Overheating with m5500 on a nVidia 8600m GT

do u have it propped up on a book or something to get good air flow also you might want to reapply thermal grease to the GPU...

Hello,

I'm currently using the 8600GS in my system and It's running great with a slight bit of modifying. I know the GT runs hotter but you may want to try and do what I did.

After you have installed the card place some arctic silver 5(recommended paste) then place a small COPPER plate(2cm x 2cm and 1mm thick on top of the paste to act as an extra heatsink. I then placed the original thermal pads on top of the copper heatsink and then re-install the heatsink and fan. I re-used the original heat pads but imagine I would get better drops if I used new pads.

Dont forget to re-connect the fan connection. Also dont forget to re-apply thermal paste to your processor(Very Important).

The only difficult part here is getting the "extra" copper plate as mentioned above.

Doing this reduced my temps by at least 10 degrees celcius. I also use a NoteBook cooler - The Zalman NC1000 - this reduces temps by another 5 or so degrees.

When I am not using 3d intensive programs or games I keep my card downclocked to the min clock settings and the temps are idle around 65 to 67 degrees celcius.

When I game I switch my card back to default clock speeds and the card maxes out at around 85 degrees celcius during heavy gaming which is normal for this card. This card is made to reach 100 degrees celcius. But you need to maintain the heat so that it does not affect other components inside the lappy.

Your card is taking stress because it is running constantly at high temps. Unfortunately these lappies were not designed for these cards so I would recommend downclocking when need be and then going to default when need be.

Definitely try the mod I have done and you will notice the difference AND get a cooler.

I've considered getting a new laptop but I really like my m5550i and these mods seem to work for me.

Good Luck!

No worries,

You should apply the paste only to the large square chip in the center of the card. The copper plate must be large enough to cover this "center chip".

I'm a Casino Manager so we have Casino Techs. I asked one of them for the copper sheet/plate and they sourced it for me.

I imagine most sheet metal suppliers will have copper sheets. Basically anything that is about 1mm thick.

You could also try hardware stores...

I am curious as well. Once the warranty runs out on my m5500 in April, I am thinking of upgrading the video card...
