3770K OC Temp Issue?

I have been running my 3770K from 2012 - 2016 at 4.3GHz using the AISuite (I never really monitored the temps at the time as all was stable). Recently I uninstalled the suite and manually OC'd to 4.5 by changing the multiplier to x45 and voltage to 1.230v. Its stable but it is getting really hot, Idle temps are between 44-47 on all cores and just watching a 4K video on youtube temps hit 75-85 degrees C, sometimes one of the cores hits 91. I only started to really monitor temps after fan speeds started to spin up to 90% just to keep temps in control.

(while writing this my cpu clockspeed was 1600mhz and VID:0.9407, all cores were at 43-47 degrees)

I recently changed thermal paste from IC diamond which I applied in 2012 to thermal grizzly kryonaut which made little to no difference. I find this odd as I am using H100GTX with a custom fan curve via bios and speedstep is enabled. (Also have a 200mm intake fan with no obstruction, rest of specs in my sig)

The only method I've seen that would provide a noticeable difference is to delid (with Rockit tool) and apply liquid metal.

My questions are:

1. Is there anything I can do in the bios to reduce idle/load temps?
2. Is it worth deliding a CPU from 2012? (I am willing to do this) considering the fact that I have no intentions to upgrade my CPU/Mobo/Ram anytime soon, I would most likely upgrade my GPU one more time before looking to build a new PC as I am running it with a 4K monitor my gaming performance is 99% of the time GPU bound.
 
delid is the only way to get it down, with it delidded, you will probably be able to hit a higher speed with more volts before hitting same temps

You could try a lower voltage with higher LLC to get the idle down
 
Hard to say what the cause is if you weren't monitoring temps before but perhaps you made a mess of applying the TIM. I have the same CPU at the same vcore albeit clocked slightly slower and mine idles at around 30 without speedstep and I rarely see any core go above 70 when gaming. That's on air too.

Same here.

OP re apply thermal paste and resit cooler otherwise maybe cooler run out of liquid or pump is not pumping probably.....
 
how did you apply the thermal grizzly ? when I first tried it I used the pea method and it didn't spread evenly and cover all the heat spreader, whats the water temps and pump speed on the h100 ?
 
I usually use the pea method to apply TIM but this time I used the included spreader ( it was a real pain, took ages to spread evenly) but I had to keep adding a bit of TIM to fully cover. Maybe I did mess up the TIM application; I was thinking of cleaning and using the pea method again.
Not sure about pump speed as I always used aisuite to control fan speeds and so I have never plugged in h100i gtx into usb header or used the corsair utility. I will also try to find the usb cable and check with corsair utility to confirm pump speed.

Is the pump failing in you aio, how old is the cooler

Solution found; it was the pump speed I believe. I found the usb cable and plugged it into the 1394 header on my mobo as I have no other spare usb headers (this worked fine). Loaded up Corsair Link it was already set to performance now the temps are:

Idle: 35-40 degrees
Load: 74 degrees (during cinebench run), Now when playing 4K videos in youtube its between 45-50 degrees.

System is overall much quieter now, thanks for the tips people! Seems without plugging in the AIO using usb the pump speed stays low?
I think I still will delid in the future.
 
You could fry part of your board by using 1394 header with USB connection as pin usage are not same. Buy a internal usb header hub if you dont have any spare or remove one of the usb headers and connect your pump there so less usb ports but working pump.

Noted, I have moved it to the usb header now. Cheers for the heads up, I just realised my monitor has x2 usb 3.0 so that will work fine in their place.
 
Those temps still aren't great for 1.23 as in extended prime runs you'd be around 80 maybe. 1.23 for 4.5 is good though.
 
Another vote for delid. I did my 4770k and the temp decrease was massive! Easily 25 degree improvement.

Just go the whole hog and use liquid metal TIM under the heat spreader its worth it IMO.

Seems even after plugging in the AIO to the usb header my temps started to rise again idle: 47-50 and load 80-95 degrees; it actually got worse.

So got some Conductonaut and the Delid-Die-Mate 2. I delidded my 3770k applied the liquid metal and now system is way quieter -
Idle: 34-38 degrees
Load: 65-71 degrees (10 mins of prime95)

I noticed the pre-applied TIM was a joke; pretty much rock solid and hardly any on the actual silicon. The delid was worth the risk/work and time.
