question about oc'ed e8500 temps

Temp spread from idle to full load [prime95 load] is:

idle - 32
load - 54

here are the coretemp/cpu-z reads:

[the 49 degrees reading is from like 15 secs into load, it gets up to 53 - 54 degrees after a couple minutes and stays there]


i use the thermaltake big typhoon heatsink



are these temps too high? is the temp spread of 22 degrees difference too wide / is there anything i can do about it?

Those temps look good.
