[Solved] Wondering about Intel Quad heat

I recently built a new computer for the first time in quite a while (probably about 8+ years), and installing Core Temp I wondered whether my computer was 'normal' as far as core temps go.

My CPU is an Intel Core 2 Quad Q8800, fan is stock

Core Temp reports the cores are idling at 44, 44, 42, 42 degrees Celsius respectively, during load they seem to be somewhere just above 50 degrees Celsius (I don't have an exact figure, been meaning to start logging while playing a game or somesuch and keep putting it off...) Does this seem about right? I've heard that multicores run hotter than single core CPUs in general.

If anyone has recommendations for after-market fans or other cooling solutions I'd be interested in hearing them... My case is the Antec Three Hundred, and I was thinking about purchasing optional case fans as well...

those sound like reawsonable temps

Ok, it looks like the highest temps I've gotten for each core while running a game are:

58°, 57°, 53°, 56°

Out of curiosity, when should I start getting worried? Somewhere in the mid-60s?

Can't give you specifics for your CPU, but as a point of reference the Core i7 920 will run in "turbo boost" mode (ie, at 2.8GHz instead of 2.667GHz) until the temperature on the heat spreader reaches 69 degrees - then it drops back to the "normal" clock frequency. So I'd guess that mid 60's is certainly nothing to worry about, as long as it's a stable temperature.
