How hot can a normal HDD hard drive (laptop) maximally be (I think the fan has failed!) 💽🔥?

I think the fan of the HDD hard drive here in the laptop (older model) has failed. I measured the hard disk temperature with https://www.chip.de/...78794.html and so far was always so when booting the laptop at the beginning still relaxed 30 ° C and then went up to a maximum of 43 ° C high v.a. On hot days, but the fan has always been very loud and clicked when it started! There was & is probably too much dust in it?
But now you can hear no more noise from the fan and the temperature was recently after some time up to dangerous 52 or 53 ° C high and then the temperature display in CrystalDiskInfo then yellow what "caution" means, so too hot for the plate! 💽🔥 I have to assume that the fan has stopped working because you do not hear it anymore (too much dust is not spinning anymore?)

From which temperature is it really dangerous for the hard drive and how could one such a laptop fan (I think he is on the hard drive or next to it?) Clean or is it something else?

With fans, dust can accumulate - sometimes you can bring it back with a vacuum cleaner, by reversing the air flow, but: This can break some, because the fan is the generator! So do not do it yourself without any idea.

When it comes to you, moist (never wet) cotton swabs help. Otherwise: ask a pro before the damage gets bigger. Maybe a friend knows his stuff.

Of course, normal hard drives are already warm, because of the moving parts. There are several rotating discs. There are different speeds, in normal client (PC, laptop) are usually 5400 or 7200 revolutions usual. But there are also 10,000 and 15,000 revolutions. This depends on the hard disk temperature that ChrystalDiskInfo gives you.

Usually you do not cool the hard drives with a fan.

Normally you cool with a cooler, the CPU and the graphics card. So, if the fan is not working, you should fix it as soon as possible - a CPU likes to die from heat death if it is not cooled sufficiently.

HDD hard drives wear out faster the hotter they get. 40 degrees are still very comfortable for HDDs, but 50 degrees are pretty much, and 60 degrees would be a disaster…

But how can you repair the fan, because I can't help you with the laptop, unfortunately. Maybe you bring that to a repair, or are you satisfied with the increased temperatures? At 50 degrees, a good HDD can still last 4-5 years…

In any case, I would back up important data regularly when the HDD gets hot.
