SSD Throttling

If SSD throttling is to reduce the temp then why does my 970 Evo Plus NAND temp reach 85-90C and controller temp sometimes approaches 100. I thought throttling was to reduce temp.

Is it throttling? Maybe it's failing to do so?

When I tested an M.2 SATA SSD in free air it throttled hard at 70°C. I think it also slowed down from 60°. This was a while ago though, I'm sure general developments and NVMe specific changes have both had an impact.

Last I checked some ssd's can run pretty hot before they throttle but I've never seen any of my drives hit that sort of temp.

There's a lot of questions though...is the temp actually accurate, is it even trying to throttle, does it have any air flow to get rid of the heat, is it under something like your gpu which adds heat to it?

My sata ssd's are currently running around 26c, my OS Seagate 530 with heatsink is 30c and my second 530 with heatsink is running at 20c... all while idle and temps from hwmonitor. The second 530 sits under my gpu.... but I'm guessing the fans at bottom of case are cooling that more than the one above the gpu.

It’ll start throttling once it reaches that high temp, but it’ll only throttle enough so as not to go any higher, not necessarily to bring it down. If you keep using it, it’ll stay high temp, but throttled slightly.

What are you using to read the temps, those seem exceptionally high, my 980 only gets to 60c when being hammered and that's with a 3090 in front of it.

Looking at their motherboard it actually looks right, the m.2 slots is directly behind the GPU (the slot is right below the PCIe slot) and there's no heatsink, while the Tomahawk's m.2 slot is above the PCIe slot and does have a heatsink. So basically their m.2 is starved of any form of cooling.

It throttles so that its still usable and not dead
