It was long ago. I repaired one computer, which after half an hour of work hanged and did not respond to anything. Diagnosis showed that the hard disk overheated and ceased to react to external stimuli. Well, I change the disk, it remains to rewrite the information from the old one. There were some clever specialized programs on it, for reinstallation of which it was necessary to contact the developer, no contacts, and so on. So I decided to just remove the image of the entire disk. Do you remember half an hour? I need to write one and a half...
The problem was solved in this way - the old disk on the wires was pulled out of the body of the system unit, and a fan was attached to it on two washing rubber and two money rubber, which was also removed from the body. On top was a table lamp (off), with which a polyethylene bag with ice was hanging on the rope, which was able to stack in the freezer. And the process went! The ice gradually melted, it had to be replaced a few times with a new one, along with a bag. Condensate on the bag did not have time to form. The bag was quite intense.
Such designs allowed the disk to work out the required time without failure.
