Radeon HD 4850 came into the market, is a stronge “exhilarant” for all the fans of AMD cards. As AMD give the loyal Radeon fans a generous gift, Radeon HD 4850, compare with same grade and price products, has unprecedented performance of the hardware specifications: the RV770 GPU that up to 800 scalar shaders; 512MB/256bit local memory configurations; its theoretical computing capacity is better than NVIDIA GTX260/GTX280; the first single chip (1TeraGLOPS) of trillion calculations in the world. More importantly, these specifications achieve in a single slot graphics card of middling hardware design.
Cost saving result in single slot radiator’s cooling performance is too low, that is a little regret of this almost perfect graphics card. In the test, the temperature is as high as 80℃ on this condition default fan speed of the public version single slot radiator. Radeon HD 4850 could not work safely under high load.
So far, the public version of the HD4850 has been full of each super mart, but non-public version is still rare. In order to completely solve cooling problem, find a perfect partner of the HD4850, PCPOP organize a competition of the HD4850 cooling system.
Syscooling SPVG-1 water cooling kit used in HD4850:
Test result: 39℃ in the ready state, 53℃ in the complete work state. From the result, we can educe conclusion that the cooling performance of Syscooling SPVG-1 is very excellent. The overall temperature is higher 4℃ than circumambience in the 35℃ constant temperature box. The official price of Syscooling SPVG-1 is 368 RMB. The price is a little high, but SPVG-1 cooling performance is very satisfactory.
The temperature of all cooling products join in this competition, in the ready state,
In the complete work state,
After a series of tests, all of the test results are listed in the illustrations. we can clearly see that DONGYUAN Syscooling (东远芯睿水冷SPVG-1) is the best, it is a good choice for HD4850. SPVG-1 cooling performance and silence effect are very satisfactory for water cooling users.
Finally, Syscooling is on the top for absolute predominance, and obtained “the best performance award” promulgated by PCPOP.
