這是一個省錢 美觀 又實惠的東西!!為何省? :省在電費!!用電量是兩個LED造型風扇在花費LED造型風扇解析:12V 0.11A電費計算 :  如果1度電為3元的話,一年24H讓它持續做功 話費為.... (如下)12V X 0.11A = 1.32W1.32W X 2(風扇X2) = 2.64W (這是耗電量)2.64W X 24(一天24小時) X 365(天數) = 23126.4W (這是一年的耗電量)23126.4W X 3 (元) ÷ 1000 (這是一度電的算法!!) = 69.3792 (這就是LED造型風扇一年所花的電費 約70元!! )為何美觀? :因為外面買不到 , 物以稀為貴XD為何實惠? :因為材料隨處可得!!DIY自製完成會很有成就感!! 電源:使用電腦的power來供應
