Is it possible to connect the cooler in parallel with the power of the hard drive?

Question

Power Supply

The disk is heating up. I want to put a small cooler next to the disk, but there are no free connectors on the motherboard. But there is a free end with 15pin power. On alik there are adapters from 15pin to 3-4pin. Can you do that? What problems can there be?

Answer 1

Can.
In any case, it is connected in parallel, even if without an adapter.
It is simply paralleled on the power supply board or on the motherboard. The difference is not significant for such a small load as a fan.

Answer 2

Can. There will be no problems.

Answer 3

It is possible, but it is highly undesirable, since the cooler generates alternating current during operation, and the disks and everything in the computer are powered by direct current. current starts to swell
