so you would rather recommend 1.5 on the back and 2 on front correct? Is this the one? > https://www.amazon.com/Gelid-Solutions-GP-Extreme-2-0mm-Thermal/dp/B07BSPZTNV/ref=sr_1_3?dchild=1&keywords=Gelid+2mm&qid=1620228639&sr=8-3
Also how many of them did you need for back and front?
From amazon, I ordered this one, in 80x40x2, and it came just fine, I also ordered this one, in 120x120x1 and it came all squished to hell. For the larger (120mm) sizes, the packaging is really inadequate, though YMMV. Finally, I ordered this one, in 90x50x1, and it was fine as well. All seemed to be legit.
