Question C: Drive Overheating

[koberulz]

Got an alert from CrystalDiskInfo earlier today to say my C: drive had hit 62°. On the "Performance" tab of Task Manager, its Active Time was basically stuck at 100%. I had a look at I/O Read/Write on the details tab, Waterfox was highest and had actually been quite sluggish, so I killed it. C:'s Active Time crashed down to around 5-10% for the most part, with intermittent spikes to 100% still occurring.

Came back later, reopened Waterfox, did some browsing, and C: has hit 61°.

The one common factor is VidCoder. Both times, I was running a tonemap encoding of some iPhone HDR 4K video into SDR 4K. In between, I ran a tonemap encode of a UHD-sourced video into SDR 1080p, which the C: drive was just fine with, even with Waterfox still open.

None of the video, though, is or was stored on C:. The UHD-sourced video was stored on my NAS, and the iPhone-sourced video was stored on D:. D: remains at 45°. So...I'm confused. There shouldn't be a huge activity spike on C:, and I have no idea how to figure out what's causing it - and even if there is one assumes the drive should still be capable of remaining cool enough. It's warm in here but not exactly hot, I think it was around 25° outside today and in a month or two it'll be hitting 40° on the regular so if it's not coping now...

If your C: drive is an M.2 NVMe, then 61°C under heavy load is not unusual. These drives tend to throttle around 80° to 90°C.

If on the other hand it's a spinning hard disk, it's getting too hot. I get anxious when my hard disks exceed 51°C.

It's an NVMe, yeah. So I should tweak the threshold in CDI?

Either way, though, it's never spiked above 60° before today, and it doesn't make sense that it's "under heavy load" given all my data is kept on other disks. So I'd like to figure out what's using all that I/O bandwidth, especially since it seems to be slowing my machine to a crawl.

That really depends on the drive gen. PCie 3.0, way to high. PCie 4.0 still high. PCie 5.0 yeah, 61 is about normal.

Please list your full PC specs, and the drive make and model obviously
