I'm running a 2100 overclocked to 2158mhz at 1.75 volts. The silent boost runs at about 2500 rpm but it isn't quite as noisy as the smartfan 2 at 2200. I'm a little dissappointed in the temps as the 1700 (clocked at 1800mhz @ 1.65 volts) was running at 36 and about 41 under load. The system temp was 28 at idle and 29 under load. The ambient temp is about 75 F (23-24 C). Overall, the boost did a pretty good job but it doesn't give you the flexibility of an SLK 800 and adjustable fan. At 5500 rpm, the Smartfan 2/AX-7 combo does very well (didn't test it last night but I remember getting very good results) and will beat the boost. If you want a fairly quiet combo that doesn't require maintenance, the silent boost is a good choice. But, if you want the flexibility of being able to get maximum cooling when you need it (such as at a lan party where noise isn't a factor), a thermalright heat sink/adjustable fan will do the job better.
