Hi Guys

I am facing a wiried issue with the fan speed or pump speed or fan opt fan speed.

I have a h100i v2 connected the top exaust stock 120 high sp fans.

the cpu header is connected to cpu fan header and opt fan i connected red led sp fans .

the cpu is showing 1500rpm max but the sp fans were showing 3200 rpm

Not sure how it is feasible as the rated the sp fans are 1600 rpm. I have only connected only one fans.

The CPU_OPT header is slaved to the CPU-FAN header. Hard to make out exactly what you mean because your post is ambiguous. In any case, you shouldn't use dissimilar fans on those two headers. Move the SP fans to a chassis fan header.
