It's one of the worst GTX 1070 cards you can buy in terms of looks and cooling, but it's cheaper than the rest. Works OK anyway, I have used a few of them and while they don't looks like much I did not have any overheating problems, rather quiet too. This cooler seems to be effective enough for 1070 chipset. No backplate causes it to sag a bit over time.
