Please, Is this a serious mistake ? Possible cause problems in the future ?

My answer:


At some time in the past, your drives recorded air temperatures of 63, 62, and 60 degrees, respectively. The drives currently report temperatures of 27, 27 and 29 degrees. The attribute alarms at 55 degrees. (These values are calculated by subtracting the raw values in the VALUE, WORST and THRESH columns from 100.)

Unless you have some other temperature monitors in the server, or some other knowledge of the server’s environment, it’s not possible to say when this occurred or for how long.

There is probably no permanent damage to the drives, if the thermal events were of a short duration. But the drives are probably more likely to fail in future, especially if they become too hot again.
