I have bought there a little because I had 450 Athlon already functional with the 4th heart and I was content.Le worries is that on this one after the 4th heart activated his temperature rose more 75 ° even with a TX3 EVO. With other PCs at home (even made 4) with a water cooling (cooler master 120V) I have exchanged and always too hot ...... So these two control ventilos because not afford to buy Jetflo now. I put them in push-pull on the water, with a small Rhéobus. I have to turn them thoroughly but they are not noisy (well-connected to the CPU fan connector) and this time victory, the processor does not pass the 62 °.
These are not the best ventilos the world, but in this price range though!
