the CPU fan header could be faulty plug any fan into it if its still slow i think the header is knackered :-(
Joe
I apologise after two days of tinkering and rebuilding the whole pc I identified the factors of the problem
1- the fan had a manufacturing error where one of the wires designated to it was torn a bit I contacted the seller and replaced with a new one
2- after taking a look at the cpu I realised the person who assembled the pc for me put way too much thermal paste causing the cpu to over heat beyond the normal degrees (reaching 100c while rendering 1440p videos)
3- the airflow inside the case was terrible due to an outdated psu that's over 6 years old and collected tons of dust tried cleaning it up but the fan inside was running terribly and it made a noise as if a screw fell into it so I replaced it with an evga
4- you were right Mr my fans wires were mixed up and once I rearranged them i saw an increase in the case fans not much in the cpu fan tho
I'll keep updating you once I finish installing the new cooler on how it went
thanks all for the help this is one of the best communities on the Internet
