SSD found by Bios but don't boot Windows
Based on your situation ,Try below steps:
This could be due to Loose Power/SATA cable if SSD is not detecting, interchange powercable & SATA cable for your SSD.
Your new cooler might be consuming more power than required, is there anyway you can remove the cooler and try boot up again?
Verify Boot Mode if boot mode alreaddy set to legacy change to UEFI and see, if UEFI was set earlier your computer wont boot with Legacy Mode. (Verify with Possible SATA Modes as well RAID/SATA if you dont remember previous configuration).
