Conclusion: I was surprised by the ability of the Thermaltake Blue Orb II CPU Cooler. Despite being somewhat louder than the Zalman heatsink, it easily trumped it in cooling ability. The slightly longer fins and perhaps larger copper core may have contributed to the success. If your case has a blue theme, this is certainly a nice addition to the setup, with a strong blue glow provided by the LEDs at the center of the heatsink.
Pros: Simple and well documented installation, Efficient cooler, Very cool blue theme, Effective for motherboard cooling
Cons: Heavy, Can be loud and offers no fan speed control options
Excerpt: Thermaltake is a well known contender in the high-end cooling market, making products that keep our overclocked CPU’s nice and cool while we attempt to drive them to the brink of oblivion and back – – often doing so in style.
Summary: The Thermaltake Blue Orb II is a great high-performance cooler. Its big heat dissipating area makes it a good cooler for overclockers who don't want to spend too much money on the heatsink.
Not only does it cool well, it is also suprising quiet when delivering its cooling performance. On top of that its massive blue anodized fins make it a nice addition to the looks of a modded case, especially if your color-theme is blue.
Pros: Great performance, Very affordable, Quiet, Supports both S939 and LGA775, Easy to install, Nice design, Blue LEDs in fan
Cons: No fan speed control, Little space near memory area on some motherboards, Does not fit ABIT AL8/AA8XE easily, Heavy
