Navigating the Challenges of Selling a Delidded CPU: A Cautionary Tale

Selling computer hardware online can be a rewarding yet challenging endeavor, especially when it involves delicate components like a delidded CPU. Recently, I encountered a situation that underscored the importance of thorough communication and proper care when dealing with high-performance processors.

I sold my delidded Intel i7-7700K, which features four cores and eight threads, to a buyer who seemed eager to take on the task. To ensure a smooth transaction, I provided an extensive set of instructions—over 1,700 words—complete with links to relevant guides and video tutorials. In addition, I included the remaining Thermal Grizzly Conductonaut that I had used for the delidding process and cautioned him about the importance of applying the right amount of liquid metal on both the die and the custom copper integrated heat spreader (IHS) that came with the processor. I stressed that using too little could lead to overheating and potential damage.

However, my buyer seemed to overlook these warnings and decided to apply the liquid metal on the die alone, neglecting the IHS entirely. He also jumped into gaming without monitoring temperatures, despite my recommendation to use HWiNFO64 to keep an eye on core temperature discrepancies. Reports indicated that he was experiencing a significant drop in performance—only two cores and four threads were registering in Task Manager and CPU-Z.

Initially, although the processor was correctly recognized in the BIOS of his Asus Prime B250M motherboard, misconfigurations in software settings could have been the issue. After guiding him through the process of checking the msconfig settings—ensuring “Normal startup” was selected and adjusting the advanced boot options—the problem with the cores was resolved. All four cores and eight threads were finally detected. However, this improvement was somewhat overshadowed by his alarming idle temperatures.

Concerned about potential overheating, I suggested that he should reapply the Conductonaut, ensuring it covered both the die and the IHS, as I had advised repeatedly. Nevertheless, I found myself hesitant, worried that further mishandling could exacerbate the situation or lead to additional complications. His primary focus remained on gaming performance, not fully grasping the intricacies involved in maintaining a delidded CPU.

After addressing his initial concerns and seeing the processor functioning properly, I felt it was important to reiterate that the effective handling of the CPU was ultimately his responsibility. Prior to the sale,
