Core Temp is giving me 30c to 40c when I'm surfing the web and around idle, I'm unsure if this is adequate because i have a dell case with one exhaust fan and poor cable management because of the size of the case. Should i be worried about this? Upon installation some of the pre-applied thermal paste was rubbed off (had to put it back in the box) so I'm a little concerned. Thanks for the help guys!
