Oh, the seconf pipe fits right next to the CPU heatsink, inside the laptop there is about a 1 1/4 inch gap from end of the cpu pip heatsink to the edge of the laptop vent it shape like a perfect square and wej you aline the card it fits right in that area, I woulp hope on a dual pipe, because it would most likely run cooler due to the second pipe. and may give you more clocking head room. When i had my 7900GS single pipe the highest playable 24/7 clock i could achive was 625\1250 but i modded the bios and flashed it with a 1.24v setting apposed to 1.0v. Also a 6 cell will be fine and only on the 7900GS YOU CAN USE YOUR 90w, even at the o\c settings. I had posted a chart in another forum i think that the 7900gs only eats 20-25w while the ather three othe 7xxx series suck up 40-45w. The main reason is sold my GS is becuase i sold my New single pipe for $269 and got a brand new 7900GTX for $499 so totla upgrade price out of my pocket was $230, pretty wise investment if you ask me. Below is a link on removing or adding dual piped cards:http://support.dell.com/support/edoc....htm#wp1006368
Putting in a single or dual pipe 7900GS or a 7900GTX is very easy itLiterally pops right in with no adjusting or modding as if it was made to fit.The 7800 GTX was a pain, i had to bend the pipes a bit, I had to cut a metal keyboard support beam of the motherboard and it felt cramped going in. That was another reason i chose to keep the 7800GTX over the single piped 7900GS, plus in realtime gaming the 24pp\8 of the 7800GTX shine through over the 7900GS 20pp\7Back to the poiny of overclocking the GS I took it form stock 375/1000 and kept mine for ful-time use at 600\1200, I felt better about the temps, i just didnt fel safe at 625\1250 for 24\7 use, but remember all cards overclock different. If you dont mine me asking how much did you pay for your GS? and where did ya get it. I could of gotten ya a great deal on cards, for future reference.
