Hi all!! Tonight im gonna change my 1700+ to the spanking new 2400+ i've got here sitting in a box. One question...i remember when i installed my current CPU/HSF there was some pink grease like substance on the bottom of the HSF that lined up with the middle of the CPU when attached. This is the thermal paste right? Do i need more of this or will the same HSF sit happily on my new CPU without it frying?! many thanks for some quick replies!!
