    Anyone notice that the new mac pro top memory riser is now inserted upside down?

    Wonder if Apple determined that it resulted in lower temps?

    Anyone with a new model, can you post temps once you get DIMMS on both risers?

    An airflow improvement. Particularly needed for the 3.2 due to hotter processors AND hotter FB-DIMM's.

    I can see the FB-DIMMS being slightly hotter I guess because the clock speed is increased, but I thought the CPU's ran cooler with less power?

    The 3.2 has the same thermal characteristics as the prior 3.0 ( 120 Watts TDP, HOT!! ) also the northbridge runs hotter due to the faster FSB.

    Wow....it will be interesting to see people post their internal temps. My 2.66 Mac Pro with 11GB RAM, some of the 2GB DIMMS can run standard around 150F...this is with the fans at the default lowest setting.

    Interesting to see if the new models are as quiet as the old ones with the fans. I know Apple have the limits set pretty aggressively before the fans kick up.
