My current setup runs a bit too hot for my liking. My Q6600 is at 2.60 GHz and is already idling at 40 C and reaching 60 C under load. My CPU cooler is a Zalman CNPS9700, and it's a fairly decent cooler so I am sure that the problem is with my case. The case is an Antec Sonata II, and it has terrible ventilation. With the stock rear fan installed and one other (there is only one other place to mount one, and it only lowered the MB temp by a degree or so) the temperature drops down by about 5 C when I remove the side panel. I am thinking of getting an Antec Nine Hundred case, because of all of its fans. I don't care how loud it is, if it was as loud as hair dryer I wouldn't care. Is it typical for a mildly overclocked Q6600 to run that hot, and how much would I benefit from a really well ventilated case?
