I would recommed GTX1070 with tri-slot cooler (models like Gigabyte Extreme Gaming or Palit JS-SJS-GR-GRP). Even during hot summer this cooler can provide enough cold temeparature
Also GTX1070 is quite cheap but still has good mining potential on various algos
Thank you for your recommendations. Like a country as hot as I live in, cooling is one of the main problems of course. Especially in summer.
