My news server dropped the previous posts. Please reiterate the
significance of this new heat sink setup. Are you overheating or just
loud? Both maybe?

If my rusty memory serves, you might be the one that had overheating
problems now that summer is here?

I just put in the supplemental 2.0 CD BIOS to my 2100z (dual 246's)
yesterday and didn't notice much if any change in cooling or noise. But
then again, there is no problem here.
