SilverStone Technology AR09-115XP 2U Rackmount Server/Small Form Factor Intel CPU Cooler with Push Pin Design

The SilverStone Technology AR09-115XP 2U Rackmount Server Small Form Factor Intel CPU Cooler has received mixed feedback from users. Many customers found it to be effective in keeping their CPUs cool, particularly in 2U form factor servers and high-end workstations. One user mentioned that it kept their 65W i7-4790s @ 4.0GHz within safe temperatures even under heavy load. However, the stock fan was often criticized for being loud, with one user recommending the purchase of a quieter Noctua fan to replace it. Some customers also reported that despite the high fan speed, they did not feel much air flowing through the heatsink, leading to dissatisfaction with the product's cooling performance. One user mentioned that after replacing the stock fan with a Noctua fan, the cooler became whisper quiet while still maintaining safe temperatures. It was also noted that in certain cases, the cooler did not provide a noticeable improvement in CPU temperature compared to the stock Intel cooler, possibly due to the lack of proper front-to-back airflow in the case. In summary, the SilverStone AR09-115XP received appreciation for its 2U form factor and solid build quality, along with its ability to keep certain CPU models cool. However, the loud stock fan and potentially limited airflow performance were seen as notable drawbacks by some users.
