well firstly, 62C is getting close to the upper limit anyone would want to run an athlon. any higher you would probably get lockups.
there are a number of possible reasons why its so hot.
1. crap cooler
2. cooler has thermal pad
3. poor case cooling
all of these are easily (and cheaply) fixable.
cheap coolers usually have a poor design, fewer fins for less surface area and/or a cheap slow quiet fan. there are oodles of diff designs out there. toms does a decent cooler review. spend some time looking at it.
the cooler can be improved by attaching a more powerful fan... to an extent.
probably better to check No.2 in my list, thermal pad. just about everyone thinks that thermal pads are crap for heat transference, and the better HSF's dont have them at all. get the pad romoved and some thermal grease applied instead.
finally, a cooler is only as good as the temp of the incomming air. if you arnt getting good case ventilation your cooler is circulating the same hot air. not good.
a couple of cheap casefans can do the job.
on front sucking, one back blowing. also have a look at where your cables are, the wide ide rippons can disrupt airflow bad.
remember... how far u go is up to you.
adequate cooling can be done very cheaply. if you want a case that acts like a supersonic windtunnel then its probably gonna cost you LOL
