Hi,

can anyone tell me the normal temperatures of a Mac Pro 6,1 12-Core who is idle or on minimal work. The Mac must be run for 30 min at minimum.

I think my temp is a bit too high with around 55 °C for doing nothing (also, fan is running a bit faster by default).

From you screen capture, the problem isn't the CPU, but the GPU was warming up the thermal core, which makes the CPU can't go cooler.

I suspect you have multiple monitor connected. Therefore, GPU 2 must stay at high clock speed, which warm up the thermal core, then GPU 1, and CPU.

As you can see from your screen capture. It's the GPU draw ~65W. Most likely ~15W from GPU 1, and ~50W from GPU 2. The more power it draw, the more heat it can release.

I am not a 6,1 user. But those numbers are nothing danger to CPU / GPU. However, if you believe that's higher than normal. Or noticeably higher than before (with same ambient temperature). Then may be it's time to remove the dust.

Basically just browsing the web for two hours with a D500/hexa 3.5Ghz/64GB/2TB NVMe, fully de-dusted with compressed air this last weekend.

Only one Monitor is connected

You know that all is connected to the same heat sink? So the second GPU also warms up when it has nothing to do.
 
Looks perfectly normal.
CPU idle: 51°C (12-core, D300, Dual-DP 5K screen, 15 min after long Photoshop session, 24°C ambient)
For the same moderate tasks, my 12-core runs cooler than my previous 6-core.
As it can deliver 50% more performance at the same 130W, it's more efficient.
I might have applied a little too less thermal paste but will switch to an 8-core soon anyways.

Thanks, this will help, hope for more feedback.

27 °C ambient

Looks normal - my 12 core 2.7 with dual D700 and 64GB and 1TB is around 50-55°C.

If I run it flat out she goes up to 75°C.

When I upgraded the CPU I cleaned out the dust from the computer.

The previous CPU in this machine was 12 core 2.4ghz.

Thanks for your answer :). What is your Room temperature

My Hex was at 45 °C, an Octa user also has around 45 °C.

I need feedback from a 12-Core User

At that time, was around 29 to 30ºC.

I might have applied a little too less thermal paste but will switch to an 8-core soon anyways.

I'm seriously considering buying a E5-2673 V2, even being so relatively expensive when comparing to the E5-2667 V2.

Yeah, it's no easy decision. I finally purchased an E5-2667 V2 for 30€ whereas the E5-2673 V2 was almost 3 times that (and only available from China).
But I always wondered how noticeable the 20W difference is in real life regarding power consumption and temperatures...
Do you know what actually makes the difference? I mean both are 22 nm Ivy Bridge Xeons with the exact same clock values.

I was not happy with the temps of my first 12-Core installation, so I have repasted the CPU.

This time I use the X with small dots

Now the temps are 3–5 degrees better than before.

My Xeon E5 Quad Core D300 12Gb not doing a lot - it's about 24C here today

I don't know if this PCU runs hotter than the 12 core?

Probably due a hoover and I've not unplugged any ancillaries...

Anything stand out as needing attention here?
