acer aspire 5584 heatsink

on this 2 heatsink above, different would be the heatpipe near the end. but the end part heatsink on my laptop mainboard below is the nvidia graphics.

so would the "missing" heatpipe causes big difference in temperature? (this 2 heatsink is stated on the web that it is compatible for my model)
when i was playing game, graphics temp could hit 80 to 90. i'm very scare tat the graphics would up lorry again. current heatsink is the 1st pic which heatpipe is extend to the end.

i hav it disassembled(thanks to Andy for the youtube vid).
this is the heatsink after i hav send it for repair.(i knw they change the whole board). but there hav several layer of copper pad.


now wat shld i do to bring down the temp? i hav jus apply thermal grease to it. but the temp no difference.

 

Was there a thermal pad, or just thermal paste on the GPU side of the heatsink or the nvidia GPU itself ?

If there was a thermal pad, don't touch it.

If there was thermal paste, try cleaning it off the heatsink and GPU, and apply a good thermal paste like AS-5, or any other good thermal paste you know of. You can do the same for the CPU as well if you want to.

I hope you have some experience doing such stuff.

 

yup..i hav experience in doing such stuff.

when i remove the heatsink, the cpu side is thermal paste. center side was the thick thermal pad. at the end was also using thermal paste too. but due to the gap, it uses many layer of copper to stick to it.

here the pic:


after than i decided to switch the thick thermal pad n layers of copper. so the thick thermal pad is at the gpu side.

for the layers of copper, i put thermal paste on both side of it. so hopefully the chipset wont get too hot.

btw is there a sensor at the chipset? Everest dont hav. but speedfan show additional "temp1". inside configure, it shows "ACPI" chip. not sure is it the temp of the chipset which lies in the center of heatsink.

now searched on ebay for thick thermal pad. not sure 2mm is enough or not.

 

Don't switch the thermal pad and copper sheets. The copper sheets are much better for cooling the GPU. If you want, you can buy some Cu sheets and make your own Cu pad, apply AS-5 over it and mount it over the GPU-side of the heatsink.

The chipset thermal pad is pretty crappy, and I doubt it'll keep the GPU cool. The chipset has a TDP of less than 10W, whereas the GPU has a very high TDP compared to the chipset.

There is a Copper Mod thread in the Dell Section for the M1330 (soldered GPU). Check that out....

I believe their is only one sensor (THRM) and it can be monitored using HWMonitor. This sensor most probably controls the Fan RPM.

 

i have switch over the thick thermal pad to the gpu side, n guess wat? the temp got lower alot! by around 10.

actually i was thinkin tat the several layers of copper sheets, which tat causes the increase in temp, so the contact in between the gpu n heatsink got some air space.

previously after i get back my laptop after repair, when i play game, the fan runs at full speed. but now after the decrease in gpu temp, the fan stil runs at normal speed.

i wil explore the thread n try out the program. thks for tat.
