I recently did my first delid on my 9950x3d and did the floss and Iron method. Everything went pretty smooth. I added some conformal coating to the smds and polished a bit the die with toothpaste & thermal paste. The last step was to finally mount my 420MM AIO to the Direct Die Frame by Thermal Grizzly & used Thermal Grizzly AM5 Offset Mounting Kit. I used thermal paste between the die and water pump because i didn't have liquid metal at the moment. Upon tightening the thumbscrews its was kinda hard to gauge how much torque to add. Unfortunately i added too much and cracked one of the die therefore killing the cpu.
$700 Dollars down the drain GG.
I bought a 9800X3D since i really only use the PC for Gaming and for Entertainment. Im looking forward to delidding the 9800X3D, Im not sure how much of a benefit it would be aside from the drop in temperatures. Perhaps next time i will just spin the thumbscrews and roll with that. Any tips for people that use AIOs with direct die would be greatly appreciated.
