1080Ti gigabyte evga fans and other questions

[ah4444]

Hi,
Im looking at the 1080ti cards from evga and gigabyte. For some reason i find myself obsessing over the 3 fan models and neglecting the 2 fans. Only now have I just questioned myself, "why do I care?"
1. Apart from an extra fan do 3 fan models have anything else special with them. Would I be missing out. (maybe a longer lifespan, if anyones bothered to calculate that)
2. On newegg there are multiple aourus gigabyte 1080ti's, with slightly different id numbers but huge differences in price. these two what am i missing

Im not actually buying from them as I just found I lose my savings with vat and import duty (gets me everytime).
Thanks in advance.
EDIT: it seems like clock speed is a factor in the price but the differences in these speeds are around 40Mhz

i can see only one model on the link that you give.anyway most of the superclock/oc version of the card would have more fans that the standard version.it might help in cooling the card but it all falls down to your case cooling capabilities.card prices seems to get pretty high nowadays so yeah even an increase in speed could factor the price drastically.
