    Installed Second Life just and was on it for 2 minutes and the fans went high as they do on some graphic intense apps, but then it was going louder and louder, so I looked at iStat and it said the CPU was running at 94C, I instantly closed Second Life but I'm wondering if my Mac mini needs replacing? anyone else's CPU run this hot?
    I've posted a screenshot of my current normal temps, are these normal? Also the fan is running at 1800 rpm.

    The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat (around 100C/212F - 105C/221F, depending on your processor). iStat Pro will give you accurate readings of your temps, among other things.

    Unless there is a rare defect in your Mac, your temps are well within the normal operating range, considering the workload you're putting on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.

    Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). They will spin faster as needed to keep temps at a safe level. If they're spinning up without increased heat, try resetting the SMC. Also, make sure you don't block the vents, which are located at the rear, near the hinge.

    A few things, both of those apple KB articles say "under normal operation the portable computer may get hot, if so remove from your lap and place on a stable surface." hardly reassuring when the OP's temps are near the thermal throttling limit. Secondly, taken directly from the mini's tech specs

    If the OP's ambient air temp is close to that limit, or the ambient air temp inside the mini's chassis nears the limit, I would be worried.

    OP please see the link I posted, it showcases my i7 mini's temps, and others who are running in the 49-60*c range idle. My mini never gets past 75*c now under 100% CPU load.

    Thanks for the help Kyle, is your mini the dual or quad i7?

    Mine is the dual core i7 the non server w/ the 6630m chip), 8gb RAM and a 7200rpm HD, the 7200rpm drives are known to give off a bit more heat, aswell as the video card when pushed. You can check out smcfancontrol or the one I use fancontrol and adjust the fan speed, I have mine at 2500rpms, but find a value that works for you.

    I would also advise getting more airflow underneath by raising the machine up alittle bit as described in my link.

    Try those things and your mini temps should go down!

    I have the exact same spec as you, I've raised the mini on a roll of Sellotape :p
    Do you have Second Life, it only seems like it's that app where the temps go crazy.... even tho the CPU load is only a bit
