If your software is telling you that you're hitting 100C, then you've obviously got a cooling issue.

The Core i5 processor will throttle it's speed if it gets over what Intel refers to as the 'TJ Max' which is somewhere around 90C. Notice that VLC is set to use hardware acceleration and QuickTime runs accelerated by default as far as I know, so the problem is probably not related to this. Are there other causes and solutions I should fix? (Save hardware problems and repairs).Is a full and reinstall likely to fix the problem?.Is the problem simply due to the CPU being a i5? Are i5's ridiculously much slower than i7's?.Is the Mini actually designed for and supposed to get so warm (100 degrees celsius)?.The guy who sold me the thing said he already reinstalled it, but he may not have done a full format first.īefore I go through the trouble of formatting and reinstalling, does anyone have experiences and tips to share of similar situations? Encoding PAL videos to mp4 with ffmpeg goes extremely slow (around 1 second of footage per second, while for comparison my MacBook Air 2014 manages 5 seconds per second)Īpple said '80% of the times doing a full format and reinstall solves problems like this'.The process VTDecoderXPCService sometimes takes several hundred percent while playing video.Indicated CPU usage in Activity Monitor seems to increase proportionately with CPU temperature (and how long the machine has been on), but this is somewhat unsure.The iMac (and previous Minis) never got anywhere near as hot. The machine gets extremely hot, at most CPU temperature 101 degrees according to my temperature utility.Playing mp4 movies in both QuickTime, VLC and in webpages in Safari works fine for some time, but after a while starts lagging.I used to have a iMac 2006 earlier, and to my surprise the Mini 2011 seems to be much, much slower. I just bought a Mac Mini (mid 2011) secondhand with the following specifications:
