Hi Everyone!

I'm new on this Upgrade Issue and I just Upgraded my Mac Pro 4.1>5.1 (Early 2009) to 2 X 3,46 GHz 6-Core Intel Xeon

I Just want to know what is the regular temperature of these Processors, as I've installed them and I'm afraid they could get too hot and fried!

I have a software called "iStat Menus", and the temperatures this software reports are

CPU 1 Temperature - Oscillates between 62º & 73º
CPU 2 Temperature - Oscillates between 52º & 63º

Please help on this!

Never had any thermal issues on my 3.46
Applied some Gelid GC Extreme thermal compound and it's cool and happy.

Is that under load or at idle?
What is the ambient temperature reading in iStat?
And is that reported in iStat as the 'tdiode' temp or 'to proc hot' as one counts up and the other down!
Also, what are the heatsink temperatures reported as in iStat?

You need to run stress test to determine if the cooling system is working properly.

Run Prime95, torture test, make sure it stress all 24 threads.

Then monitor in iStat. You should see the Tdiode temperature keep increasing. And then the fan start to spin up more once reach around 80C, then should keep the CPU diode just around 85C, but should not go beyond 90C. And once you can see the temperature stabilised (like my screen capture below), then you can now determine if your system has normal cooling.

P.S. I modded my fan profile a bit (as per the screen capture), and I use liquid metal rather than normal thermal paste. So, it run cooler than normal setting. But for normal cMP, with native fan profile, the target CPU temperature should be around 85C.

If the CPU temperature go beyond 90C during the test, stop the test. No need to panic or hard shutdown the Mac. The CPU can thermal throttle itself. But you better stop the test, create a better fan profile, and then try again. Apple never ever ship a 5,1 with dual 130W CPU. So, it's hard to tell if the native fan profile is good enough for dual X5690.

Also, if the CPU temperature increase rapidly (e.g. reach 80C in few seconds), this is also a sign that the cooling system isn't quite working properly (for info, it usually cost me more than 3 min to reach that stabilise temperature). May be thermal paste, may be heatsink too loose, may be bad thermal paste application, may be even the solder under the CPU lid has crack. But since you have two CPU, you should able easily tell if one of them looks very wrong.

Last but not least, CPU A should be around 10C warmer than CPU B, that's normal.

Man!, I had someone to do it for me... as I'm so bad with Electronic things... but still I was reading around and I'm kind of afraid to loose so much money by not taking care!... He did put some of that Thermal Paste, from "Hainziye"

Well... We'll see! ;-(

Man!..

You managed to put me down with 3 "Simple" questions!...

I dont know a shº*/ about where to get that info... fr me was only clear the temperature... but here I put a picture from how it looks... maybe you can find out and help me with that!

Hola!

master thanx a lot for your time and dedication!.. I apreciate it!

Well. I did the test and as you described, the both went up to 89º, and then the CPU went down to 77, but the B one stys up on 88/89º

Please check the screenshot and you will see the results... Maybe you get an Idea of what shall I do!?

Once again Thanx!

But...
What are the normal temperatures on those X5690 CPUs?
Do you think I shall put the Thermal Paste Again?, which one would that be(Liquid Metal?)
How can I change my Fan profile?

Gosh!... I think I'm getting an specialist... I mean, I never had to do none of these things! ;-)

I’d say your temps are fine and I wouldn’t worry about doing anything further. Just enjoy your computer :)

Anything below 100C is normal temperature for X5690.

Are you using delidded CPU? If yes, you may tighten the heatsink a bit more. But if you use normal CPU, or you have no idea if that's delidded, do NOT touch it. Tighten the heatsink with lidded CPU can damage socket, which effectively kill the whole CPU tray.

And you better forget about liquid metal, it's not for normal users.

For fan profile, you can use MacsFanControl (a free software).

Set

Booster A base on CPU A diode, min 60, max 99

Booster B base on CPU B diode, min 60, max 99

Intake base on CPU A diode, min 60, max 99

Exhaust base on CPU B diode, min 60, max 99

These should be a very safe setting.

Hi!

Well, yes is de-lidded(without the metal), and on the meanwhile I found that I had to tight a bit more those Heat heat-sinkers, and I did!...

Temperatures stays around there always, Between 66 and 75 by now on the CPU-A - Tdiode

Just one last question... Youve wrote a "Set", I guess for the "MacsFanControl", but I really didn't understand if is so!

Please check the Pic. and see how does my setup looks...(default)

What shall I do with the RPM Speed?

Those settings are for MacsFanControl, not smcFanControl.
