this is where the dba is in
The Thermaltake Silent Boost is a significantly larger than the Ajigo and, at roughly $25, is also a fair bit more expensive than the $10 effective cost of the stock heatsink / fan. With a maximum dBA of only 21, however, the Silent Boost is much quieter than the low-end 28 dBA that cooler specifies, to say nothing of its potential 48 dBA rating.
