Question Concerning fan wattage

Hey everyone ,

I was wondering if anyone knew how many watts are needed to power a 120mm fan. I am thinking about getting a solar panal to power this.

My general idea is to have a fun running during the daylight hours to keep the air going in and out of the case. I think this should at least help with cooling as long as the air keeps circulating throughout the day.

Depends on the fan. Assuming these are representative:

as little as 3.6W and as much as 6.8W depending on airflow required. Possibly more.

Look on the center of the fan. On one of the stickers it should give you the voltage and current it needs.

We've discussed that idea some here:

Will you have air cominging in and out of the car too? Will your computer be on during the day?
