Hello! I've purchased the following just to give you an idea
:Asus z87-A mobo
RM750 Gold Corsair PSU
Asus CUII GTX 780
Intel i5 4670k

My idle temperature is always around 50-54 Celcius.. is that normal? I'm using the stock cooler since i've been told it was alright if i was not overclocking.. well such high temperature will reduce total life span by a lot, am i right? There was no thermal gel provided, only the stock cooler, should I get another CPU fan if i want this CPU to last ?
