First small project: Swap out the noisy fan!

The Watson W25-AM (25 Watt) power supply, is renowned for its jet engine antics, once you draw more than 500ma from it.
Enter the spare 80mm fan I had won many years back in a radio club raffle.

Gave it a good clean out while I was at it. It is much quieter now. I do need to get a modern silent fan for it. But this does me for now.
