jeffmr4 Posted February 18 Report Share Posted February 18 Hello, I am replacing the logic board and cpus in my dual 500 gigabit g4 and am wondering if I need to use thermal paste for the cpus. From the heatsink I took off of my board I just see a rectangular piece of black tape/plastic (very thin, ?) on the heatsink and a small piece of plastic over the cpu. But, I don't see any previous paste. Does anyone know if it requires it? Thanks. Quote Link to post Share on other sites
beachycove Posted February 18 Report Share Posted February 18 Apple did use that thermal tape stuff on some G4 processors; I found it, e.g., in my 12” G4 PowerBook 1.5 when I took it apart. I am pretty sure, though, that my G4 towers have had heatsink grease on there, and personally I would use it in preference to the tape. Quote Link to post Share on other sites

PowerMac_G4 Posted February 19 Report Share Posted February 19 @jeffmr4 I always use thermal paste on G4s - they always benefit from it! Any non-conductive paste will do the job. Quote Link to post Share on other sites
