There are cheaper options too for example:

There's only one M2 slot on the motherboard so you need it to install a second m2 pcie nvme drive (i.e. use two drives).  Otherwise if you aren't using two M2 drives it basically has no benefit.

Basically all it does is add another M2 NVME slot to your pc.

Oh yea il return it i thought it will help with overheat
