With the increasing core frequency of
the videocard, people have enjoyed the advantages of the
high performance of the videocard, but also facing some
heat problems; now the power of the videocard with HMA have
exceeded 70W, so there is more heat to shift. In order to
solve this heat problem, TTCC have developed a new videocard
cooling system. The system can cool your video card, the
temperature of the cold-end can be decreased to minus10℃.
The videocard cooling system is an active cooling system,
which came into the market firstly; it has applied the high-tech
of semiconductor. Compared to the normal heat sinks and
heat dissipating system, it has several advantages:
1. High heat dissipating efficiency: the normal heat dissipating
system dissipates the heat passively, while the videocard
cooling system can actively absorb plenty of heat, which
is produced by the videocard's core when it operates; so
the temperature will not get so high, and the life of the
chip can be prolonged.
2 Great potential for development: it is easily to improve
the refrigeration power by improving the power of the TE
modules, now the videocard cooling system can solve the
heat problem of the CPU and videocard.
3 Save space: in order to improve the heat dissipating
capacity, the size of the traditional heat sinks and fans
are getting larger and larger, covered so much space; while
the videocard cooling system do not need big heat sinks,
so it saves the space.
Comparison between the videocard cooling system and traditional
heat dissipating system (heat sinks and fans):
