WaterBoy Copper Radiator

I switch on my computer with a very low cpu temp of 25 degree celcus.
Softsis burn was run 30 times to maximum the CPU Utilizaton to the top for about 30 minit, we found
the temperature is around 38 degree (did not turn on the radiator fan) , after turn on the
radiator fan, we run another 30 round of Softsis burn for 30 times and found the temperature drop to 33
degree. This is really amazing. We believe the temperature can even drop to 30 degree if using a Copper Water Block !
Well done Waterboy Copper Radiator.

Test 2 Radiator Heat transfer Efficiency Test
I boiled up a hot water to 80 degree celsus and pour it to the
container, we switched on the water pump and radiator Fan. We can feel the heat is out from the radiator
quicky by putting my hand near the radiator fan. Amazing work, only 30 second the water drop to 40
degree celcis. This is really a good Radiator we have ever seen.

80 C - > 40 C need 30 second only !
