CPU Throttled and fan constantly running

Hi,

I inherited this from my stepson in a pretty tatty condition.

Many keys on keyboard not working, Hard disc on its last legs and worse of all the battery was severely distorted and had bent the rear case.

So, I replaced the keyboard, battery and rear case, (all genuine Apple parts) and fitted new SSD and did clean install of MacOS High Sierra (10.13.6).

The system works perfectly with the rear case off but within 30 seconds of fitting the rear case the fan runs up to full and the CPU is throttled back.

This is doing my head in! Any tips gratefully received….

Tim

How did you get the High Sierra system on this model? It should not have taken it. I suspect this system was put on the drive from another machine. It may also have formatted the drive GUID/APFS instead of GUID/HFS+ (journaled). I would reformat the drive GUID/HFS+ and install El Capitan 10.1 and see if it works.

Also make sure your drive is backward compatible to SATA II (3 Gb/s).

UPDATE 9/23/18

It’s important to exactly which machine we are talking about. You have a:

Apple MacBook Pro "Core 2 Duo" 2.66 13" Mid-2010 Specs

Identifiers: Mid-2010 13" - MC375LL/A - MacBookPro7,1 - A1278 -  2351*

I’ll change the devise icon

This machine will take High Sierra OK, but I don’t know about this program you used to do it. How did it format the internal drive?

@mayer Probably got high sierra on there using dosdude1’s High Sierra patcher. It works for that model MacBook. I won’t be surprised if so.

@mayer I used that patch tool to get HS on my Dad’s old 2009 MBP, just saying!

@ajcooke01 obviously you used your mouth before you looked at what I asked you to!

@mayer I mixed up different computers, lol! I have too many MacBook Pros that look alike and I just can’t keep track of what OS each has and what model each are. I did not get High Sierra on that MBP, rather I use that computer for the rare occasions I need Windows. Sorry!
