Discussion Overview

The discussion revolves around the effectiveness of the Nexus TDD-3000 heatpipe system for cooling laptops. Participants explore its design, functionality, and performance in practical applications, including personal modifications and experimental comparisons.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant questions the placement of the heatpipe, suggesting it is not optimally located to manage heat effectively, particularly in the center of the laptop where heat is most concentrated.
  • Another participant proposes an experimental method involving boiling water to quantitatively assess the cooling performance of the heatpipe system.
  • A different participant shares their experience, noting that the heatsink does not seem to dissipate heat effectively, as the entire cooler heats up without significant heat transfer.
  • One participant argues that while the heatpipe may increase the surface area for heat dissipation, its size relative to the laptop's surface area may limit its effectiveness. They suggest that a better radiator design could improve performance.

Areas of Agreement / Disagreement

Participants express differing views on the effectiveness of the heatpipe system, with no consensus reached on its performance. Some advocate for experimental validation, while others share anecdotal experiences that suggest limited effectiveness.

Contextual Notes

Participants mention limitations in their observations, such as the lack of accurate temperature readings and the need for controlled experiments to validate claims about the heatpipe's performance.

This product, which I currently have, claims that the heatpipe system can draw out the heat... well... As you can see on that site the heatpipe is at the worst places beacuse the center of the laptop is where it displaces most heat and where a few heatpipes should be...

I modded this by adding a few extra fans via USB. :)


But I don't know how those are working because my ACPI d4mn isn't updating my CPU temp. :( :(


Does this model physically work or does what it claims?


Anyone? Anyone? :)

1. Bring two identical pots of water to a boil.

2. Remove pots from heat, wait a few minutes.

3. Place one pot on the laptop cooler, place the other one on whatever table you normally rest the laptop on.

4. Put a thermometer in each pot; record temperature versus time for several minutes.

5. If you're not interested in doing this yourself, find a middle school kid and get her to do it as a science fair project.

haha... I did that for the the cooler already... the heatsink part of it doesn't seem to disappate heat... Rather, the whole cooler heats up and the heatpipe gets hot... But it doesn't "move" anywhere...
 
If the pipe heats up, then it's increasing the surface area over which heat can dissipate into the cooler environment.

Now that I think about it, though, that pipe is not that large compared to the surface area of the laptop that's already getting fairly hot.

I still think you should compare two pots with thermometers (as opposed to qualitative 'it-still-feels-hot' measurements), but I don't think they'll be much of a difference.

The wicking-system might work, but it really needs a good radiator, maybe in the form of a mesh 'skirt' that hangs down over your knees when the machine sits on your lap.
