So I have been having issues with my CPU temps and I was getting fed up with them, so I created a thread asking if people would de-lid my 4790k since the temperatures were just stupid.
I then decided to talk to my dad and see what he thought, and in the end I took the cpu out and popped it in a vice, popped the IHS off and applied some Artic MX4 and reseated the CPU, then applied some MX4 to the IHS and fitted the H100i's Block and booted the pc.
PC booted fine and temps were abit lower, not a staggering amount but 2c per core and the core temps are much closer together.
Prior to de-lidding the CPU I had tried multiple different CPU voltages and the pc would crash with anything lower than 1.3v or the CPU VCore set to Auto, when running OCCT with or without AVX enabled.
After de-lidding the CPU I am now trying different voltages again and have found that, I can now run OCCT with AVX enabled at 1.25v and also 1.18v set in the bios and it runs for over an hour.
I am still testing with different voltages (1.16v) to see how low I can get the voltages with OCCT running with AVX for at least 1 hour before, I then go to trying to run for longer.
So since de-lidding the CPU I am now able to run lower voltages which I couldn't prior to de-lidding which I personally find strange although it could just be a strange coincidence.
Also I have notced that voltages also do not seem to be affecting the temperatures that much.
Ambient room temp 24c with a core voltage of 1.25v the peak temperatures were 80c, with 1.180v the peak temps 76c and now with 1.16v in 4 minutes of testing the peak is currently 73c.
I have some Coollaborty Liquid Pro coming on Tuesday which I am going to put on the Die and then test again.
Cooling is currently a Corsair H100i with 4 Akasa Apache Black's in Push/Pull.
Now the temps still seem high to me, but do you think it's coincidence that the voltages are now being able to run lower and does anyone have any ideas about why the temps are barely dropping?
