My 2015 MBP is thermal throttling like crazy when it is used for an extended period of time.

What’s odd is how inconsistent the throttle is. Sometimes it will sit at 95+ degrees Celsius and not throttle. Other times it will throttle at 85 degrees Celsius.

Once it throttles, it maintains the throttle even as temps drop and stay low. Sometimes temps drop into the 50’s and it still maintains the throttle for another 5 minutes.

When it throttles, it limits the CPU clock to 800Mhz. Which makes my computer a lag fest. Makes it unusable.

So my questions are this:

1. Has anyone else had this problem?
2. Is there any way to bypass/disable the thermal throttle? Yes I know it could cause issues, no I don’t really care because this computer is on it’s last legs anyway with a partially dead LCD screen that will cost almost as much to fix as the computer is worth. And there’s still the safeguard of a shutoff if temps reach critical levels.
2. Will cleaning my MBP’s vents help at all?
3. Are there any external cooling setups that will help? Funny story, i held my laptop in front of a desk fan on high and it actually made it hotter. Probably because it’s blowing back hot air.
