-- Socket A Heatsink Round Up 1st Qtr 2002
-- Price: ~ $20-$40 USD

Next up is the from the heatsink powerhouse, ThermalTake.  Back when they first came out with the Golden Orb, they pretty much dominated the budget cooling market.  A slew of clones came out immediately afterwards, but TT still came out ahead with newer models and ideas.

They recently released their newest in their Volcano line, the Volcano 7 and 7+.  Both have similar names, but they don't look anything alike.

This is the V7, one major feature of this heatsink is the use of a temperature controlled fan.  What this means is that when the temperature rises on the heatsink, more voltage is pumped into the fan.  So it's really like an automatic rheobus, which drops the speed of the fan when your not pushing your chip.  At 25°C it runs at 2900 rpm , at 35°C 5000 RPM.  A very nice addition to a heatsink.

The fins are all aluminum in material, except the middle copper insert.  There is a black cover that goes around the unit, which is where the fan is screwed into.

TT also has gone with the thermal pad route, which we promptly removed.  Another gripe, just like GW's offering, is the small clip.  A minor annoyance, but something to think about.

Let's take a look at the Volcano 7+ now, a slightly different edition in the Volcano line.

Here are some specs on this unit:

One major difference between the V7 and V7+ is that the plus version supports both the P4 and AMD Chips.  This is accomplished by just utilizing different clips to secure the unit.

The V7+ has a large cover that hides two sides of the heatsink.  There are holes on each side so you can screw in the cover to prevent it from shifting (definitely a good idea).

This unit also utilizes the thin fin one block design.  Probably easier to manufacture and cheaper to produce it this way.  I'm not complaining, most thin fin HSFs we tested performed very well.

Again, the clip is too damn small.  I wished someone would change this somehow.

One other feature is the manual voltage switch that is positioned between the fan and the molex connector.  It lets you switch between the high, medium and low fan settings.  This means you can set it to low when you don't need the noise and high when you need the extra cooling power.  Immediate problem right off the bat, the wires are too damn short.  There is no way anyone is going to open up their case to just switch the speed down or up when they need to.  Nice idea, bad implementation.

The bottom of the unit is very smooth, couldn't feel any rough spots.
