I am having issues with my Macbook Pro recently being extremely slow, especially when it's hot outside. It became so bad that I couldn't even connect my 5K display and have too many tabs open.

I manually set the fan on the highest setting and checked the temps but they are only around the 60-70 degrees range, yet there's a lot of throttling going on.

Is this normal?

-- i already tried to re-install mac completely but it didn't work

Having almost 500% CPU uptime on kernel task is certainly anything but normal...

I ran the diagnostics (D on startup) but it didn't return anything unusual :(

I have an appointment with Apple this Thursday but it's quite a drive and I'm afraid they'll just say: it's me..

Last night it was a little cooler and I was able to work with the laptop. But I still saw the kernel task pop up often and had very poor performance. Temps never go over 75 degrees but I still get the kernel task.

Thanks guys, I think it's caused by overheating also. But at 70 degrees I do wonder if it's a faulty sensor or something else. Anyone ever notice this behavior at similar temps?

I read these CPUs can easily hit the 90s..

Not trying to sound coy, but does it matter if its a faulty sensor or something else physically wrong with the laptop? Either way its best to bring to apple for repair.
