hi, thank you for your quick reply
my CPU is : Core 2 Quad Q6400 2,13 GHz (or Core 2 Quad Q6600 2,4 GHz, not sure because I can't use my PC without a GPU), 4GB ram
someone suggested me to overclock CPU to 2.8 or 3, this could get my PC hotter even when CPU is at normal load or idle?
do you think my UPS enermax liberty 620, is ok?
thanks again
