Extreme cooling for 2013 macpro

[rueyloon]

When I'm rendering at least 3 projects in compressor, all 12 cores and 12 virtual cores are engaged. The clock speed will slowly go down until it reaches 1.4ghz.

I'm wondering if I can cool the computer down enough, will it be able to maintain a higher clock speed?

Is the heatsink clean?

You may try Macs Fan Control to set a higher fan speed to lower the CPU temperature.

If the Mac is from 2013, and still have Apple care, may be you can ask them if they can re-do the thermal paste for you.

What is your room temperature?

Apple sucks at cooling solutions.
Edit, well, marketing demands quiet devices.

Get the twelve south stand to put the nMP sideways, then point a fan at what would normally be the bottom:

Then use SMC fan control to crank up the built in nMP fan


This combo will both dramatically cool down the nMP and maintain higher GHz performance

I'm right at the equator, but when I'm working the aircon is on, I think it should be around 28 degrees C when the aircon is on.
