NeRP's AmigaOne Cooling Page

Here is my cooling solution thus far:

That heatsink/fan is from Swiftech.

The instructions that come with the heatsink are straight forward and simple, and are even available on their website as a pdf.

The model that I'm using is the MCX159-A.
 

You may remember the above picture of my cpu from a previous article. By consulting this, I know my CPU version requires 1.84 to run correctly. Be *sure* you identify your CPU before upping vcore! Some A1's come with CPUs that run at 1.6 vcore and don't require any adjustment.

Also, do *not* up your vcore if you are still using the ThermalTake Crystal Orb (the stock heatsink). You *will* end up with a dead G4 module.



I slowly ramped up my vcore from it's default 1.59. Using a laser-infared thermometer I measured the temperature of the heatsink from literally every possible angle in order to measure heat. All temps were taken with dnetc working cracking keys. Here is the data I got:

At 1.59 vcore and 800mhz it ran at 34.7C
At 1.79 vcore and 800mhz it ran at 39.4C
At 1.84 vcore and 800mhz it ran at 40.6C
At 1.84 vcore and 933mhz it ran at 43.6C



Room temperature at time of testing was 22C I measured this by taking temperature off my aluminum case side door which was sitting across the room. Time of day was evening. Based off this I assume that the aluminum case cover was very close to room ambient temperature and was not heated by any outside source like the sun.

According to Adam Kowalczyk, the junction temperature should be well below 65C for my chip. By his calculations the copper slug would have to get to about the temperature of 55C before the core was reaching a junction temperature of 65C
