    That is a bummer, I was ready to get my hands dirty.

    In other words i understand it may seem like an expansive upgrade but over here it's not, especially if i can pay bits by bits. Everything works fine but the fans that are running high for no reason.
    This is why I suggested adding your location to your profile. Sometimes if someone is from a more isolated geographical location (at least isolated in terms of getting Macintosh/Apple help)...we can try to be as creative as possible with suggestions.

    Not to be disrespectful to the folks of New Caledonia. But I'm guessing that there may not be that many "Macintosh/Apple" experts on the island. We as Macintosh users are in a big minority when it comes to computers...and on an island such as New Caledonia...Macintosh experts may be few and far between.

    Given that the person that did your Mac Pro upgrade is telling you things that aren't true (that this fan thing is not a big deal & is normal)...I'm guessing he may not be an Macintosh expert...at least not in a world-wide sense (he may be a "New Caledonia Macintosh expert")!

    Heck...who knows...how many of these Mac Pro cpu upgrades has he done? Can't be too many...since he didn't get this one right. Maybe he was learning for the first time on your computer!

    Doing a cpu upgrade on a Mac Pro is NOT a common procedure...even in other countries like the US, UK, Canada, Australia, etc. So even "experts" in these countries may not have done many (or any) of these upgrades on a Mac Pro.

    I'm not sure what else to suggest...other than make sure that this person who did your upgrade is not fully paid before things are sorted out.

    Good luck,

    Trust me you're not being disrespectful at all, there are lots of useless people out here. But thankfully the person who did the upgrade is no the person who thinks the fan issue is normal. He's is looking at this whole calibration thing right now and I trust he'll be ok. He does a lot of good work on lots of gear.
    It was when i called the only apple repair store that they told the issue was ok and right there i lost my faith in them, plus they charge their price like crazy.

    I'll let you know if the calibration pans out. Thanks for your help

    Sounds great...good deal. Glad to hear you have someone looking at it that you trust!

    Looking forward to how things work out.

    For what it is worth when I installed X5355 CPU's in Mac Pro got the jumbo jet fans roaring. Solution was simple. Under the heat sink is a small heat sensor plug which had come detached. Replaced and back to normal quiet Mac Pro.
    Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    Nice little detail Harry. Thanks for mentioning it.

    I had the same issue today
    The last note on this thread nailed it. I upgraded my old 4 core processors to the 6 core x5690's in my mac pro mid 2010. I didn't screw the heatsinks completely into the motherboard so the sensors were not fully attached. I just pulled out the tray and screwed them in until they couldn't go any further. Threw the tray back in and my 8 core is now a silent silky smooth 12 core.

    Bought a pair of pulled x5690 for $200
    Artic silver paste, the cleaner and rag

    in total $250

    Don't get the turnkey BS on OWC.
