先上图,上面是670 ftw的老款,下面的是新款,货号都一样
PCB基本没改,供电改了,电容少了,电源控制器也改了。
As far as the chip differences on the back of the PCB
Old Chip: RT8802A -- 2/3/4/5-Phase PWM Controller for High-Density Power Supply - Richtek Technology Corporation
New Chip: NCP5392Q -- 2/3/4-Phase Controller for CPU Applications - ON Semiconductor
Not entirely sure why the change/removal of the caps and whatnot

老外换水的时候发现的,求大神指点对稳定和啸叫有无影响,超频啥的就不考虑了,估计会更弱 |
