    Recently when I play Call of Duty 2 (FPS Game), my computer will just randomly turn off. There is no sign of an error or any warning of this. I thought it might be because my CPU is overheating, though i have never had any problems before.

    I downloaded Motherboard Monitor (MBM) and was a little frightened to find out my CPU idles around 60C and reaches as high as 87C while gaming. The airflow in the case is ideal, having the PSU exhaust right above the heatsync, and a secondary exhaust on the back of my case, as well as (2) intake fans on the bottom front of my case.

    So I took off the heatsync, cleaned the processor and the die, re-applied some thermal compound and rebooted. Still 60C. Still up to 90C while gaming.

    Can anyone help?

    The intel prescotts do run pretty damn hot, but shouldn't be that hot!!

    What sort of case temperatures are you at?

    Also does the heatsink feel warm/hot to touch? It should do if the cpu is at those temps and there is a decent contact between it and the heatsink.

    Current case temp: 38C

    As far as the heatsink being warm/hot, it feels about room temperature. Guess I found my problem, but what is the solution? As far as I know the heatsink is installed properly.

    try rotating it 180 degrees, also what thermal paste are you using?

    Maybe grab a screenshot if poss so we can see if its anything obvious

    The onboard temp sensor may just be misreporting it. Is the heatsink cool to touch, warm, or hot? At 87C it should be uncomfortable to keep your finger on it for more than around 15 seconds. If it feels cool, I'd doubt that reading is accurate

    Ok well i just detattched the heatsink again to make sure everything was correct, now it's idling @ 55c. This is still a bit high correct? If so I will try rotating it 180deg. to see if that makes a difference.

    Edit: Silicone Base - Heatsink Compound (Radioshack brand :wallbash: )

    55°C isn't awful, although it could be a lot better. If you reseat the heatsink with some better thermal paste and ensure that good contact is being made, then you'll be able to get it even lower.

    It could just be that your heatsink you're using is faulty or bad?

    I think however it's your motherboard monitor now showing the temperature properly so your best bet is to get a thermometer or some sort to measure the temperature properly or get a good proper heatsink.

    Uneven surface, poor bonding between the copper core and aluminum fins, bad fan; all those things can go wrong. Its not "just" a lump of metal :p

    There are much better (and quieter) heatsink/fans out there that would do the job just fine. See if you just cant get a hold of one.
