The low-noise AK-872 is a high performance 8mm heatpipe cooler for AMD Athlon 64, 64x2 dual core, FX, Sempron and Opteron. Evolutionary nickel coated heatpipe technology is utilized a new development in CPU cooling. The copper base provides maximum heat absorption and in conjunction with the heatpipes rapid heat transfer. The fine-fin aluminum heatsink guarantees efficient heat dissipation. 9cm lo-noise fan ensures optimized performance. 2 x 3 point location clips provides safe retention.
Advantages: Very cool, easy to install Disadvantages: copper on the cpu side far from mirror ( needs a polish )
...Test system:
processor - AMD Athlon FX62 (2 x 2800 MHz / 125W TDP)
motherboard - ASUS M2N32 DeLuxe Wireles Edition (passive cooling system with HeatPipe)
Cooler is very easy to install just one lever.
More experienced users will probably remove thermal compound and polish the surface of the cooler ( it is far from being a mirror ) and then apply high quality thermal compound.
This will give You another 1-2 C less and faster cooling down after stress.
all tests were done using Zalman STG 1 ( high quality thermal compound )
Temperature readings after 60 minutes in idle:
AkasaAK-876 37
Arctic Cooling 64PRO 38
Scythe Katana II 39
Temperature readings after 60 minutes in 100% load:
AkasaAK-876 56
Arctic Cooling 64PRO 58
Scythe Katana II 61

Advantages: Non-conducting, easily applicable, very good cooling Disadvantages: tube is rather small, for approx 10 applications
...When buying a CPU or Graphics card, most manufacturers have already installed or included a heatsink + thermal conducting paste or pad with the product.
This thermal conducting paste is usually made of silicone, either grey or white and has the effect of filling the gaps between the heatsink and the chip, to improve heat transfer from one surface to the other.
So you are wondering why companies like Akasa produce heatsink paste when something is already included. The answer is that the Akasa product (TC 5022 Pro) performs significantly better than the standard one and holds its ground against other pastes (like Arctic Silver).
The paste comes in a small tube and is pretty expensive. The compound is made of silicone, but has the benefit that it is easily applied on surfaces, as well as performing very good, even when not applying too...
