yes, and if the latch on the CPU wasnt open when you removed the heatsink, and the CPU came with it, dont worry, its happened to me- i mean technically, wouldnt that basically bend all the pins on the P4? and then i look, and no. the latch on the socket 478 was shut, but the processor was stuck to the bottom of my heatsink, and the pins were fine, and wearing gloves, i pulled it off and put it back in, and all was fine.
