PSU blown or Temp Shut down?

    Guys, quick one.
    I don't have a spare PSU so can't just swap it out and check. System is barely turning on and then starting very very slowly then completely cutting out (it will cut out after a minute or two in BIOS too)

    Went into F2 to check on the H/W monitor and the temps look high though. The i5 is running at 90C (can not remember the last time but don't remember it being that high). The system is NOT overclocked

    The heatsink is the standard supplied and the Case has three fans all running at full speed

    :eek:

    Cpu temps should be nowhere near that. At 90C your probably talking thermal shutdown to prevent cpu damage. Cpu fan is definitely running?

    is the heat sink seated properly with thermal paste?
    could it have been dislodged?

    It was probably dislodged. I've had one pin on the stock CPU cooler not tightened before, idle temps on a 3570K were 80°C.

    Yeah that was issue.
    Seemed to be a bit of give, took it off completely and reapplied some paste. Secured it correctly and temps back down to 45-50C

    Nope, but it's not idle either (though it's closer to idle than load. I think it acts as if Speedstep is disabled, so it'll sit idle, but at 3.0GHz, or whatever your chip's speed is.

    Did you clean off the old thermal paste properly before reapplying? 45-50c in bios is still very high...

    Why does the BIOS fan control for main case fan set CPU at 50 by default (first option if I go to manually set a temp on the fan instead of Maximum rpm)?
