One part from Bykski block make PCB bent so I must cut it, new revision of this block dont have this problem. This show how I can remove Front Radiator I changed fans on top radiator. Arctic P12 have same performance as PW2 but are much more quaiet so now I have same noise but highe rrpm and performance. P12 can run on 850 rpm and give much more static presure than pw2 on 650 rpm with same noise. I bought bykski's GPU holder but I must cut some parts if I want to fit it.
