For all you that did the MacPro5,1 Dual CPU upgrade to the 5690 what are your CPU A + B and PCH temperatures?

I upgraded my CPU's and it was running a bit warm around 84 - 88C and the PCH was quite a bit hotter according to both iStats and HWMonitor. I redid the thermal paste today after giving the CPUs and the Heatsinks a good clean with the AS cleaning kit. Put it back under a Geekbench stress test again and the temps are the same. The before and after test were conducted with the fans running at the stock speed.

Intel lists the maximum tempeture is 78.5C so I am quite a bit above that. The only way I can get it to come down currently is to run all fans but the PSU + PCI one at about 1300rpms.

Is running at those higher temps when under load okay? Thanks.

I can let you know my temps on Monday. I'm currently hammering my 5690's all day long in a very hot room so this should give an extreme top end temp range. I'm also running fans on the medium setting in iStat so ill drop that back to default and let you know.

Cheers.

Thanks for checking it out. I did some more searching and I think the number listed on the Intel ARK site is maximum temperature for the CAP not the CPU Core itself. I ran the pmset -g thermal and didn't see any warning.

Ok cool. Yes the thermal tests are the thing to do. If that's clear you're all good.

There is no Tcase temperature avail on the cMP. And since the Tdiode temperature usually quite a bit higher than the Tcase temperature, 85C should be well within the Intel limit.

My W3690's Tcase Max is 10C lower than your X5690. And it can run at 85C Tdiode 24/7, with no thermal warning in the log.

All,

Perhaps answered so apologies if it was in a prior post. Have 2010 Mac 5,1 dual quad core 2.4 E5620 Intel CPUs. Looking to upgrade them to 3.33 X5680 processors instead. Seen some videos showing delided specific Apple "versions" of the CPU that are basically held in place by the huge heatsinks and a small square retainer around the chip... The pics in the starting posts on this thread show a retainer clip and the more standard CPU chips with their lids in place.

What I'm trying to figure out is for this model if I'm going to run into the height problem if the Apple ones being delided, and replacements having their full covers on. If both have lids, it shouldn't be an issue.. If the 2.4s did not have lids, how do I account for the different in height? Can I just leave those square risers off and mount the heat seats directly to the tops of the 5680s with their lids??

Appreciate any thoughts.. Thanks!

Jay S.

I believe all of the 2010 5,1 machines used stock, lidded processors. The 2009, 4,1 dual-processor machines used de-lidded processors necessitating some workarounds if you are upgrading the CPUs. That accounts for the different photos you've seen. On your machine, this should be a straight swap without the need for washers/spacers/risers provided the X5680s you are putting in have not been de-lidded

Much appreciated.. Didn't want to undo the tower heat sinks and have to redo thermal if I didn't have to. I'm hoping that's the case.. Not too many retail 5680s out there any more. OWC says their's are new.. must have a stock pile.. They just don't sell the 5680s.. only use them for their turn key upgrade solution, but at $1350 that's a lot of labor cost as well.

You have to remove the heat sinks and redo the thermal paste for all processor upgrades, regardless of whether they are lidded or not.

Totally understand.. Was trying to avoid having to do it just to find out if they (Apple) delided the original Intel CPU or not.. Just trying to be a step ahead if possible.

I suspect OWC bought a bunch of these back when they were current. Given the prices they charge for turnkey, I'm not surprised they still have quite a stock. I usually have a strong preference for new parts, but given the scarcity of new stock for these processors and the massive price difference between new and used, you might want to consider buying used CPUs from eBay. There are a number of vendors that specialize in cannibalizing server parts from businesses offloading their old machines. You can pick up a used pair of x5680s right now for $250 US. Now is also a good time to stock up on used DDR3 1333 if you'd like more RAM. Your new processors will be able to utilize faster memory than the E5620s you currently have (although, you'll be pressed to notice the difference on day-to-day tasks).

Brain surgery :) performed yesterday with complete success. Dual hex core 3.33 (x5680s - picked up the matched pair Ebay deal at $250 - used but 30 day warranty - very very clean when they arrived) running smooth as silk.. Used Arctic 5 Silver (pea method) and actually running 5 to 7 degrees (centigrade) cooler at idle than the 2.4 chips. have to say I was NOT impressed with what I saw when I pulled the heat sinks away from the chips.. there was thermal paste everywhere and these came straight from Apple. Didn't look like the chip coverage was very even or perhaps even adequate with most of the paste out on the sides. :-( Very happy even when pushing to chips doing a rendering and export on 4K video.. Max CPU A was getting up to was around 70 to 75 degrees Celsius..

Brings up a question. Arctic says break-in on the paste could be a couple of hundred hours (so may go lower in run temps).. BUT does the paste's effectiveness break down over time? Is this something to repeat (cleaning and putting down new thermal paste) say on a yearly basis?

Again thanks for the help.. Benchmarks out of Geekbench 3 are great compared to the 2.4 quads..

Glad it went well!

I performed similar surgery last month by going from a quad 2.93 to a hex 3.46. With the new application of paste, I'm seeing a reduction in idle temperature by ~15 degrees F. I don't believe paste reapplication is something you need to perform annually, but I defer to others here more experienced in such matters. I suspect the large temperature differences we saw were the result of a poor application of paste from the factory.

Don't expect any significant different after than 200 hours. What you get now most likely is the final cooling ability in the next few years.

And in my experence, no, you don't have to do this every year. As long as the temperature / fan speed is normal, you don't have to touch it. They usually last for years.

Thanks. I only mentioned it because it was a part of Arctic Silver 5 description.. I may not see a difference but will keep an eye out anyway.. I really pushed the heck out of the processors yesterday, for an extended period and CPU A stayed solid in the 79 - 81 degree Celsius range during the operation and dropped immediately back down to the idling temps I mentioned. CPU B ran about 7 to 10 degrees lower.. This was a REAL push.. 8 active and concurrent exports of hundreds of images in LR and re-render a 4K video.. Not a normal work flow for me but just wanted to push it to watch temps and test chips..

So I made some time today to Upgrade my Mac Pro 5.1 (2010) from 8 cores (2 x 2.4 GHz Quad-Core Intel Xeon) to 12. Thanks to @bokkow I managed to get my hands on 2 x 3,33 GHz 6-Core Intel Xeon (X5680).

The switch was relatively easy, although I did have an issue getting one of the heatsinks off. The screw loosened but never seemed to want to let go. I tightened the remaining screws back up and proceeded to unscrew that particular screw first and it came loose.

I picked up some Gelid Solutions GC-Extreme thermal paste, which I'd read was quite viscous. But I got around this heating it up 'au bain-marie'.

My CPU temps have maybe gone up by about a degree when idling, so all in all that strikes me as a successful upgrade. CPUs are sitting at around 45 and 36 degrees celsius.

Hello

I would like to do the same CPU upgrade with my Mid2010 Mac with two 2,4GHZ. In a lot of threads i could read that i should use CPUs without the heat-spreaders. Now i found your post. Do you use the CPUs with the heat spreaders? - and if so what did you do to prevent the board from damage?

Cheers-Ralf

(Integrated) Heat Spreader (IHS) is different than Heat Sink. If your MP is a 5,1 2010, you do not need do remove IHS from the CPUs. Of course, you do have to remove the Heat Sinks to access and swap the CPUs.

It is the 4,1 2009 dual CPU MPs that used CPUs without IHS.

My Mac has this Specs:
Modell-ID: MacPro5,1
CPU-Type: Quad-Core Intel Xeon
CPU-Speed: 2,4 GHz
CPU: 2
CPU-Cores: 8

It's hard to find the perfect info for the right solution. I know the difference between heat spreader and heat sink but i don't know that there is a difference between the 4.1 and 5.1 modell when it comes to CPUs with or without the heat spreaders. Here (on ebay) they sell sets with and without 24 brass heat sink washer screws to equalize the hight-difference:
http://www.ebay.com/sch/m.html_ssn=...1&_from=R40&_sacat=0&_nkw=mac+pro+5.1&_sop=15

Do you have a recommendation where to buy the CPU (i'm in HH-Germany) and what do you think today about your own upgrade-speed-price relation?

If you have a real 5,1, you don't need washers. If you bought it new from Apple, you have a real 5,1. If you bought it used recently, check the serial number to be sure you don't have a 4,1 that's been flashed to 5,1.

With a real 5,1, you don't need anything other than a pair of stock Xeon X5680s or 90s, the right hex wrench, and thermal paste and cleaner to do the job. You will love the performance boost, especially if you work with multi-threaded apps. Shop Ebay for used CPUs.

His I'm new to the forum and was just wondering if I can order any intel xeon cpu for my 2010 mac pro? I see a lot on ebay that say pulled from server? Does the pc ones work or does mac have something wrote to then by firmware or eccentric or Something?

I have a 2010 mac pro with a 250 gb ssd?3 2tb hdds? 5770 gpu, 2 cpu's for 8 cores and want to upgrade it to 12 core. I don't see any mac specific cpus, as long as the cpu is a listed compatible cpu it will work?

Hello "Ya Boi"

You need this:

The links are only examples. I think it should be possible to get a better price.

Ok, a friend of mine has two of the 6bcore matching intel chips that are 2.93 ghz for 12 cores he said he would give them to me for free and install them. He bought the 3.3 ghz ones and no longer needs these. Was hoping I could use them because he was willing to give them to me and install it for! Lol
