Is Intel’s Thermal Paste ACTUALLY That Bad?

Is Intel’s Thermal Paste ACTUALLY That Bad? walks through a hands-on experiment by Linus Tech Tips to evaluate the quality and impact of Intel’s thermal interface material (TIM) over multiple generations. The video opens by addressing a common belief in the community that Intel uses a suboptimal paste between the CPU die and the integrated heat spreader, and it notes that traditional testing is confounded by many variables when the IHS is removed. The crew devises a method to harvest TIM from several old Intel CPUs and compares it against a high-end Noctua TIM with a premium cooler. The setup includes a controlled baseline using Noctua NT-H1 and a stock cooler to measure performance, while ambient temperature is kept constant to isolate material performance. A key segment shows the elaborate “TIM harvest” process, where CPUs are opened and the paste is scraped for later testing, followed by an exploration of how to reconstitute and apply the paste for a meaningful comparison. The test then proceeds with applying the reconstituted TIM and monitoring temperatures under load, documenting how the recovered paste behaves when pushed to its limits. The video emphasizes that there are many variables in play when delidding and reapplying TIM, such as mounting pressure, paste thickness, silicone seal integrity, and flatness of the heat spreader, and concludes that Intel’s longevity-focused TIM strategy, rather than pure performance, drives much of the observed results. In the closing analysis, Linus explains that while the reconstituted paste can reach usable temperature ranges, it remains clearly inferior to modern, solder-free, performance-oriented pastes, and emphasizes the broader context of testing methodology and product design choices. The video ends with practical takeaways on testing practices, a candid acknowledgment of the experiment’s limitations, and a call for better sample availability from Intel for more definitive comparisons, alongside a plug for sponsor messages and channel encouragements to subscribe.Overall, the episode blends humor with a methodical teardown, delivering both entertainment value and a discussion about what TIM actually contributes to real-world CPU cooling and longevity, while balancing the constraints and variables of such experiments.
