moi aussi j'ignorai que certain PIII tualatin taient collés au ventirad en usine . voilà la réponse d'Intel :
Hello,
Thank you for contacting Intel(R) Technical Support.
I understand that you would like to know how to remove the heatsink from your Intel(R) Pentium(R) III processor at 1.2 GHz.
To remove the heatsink try using a hair dryer, and twist the heatsink as you separate it.
Please do not hesitate to contact us again if you need further assistance.
Sincerely,
Bob R.
