Did you make sure that either the heatsink came supplied with a thermal pad, or that thermal compound was applied to both the heatsink and the CPU die(this is recommended over using the pad)?
Are the computer's vents unobstructed, is the computer located in an open area, are all fans running, and are there any wires/cables in the airflow path of any case fans?
What's your case fan configuration(number, capacities, and locations)?
If the above turn out to be ok, then remove the computer's cover, and run an external fan.
If that does not help, then you may have to install a more efficient heatsink/fan on the CPU.
If you have simply built this lot into a standard case without adding additional case fans then the figure of
58-65C doesn't suprise me, with such a hot CPU extra case fans are a must from the word go.
Obviously the enviroment the PC operates in determines the temperature that can be achieved so if you do live in a warm climate temperatures are always going to be on the high side unless more radical cooling solutions are employed.
Ideally you want to achieve a maximum temperature lower than 60C, this is easily attainable if your PC runs in a moderate climate but for those in warmer climbs much more attention is needed and better/additional cooling products need to be fitted.

Thanx for your prompt responses. I have 2 case fans run ning 1st at front lower end of the case 2nd back of case higher up. The heatsink did come with a pad but judging from whats been said i could install another 2 case fans and clean the heatsink and put some paste on.
Is the heatsink oriented properly? The recessed portion of the bottom of the heatsink should be over, but not on, the raised portion of the CPU socket.
Yes the fans are blowing in the right direction, I had the machine on test for 2 days and it never touched the 60% mark always between 53-58 but its been put into a computer desk now which only gives it about 1 1/2" clearence either side and its also in a warmer room.
if i could get it to run at 52-55 would that be safe.
My system is also in a desk enclosure, and it too ran hot. This desk has a rear horizontal support piece that has height just enough that the air exhausted by the two rear fans is deflected back into the enclosure, which heats the chassis, and is possibly also being recycled by the front intake fan. I added a small external fan blowing into the enclosure that gives enough airflow to push the exhausted air out of the rear of the enclosure. This small addition solved my problem.
Also, if your CPU cooler is one of the top 3 listed at the below link, then another thing to check is that the rheostat
is set to the high fan speed setting.
If the heatsink is properly mounted, the thermal pad is in full contact with the CPU die, and the room temperature is no hotter than 70-75 deg. F, then an efficient cooler should be able to keep the CPU's temperature below 50 deg. C with just Windows running if the case is being properly ventilated.
Sounds like you may need a better cooler.
I think the manufacturer is being over generous with this coolers rating and under more favourable conditions this cooler might be adequate but as it stands at nearly 75watts of heat this baby needs some special treatment and that can't be bought for 6.50+vat.
