The box includes a detailed set of instructions, the cooler itself, and a very attractive expansion slot fan speed controller which is definitely not something I would normally expect at this cooler’s under $20 price point.
The fan controller attaches to the motherboard’s CPU fan header, but it doesn’t receive power from it. This is strictly so that the motherboard can read the RPM of the fan. The HSF itself attaches to the fan speed controller, (or you can attach it directly to the fan header if you don’t plan to use the fan speed controller.) The fan controller, (and the HSF if it’s connected) get power from a 4-pin molex connector.
The TR2-M2’s fan is a T.M.D., or Tip-Magnetic Driving fan. That means that rather than having a large center motor like most fans, a side effect of which is a large “dead spot” in the center of the HSF where air doesn’t circulate, the TMD only has a small spindle to keep the fan in place. Its metal fins are powered around the edge of the fan magnetically. You may recall that TMD fans suffered some growing pains, but the bugs seem to have been worked out. I didn’t have any failure problems with the TMD on this HSF. The fan is a 74mm unit with selectable speed between 3000 and 5600rpm.
