I haven't ordered computer boards, but I did order a Peltier laptop cooler similar to this one[0] with a silicone aluminum pad rather than gel, and it came exactly as pictured. It could be stronger but it's pretty much what I expected. I thought at worst it's a nice portable aluminum stand and I can replace the cooling unit if necessary.

Does the laptop cooler actually work?

Yes, but a good laptop cooler fan is better. The Peltier cooler also has a fan so isn't silent but certainly quieter. I use it propped up at a high angle (with external keyboard) which has a good display height and natural convection cooling.
