A fan next 2 it might not b a problem but be carefull cause the fan might 2 flushing/ pushing dust into the circuits of yer mixer, thus making it acumulate on the board n circuits which eventually will create overheating probs... and that might catch on fire!!

Use the fan carefully!! or use 1 that pulls the heat fromn the inside of the mixer 2 the out side (that will work wonders)! :)
