While initially booting, I’ll see the hotspot temp get to around 100 C while the core temp is around 55 C to 60 C before the fans begin to really ramp. Yeah, at this point I’m fairly sure this is the cause more than anything else at this point, that it’s basing the fan on a sensor that no longer heats up as quickly as it does when stock. For an example, if I run a quick Cinebench 23 run, the fan stays inaudible the entire run, even as the temperatures spike up like this. But a second run in a row the fan eventually kicks into gear. The first run is actually a little slower (like 200 points) than the second when the fan is running, which is kind of crazy since it’s the opposite of how computers usually behave. ![image](https://us1.discourse-cdn.com/flex001/uploads/framework3/original/3X/9/1/911d56ad10a41263cdc15228f7ca03280229c2dc.png) --- _[View the full topic](https://community.frame.work/t/honeywell-ptm7950-phase-change-thermal-pads-sheets-application-tips-and-results/20245)._
