The purchased version, XM1, the model is 2,800 rpm (revolutions XM2 3800). I acquired this fan for a raid card that was not equipped as a liability and I found a high-temperature hair (45 °) for the "cool" temperature of my house in winter (23 ° Max) . The summer that easily rises to 35 °. In anticipation, I fixed on the original radiator with other saw that I had. and which is "placed" between the fins by spreading them slightly. Placed right in front of the trial, the temperature measured on the cooler fell 10 ° .... Can be a measurement error, but I handed the probe to the same place ... It is in any case and inaudible cable is long enough and good to go to a fan socket placed on the other side of the motherboard.
Small flat, the label protecting the axis of the fan was peeled off, I took the opportunity to add a drop of oil on the shaft and carefully pick the label.
