Might be a stupid question, but it's the small things that people forget sometimes. Did you connect the power cable?
yes i connected the fan to the sys fan on mobo and the water block to the cpu fan connector
Maybe I missed it but I didn't see what mobo you have, so these comments are based upon my experience with mobos "in general".
I would switch your power connections so that the radiator fan is connected to the CPU fan header on the mobo and the pump is connected to the sys fan header.
Here's why - Most mobos have a fan controller built into the BIOS which will control CPU temps by raising or lowering the speed/voltage of the CPU fan header. As the temp of the CPU goes up, the BIOS will increase the speed of the fan connected to the CPU fan header. This makes more sense than controlling CPU temp by regulating the speed of the water pump, which may or may not even work. Meanwhile, with the radiator connected to the Sys fan header, the radiator fan will speed up or slow down based upon mobo chipset temp. So, your CPU could be getting hotter and your cooler and the BIOS will respond by speeding up the water pump, which may not even effect the CPU temp! Does this make sense?
Connect the radiator fan to the CPU fan header and the cooling system pump to the second CPU fan header, if you have one. Otherwise, connect the pump to the Sys fan header.
