High temp. Cracked die 9900k?

yeah bruh RMA that chip... thats a really bad OCer

I sent it to store today after Intel support pissed me off with questions about what bios version and windows build im using.

Hi,
New bios for x299 are total crap gets hotter and hotter
One would have to go way back to the end of 2017 to get any decent bios and of course win-10 updates bork those

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.

Try rma with intel.
They will propably replace it even with the sanded ihs.

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.

***. Core #4 still 20-30c higher doing direct die cooling. I swear to god must be this Asus beta bios I installed. BRB!

*** I'm going to lose my mind wasn't the bios either.

I delidded the 9900k. Did direct die cooling. Replaced the Kraken AIO with a EKWB custom loop and it's still wrekking me.

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?
