We've got a new thermal paste applicator tool that'll help ensure consistent, equal spread of TIM across cooler surfaces for future tests. As we continue to iterate on "Hybrid" DIY builds, or even just re-use coolers for testing, we're also working to control for all reasonable variables in the test process. Our active ambient monitoring with thermocouple readers was the first step of that, and ensures that even minute (resolution 0.1C) fluctuations in ambient are accounted for in the results. Today, we're adding a new tool to the arsenal. This is a production tool used in Asetek's factory, and is deployed to apply that perfect circle of TIM that comes pre-applied to all the liquid cooler coldplates. By using the same application method on our end (rather than a tube of compound), we eliminate the chance of users changing application methods and eliminate the chance of applying too much or too little compound. These tools ensure exactly the same TIM spread each time, and mean that we can further eliminate variables in testing. That's especially important for regression testing.
This isn't something you use for home use, it is for production and test use. When cooling manufacturers often fight over half a degree of temperature advantage, it would be unfair to the products to not account for TIM application, which could easily create a 0.5C temperature swing. For consumers, that's irrelevant -- but we're showing a stack of products in direct head-to-head comparisons, and that needs to be an accurate stack.
Here's the video showing the new tool:
Just to re-iterate: this is not a consumer tool. We are using the GN TIM Applicator for testing purposes, and you can now rest easy knowing that regression testing on GN will account for the difference between factory TIM and TIM applied later -- because we're using the very same application method, with this silk screen tool.
