According to Intel, maximum operating temp for 5472 is 67C (153F).
But this is external temperature (measured outside heat spreader).
Some PC overclockers reported 75C (167F) as thermal throttling barrier.

Some interesting info from Hardware Monitor developer:

So I guess air flow is not a problem.The warmer one got as high as 58C during the test (which is only 2 min long). This doesn't seem that high but I don't really know. I've always heard not to let anything get above 80C, but I don;t know what the consensus is on that. I'm not too worried about it I guess. I may run some longer tests and see what I get. I've read that if it gets too hot it should shut itself down and that hasn't happened to me yet. But I would like some comfort in knowing it won't reach that point if I ever do more processor intensive stuff. Now all I do is play x-plane and maybe edit some photos now and then but it is usually on about 16 hours a day depending on if it feels like going to sleep or not.. My eSata card seems to not let it do that sometimes.
Sounds to me like you are in good shape. I plan eventually to do some processor intensive stuff. If there are any developments, I'll post it here. You do the same.

Does anyone know if the there is a 6 Core Xeon, which would be compatible with the 3,1 Quad MP?

**Apparently, there are not. This class of Xeon only was made in Quads.

starting with a dual processor 2.8 3.1, is there much real world benefit to upgrading to the 3.0 processors?

I have a 3.1 and upgrading to SSD made huge difference and also ram (but it's silly expensive). Both of those, as well as potentially graphics card if you are using apps optimized for GPU will make FAR more improvement than a small bump in CPU speed.

I just put in 32gb of Crucial server memory. It is 667 but it was so much cheaper. Waiting to see how it works out. I have had to replace a couple drives and am rebuilding still. also making the switch to MAverick if it all works out.

Upgrade that old MacPro super easy.

I disagree.. I got the extra heat sink and a set of two X5482 processors and upgraded my single E5462 early 2008 MacPro (3,1) to dual X5482s for $225 shipped in parts from eBay. My Geekbench score went from 4300 to 13800 on Mavericks.

Well worth the $225 and 30 minutes I spent!

I did not have to re-install the OS or do anything.. just two about 2 extra minutes to boot the first time and my system actually runs 10-15 degrees cooler.. even running BOINC @95% cpu and all CPUs pegged out..when that isn't occurring it runs even cooler.

Total conversion time for me was about 30 minutes once I had the parts and tools. The 6-9" 3mm hex wrench is critical.

This video on YouTube shows how easy it is: https://www.youtube.com/watch?v=xYvlojzqjS8

I also previously performed the SSD upgrade tapping off the motherboard and using one of the 5 1/4 bays as well as upgraded to a GTX 260. All recommended upgrades.
