What boost clock speed is your card achieving at this temperature and what fan RPM are you seeing?80C is a perfectly acceptable temperature for this 1070, the cards are designed to automatically overclock until they reach their thermal target which is 83C for the Gigabyte ITX card, once they hit their target they start to reduce the boost clock speed in combination with the fan profile to keep temps at a steady 82C/83C. Have you tried changing the fan profile in the Gigabyte software to the 'silent' profile? You will get a much lower noise level at the expense of an few extra degrees temp and maybe a slightly lower boost clock speed.Don't forget the card is automatically overclocking above its rated boost clock (1721Mhz) before it reaches its thermal temperature, I have this card and mine runs at around 1750Mhz - 1800Mhz at a temp of 82C/83C with fan profile set to silent running at roughly 1550rpm which is fairly quiet. Its not really thermal throttling until the clock speed drops below its rated core clock (1531Mhz), its only at this point I would start to worry about the thermal performance of your setup.Is the hassle and expense of water cooling the GPU worth it to get those extra few boost clock MHz? In real terms you may see 1 or 2 extra fps in a game so maybe it is? But if not then you can try messing around with the Gigabyte software to see if you can get more acceptable noise levels and still keep 99% of the cards performance.
