I was wanting to reapply my thermal paste and can't seem to figure out how to take off my Cryorig H5 cooler. I tried slowly unscrewing the 2 screws that were used to secure it, but while it does seem to get looser it doesn't seem to ever fully unscrew. Just not looking to break anything by forcing it. For some reason the product manual doesn't have any information on how to uninstall it, so any help would be much appreciated!
