Hi everyone,
I'm working on a project where the processor is attached to a copper tape about 8cm long where it sticks from 1 end of the processor case to the other while remaining length was insulated with a cardboard. the other end was slightly exposed for temperature measurement
The exposed copper tape on the processor is connected to a heatsink. (i.e processor case -> copper tape -> heat sink)
The strange thing is the copper tape is at ambient temperature when i force the heat sink fan to stop running but the heat sink itself is heating up.
I have done:
1. applied thermal grease on the copper tape and heat sink
2. remove any sticker residue on the tape so is only pure copper.
Is this a normal phenomena, if yes could you advice how does this relates to the theory of conductivity?
Thank you in advance
