EZlifego Double Sided Tape Heavy... https://www.amazon.com/dp/B07VNSXY31 Did this and moved on

Not easily, but I can point you to what I'm using:

1. One of these fans. This is located a few inches behind my SP8 and is blowing (on the highest setting) directly at its center.
2. One of these dual-fan units. I've attached these directly to the upper back of my SP8 using this dual-sided sticky tape, which doesn't seem to leave a residue when I take it off.

If I knew for certain that two of the fans (1, above) would work as well as, or better than, using both 1 and 2, then I'd have gone down that direction.

What I'm doing works well, but I'd prefer to:

• Minimize noise;
• Maximize cooling; and
• Avoid adhesive.

That's why I'm exploring water-cooled systems designed for smartphones, like this one that I ordered last night, and another type of fan that connects magnetically to an iPad. (I'm not sure that it would work with a Surface, but it's inexpensive and looks cool, so I thought I'd give it a shot.)

Hopefully some combination of what I have and the above will enable me to achieve cooling at least as good as what I have now, ideally with nothing that needs to be attached via an adhesive to the back of the Surface, and with much lower noise.

I hope this helps.
