OpenBSD 5.8-current enters deeper C states than the ACPI describes. The ACPI documentation is not to be taken literally, according to Intel. So now OpenBSD's behavior should be similar to Linux in this regard, and therefore, you'll see lower CPU temperatures. (With the C states and mwait features that are enabled today, your temps are already lower than previous releases.)
