Hi, in 2 weeks time a friend is giving me a Latitude E6440 BTX with the following specs: AMD Radeon HD 8690M Graphics 2 GB GDDR5 Windows 7 Professional (64Bit) 8X DVD+/-RW Drive 180Gb SSD 8Gb DDR3 Dual Channel 4th gen Intel(R) Core(TM) i5-4300M 14.0 inch HD+(1600x900) Anti-G lare LED-backlit Starting September I'll be using this E6440 as my laptop for school so I need it to have the longest battery life possible and as quiet as possible. I've read through this thread + others and it seems that the E6640 suffers from loud fan noise due to incorrect CPU throttling and inefficient fan management. So I plan to undertake the following; 1. Install a utility to undervolt the CPU (XTU? ThrottleStop?) 2. Install a utility to lower fan speed (SpeedFan?) 3. clean the HSFs for the CPU and GPU 4. replace the thermal paste between the he HSFs for the CPU and GPU (90° alcohol + Arctic Silver 5?) Do you think that these are the best and simplest solutions? If not, why? Many thanks,
