Fan at full speed and poor performance after repair and waterspill
I have an Macbook Air 13" Model A1369 EMC 2469
and have had a juice spill on the the keyboard. The laptop has worked fine for a long time but after a while the keyboard stopped working on some of the buttons and I replaced the keyboard. I noticed there where some residue on the logic board while repairing and have tried to clean it with Alcohol.
After I finished the repair the laptop turns on just fine and boots like normal, but the fan starts from a low RPM at boot up and then faster and faster until I believe it reaches maximum RPM and is consistently running at full speed all the time.
The laptop has also become very slow and have poor performance.
I have looked into the CPU monitor and the kernel task of the CPU is at 310% with 61 threads running.
What I have tried so far:
- I have done SMC reset, and RAM reset but it didn't help.
- I also did a AHT and there was no error showing up.
- Tried disconnection all unnecessary hardware to the logic board, like airport, camera and speakers, no luck.
- Checked the SSD harddrive via diskutility, it checked out fine. But when I look at the read speed it only reads between 30kb/sec and some times up to 2,4mb/sec. Isn't this very slow?
The spill residue was primarily near the CPU and the SSD drive and that was where i cleaned it with alcohol.
Is this a good question?
