You’ll need to take the MXM GPU board off clean the old thermal paste and pads refresh the paste and replacing the VRAM thermal pads

I would also recommend installing TG Pro so you can get a better handle on what your sensors and fans are doing.

Thanks @danj

Sounds like a fun packed job!! If the machine was a typical PC I wouldn’t hesitate, but I’m not sure I have the courage to open my iMac!!

I’ll order parts and let you know.

Thanks for the advice, much appreciated.
