I've had issues with my 2017 MBP running really hot, but never connected that with kernel_task running at 150% CPU until now.
I found a tool called Mac Fan Control, which lets you change the thresholds at which the fans kick in. I've been using it for a good while now. Laptop runs louder, but cooler.
Today my machine slogged to a crawl, became basically unusable to the point of restart -- I don't remember which port the power was plugged into, but this definitely shed some light on the issue. Fan Control wasn't running, incidentally.
