Overclockers Club has just posted a review of the Thermaltake Active Memory Cooling Kit. here's a snip:
"ThermalTake is always coming up with more and more ways of keeping your system cool. Today, I will be reviewing a brand new product that they will be selling, the Active Memory Cooling Kit. This isn't your everyday memory cooling device. This cooling kit, uses ThermalTakes's old Memory Cooling Kit, plus a 40x40x20mm fan ontop. ..The fan is 40x40x20mm and runs at 5000rpm, give or take a little. The 23dBa is pretty loud, and it only blows out 5.1CFM. Maybe I can find a 7000rpm black label deleta fan to replace it with."
