In Samsung Magician, the first drive temp is reported as the SSD temp, however in hwinfo it shows 3 readings the third being the nvme controller.

Any idea why it is so high? Im using a B650E PG Riptide motherboard and the SSD even has a heatsink over it (both DRAM are touching the heatsink).

Appears quite warm.

I was looking at my 990 Pro nvme drive temps in HWiNFO:

This drive is under the Frozr heatshield on the motherboard as well.

The controller chip and the RAM chip(s) are sometimes at slightly different heights. The controller chip is in far greater need of good cooling than the RAM. I've seen reports saying M.2 RAM benefits from being run quite warm (mid fifties/sixties Celcius). At 98C, you've hit the controller's throttle point.

It's difficult to see under the label (which might be made of Copper foil to act as a heatsink) but I think the controller chip which needs the most cooling is on the far right hand side, next to the gold-plated contacts. Don't worry too much about the RAM. Also, it's not recommended to remove the manufacturer's label. They might not honour an RMA if it's obviously been "tampered" with.

Problem is your controller probably isnt making good contact with the heatsink. I had this issue with one of my SN770s on my current MSI board.

Its that garbage heasink mounting system that they use that doesnt take into account that not all SSDs are the same height. NAND chips often sit a a bit higher than the controller chip. If you have a spare 1 or 2mm thermal pad. cut it to size and place it on the controller before screwing it down. Keep the stock pad on there. It will all crush down and still drop the temps by 20-30'c

If thermal pads are too expensive. Consider getting one of the 3rd party chinesium heatsinks off amazon that can be bought for around $6. Those come with thermal pads and will cool a lot better than the heasink that comes with the MB.


::EDIT::

If I have to put it into context....

This part here (in the red box) is sitting a little too high and that stops the heatsink from crushing the thermal pad down onto the controller.

::EDIT II::

If you want even more context of the context. May I refer you to my before and after results - Arctic pads are pretty good but the MB heatsinks themselves arent super awesome due to the lack of surface area for really good cooling. Still more than happy with the results and I used TP-3 pads on ALL the SSDs so its definitely worth buying a pack or two. Even if you dont use all of them. You could use them on other stuff like GPUs or VRMs on older MBs.

Look at your case cooling too. Make sure you have a good "flow" of air through the case and across the drive. Ensure good, tidy cable management to minimizing impacting that flow. And make sure the interior is clean of heat trapping dust.
 
Do you get any hardware errors in event log? I had similar issue with my system. Turned out it was the faulty PSU. My system used to hang randomly though, unlike yours.

I looks to me that Temps 1+3 is the same sensor of storage chips and temp 2 is the controller which is always warmer than the rest drive.

See both NVMe drives below (980Pro + 970Pro)
980 is OS drive next to CPU socket and 970 is buried under the 3.5 slot GPU

That high temp is a strong indication that the heatsink is not properly seated. To thin a thermal pad. Or for some reason there is a heat trap at that spot. If you carefully remove the heatsink there should be an impression in the thermal pad of every chip it is properly seated on.

Unless the sticker is marked warranty void if removed, you can remove it. I have not seen any marked that way in the last few years either. So seems the manufacturers have realised people have to remove them to properly fit a heatsink in many cases.
A bendy sticker like in that picture is also very unlikely to have any worthwhile heat spreading characteristics. I would 100% remove it to mount a heatsink. If you want to keep the sticker put it on the backside of the ssd for easy access to S/N and stuff.
