Testing On AMD:

To test the heatsinks I used a volt-modded ABIT KT7A-RAID with a 1.4GHz Athlon (TBird). The board was placed on a workbench to run the tests so I could control the ambient temperature (which would be impossible inside a PC case). The tests were run at two speeds:

• 1,400 MHz @ 1.73v (MBM reported 1.76v)

• 1,600 MHz @ 2.04v (MBM reported 2.07v)

As to avoid confusion, I am only reporting one temp reading which is from a temp probe that I glued to the bottom of the CPU. The probe I affixed is placed DIRECTLY under the CPU core. You can see the spot of arctic silver where the motherboard probe touches, which is quite off-center and doesn't report as accurate temperatures.

Wpcredit was used to enable the HLT command for true CPU idling. Once the system booted up it would sit idle until the temp stopped changing. Then to put it under load I used Prime95 and ran it until the temp again stabilized (or system crashed, in some cases). Generally once it starts running the 8K FFT tests the temperature will peak.

The ambient temperature was kept at 24.5°C +/- 1°C.

Idle temps were all very close, they ranged from 25°C - 27°C @ 1.4GHz and 30°C - 33°C @ 1.6GHz.

Testing On Intel:

For Intel testing I used a volt-modded ABIT IT7-MAX with a 2.0A GHz P4. The board was placed on a workbench to run the tests so I could control the ambient temperature (which would be impossible inside a PC case). The tests were run at two speeds:

• 2,000 MHz @ 1.52v

• 2,670 MHz @ 1.74v

The IT7-MAX supports direct-die temperature reading, so I used that for the highest accuracy. Keep in mind that the on-die temps are somewhat higher than what an external probe would read.

Again, the ambient temperature was kept at 24.5°C +/- 1°C.

Conclusions:

The GlobalWin CAK4-86 gives excellent performance, beating out the crowd by a noticeable amount. However with the Delta fan it is extremely loud, which could be a factor depending on how quiet or loud you like your rig. Also remember these temperatures were performed on an open bench, a case with high air flow could lower the temps even more. Your results may vary depending on the MHz & Voltage used.

My only complain would have to be the shroud & the AMD clip. I think notching the other side of the shroud would be nice so that it wouldn't matter which way you put it on. Also the AMD clip wasn't exactly the most friendly to mount, nor did it clip on all 3 tabs, which is something I would of like to have seen for a heatsink this size to make sure it is secure.
