MBP high idle 50C and working temp >80C?

Hello,

I recently reformatted my Early 2011 13" MacBook Pro with Sierra and while everything runs fine, the idle temps seem abnormally high. It idles around 50-60C and goes upward of 80-90C with more tasks.

At 80-90C the fan blasts away and if I am on the battery, the battery jumps to 2% no matter what %age I was at.

Any ideas of what may be wrong? Is my thermal paste not working properly?

Here are pics of my idle and working temps

Any help would be greatly appreciated!

Have you replaced the HDD cable or thermal paste? How are your temps now?

If you haven’t already down load this app: TG Pro it’s by far the best fan & temp monitoring app. Let’s let it run awhile so we can get a good two to four days of running to see what’s happening. You’ll need to full version to get the loging function. Paste the log file here for us to see.

Many 13” systems had issues with the HD SATA cable. Other than doing a good dust out I would recommend replacing the cable. Here is the IFIXIT guide you'll need to follow: MacBook Pro 13" Unibody Early 2011 Hard Drive Cable Replacement? I would strongly recommend you use the newer version of the cable which you can find here: MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable- Apple P/N 923-0104. This 13” MacBook Pro 2012 cable is the better one. That might fix your issue.

How can we connect a 2012 cable to a 2011 macbook pro? Are they compatible at all? Why cannot he go with a new 2011 cable only?

The HD SATA cable is what we are talking about here and the cable design was improved in the 2012 model which is why we go with it. It is the exact same pinout on both the logic board and the drive (compatible). The older cables create a lot of problems both creating heat and data reliability issues. I've been fixing these systems for years and I always use the better cable in all of the 2011 or 2012 systems.

Think of it this way... You need to sew on a button onto your pants you can use a light weight thread you can snap in your hands with ease or you can use a stronger thread which you can't and need to use a knife or scizzers to cut. Which would you use to hold up your pants? I hope its the stronger!

This is no different! Use the better cable!
