AMD Radeon HD6990 is AMD's secondgeneration DirectX 11 graphics card flagship product, as its core, memoryfrequency and memory capacity and other hardware process of upgrading, but alsobring an influence must not be overlooked, that is, power consumption, heat andnoise. Original high-end graphics card cooling fan, cooling fan runningabilities coupled noise, seriously affecting the normal use of the player. Tosolve this problem, syscoolin launched VG69 graphics waterblock. Quiet runningwater and super original fan cooling capacity is definitely the bestalternative. Xiao Bian today its thermal testing, the outcome, let us wait andsee.
 
   
    syscooling playersto create the most suitable water-cooled VW products, while ensuring the heatin the choice of material, the same consideration for the players to saveunnecessary expenses. syscoolingVG69 using aluminum to build, as opposed topure copper cold head in terms of the manufacturing process more simple, andits price is more suitable for civilian users.


    HD6990syscoolingVG69Water Testing
    Test DescriptionThis test uses bare metal testing, which means the original fan for thegraphics card is more favorable, and for water is almost no effect. Tested at aconstant indoor temperature, the room temperature is 31 degrees Celsius. Weretested using the original fan first standby loaded with temperature, and theninstall syscoolingVG69 graphics waterblock were tested standby full load test.To ensure the accuracy of the data buffer start standby temperature is thetemperature after 10 minutes, full load test for 20 minutes pager temperature.

Standby test temperature
    These test shotsseen in the use of original fan standby temperature is 52 degrees, it seemsthat the original fan temperature control is still some difference, because theindoor temperature is 31 degrees, even a difference of 21 degrees.

    These test shotscan be seen after less than 20 minutes of the test, the graphics coretemperature has reached 88 degrees Celsius, the indoor temperature is 31degrees Celsius, in this hot summer, reaching nearly 90 degree heat, the fanspeed to achieve 3603RPM, imagine how much the fan noise.
