Copper Heatsink 70x20x1.5mm with Thermal Pad and Rubber Ring for M.2 SSD Memory, PC, Laptop Cooler 1 Set

Well machined, good price, the rubber rings that help secure the heatsink to the thermal pads are good quality too, but that thermal pad is truly junk, bottom of the barrel and certainly will hurt your performance. It's far to hard and inflexible to fully mold around the nand controller chip or the nand chips among other components on your 2280 nvme. Also the thermal conductivity sucks too. Spend an extra 9 bucks for the very soft and pliable ARCTIC TP-3: Premium Performance Thermal Pad, 120 x 20 x 1.0 mm pads, when installing the heatsink remove the sticker on top of the nvme drive, "that will lessen thermal conductivity slightly if you don't, then clean the nand chips and controller with a damp qtip with 91 percent isopropyl to remove any glue residue, then after trimming the thermal pad to size preferably with a sharp xacto blade, put it evenly on the back of the heatsink after first cleaning the back of the heatsink with rubbing alcohol to shine it up first, get it Lined up on the nvme, then put medium pressure on the heatsink, in the center then on both sides at the same time, go back and forth a few times ensuring that the heatsink doesn't move after as you don't want air bubbles trapped under the pad, adequate pressure is good which will push down the thermal pad onto all of the components getting rid of any trapped air and increasing thermal conductivity, wear powder free gloves too so the oils of your skin don't come into contact with the copperheatsink or thermal pads "skin oil is slightly acidic and can tarnish the copper over time and potentially react with the thermal pad" then you'll be happy. Be careful not to pinch or crush those softvartic pads as they will not spring back and will be very much molded to any pressure. Which when mounted cotmrrectly is what you want, also becareful not to stretch the pad either when installing. My Samsung 980 is a whole 10 degrees cooler at idle went from 46 and idle even in efficiency mode to 36 at idle at high performance mode, it hardly breaks 45 to 46 degrees under full load for 15mins, in my thin and light laptop and does not get above 54 degrees c under full load after an hour of beating my drive up. Install it right and you'll be happy.
