W3503 Xeon @ 130W TDP vs Pentium D 920 @ 95W TDP

[idata]

I have a single processor Dual Channel DDR2 Non-ECC Pentium D Computer at 95W TDP.

I want to upgrade to a single processor Tri-Channel DDR3 ECC W3503 computer at 130 W TDP.

I am concerned that the "server grade" W3503 @ 130 TDP is thermally inferior to the "consumer grade" Pentium D @ 95W TDP.

If I tortuer both CPUs at 100% load which processor will:

1) Die first?

2) Throttle first?

3) Rev up the fan first?

4) Perform erroneous computations first?

Thanks,
