Egrimm,
There are lots of reasons why Thermaltake products are piss-poor at times.
Lets start with the Super/Chrome Orb. Crap base quality, warped bases, uneven ocntacts with AMD pads, the list goes on and on, in addition to poor performance.
Copper Chrome orb: Uneven matching of copper and aluminum portions. They appear to be manufactuered separately, the put together. Uneven bases.
Dragon Orbs: Upper "fan" area has no cooling effect. Same potential gaps between copper and aluminum portions. Base quality is better however.
Volcano 5: varying base quality... leaves quite a bit to be desired, but still leaves some qc issues to be desired
Volcano 6CU/CU+: Same copper-aluminum issue. I know that cost is the driving reason behind not forging the copper and aluminum at the same time. So for cost cutting measures, the quality of product suffers.
Now the infamous blue orb: Everyone likes this product, however, it really isn't that good. Manufactuered in 2 pieces that do not have good thermal contact between each other, as well as extremely poor base quality.
If you're looking for a mild o/c or just your basic heatsink, thermaltake products are fine. HOwever, if you are looking for high end, it is highly suggested to look elsewhere.
