For our temperature tests we loaded the system for 10 minutes using Prime 95 and recorded the CPU temperature using CPUID HWMonitor. We then restarted the system and left it idling at the desktop for 10 minutes before recording temperatures. The temperatures recorded are based on an ambient temperature of 20 degrees C.
The thermal performance of the Silver Arrow falls slightly behind that of the Noctua NH-D14 and Phanteks PH-TC14PE in both the stock and overclocked tests. However, it's an impressive feat to achieve a stable overclock at this level with any cooler and the temperatures are only a couple of degrees behind.
Id much rather have the Corsair H100 or H110. These take up too much space around the CPU socket.
“they will both be completely inaudible when used inside a quality case.”
No, just no. Neither of them will ever be completely inaudible
