So, I recently got a Dell Inspiron 5570 with a 15.6 inch (diagonal) screen, 1920 x 1080 resolution, i7-8550U (1.8 GHz to 4.0 GHz , 4 cores, hyperthreading, turbo and low power consumption) , CD/DVD+-R/W, 32 GB RAM, 1 TB SATA HDD, 4 GB Race n Graphics and installed Win 10 Pro. I mention the laptop specs in case other potential buyers want to compare this NVMe SSD to their own computers As fast as this laptop was already straight from Dell, the HDD just slowed it down. I knew I could replace the HDD with an SSD wanted to replace to store programs, and another M.2 SSD card to boot will definitely speed up my laptop even more, and when designing and rendering 2D/3D animation, HD video editing, etc., the speed is never fast enough. Well, heavy use of electronic components generates heat, and heat generation can become a very serious problem. On most laptops, including mine, the space above the M.2 card once installed is only enough to allow light jets of air to circulate over the component, certainly not enough space to install even the lowest profile heatsink. or so I thought. Introducing the Advancing Gene Heatsink for PCIe M.2 Solid State Cards. I was able to install it and properly close my Dell laptop's case without the slightest bounce or deformation of the back cover. It's tight, of course, but it fits. Wow! According to the product description and others who have independently tested this should reduce the temperature of your PCIe SSD by 5-10 degrees. Brilliant!
