Sorry about the confusing title.

Mid 2012 Macbook Pro Retina 15", 8 gig ram, i7 2.3 GHz

In OS the fans run full speed all the time and programs, etc. run slow. The same machine, using Boot Camp, has Windows installed. In Windows the fans run full speed, but programs, etc. run normally.

Could this be kernal panic caused by the crappy tantalum caps in the buffer circuit?

Thanks

Sensor issue.... You need to run asd to find which sensor is misreporting, But if it doesn't have liquid damage I'll be willing to bet that it's trackpad.

High fan speed, slow OS... Test with new T-Pad and cable. Just plug new in, no need to fit it just for testing.

Thermal Interface - Processor ... TIM Test 75 percent GB (test #4)
ERROR -- 255

AirPort (test #41) - Wake on Wireless...
ERROR -- 20 [WakeOnWireless test failed, invalid wake event]

Everything else passed.

No T-pad and cable on hand... ordering one.

When the EFI fan test was going, the fans adjusted speeds. When the test was done, the fans went to full speed again. Ran the test once and then a tree cycle loop, no errors.

well if its not giving any errors there probably is a good chance there is non. did you check to see how hot the cpu and gpu are getting? maybe its getting hot and "needs" the fan at full. the other thing to consider testing is a different hard drive with osx to confirm the osx and drive are good. also in your first post you thought it might have been a kernel panic, Did you actually experience a kernel panic?

Did you do a PRAM reset? In ASD you can click the hardware profile and see all readings of the sensors. Are there any temp sensors that are reading high?

to dukefawks - reset PRAM. No joy. Will look in ASD.
to nate8organic - Just working real slow and fans running full speed.

The case is cool in OS and Windows.
