Quote from Trader13:
People who understand computer hardware reliability factors do. That's why computer data centers are thoughtfully designed to ensure proper cooling and air flow. Just Google "intel i7 high temperature issues" to learn more.
Mobile parts have minimal heat issues compared to non-mobile parts. If a laptop manufacturer can't adequately cool a 45w mobile processor they're the ones that suck, not the CPU.
I said to get a slower processor to avoid the thermal risk with the i7. I would go for the i7 on a desktop or server chassis with better cooling, but laptops are not as well ventilated.
A Macbook Pro with a 2820M barely gets warm. Same deal with a Lenovo T520 and W520.
