Upgrading Mac Pro CPU

[wonderspark]

I also upgrated my mac pro 2010 from a xeon 2.8GHz to a xeon W3680 3.33 GHz. Everything sems to work fine... The only thing i m concerned about are the high core temperatures.... somethimes that goes up to 80 C ... can anyone tell me if thats normal? because that seams a little high....

80C is really hot. I've pushed mine to 66C when rendering a long video project. During normal use, I see 43C at the most.

According to this Intel spec page the Tcase is 67.9C.

Did you apply the thermal paste correctly? How are you measuring 80C?

mhh... yes i have been reading that too... i just wonder why it gets hot? The fans are all working and thermal paste is also applied correctly.

thanks for tha fast response

I m measuring the temperature with "hardware monitor" ... and i think speedfan in windows (in windows i can only measure the core temps. and not the tcass) ... i also reseted the smc fan control settings of the mac allready...

For what it is worth running X5355 on a Mac Pro 1.1, the bench tests improved by 92% to 9416, with an OWC SSD. With the X5365 imagine it would be around 102%?

I'm very interested in the CPU upgrade, and SSD. Wondering about ML compatibility which the MP1,1 does not have. Do upgrades affect this one way or the other? I heard that the issue with ML (Mountain Lion) was not the CPU rather the mother board??

If I upgrade, I will keep the MacPro. I'd be interested in the CPU upgrading techniques discussed in other threads also. How will this tie together on the ID of the MP as a later version? Would my upgraded machine be equal to 2,1 or 3,1 versions?

In the 1,1 Mac pro that is correct. The x5365 is as good as it gets

Is there an option to enable MP 1,1 to run ML (Mountain Lion) OS X? From what I hear it is more than the CPU upgrade, though. Please let me know.

Yes, I've done it. It looks a bit more complex than it is though. Essentially you load an alternate boot loader (chameleon) and away you go. This thread is a good place to start.

What I plan on doing is making Mountain Lion my main OS once the GM hits. I'll have a small lion partition to fall back to as well.
