 ## Known Issues
 ### Liquid Metal Pump Out
-On Framework Laptop 16 devices with liquid metal thermal interface material, performance may degrade over time due to the liquid metal pumping out of the CPU.[^11] To address the issue, Framework switched new production laptops to use Honeywell PTM7958 phase-change thermal interface paste. Owners of laptops with liquid metal can request a Honeywell PTM7950 thermal pad from Framework.[^12] Framework says the PTM7958 has "equivalently strong" performance to the original liquid metal.
