Aurora R14, swapping fans and errors

I bought 3 be quiet fans and swapped out my stock fans from alienware to use on my old pc.

Sometimes if I boot up my pc, fan #2 would fail and if i restart right there, it will be working fine.

I've returned and gotten another fan but the same happens.

Then I tried to swap the fan around. Every time it would be fan #2.

If I put stock fan back, everything would be fine.

Any geniuses here can figure out why this happens?
