Nope... no size restrictions. Very strong, very thin Electrogalvanized Steel. Super stuff. This clip is great because its easy to use. place clip on the socket then place the PolarFLO on the cpu add the 4 screws and tighten! That's it! Plus it does not hinder or hide the beauty of the PolarFLO since it attaches at the bottom.

Here are a few pics...

Best to all.
