the hsf is damn big.. but after installation without thermal paste. i notice there is no slight difference between my stock heat sink without thermal paste too.. hmm.. should be the environment's temp.. later i'll change the location.

yeah.. the top fins arent hot at all.. hell the mid hole is for you to plaec your finger into to feel it.. remember to test it using your finger, not your didi.

i think the full potential of ninja can be achieved if you cool the fins near the block. look closely and you will notice it.but most mobo design like mine makes it hard to mount the fan properly
