Default heat sink

Would a heat sink rated at 1.3 C/W 11mmx61mmx35mm be enough on each side for a 600ma hot rod?

Thanks

W/C is the key. 1.3W/C when receiving 12W heat per rail assuming 10V across each Mosfet @ 0.6A they gonna rise 15.6C above box's ambient.

If your box is roomy, ventilated, even with 40C inside you are safe at under 60C on the fins.
