Navigating the Challenges of Selling a Delidded CPU: A Cautionary Tale
Recently, I encountered an interesting situation while selling my delidded Intel i7-7700K processor, a promising chip boasting a 4-core, 8-thread configuration. I aimed to ensure a smooth transaction by providing the buyer with extensive instructions—totalling around 1700 words—and various resources to help them through the setup process.
Understanding the delicacy of handling a delidded CPU, I took care not to reseal the processor, sending it along with the remaining Thermal Grizzly Conductonaut that I had previously used. I explicitly informed the buyer that if the amount of liquid metal provided was insufficient for proper coverage of the die and the custom copper Integrated Heat Spreader (IHS), they would need to purchase extra liquid metal.
Despite my thorough warnings, the buyer proceeded to use the liquid metal rather carelessly and even ran a series of gaming sessions without monitoring the core temperatures, contrary to my advised best practices. Initially, he reported an alarming issue: his Task Manager and CPU-Z only recognized 2 cores and 4 threads.
His motherboard, an Asus Prime B250M, displayed the CPU correctly in the BIOS, but we had to investigate further. I guided him through several checks, including configuring the msconfig settings and ensuring he had the latest BIOS version, which he claimed was updated and even reset to factory settings.
Returning to Normalcy
Fortunately, after reiterating my instructions for msconfig and BIOS settings once more—and ensuring he followed them correctly—he could finally see all 4 cores and 8 threads in system monitoring tools. However, a new concern emerged: the reported idle temperatures were alarmingly high. I suggested he consider reapplying the liquid metal, ensuring coverage over both the die and the IHS, as I had originally stressed. Yet, I worried that he might exacerbate the situation.
An Ongoing Learning Experience
Reflecting on this transaction, I couldn’t help but question whether this buyer was adequately prepared for the responsibilities of managing a delidded CPU. Despite my best efforts to dissuade him, he was determined to proceed with the purchase. After helping him resolve the threading issue, I made it clear that the well-being of the processor moving forward was beyond my jurisdiction. I had fulfilled my role as a seller by offering a fully functional CPU and extensively communicating the potential risks.
