well it could be the cpu fan: by demanding that extra effort from the processor, in anticipation of summer arriving and the high temperatures usually found in my area... i should opt for another one perhaps more suitable: what alternative would you recommend (remember that it's a micro-ATX system in terms of dimensions) to cool the processor??? the noctua nhc-14 could be good for example because of its horizontal position, right, although ultimately it's not far from the general dimensions of the typical "tower" fan...
thanks for the attention, Obione!
