    I have a 2012 Mac mini i7 2.3Ghz with fusion drive.

    Chrome open with 6 tabs open, and nothing else running (well things like memory clean, cinch, caffeine, Xtra finder, iStat pro, temperature monitor are all on, though Caffeine isn't active) and my mini is at 44-46ºC and and fan between 1790-1805 rpm.

    When I run a game like Minecraft or CSR racing it gets to 60-75ºC with speeds around 3600rpm(I think) .. and it is VERY hot when you touch it. And Lego Batman is terrible!

    Is this normal?
    Should running these types of things make it this hot?
    Should I worry about running these things in fear of permanent damage?
    Should I avoid these games?
    I haven't really played them, because of how hot it got I have just not bothered with them ...

    Bought my Mac in February.

    If you're not already doing so, use iStat Pro (free) or iStat Menus ($16) to get accurate readings of your temps, fan speeds, etc., rather than relying on your sense of touch or sound. A forum member has posted a copy of iStat Pro that has been "tweaked" to enhance compatibility with Mountain Lion. You can download it here.
    The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat. CPU Tjmax = 105C (221F), GPU Tjmax = 100C (212F) on i3, i5, i7 processors. (Source: Intel)
    Unless there is a rare defect in a Mac, most temps are well within the normal operating range, considering the workload being put 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.
    It is also quite normal for your Mac to become extremely hot to the touch during intensive operations. The aluminum body transfers heat more effectively than other materials used in computer casings, so you will feel the heat more. This doesn't indicate that it's overheating and will not harm the computer to be hot to the touch.
    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), or 1200 for the newest MBAs. Older iMacs have 3 fans with minimum speeds in the 800-1200 range, while the newest iMacs have a single fan, spinning at a minimum of about 1400 rpm. They will spin faster as needed to keep temps at a safe level. If your fans are spinning up without increased heat, try resetting the SMC. (PRAM/NVRAM has nothing to do with these issues, so resetting it will not help.)
    The intake and exhaust vents are in the back of the computer near the hinge on all Mac notebooks (except the new MBP with retina display, which has intake vents along the sides at the bottom). The iMac vent is a slot on the back near the top of the computer. Make sure the vents remain unblocked to allow your computer to perform at its best. For Flash-related issues:

    I have a 2011 mini i7, that when using handbrake the fans will crank up to around 5,000 rpm and hold there until conversion is done. This fan speed keeps the heat just below 100C. I have run handbrake for over 24 hours on multiple occasions and never had the unit shutdown.
