So, for those who may or may not know, my current machine is as follows Lenovo IdeaPad Y570 CPU: Intel Core i7 2670QM 2.2 GHz to 3.1 GHz (Turbo Boost 2.0) GPU: nVidia GeForce GT555M 1 GB GDDR RAM RAM: 8 GB DDR3 SDRAM PC 10600 OS: Windows 7 Home 64-bit HDD - 500 GB Now, we all know that laptop CPUs will most definitely run hotter than their desktop counterparts. I should also note that while this machine isn't super high-end, I've no issue running GPU/CPU intensive games such as Splinter Cell Conviction and Skyrim at very nice speeds at high settings (along with Dolphin and PCSX2). But there is one thing that I'm somewhat perturbed by, being overly paranoid about having to check the CPU temperature every ten seconds (not really, but very frequently). What are normal temps for the Core i7 2670QM while using something simple like Chrome? Or when it's at idle/low CPU usage? If dust is an issue, what's the most efficacious way of removing the dust without taking every piece of hardware out? Am I being too paranoid about the temps being too high or is it normal to be this wary? I have the program Core Temp and I have seen the CPU almost reach 80 Celsius/176 Fahrenheit under heavy load, and that alone frightens the s**t outta me. I have a laptop cooler, and I make sure there is sufficient airflow underneath the system (it's at an angle), so I want to make sure I'm doing it right. Any pointers?
