Dell XPS M1330 - nVidia GeForce 8400M GS - Copper Mod - Step by Step Guide

Dell XPS M1330 Notebook with nVidia GeForce 8400M GS GPU has an inadequate Thermal Cooling Assembly. It uses a Thermal Cooling Pad between the GPU and the GPU Thermal Cooling Assembly instead of a direct contact between the two with a Thermal Compound. This leads to overheating the GPU and damaging it along with other components. The solution is to replace the existing Thermal Cooling Pad with a Copper Sheet and a Thermal Compound.

Note: This Copper Mod does not solve problems arising from a weak die/packaging material set in certain versions of GPU. Their failure appears related to the combination of the interaction between the chip material set and the system design. The combination of limited thermal management and frequent power cycling is particularly challenging for the GPU. Dell is offering a 12 Month Limited Warranty Enhancement specific to this issue. However, this Copper Mod might help delay the failure by improving the thermal management.

Materials:

01. Copper Sheet. Recommended: Gauge 16 & Grade C106 - 14x14x1.5mm.

Frequently Asked Questions:

01. How about using an Acetone based Nail Enamel/Polish Remover for cleaning the Thermal Compound?
A: Acetone based Nail Enamel/Polish Removers must be avoided as they contain Fragrance Oils and other contaminants that may reduce Thermal Conductivity.

02. How about using a better Thermal Compound than Arctic Silver 5?
A: Any Thermal Compound better than Arctic Silver 5 may be used. However, they may not be easily available and reasonably priced as Arctic Silver 5.

03. How about using Arctic Ceramique instead of Arctic Silver 5?
A: The Thermal Conductivity of Arctic Ceramique which is >200,000W/m sq °C @0.001in is lower than that of Arctic Silver 5 which is >350,000W/m sq °C @0.001in.

04. How about the System Board circuits getting shorted due to Arctic Silver 5 spillage?
A: Arctic Silver 5 is Electrically Capacitive only at high pressures and any spills can be easily cleaned up with Isopropyl Alcohol. There is no need to use Arctic Ceramique only because it is a pure Electrical Insulator.

05. How about using the Thermal Compound ideally?
A: The ideal amount of the Thermal Compound is equal to about half the size of an uncooked short grain of White Rice. It should be applied directly only on top of mating surface of the actual core and its Thermal Cooling Assembly and then spread evenly using a Thermal Compound Spreader. Increasing the amount of Thermal Compound may decrease its Thermal Conductivity.

06. How about reusing the existing Thermal Compound on the CPU and its Thermal Cooling Assembly?
A: The existing Thermal Compound on the CPU and its Thermal Cooling Assembly may be reused as long as the original CPU and its original Thermal Cooling Assembly are reassembled together. However, it is not recommended.

07. How about using Aluminium instead of Copper?
A: The Thermal Conductivity of Aluminium which is ~ 237 W/(m·K) @300K is lower than that of Copper which is ~ 401W/(m·K) @300K and the Thermal Expansion of Aluminium which is 23.1 µm/(m·K) @25°C is higher than that of Copper which is 16.5 µm/(m·K) @25°C.

08. How about using Bronze, Brass, Gold, Silver or Diamond instead of Copper?
A: Bronze and Brass have poor thermal properties and Gold, Silver and Diamond are not cost effective when compared to Copper. Refer to the List of Thermal Conductivities for more information.

09. How about using the Copper Mod on the Northbridge Chipset?
A: The Copper Mod may be used on the Northbridge Chipset. However, it is not recommended as the Thermal Cooling Pad is more than adequate for the Northbridge Chipset.

10. How about the Thermal Cooling Pad positions?
A: The Thermal Cooling Pad is usually on the Thermal Cooling Assembly. However, in some cases, it is on the Chipset. The position is immaterial as long as it makes a perfect contact between the Chipset and its Thermal Cooling Assembly.

11. How about the Thermal Cooling Assembly variations?
A: All variations of the Thermal Cooling Assembly can use this Copper Mod. However, in some Thermal Cooling Assemblies, the Copper Sheet must be placed under the GPU Thermal Cooling Assembly, between the raised boundaries, for a proper fit.

12. How about the Copper Sheet fit?
A: The ideal size of the Copper Sheet is 14x14x1.5mm for all variations of the Thermal Cooling Assembly. However, it is recommended to place the Copper Sheet without the Thermal Compound to check the fit. It should fit perfectly in the gap between the GPU and its Thermal Cooling Assembly. It should not be loose enough to fall off or tight enough for no expansion.

13. How about tightening the Screws ideally?
A: The Screws are tightened ideally when they cannot be turned any further without applying pressure. Overtightening the Thermal Cooling Assembly Screws may damage the GPU as the Copper Sheet slightly expands due to heat during the normal use of the Notebook.

14. How about curing the Thermal Compound ideally?
A: The Thermal Compound will take several hours (around 200 hours for Arctic Silver 5) and several thermal cycles to cure as long as the Notebook is turned off from time to time and allowed to cool to room temperature. Once the curing is complete the Notebook can be left turned on if desired.

15. How about the benefits of this Copper Mod?
A: This Copper Mod reduces the GPU temperature by a few degrees when idle and several degrees when loaded, CPU and Chipset temperatures by a few degrees. The Notebook will run comparitively cooler and quieter with the Fan on slow speed.

16. How about reversing this Copper Mod?
A: This copper Mod can be reversed completely. The existing GPU Thermal Cooling Pad may be reused to reverse this Copper Mod. It is recommended to reverse this Copper Mod before sending your Notebook back to Dell.

Updates:

July 8, 2009: Celebrating 1st Anniversary of Dell XPS M1330 - nVidia GeForce 8400M GS - Copper Mod. My notebook is running great without any spares, service or repair!

December 21, 2009: My Dell XPS M1330 notebook's LED backlight switches off and replacement screen or cable does not correct the problem although external monitor (via VGA or HDMI port) displays video flawlessly. Dell's technician suspects heat from the wireless card breaking up the circuit and suggests replacing the motherboard for correcting the problem. With this my first Copper Mod has lasted me for 531 days (1 year, 5 months, 1 week and 6 days).

December 28, 2009: The motherboard was replaced by Dell's technician today and I have redone the Copper Mod.

Just an update for people though, if you're buying new thermal paste, I suggest Arctic Silver Ceramique. It's totally non-conductive and has a better heat transfer rate than AS5. I just happened to have AS5 laying around.

Thank you.

Arctic Silver 5 vs Arctic Ceramique:

Thermal Conductance (0.001 inch layer):
>350,000W/m sq °C vs >200,000W/m sq °C.

Thermal Resistance (0.001 inch layer):
<0.0045°C-in sq/Watt vs <0.007°C-in sq/Watt.

Peak Extended Temperature Limits:
–50°C to >180°C vs –150°C to >180°C

Long Term Extended Temperature Limits:
–50°C to 130°C vs –150°C to 125°C

Performance (CPU Full Load Core Temperatures):
3°C to 12°C Lower vs 2°C to 10°C Lower

Arctic Silver 5 Cons:

Electrical Insulator:
Electrically Capacitive vs Pure Electrical Insulator

Curing Period:
200 Hours vs 25 Hours

How is Arctic Ceramique better than Arctic Silver 5?

Hep! · 07-02-2008, 07:36 PM

Hmm, you might be right. I remember reading a review of a whole slew of thermal compounds and ceramique came out number 2, next to some hard to find expensive stuff.

Shame I already just ordered my tube of AS Ceramique not 5 minutes ago. Sighhhh.

You know leave it to me to go and do something like that too, I bought the 22 gram tube since I build about 3 computers daily.
Oh well, this can still go in them v_v

johnny13oi · 07-02-2008, 07:56 PM

There are several places selling this and I was wondering if we could set up a group buy. I remember one place in the US was selling this for 50c each but the shipping was $12. So a group buy would probably drop the price of each total down to just several bucks. Anyone with a respectable account on here willing to do this?

MexicanSnake · 07-02-2008, 09:29 PM

Awesome guide but would be even better with some pics for n00bz. Ill buy some copper now

Great guide and well written.

If anyone is after thermal paste, I suggest Arctic Cooling MX-2. It is non electrically conductive. Its much easier to apply than ceramique and you can easily get a thin layer, in tests it has been proven to be on par or beat AS5.

I m tempted to finally do the copper mod because of the hot summer weather my M1330 is running even hotter. But I personally dont see why I should do Dell's job for them. Dell will just have to keep changing my motherboard at their expense until they decide to do something proper about it.
