This is a no frills branded dual heatsink set. I have one on Samsung 970 Pro M.2 NVME and the other on ADATA M.2 Sata. It works as it should. I saw a drop in temperature, but nothing out of the norm, around 7-8 degrees, according to my software readings. The installation is very simple, the heater fits perfectly and has no defects. The price and quality are amazing compared to some better known brand competitors. If you're a snob, spend double or triple to get the same result.
