AMD 64 X2 6400+ heat issue

  1. This thing gets HOT! I downloaded PCWizard and it states-
    Core 1=55c
    Core 2=52c
    CPU = 127c

    The issue started when the system would shut down during game play. The Biostar board has a thermal protection setting at 70c and shuts the pc down when I guess the cores reach that mark.
    When I play with the case panel off- No Problem.
    Put it on and it shuts down in 5 minutes of play.
    the CPU HS and fan is your basic aluminum finned/ fan that you would see on any run of the mill CPU. Apparently the 6400+ is a heat beast!

    I got this from Newegg on the way-

    I also plan on some case modification. Venting the top of the case. Adding a side intake. There are no spots for fans on the box. A larger, fan-friendly case in in the works.
    Think the modifications and fixes are on target.
    Any Suggestions?

    The 6400+ is definitely a heat beast, but that 127C figure is wrong. Sounds as if your case is too small. Do you have plenty of room around the cpu cooler? Double-check the heat-sink alignment and thermal paste... remembering that too much thermal paste is as bad as too little. Thick thermal paste can act as an insulator.
    Do you have a way to monitor your fan rpms?

    The case is smallish. Planety of room around the cpu though. I had the AMD cool & quiet mode enabled but I read in a forum that it should be disbled. Now the CPU fan runs full tilt all the time. removed and reapplied the thermal paste. This time I used a silver based non-silicone formula. I just talked to the guy who owns it and he has been playing all morning with the case panels off and it has been fine for him.
    I will make the case mods as listed and I think I will be ok.
