hi, unfortunately there is no installation guide in YouTube about V2 (black transparent Fan) and everything is about 200t with blue fan. i have never installed 3rd party cooler so i tried to be careful. my motherboard is asus prime b660ma and a i3 inside..... i installed the plastic Ring on MoBo and its completely fixed , then i had those Black pin fixed so it wont come off...
now here is my problem.
there are Two pin on heatsink that supposed to go over 2 clip in the plastic Ring.
one of those metal clip on heatsink is straight, other one is L- shape.
i guess i suppose to fix Straight one first (i am going to refer to it as S-one from now on), then Fix the L shape one. but thats really Far away and its impossible to do so..... i tried to push heatsink toward straight clip (after that S-one fixed) still, far away! i dont know how much pressure is OK, but now all i think of is that this plastic ring does not match!!!!
any help is appreciated. thanks
