TWIN TURBO Notes :
Arctic Cooling Adjusted the Twin Turbo for most of today's video cards,
but one flaw we found is during installation you attch the fan power cord
to the connector found on the video card itself, but sometimes you will
need to adjust the fan speed.
When you use Nvidia cards it's quite simple , but using ATI cards,
like the recent HD 4850 and 4870 which are not supported by most
utilities today, this is a problem.
The twin turbo fan wasnt working at all when installed , or working very
slow, something that can be solved using a profile for OC under the
overdrive menu inside the drivers, but this is not the perfect solution.
Thw Twin Turbo was checked using 2 situations -
the first one is 1500rpm , and the second one is 1050rpm, performance
and silence mode.
Thermalright V2 Notes :
The V2 comes without fans , which required us to use 2 80mm fans,
first one was a Nexus fan, 1500rpm and 20.2CFM, the other one
from CoolerMaster, 2600rpm, and 34CFM.
once again , 2 modes - performance and silence.
One more thing is the lack of heatsinks for the memory chips and mosfets
of the HD 4850, which required as to use the Accelero heatsinks.
