Recommendations for high CPU temps

[Zack Brown]

My current setup since 2016 is:

 

Case: NZXT H440

Motherboard: Asus Z170-A

CPU: i7-6700K @ 4.01GHz (It somehow automatically overclocked itself)

Fans: 5x be quiet! SilentWings 2 140mm

CPU Cooler: Corsair H110i GTX

 

Recently temps have been reaching 100C during gaming and idling around 65C. I haven't had much luck on controlling the fans' RPMs due to some connection issues I believe. They have been running on ~1000RPM since I got them.

When idle, the CPU cooler fans run at 1020RPM and the pump at 2010RPM.

 

So my question is, what do you recommend in terms of fans/coolers to lower the temps?

can you access the BIOS? Can you change the fan curve that way? Or not? In which case try to get the CPU back to stock. It could get damaged if it is like that for a while./

I assume therefore that this wasn't always the case and significantly better?

 

If yes

- Confirm pump seems to be working audibly or feel tubes for apparant water flow

- Tip the case back and forth to see if there is a air lock somewhere in the system

- Unmount the AIO and give a good shake to dislodge air bubbles

 

If no (i.e. there was a chance it was always like this and you didn't notice)

- Remount the AIO with more mounting pressure to make sure there isn't a mounting issue

 

Also I think this model came with a USB cable and connects to CorsairLink/iCue and so that should give you fluid temperatures which are also useful to have for diagnostic purposes.

I've done all of the above. Reapplied thermal paste, cleaned off all the dust from the fans. I can confirm the pump is working and there is no major change in temps. I think this might be a voltage issue.

Voltage of CPU? then yeah sure, that would be the single big difference if you think somehow that changed.

Core voltage was 1.325V, I reduced it to 1.2V however the temps are still high (this was before I applied the thermal paste). I think there's something in the BIOS I need to do but I'm not sure. Any recommendations?

I can't control the fan curves even through BIOS. The overclock is literally only 0.01 more so I don't think it'll affect anything...

Were you OCed before? If you are unsure you can do a CMOS reset and see if resetting the BIOS settings gets you back to before.

I did that, core voltage was set to 1.28V. I lowered it down to 1.2V, that didn't work and other voltage values were changed for some reason. I tried to change it to 1.2V again, it worked but the other values remained the same (higher than usual). I then changed the other values (such as DRAM Voltage, Standby Voltage, etc) to their standard ones as listed in the BIOS. I got a black screen, rebooted and it put me on POST. This time, the core voltage was changed to 1.28V, while all other values remained the same (standard ones that I put). I tried changing it to 1.2V again but I got another black screen. Ideas?
