Short:
Problem: My CPU gets way to hot. This happens even at idle. Cannot figure out why. I have tried a lot of things with no luck. I fear the end.
Long:
I have been running an intel i7-3930k paired with a corsair H100i aio since the year that the 3930k was released. The chip still runs outstanding for its age (until now). For at least half of the chip's life it has ran a modest overclock. It ran at 4.0Ghz stable for over 4 years without any issues. Temps at a max would hit 80C under 100% load. This type of load was rare, as I rarely did any encoding/rendering/etc. Mostly just games and servers.
The CPU started acting up a few days ago when it started to take a few minutes to boot up. It would then prompt windows to log off and shutdown right after startup for no known reason. This is when I found out my CPU temps would reach over 90C just from startup. It will get just as hot in the BIOS. If windows takes too long to boot up the pc will tjmax and cut power instantly. This obviously leaves the pc as useless. The issue is clearly the heat from the CPU, I just cannot narrow down why.
I have been building computers for around 8 years now and have yet to have a CPU go bad on me. I have ran out of idea's to try and fix this problem. It may be the case that the CPU is actually done. I have tried many different methods to get the heat down but had no luck.
**Room temp: 72deg F.
**CPU overheats at idle.
Things I have tried:
- Started by clearing cmos to factory settings to set my cpu and ram to stock speeds.
- Unmounted the H100i and applied a new quality thermal paste (Arctic Silver or something like that).
- Re-seated the CPU.
- Ensured all fans and airflow are working and optimal.
- Ensured the pump on the H100i is actually pumping.
- Changed the liquid in the H100i (The old liquid had mold in the loop when I drained it. I was concerned that the mold might be clogging the loop, but you can feel the flow through the rubber tubes). **You can feel the liquid get hot in the tube when the system is running.
- Cleaned the mold out of the cooling fins inside the head of the H100i. (The backside of the copper contact with the IHS).
- Undervolting the CPU in the bios. - Temps ran the same at 90C until shutdown and was surprised that windows would launch by taking .15v away from stock voltage. (Stock: aorund 1.25v... undervolted to: 1.1v) When this didn't work I reset this back to stock.
- Disconnecting extra BS that is not essential to the machine running.
- Ensured that dust is not an issue (In case/fans/radiator/etc.)
- Ensured that the BIOS is up to date (Not that this should matter as it is running the same version that the pc ran fine on for years).
- I am sure I have tried more, this is all I can think off the top of my head..
-------
* When I let the CPU cool down to room temperature then start running the system. It takes less than 1 minute for the CPU to reach 90C in the bios before I pull the plug.
* Delidding is not an option as I believe the i7-3930k is soldered.
* Everything works the way it should. Windows and Linux will boot and run. All devices work. The temps (and consequently system shutdowns) are the only problem.
* No error codes
* Temps on GPU / HDD / SSD are fine.
Anyone have any ideas? Or is the chip doomed?
I appreciate your time.
