The only problem I had with my accelero sinks was my fault, I accidentally hit one of the sinks with my L clip and it fell off and landed on the fins, with a small screwdriver and some finger skill I stuck it back up, other than that I don't know why people are having a difficult time putting the sinks on, Ive read a few reviews on the egg with the same problem. Don't be afraid to use a little pressure, which I think is what people aren't doing, I grabbed my board by both ends, one finger on the opposite side of the ram module and my other hand pressing the sink. This way I provide even pressure to not warp/bend the board. Since the install none have fell off. I think it was people a little afraid to put a little umph into it. You can maybe try my method but I believe after 1~2 trys the material may lose its tackyness. Cant hurt though, just make sure you get rid of the ESD, or use the strap.
