    Is it still possible to source a single socket processor tray for a 2010 model?

    Any suggestions would be greatly appreciated.

    Best to tear down a working Mac Pro 5,1 (2010-12) .

    The Tray by itself costs as much , if not more, and I think you need to build them up from new parts . For 600 USD , if you must :

    Funny thing, though , I just bought a single processor Mac Pro 5,1 in good shape delivered for around 500 USD off of eBay .

    There are some single socket processor tray on sale at eBay like this one, for a genuine 5,1 Mac Pro http://www.ebay.com/itm/Mac-Pro-5-1...376?pt=LH_DefaultDomain_0&hash=item35e3542988

    You'll have to be careful in asking the seller that it has to be a 2010-2012 tray. If the tray has upgraded cpus, clarify if the seller is highly skilled in upgrading and if the temps and fan speeds are fine. There are also sellers that accept custom made cpu trays for the Mac Pro.

    If you really have a factory Mac Pro 2010-12 model , then a compatible CPU Tray bought from eBay must have a SMC version of 1.39f11 or your fans will go haywire . Ask the seller to verify this . These Trays go for a serious premium , compared to the factory Mac Pro 2009 1.39f5 ones .

    In a Nehalem Mac Pro , the system and Tray SMC versions MUST match . You can discover the versions in your system profile . Or maybe with your ears, if they don't match ;)

    It's definitely a 2010 that I have. I bought it from Apple.

    I started having odd behavior with USB, then with video and HD sustained transfers. I disassembled to find a liquid like substance on the tray, possibly from a leaky cap or something.

    Post some close up pictures of the leakage, please . I have noticed in the past some clear sticky liquid on the PCB of these old Trays . It is from the CPU heatsink's TIM adhesive denaturing and is probably harmless . I have not noticed any short circuiting issues yet . This might be what your liquid is .

    Do you have a copy of Bresink Hardware Monitor ? Let's discover if it's a thermal issue .

    There's a link to a pic before I cleaned the dust, which didn't want to remove from the liquid b/c it was stuck.

    I figured it's possibly coming from the HSF, but I replaced the original TIM with Arctic Silver long ago and I've never seen it produce anything like that, especially with the small quantity used.

    Regarding temps, it's not doing anything stressful and having issues even in the 40's C range.

    I should mention that there's nothing at all on the other side of the HSF. It's totally clean.

    this is normal. all 4,1/5,1 I have seen are like this. it's coming from the rubber thermal pad which makes contact between the heatspreader and the VRM components. I don't think that this will lead to an unstable system...

    Hrm, back to the drawing board then..

    Northbridge chip seems to stick at 56C, heatsink 47C.

    Your Arctic Silver thermal paste on your CPU is not causing that wet area on your PCB . It is the tacky long and narrow TIM pad on one side of the bottom of the heatsink denaturing . That is why that spill is not on the other side of the heatsink (it's too far away) . That wet area is larger than most I've seen , though .

    ----------

    What are those figures at load, after one hour ?

    NB chip is a critical point of failure in nehalem cMP .

    The difference in temps between the NB chip and heatsink seem normal .

    It wasn't a huge load but it's not crashing under a huge load either. It's more odd things, like doing a backup or just leaving the machine unattended overnight. It'll seize up over night.
