You mean due a lower TDP of the new proccys they don't need a bigger heatsink? Still, it looks like crud. I suppose it is fine for 99.9% of users out there. Any OC'er would change that for something like the TRUE/wb of choice etc.
Sensible move tbh. For OEMs its not gonna make the blindest bit of difference and anyone who builds the system themselves will have/be getting after market sinks.
