4770k is known for high temps

It's same as i7 4790k .... too much adhesive inside CPU.

Your only option is to delid CPU.

Run a stress test for 15-20 minutes and touch with your finger the cpu heatsink.

Then report with how hot it feels and if it's possible to hold your finger on it or something, just describe the touch experience.

Hitting 72c in a stress test and you're worried about that? Shit, you don't even want to know what my 7700k hits then.

Where is the radiator air being pulled from?

what they say.

 

delid and apply better TIM

Yes, there are two heatsinks on it due to it being a two fan design, the one which expels the air from the case is warm to touch and i can feel the warm air coming out

Yeah that's bad TIM inside the cpu then, if the cpu is 84°C and the cooler is "warm to the touch" it's barely moving any heat. If there was good TIM it should be hot AF and impossible to touch for a few seconds.

 

As suggested above, delid, change TIM and put the lid back.

It also depends how fast do your temps jump up.

In my case, i7 4790k on stock settings jumps from 35°C idle to 75°C in 5sec after turning on AIDA64. Then after 20min after my water loops get a bit more hot, it comes to 85°C max.

So if your temps jump to 80 in few secounds, that's bad adhesive inside your CPU for sure. TIM itself is not half bad inside the CPU, but there is too much adhesive (black "glue that's holding together IHS and CPU plate).

Deliding would solve your problem, but to be more safe, you would need to buy delidding tool. You can do it with razor, but it's very hard and a lot of people destroy CPUs that way. You can use vice method, but again risk of bending CPU plate. Most safe way is delididing tool from rootki88 or der8gauzer or something like that. But it does cost extra money.

 

I gave up on my 4790k and I just leave it at stock settings. I already ordered delidding tool, but after 1 month I still didn't get it (always out of stock), so I ended up taking my money back and decided simply not to delid it. Less problems and risks in the end. I already feel bad for the guy who will buy this CPU from me in 1-2 years when I decide to upgrade my rig with soldered CPU
