xps m1330 gpu problems/observations

Thread Starter 
so dell just sent one of their service techs out to replace the motherboard on my sister's xps m1330

i noticed that the a single heat pipe/heat sink/fan is the main form of cooling for the entire notebook. I must commend dell on their design and engineering of this laptop. For something so compact they did a great job keeping the temps on the CPU/Chipset down. with HWMonitor i have observer the average temps under full power (45/49/62) from min/avg/max. My Toshiba Satellite on the othe hand runs about mid 50s to upper 60s.

I couldn't help but notice that the heatpipe doesn't connects to the chipset and gpu directly, but is sandwiched by a silver looking piece of aluminum and a blue thermal sponge type substance.

Could the sharing of the cooling system or the usage of 2 other materials be the reason why so many dell Nvidia powered m1330s take a dive?

The service tech did also say that of the m1330s he services, the most common ones that require servicing are the Nvidia powered ones and that the Intel integrated graphics rarely ever require replacement.

Or it could be that the nvidia 8400M GS is one of the un named GPU's that have a high failure rate?

The Vostro 1310 I have is pretty much the same....has a puny little heatpipe cooling all three components,which works well when not being stressed.....but as soon as you play a game on it,struggles to keep component temps[particularly the GPU] down.

When I first got mine,playing a game resulted in GPU temps of 91 degC,which is pretty high for a low end GPU......pulled it apart [which is extremely easy like the small XPS's]and the pad on the GPU was only touching half the core.......a quick bend of the heatpipe assy and some AS5 resulted in 85degC max temp.
Another thing I've noticed is that even with these high temps,the air being blown out of the radiator is not that hot,which indicates to me that the heatsink/pipe/fan assy is not that efficient at getting rid of the heat anyway.....so maybe your right.

Are you referring to the below info? **warning info based on the inquirer**

About to get my 1330 and don't want to deal with graphics problems now or in the near future.

Mmm....I wonder if this is getting blown out of proportion.....can't say I've seen a huge amount of reported failures here or on NBR forums,and there would be a huge amount of 84/8600's in worldwide circulation,you'd think.

Still,makes me glad I have a dell NBD warranty

Yes, most of the reviews were stellar and I am still excited about my new system, but you can bet I am going to stress the hell out of it to see if there are problems. ATITool still good for beating the hell out of a vid card?

Seems there is a new BIOS (A12) out July 9 that mentions thermal performance:

Fixes/Enhancements
------------------
1. Added enhancement for thermal control.
2. Update GM965 Graphics VBIOS from 1466 to 1588.
3. Update Intel CPU family name.

Lol...Crysis is pretty good at it too

Congrats on your new purchase....I'm new to the 13.3 inch size and must say its grown on me a lot......the XPS would have been much nicer,but the vostro was a lot cheaper and was bought as a temp fill in until montevina models come and it gets handed down.

if you are doing day to day activities without stressing out the gpu you are going to notice a thing, but apparently if you push it enough - it will crack.

my sister basically uses her xps as a email/research/word processing box but i recently gave her this shitty little game called ROCKET MANIA and it apparently stressed out her 8400m gs enough.

BTW this is her 3rd motherboard/gpu.

If there is anything that's going to kill an IC its heat and its pretty disheartening to know that Nvidia is aware of the failure rate and flaw of the 84/86 series and aren't doing anything but trying to put a band aid on a pretty nasty situation.
