Store rekt me boys. I had sanded a bit on top off the IHS to make it flat after the 30c fluctuation (serial on IHS still visible) Now no warranty because of user abuse

I'm receiving it back tomorrow then it's getting decapitated and gonna do direct die cooling. Intel sux.

Can't take more downtime by sending to Intel

I decapitated the 9900k with EG starts delid tool on Amazon. Then used this plastic razor to cut through the "solder"



It went through the solder like butter without much risk to die. Solder was like a alumunium sheet

Then buffed the die with some polish on a rag no need to sand anything. I'm doing direct die watercooling. Also setting up my first custom loop but lacking 2x 90 degree fitting b4 I can fire the system up. Should be up and running tomorrow if I didn't wreck anything.

Having the chip at 5ghz I would say cracked die highly unlikely, seeing that difference amongst cores direct die makes me think bad thermistor. Once that diffusion barrier is broken I wouldn't think it last long with oxidation from the air.

bad DTS Sensor.
Chip probably still works fine. But you may have to raise TJMax to 115C to avoid thermal shutdown. Can you stress test it if you raise TJMax and not have it throttle or crash?
