Question WD sn850x normal temps?

[Sal1ty05]

I have three WD sn850x m.2
My 2tb for the os temp is at 40 most the time and hits 54c on crystal disk stress test.
Both my 1tb run around the same temp 45-48c. These two are next to each other under the heatsink.

Are these temps good?

Excellent. Doesn't look like you'd even need the heatsinks.

NVMe tends to run hotter than standard SSDs.

I came from the regular ssds so I wasn't sure on the m.2 versions.

To give you an idea for comparison

Right now in my room; 81 degrees F; 27 C; idling temps:

2 case fans running at 500 rpm

WD Green 3.0 TB spinning hard drive; 37

Intel 660p NVMe data drive; 40

WD SN 770 NVMe boot drive; 42

Nothing with heatsinks.

I used to have a standard SSD for a boot drive; that tended to be 3 or 4 degrees cooler than NVMe.

Temps are fine.

I see more posts about temps for CPU/SSD, 99.99% of all posts your fine.

Each part will have a rating by the MANF.

If look at the WD spec sheet it says 0 to 85C. Your temp falls in that measurement so your good to go!

my 850X 4TB is running at 36C idle in windows.

There are 2 sensors, the memory and the controller.
Everyone sees the memory. Use hwinfo to see both.

Controller temp is typically higher.

HWInfo shows 3 temps on my WD NVMe drive and there is often a 20 degree range among the 3.

I don't know, but I'd guess the throttling temp is based on the highest temp found on the drive?

I recently ran a Crystal benchmark and the 3 max temps realized were 52, 73, and 47; without a heatsink.
