what was the old cooler you had on the 1090t? and why didnt it work?
you said you used a 1090t, which is a am3 chip, in that am3+ board, then said u are now using a tricore phenom, which is only in the athlon/phenom2 series, on an am3 board
the am2/3 socket should be the exact same spacing, so the mount should work on either
