I think this is the one I watched. I'm not 100% certain. I watched several different ones including reviews etc. https://www.youtube.com/watch?v=I8Z09nU554Q > >> I >> noticed on a couple heatsinks, they mention the difference and show they >> use a pad that makes full contact on both chips.

Some pads look really thin on cheaper devices while some appear thicker on ones costing a little bit more. A thicker pad has more ability to fill in the difference with likely not even a lot of pressure. A thin pad or what some refer to as tape which is not compressible much at all would likely not work as well unless you either put a lot of pressure on it or added a little pad to make up the difference. I did a ebay search and found the generic pads coming in from thicknesses of as little as .2mm to as thick as like 2mm or so. The 2mm thick one has lots of wiggle room to contact both chips and easily I'd think. The .2mm not so much but could if installed right, I guess. Tape would likely be the worst since it doesn't compress much if any. The mobo I'm getting doesn't have any heatsink at all. The original one did. To be honest tho, I'd prefer to put my own on there. On some older boards I have, the NAS1 box for example, I added some heatsinks to the little regulator things close to the CPU. They get rather warm when compiling packages. They not to bad when sitting idle tho. Those little heatsinks keep them pretty cool. If the current mobos didn't have a heatsink on those already, I'd likely add one that is much more efficient than what some mobos come with. It's like CPUs. They used to come with a cooler, it seems they don't anymore for most I guess. I've never used a OEM cooler because I want my CPU to run cooler than one you can almost cook a egg on. As I tell people, I build puters like a tank. I like everything to run cool and well below the max temps. I still can't get over how tiny that m.2 is. Kinda looking forward to the stuff coming in. I just hope the power supply cables are long enough. That Fractal case is rather large. About like my Cooler Master. Dale :-) :-)
