Thermalright Ultra 120

Zitat

When the Tuniq Tower 120 was reviewed to begin this round of cooler tests we knew from benchmarking that it was an outstanding cooler. We really did not know at that time how good it would prove to be, as it has taken many cooler reviews to find a unit that matches or surpasses the performance of the Tuniq. The Thermalright Ultra 120 is that cooler.

The Ultra 120 is the first cooler tested that can effectively cool a stock Core 2 Duo without a fan. This works best when you use a fanless Ultra 120 in a case with a down-facing power supply cooling fan. You will also get better performance by paying careful attention to airflow and exhaust in the case design. However, this is true with any effective fanless design, and we are still impressed that the Thermalright Ultra 120 is capable of performing better without a fan than the stock Intel Retail cooler with its 80mm fan.

Of course the Thermalright HR-01 is the fanless Thermalright design and the Ultra 120, while derived from the HR-01 design, is designed to be most effective with a 120mm cooling fan. After an easy and secure installation, you will find the fan clips for the Ultra 120 will only work with a few fans. Fortunately they will work with Scythe S-Flex and Noctua fans - either of which are a good match to the Ultra 120. The problem here is that the mounted fan cannot have a closed mounting post, which is common on many fans. The Thermalright design will only work with open holes and no posts on the fan

When combined with the Scythe S-Flex SFF21F fan the Ultra 120 is a record setter. Not only does it match or surpass the excellent cooling of the Tuniq Tower 120, it also does so with lower noise at high fan speeds. That is always a winning combination. The Ultra 120 combo also matches the highest overclock seen with the test bed CPU at a stable 3.90 GHz.
