Thermalrake Pacific Full Kit

[nicklog]

Hello guys
I've bought Thermaltake's Pacific M360 D5 Hard tube cooling kit that includes everything, for my new setup.
After i fixed everything checked the loop and everything when I powered up the PC for first time I got an error for CPU FAN about the fan speed .
The water block didn't light up as well (it's rgb)
I checked on bios and cpu temp varies from 40 to 50.
I ignored that message from bios and installed windows etc just to check if its gonna get fixed or at least if the header lights up but still nothing .
Any ideas what Is wrong with that???
The 3pin cable of the water block is connected to my CPU FAN connector. Should it be in Thermaltakes controller instead maybe, with the radiator's fans and this controller connected to CPU FAN?? That was an idea I got just now basically, by writing this message.
Any help will be valuable. sos
Thank you

UPDATE:
I think I fixed the CPU FAN speed error I had to connect the 3x radiator fans-->TT controller and then the controller to cpu fan connector.

2nd fix was that I just gave power to the block but I think it was only for the rgb lighting nothing more than that.

Now the only problem that exists is that even on idle temps are jumping up and down every few seconds from 28 to 38 -39 degrees C.
I ran a really light benchmark software and it instantly went to 53+. When the benchmark was completed it instantly went down to the same values (29-39)

I spent so much time and effort to the whole built I'm losing all hope.
Any advice or questions for more info are welcome.
