I am a scientist by training (Eckerd College, BSc; Caltech, Ph.D.). I worked for 27 years as a Chemist in the Pharmaceutical Industry developing processes to manufacture medicines for human and animal health. I now spend my time as a photographer and world traveler. My interests include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.

Passive Computer Processor Cooler: Synology DS3615xs

In order to add more memory to the Synology DS3615xs  high capacity data storage array, I needed to open the system. Following the online directions, I finally was able to open the box — difficult as there were some wires and connections that were tight and hard to get at. I was amazed at the size of the passive cooler on the processor chip. I am assuming the copper pipes have some type of heat conductive fluid to help transfer the heat away from the processor.
