Add a little thermal tape and a thermal probe, and the fan will keep an eye on things itself.  According to the documentation, with the heatsink at 20 degrees C it will run at 1300 RPM, and when the heatsink gets up to 55 degrees C, the fan will be running at 6000 RPM.  Just watch where you put the thermal sensor; it should be on the heatsink itself, but NOT touching the heat spreader on the P4 CPU, and most DEFINITELY should not be placed in between them.  And while it might seem like a good idea to use that beautiful Thermaltake lettering on the bottom as a target for the sensor, it's not.  Because the heatsink is uneven there, you might not get a steady, accurate reading.

Placement is pretty critical; the thermal tape used to secure the sensor is thin, but it DOES have a thickness.  You could end up with some of the tape holding the heatsink off of the CPU spreader which might be a bad thing.  Best idea would be to spread the thermal grease, then just push the HSF unit down.  This way, you get an idea of where the square of the CPU's heat spreader will be, and can put the sensor just outside it.

This is complicated!

Luckily, Thermaltake didn't skimp in the documentation department either, since I hate it when companies throw all of the lovely features they can fit into something, and then the instructions pretty much say "1. Switch on  2. Use"

Thermaltake's instruction pamphlet is simple, but very informative, giving a diagram of each step of the installation and configuration (CONFIGURE a FAN?  YES!)  There's even a 2 step removal process included.

So, is there a downside to this cooler from heaven?  Well, there may be, since we haven't hit the benchmarks yet, and don't know how well all of this actually WORKS.  But there is one definite downside, and that's the weight.  Even though retail P4 heatsinks are fairly heavy in their own right, they're made from lightweight aluminum.  Copper is a bit heavier.  

In the box

Actually, it's not a box, it's clear to a plastic blister-pack-case thing.  But before we go to the tests, we'll quickly go over what's in the package:

1 heatsink-fan unit (duh!)
1 instruction sheet
1 jumper (don't loose it!)
1 strip thermal tape
1 pack thermal grease compound
1 thermal sensor and wire
1 control-dial and wire
1 power adapter
2 retention brackets
1 specification sheet

The power adapter takes a bit of explanation.  It uses a special plug into the fan, and one plug leading to a Molex connector, and one plug to the motherboard for fan RPM monitoring.  I suppose if the motherboard is not providing enough power to run the fan this sort of configuration might be useful, but without an available fan plug on the board, the RPM monitoring feature is useless.

The specification sheet is nice, because it tells you exactly how the unit is supposed to be operating, and even includes a couple of graphs, which are below.
