None of the Dell computers or servers we use have fans pushing air in, all fans are either to cool hard drives, cool video processors, cool CPU's or to expell it from the case.

 

Pulling warm air out creates a low pressure zone inside the case allowing  all the small openings in the case to bring in cooling air and such openings can be designed to cool multiple components in multiple sites inside the case.

by nature of computer's case it would be less efficient (I would go into details, but easy to see the issue, if you have good 3D imagination of airflow); BTW, internal fans like used for video cards or any internal kind do create internal swirl airflow what is not  taking ambient air inside; perhaps pulling fan inside of power supply helping a little ... it's hard to describe... easy to see if you will fill the case by smoke as it's hapening during aerodynamic tests of jets, cars, rockets ...

Yeah, about cooling the DVR, I was wondering about something.

 

I have a USB fan and wanted to use an electrical outlet as it's power souce instead of the USB port in the DVR because I didn't want the DVR to work harder than it had to.

 

I found this AC to USB Adapter that's used to charge the battery in my Nikon digital camera and hooked it up to the fan and it works.

 

I don't know much about electronics.

 

My question is, is that safe?  It's not going to explode or cause a fire or anything like that will it?

Should not be a problem.  I would go the same route.
