hey, got my 1.3 to 1.51

seems pretty good, seems to be 51 idle going up to 55 on load

now i know this cpu can take 71 max, but want to keep away from that, thinking of pushin for a few more mhz as still seems to be ticking over nicely, do you think 55 idle (so will be 60, maybe a tad more on load) would be ok? or would that be pushing it a bit high and ill be needing to purchase a new heatsink?
