Hi friends. I have an strange problem with my p18e aw. I had buy turbo fan from china guys cicichen for CPU but I notice than when I set fan speed on maximum , the fan speed reduce in CPU load. I have 4930xm and undervolt it on 1.12 with core(41,40,39,39). I think its something about VCCIN. Is there any one has the same problem?? Or know the best value for vccin. If I adjust vccin on 1.8 the screen go out.!but with 1.7 have the same problem as default.any idea??
