I read the FAQ after I bought it. :-(
The box should have said it has a limitation. I think I am ok because I have an Antec One case which has a top case fan and my motherboard temps from th4e BIOS seem ok. I'm trying to set up Linux to read the temperatures but I'm having problems. |

WOW, someone actually read the fine print in the CPU Support list!!  bjlockie, good for you, most people don't even notice that. It is important when using an FX-8000 or FX-9000 series CPU. The reason for that is the CPU VRM heatsink needs air flow over it to keep it cool with the high power usage FX-8000 or FX-9000 series processors. Here's an example of how this works:  But don't think you must use a top down blowing design CPU cooler. It is possible to have enough air flow over the VRM heatsink with the fans in your PC case. Fans mounted in the top and/or the top rear location of your case will provide some air flow over that heatsink. It may be also possible to mount a small (80mm) fan that pushes air across that heatsink. |

The best I've come across is the Noctua NH-C14S. However, it's not very good if you plan to heavily overclock your CPU, since it's only recommended for max 140W TDP. I think this might be a common problem with these type of coolers.

The Gammaxx 300 is not a top down cooler it is what is known as a tower cooler. A top down cooler has the fan oriented parallel to the motherboard. Google search "Top down cooler" and you will be greeted with a broad array of coolers. The best ones for the purpose you need are the type that look like a tower cooler that has been bent 90 degrees and now blows directly onto the motherboard and CPU.
