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,
