Zaward Twin Towers



Processor AMD AM2 6000+ Dual Core
Motherboard Biostar TA690G AM2
RAM Corsair XMS2 6400 2GB (2x1GB)
HDD Maxtor DiamondMax 20 80GB SATA
Power supply Jeantech Storm 700w
Graphics card Onboard – ATI Xpress 1250 series


All of the testing is carried out outside of a computer case. As with every test, we use a thin layer of Arctic Silver 5 between the chipset and the cooler for comparable results. Ambient temperature was 19C throughout.

To test we simply boot the PC up with a freshly installed copy of Windows XP, and measure temperatures using Speedfan. The temperature is taken from the motherboards own chipset temperature diode.

For idle testing, we simply let the testing rig sit doing absolutely nothing for 30 minutes and take the most representative temperature of the last 10 minutes. The same is used for the load testing, but instead of letting the PC do nothing, OCCT is used to load both cores to 100%.

In order to test the overclocking ability of the cooler, the 6000+ will get an additional 15 mhz on the front side bus, giving it an overall frequency of 3222 Mhz.

The cooler is run as designed; passively. In order to prevent any airflow from the CPU cooler, the Swiftech H20 Compact 120 water cooling kit is used.

As you can see from the results, the cooler is not as good as the Noctua NC-U6 which doesn’t bode well, as the NC-U6 is smaller, easier to mount and doesn’t conflict with the CPU cooler.

The difference isn’t massive, but there are a fair few degrees (7C at OC load) which the NC-U6 strides ahead. It seems odd that this is the case, as the size of the Twin Towers dwarfs the NC-U6, but size doesn’t matter. The NC-U6 is soldered, has two U-heatpipes (four pseudo heatpipes) and a base which doesn’t feature screwheads. These reasons alone will put the Noctua cooler in the lead. But unfortunately, the Noctua solution is actually cheaper than the Twin Towers, putting Zaward metal further behind.

Both of the coolers put the stock cooler to shame, and allow the board to overclock slightly more (an extra 5mhz) which isn’t bad considering as this mobo isn’t designed to be pushed hard, and it’s running an AMD chip. The cooling provided keeps the chipset from hitting the high 60’s which will definitely help your board last a little longer. The board won’t pass 30 minutes full load with the stock cooler on it, hence the result is missing.

For most users, you’ll witness lower temperatures due to case ventilation that’ll take some of the heat away from the aluminium fins, while keeping the cooler passive.
