the distance shown:

I've now spoken to Corsair via their support and they've confirmed these temps are normal for this build.

Thanks yeah, usually thermal paste is the first thing I'd try as well. But since there's a temp sensor on the actual cooling system in this case and it's also showing much the same temp, it makes me feel like the thermal connection must be OK and either the CPU is just extra hot, or the cooling system itself isn't doing so well. Maybe that's an incorrect assumption though. I'm also hesitant to mess with this system at all considering the cost; if something goes wrong I'd like the have the warranty intact.

I recently received a Corsair One Pro i180 with the i9-9920X CPU and RTX 2080 Ti. In a room that's around 18°C, the graphics card idles in the sort of range I'd expect - around 32°C - but the CPU idles at around 55°C (top fan always running, but pretty quiet), gets to high 70s under ~20% load (fan still pretty quiet), and reaches up to 90°C under full load (fan ramped up a lot to cover it). The "CPU coolant" temp value likewise generally hovers around 20°C hotter at idle than "GPU coolant" is. Is that expected for this CPU in this machine? Seems a bit high to me. Since the cooling system's getting hot as well as the actual CPU it doesn't seem so much like an issue of heat not getting out to the radiator, more like the CPU just runs super hot - and certainly it heats the room it's in, even at idle. This Tom's Hardware review seems to have the same model maxing out under load at 55°C, but there's a typo so I'm going off the °F conversion and I don't totally trust it. If true though, that's 35°C below where mine tops out. I've attached a couple of screenshots at idle temps.
