Case Modders Australia takes a look at the newest offering from Thermalright. Go check out their review of the Thermalright CB-6L HSF. here's a snip:
"The Aluminium part of the heatsink is made using the common extrusion method, but Thermalright doesn't say what the thermal resistance of the heatsink is rated at. Looking a little closer, you are immediately bought back to reality when you realize that this is probably one of the lowest profile heatsinks you have ever come across. My second thoughts were "how the hell is this thing gonna cool my tbird??..." Well Thermaltake rate the CB-6L "for AMD Duron/Thunderbird(Socket A) 1Ghz & up."
