I would give this 5 stars if the thermal tape was already attached. The squares aren't all cut evenly though, and because the heatsinks are so small, it's difficult to align them without overlapping, and then you can also get blisters that you hope will flatten out and not have air pockets . when you put them in place. I took some 20mm radiators from other brands and they came pre-fitted. You can see the difference by looking at this: these have the bits dangling to one side because it's almost impossible to align them properly. Otherwise they heat up well, dissipating heat away from my backplate and tape. , at least for now, is pretty sticky and stays sticky despite the crazy heat my GPU puts out.
