Today we have two coolers for that nuclear reactor you call a processor from a well known company known for producing some of the best heat sinks. Thermaltake is that company and the V1 and DuOrb are the CPU coolers. We first looked at the V1 back in November of 2007 and found it to perform well on a dual-core CPU. It is back again to flex its cooling muscles on our quad-core setup along with one of Thermaltake’s newest coolers, the DuOrb CPU edition. If you feel a bit of Déjà vu coming on it’s because Thermaltake first used this design as a VGA cooler and our testing found it to perform quite well on our 8800GT at the time. How well this design will work on a CPU pumping out a lot more heat remains to be seen.
he site concludes the DuOrb represents good value, it's not the performance king but it has a good price/performance ratio and keeps the motherboard cool too. The ThermalTake V1 is a bit more expensive and therefore the reviewer recommends you buy a better performing cooler like the Noctua NH-U12P.
