●Used for the graphics card and memory card heat dissipation of the AMD-ATi 4850、4870、4890
The power supply module of 4890 can equipped SD19 power heatsink  to dissipate better
●Flexible interchangeable fixture suit for more graphics card similar to 4850
●Advance pure aluminium radiator,better performance in heat dissipation,according with the demands of European environmental protection
●Sc-300 water pump,bigger reserves,no maintenance for long time,more secure

Details:

●Water block:VG18

Material:pure copper  

Size:87×87×15mm

Surface treatment：environmental protectoion electroplating

technology :skving technology,super large area for the heat absorption,and take away the most heat from the heat source.

ultra-low water resistance,super intensive parallel waterways,higher efficiency in heat dissipation.

advanced sealing technology,leakproof,more reliable.

die-casting for once,more secure

                      connector:inner diameter 8mm

●Water pump：sc-300

                       flow:max300L

                       raise:max1.9m

                       capacity of water tank:150ml

                       voltage:DC12V

                       power:4W

                       joint of power supply:small 3P

                      working noise:23DB

                      size:L66×W56×H86mm(net size,without water nozzle and gasket for the reduction of shaking)

                       technology:more quiet,the rubber gasket reduce the shaking and noise effectively,higher safety coefficient,the thickness of the pump shell is up to 3.5mm,the joint used the special technology)

●radiator:12L-T

                         material:pure aluminium

                         speciafication:120*120 radiator

 size:120×120×35mm

   connector:G1/4 screw thread

surface treatment:baking varnish for the surface of the side face,the middle the primary colour

technology:the international 8mm heat dissipation zone,enlarge the heat dissipation area more effectively.weld and solder for once,enhance the heat dissipation performance greatl,which is 30% better than the copper radiator.

Certificate:European ROSH environmental protection certificate

●Fan:120mm quiet fan

                        Size:120×120×35mm

                        Rotational speed:1650+10%R.P.M

                        Working hours:100 thousand

●Tube:N8 transparent tube

                       Size:inner diameter 8mm,outer diameter 11mm

●Coolant:SC-L500 special liquid

passed certificate of the insitute of Great Wall.good performance in heat conduction, corrosionproof ,anti-evaporation,good fluidity.
