The SF775-2 stands out from the two other TTIC products because of the absence of heat pipes. It is in fact a standard 100% copper radiator. A 7 W 92-mm fan ensures ventilation, which is relatively more important when compared to the usual fans. Like with the NPH775-1, the installation system is only compatible with the T socket.
Installation
The installation system is identical to the NPH775-1.
Measures and results
The table below includes measurements with the SF775-2 from 5 to 12V.
Appraisal
This flower with very thin blades and totally made of copper, provides better performances than other flowers with copper cores and aluminum blades like the Intel Box. It is one of the best with radiators, and can compete with the XP120 and the other TTIC with columns. The offside of the coin is that it is also one of the noisiest with 66 dB(A) at 12V. This result is quite logical as the 92-mm fan spins at 4000 Rpm. Even after a strong voltage reduction to 7V, it is still unfortunately one of the noisiest. Unlike the TTIC NPH775-1, an additional fan won’t improve performances as the deltaT slope is quite flat around 12 V.
