Major laptop tune-up --- HELP.

post #1 of 2
Thread Starter 
Hello fellow overclockers,

I own a DV7-4060US with an AMD Phenom II N830 @ 2.1Ghz, Radeon 5650m 1GB (equivalent of a 4650/70), 4GB RAM and a 500GB 7200rpm HDD. My main issue is the temperatures. I'm sitting outside at 6:43AM and the ambient temperature is around 75F.. I'm at 66C on the CPU using Power Saver. Max temps are 89C on the CPU and 85C on the GPU, but the thing that ticks me off the most is that I used to idle at 45C on both CPU/GPU and I'd max out at 65C.


So, I plan on opening my laptop up, removing whatever gunk sits in the heatsinks and reapplying the tim as well as upgrading my cooling in every single way. I also have a Rosewill aluminum cooling pad and it used to drop my temps by 3-5C but now it does nothing. How do I go about doing this?


P.S.
I own a dremel. As long as it looks good I'm more than willing to dig a few more holes for cooling.

I suggest to begin with undervolting the processor, all my AMD laptop CPUs have been very cooperative with this procedure. As to what to use I haven't had your CPU but so far K10Stats worked for every K10-based CPU I had so it may work for you. RMClock is more user-firendly but not compatible with some types of processors like my Turion RM-70 - maybe it'll work for you. By undervolting you can win as much as 10°C full load. You can also modify at which % CPU load it ramps up or down to the next speed bin (P-state) - so a neat trick to create a profile so that in scorching-hot days you'd use it to limit the top speed & voltage to a lower maximum; this way you could even limit the CPU to its lowest speed for web browsing which would drop its max temp even more.

About opening the laptop, you should be able to find a guide on how to do it step by step, google DV7 repair manual or something like that. The basics are simple - unplug, remove battery and then start removing all the 30+ screws until you can remove the back cover and access the cooling system and motherboard.

...I would really like to know if one can modify the Vcore of the GPU, I haven't found a way (yet).
