NOTE: The bottom of the HSF that ships with the boxed Pentium 4 comes with a thermal phase change pad installed. If you wish to use a more effective thermal interface such as Arctic Silver thermal compound then you will need to first remove the pad from the heatsink. The pad is most easily removed by using a combination of isopropyl alcohol and a flat dull object such as a old credit card. Be careful not to scratch the bottom of the heatsink too badly when removing the pad as this will decrease the thermal transfer effectiveness.  
 
Follow the directions supplied by the manufacture of the thermal compound you are using to apply a thin layer of the thermal compound to the top of the CPU. Avoid getting the thermal compound on any circuit board traces. Make sure the thermal compound only contacts the metal top portion of the processor. Do not apply compound if you intend to use the thermal phase change pad that comes with the retail box heatsink. Using the pad and thermal compound together is worse then using either one alone.

y a quelqu'un lol

Oui il faut l'enlever, mais j'ai deja repondu a ce topic dans hardware

Il faut l'nlever quand tu mets de l'Artic silver, sinon tu le laisses, c'est fait pour les gens qui n'ont pas de pathe thermique !!

 
désolé claps et merci encore pour tes reponses
j'etais un peu impatient, tu connais losque qu'on a une nouvelle config et comme personne ne repondait j'ai multiplié les threads voili voilou
