Just a very dumb question - although I'm not really knowledgeable on this.

Hi... I just have a very dumb "non-electronic-guy" question to help me do up a cooling fan for an indoor hydroponic system: If I have an adaptor with a power supply of 12V, 2amps., will I be able to or will it even be safe to hook up three (3) computer cooling fans (on to the same adaptor) with this rating: DC 12V,0.30A? For any question on why am I asking this, well, it's basically just to save on the number of power points I'd need to plug in three basic cooling fans. This is just to basically blow air to the plants. I'd really appreciate anyone's help on this. Much thanks in advance.

The 3 fans must be connected in parallel--you probably knew this. Each fan requires 0.3 amp so total requirement is 0.9 amp. Your power supply is rated 2 amp so this is plenty for the 3 fans.
