First, I want to thank shifty22123 and all the posters for the great info about the p-7805u FX series laptop.
Especially the dis-assembly guide. The detailed instructions & photos were fantastic.
I was concerned because HD temps were hovering @ 45C & the MB temps @ 52C running @ idle after 2 hours with room temp @ 70F. Under load the primary HD would reach 53C, too close to max for piece of mind. This lappy is stock.
I just completed the first tear down & re-assembly of the laptop. The interior was fairly clean, which I found quite surprising for a 5 yr. old machine.
The heatsink vanes were another story. Even though I blew them out a week ago, both were partially clogged ( 1/4 on the CPU & 1/3 on the GPU) with large dust bunnies in the corners. Now everything is spotless.
CPU & HD's are now 10 degrees cooler, MB is 5 degrees cooler, GPU only runs 2 degrees cooler, all at idle. The fan cycles less frequently. Ambient air temp is 70 to 74F.
These are the idle temps after 2 hours: under load using Arma2:
GPU = 47C GPU = 64C
HD1 = 40C HD1 = 42C
HD2 = 36C HD2 = 38C
MB1 = 39C MB1 = 58C
MB2 = 39C MB2 = 58C
Core0 = 32C Core0 = 47C
Core1 = 32C Core1 = 47C
I have a couple of questions about observations during the dis-assembly & about the MB temps.
When I took off the CPU heatsink, I noticed on the northbridge chip that there wasn't any thermal paste. Just a spongy square piece of material. I suppose this is the TIM pad referred to in the guide. It wasn't damaged during the dis-assembly.
The center of the material had a squarish depression
in it. Is this normal?
This would appear to be counter-productive to proper heat dissipation.
As to the MB temps, what is normal & what is max? I could not find any info about them.
Also where are the sensors located in the MB?
Thanks for all your assistance...
