P4 2.8E overheating problem

hey i have a p4 2.8e 1m cache with a ic7-g motherboard and for some reason when i check the temp of my cpu it is like 58c at idle. i called intel and they said that its normal for the cpu to be runing that hot. The thing is that i have a thermaltake spark 7+ copper heatsink and fan that blows like a jet and i have to keep it on full speed all the time to keep the temp at 58c. if anyone has had this problem or kno anything about this please reply.
Thanks
