Heat sink and fan - do I need an upgrade?

Hi there,
I'm upgrading from AMD Athlon 64 3800+ 939 to a AMD Athlon 64 x2 4800+ 939.
Since the CPU is a used one and comes neither with the heat sink nor the fan I'm planning on using my original one.
Is that possible or I need to look for new heat sink and fan for the 4800?
Thanks in advance for your help.

  1. You can try it if not overclocking and monitor your temps. I have used coretemp, and the temp shouldn't go above 60c under load. Or you can check Newegg's stock of open box heatsinks.
  2. I think the stock cooler is the same.
  3. they may not be enough, I know some X2s had big copper base heatpiped coolers while the 3800 is like my 3200 with the puny Al non heat piped small cooler of shittyness....
  4. Thanks for your comments.
    It looks like we have a split decision (50/50).
    I spent some time looking for the heat/fan specs but haven't found them.
    Even though the 4800 uses more power, its temperture ratio is narrower and fits into the 3800.
    Logic tells me that it should support it, but on the other hand the 4800 have 2 cores in one and should tend to heat more. Right?
    Size wise they should be the same, too.
    Any thoughts?
