Lately, a lot of "tricks" have shown up in the higher-end CPU coolers on the market.  There's the old copper trick, which is a better heat conductor than aluminum.  There's the thin-fin trick, which uses thin, machined fins (a LOT of them) to give greater surface area for heat dissipation. There's the adjustable fan trick to keep noise down if the CPU isn't running too hot.  And then there's the self-adjusting fan, that spins faster or slower, depending on how hot the CPU or heatsink is. All good ideas in their own right, and all, to some degree, effective in reducing temperature, weight, or noise.  But Thermaltake had another idea.

Throw it all into ONE heatsink-fan unit, and throw THAT into one box.  Interesting yet?

Say WHAT??  

That's right, the P4 Spark7 is, to some degree, all of the above ideas fused together (some more than others though).  There are 50 or so copper fins welded to the thick bottom plate.  Careful putting your fingers on there, because if they slip, you might get cut, just like on a radiator.  But be careful while installing it, and you'll have about as much heat-dissipating surface area as you could possibly squeeze out of a block of copper.

Outside the border of the fan, the top ends of the fins are folded over, to keep air moving between the fins, rather than prematurely escaping through the top.  However, they did NOT do this at the bottom edge of the fins; air can still get out there, though it's not going to get far before hitting the motherboard and the plastic HSF retainer.


The bottom, seen above, is pretty much unmachined, except for a beautiful inscription of Thermaltake's website.  It's very nicely done, but once this guy is installed, you'll never see it again. 

Ok, so far...

..and it gets even better.  The other hot item on this unit is the 6000 RPM fan.  Besides being 70 mm, and a nice orange color that matches well with the copper (and having a sweet Thermaltake logo finger-guard), it runs at 6000 RPM and pushes 49.17 CFM of air...when you want it to.

That's the most simplistic setup, of course.  Another option is attaching this control dial to the unit and running it to the outside of the case, thereby giving you manual control of the fan's rotational speed, from 1300 RPM to 6000 RPM.  This is handy if you only want to turn the fan up when the system is under heavy load, but it can be a pain sometimes...especially if you forget to turn it up one day.  Hence the third option:
