Unless you just don't have the space for it, i'd suggest you at least go with a
60mm to 80mm fan adapter and then a quieter, but more powerful
80mm fan
The BIG question might be, what's "a nice copper heatsink"? Generally speaking, there's no trick to heatsinks that'll do away with large surface area, and a 'sink using a mere 60mm fan probably has so little surface area, efficiency, that it's necessary to use that high-RPM, loud little 60mm fan. A lower RPM 60mm fan puts out a lot less air than a 80mm fan anyway, then coupled with the smaller 'sink it's not so great a cooling solution except for running at stock speed & voltage.
To more directly answer Budarow's Q, yes the fan can be thicker than 25mm IF it uses a standard mounting (screws) mechanism, but 60mm fans thicker than 25mm are few and far inbetween. It's not all that easy to even find a 80-92mm fan in excess of 25mm thickness unless it's an exceptionally high-airflow, quite loud model. Of course there's the good ole voltage-reduction hack, but it makes less sense to
plan doing that to a fan you haven't bought yet, compared to reusing a fan you already had.
Fan adapters can reduce noise but somewhat impede airflow. Probably be a lot better to just buy a cooler that takes an 80mm fan if you want to fully exploit the o'c potential of these chips.
