There is not much difference between a four heat pipe and a six heat pipe radiator, just a different number of heat pipes. The four heatpipes are more economical, while the six heatpipes have better cooling performance.
Look at the TDP design and choose based on your cpu power consumption. Generally new process cpu (1228nm), TDP under 80W, 2-3 heatpipes; 95W to 120W, choose 4 heatpipes. 130W or above, use 8mm 4 heatpipes or 6mm 6 heatpipes/double tower combination.
The difference between a branded 4 heat pipe air cooler and a miscellaneous 6 heat pipe is the number of heat pipes and the quality of the brand.
Currently dozens of dollars of heat pipe radiator heat pipe diameter is usually 6 mm, more than a hundred dollars began to appear 8 mm heat pipe specifications of the product, the price of the product is generally higher 8 mm heat pipe, there are products are 6 mm and 8 mm mix and match. 8 mm heat conduction is stronger than the 6 mm heat pipe.
If you don't overclock, it's just a normal i57500 power consumption CPU, with the Xuanbing 400 four heatpipe cooler, and the Big Frost Tower six heatpipe cooler comparison, the Big Frost Tower temperature is just a few degrees lower than the Xuanbing 400, all no more than 55 degrees.
