My macbook is at around 60 - 62 degrees Celsius at light use like web browsing and watching videos and the fan runs at the default 2000 rpm. Both the upper and lower body get uncomfortably warm to an extent that I can’t touch it. Do I need to replace the fans or the heatsink? Update (05/24/2017) These are the stats for 20% CPU usage but the laptop is uncomfortably warm…..correction hot at the top and I can hardly touch the bottom! It’s super hot around the processor and the heatsink at the bottom and the whole top is quite warm. The stats: fan: 4945 rpmambient: 52 degreesbattery max: 43 degreesCPU core 1: 74 degreesCPU core 2: 71 degreesCPU PECI: 74.1 degreesCPU proximity: 63.5 degreesGPU PECI: 69 degreesheatsink proximity: 53.6 degreesmemory proximity: 53.1 degreesmemory slot: 57.1 degreespalm rest: 41.1 degreespct die: 73 degreeshdd: 46 degrees Apps open in the background/everything minimized/ max cpu usage 20%: Safari (had no web pages open)mailcontactsnotescalendarremindersmapsmessagesfacetimeiTunesiBooksapp store And when i closed all the apps without shutting down the CPU temp remained the same but the fan came down to 2000 RPM
@cam2363 Thanks for calling me in. My first thought on this is the heat sink. This one is liquid filled and can develop a leak and cause overheating. When it leaks it usually leave an oily looking residue on the logic board. If you see this then replace it.

yousuf-bilal1 - If you look at your numbers you’ll see the CPU & GPU temps are very close to the CPU PECI & GPU PECI temps, yet the heatsink proximity is about 20 degrees cooler. I can’t say for sure the heat sink is bad just looking at these numbers but its clear the transmission of the heat is not as effective as it should be. I would start off making sure the fans and fin area are clean of dust build up and if you are up to it you might as well swap out the heatsink. Do make sure to clean off the old thermal paste and use a good paste to replace it. I personally like ArcticSilver. If you have TG Pro running here take a snapshot of the main screen showing not only the current temps but the high-water markings. I find that a bit more useful than the straight numbers. As a reference here’s my 2011 MacBook Pro’s view:
I have a few Safari windows open, Pages & Mail running at the time I took this.
Hi, I would suggest use an app to control your fans, so that they spin a bit more faster which in turn will keep the temps down. I would suggest try using this app and see how it works. You could also try and re-apply your cpu compound which will help as well to reduce the temps. https://www.crystalidea.com/macs-fan-con… Hope this will solve your issue.
Going off of what John said, I suggest smcFanControl. Its what I use and it works great. https://www.macupdate.com/app/mac/23049/…
