I have an i5 4690k overclocked to 4.40 GHz and I've had it like this for months now. I use a Hyper 212 EVO with two fans in a NZXT H440 with all case fans filled. At idle my CPU sits at 45-50 degrees (C) and under load its at 78 degrees, Is this normal? I use a good quality thermal paste and covered it well and I'm currently in England where it's 1 degrees outside and about 18 degrees in my room. My R9 280X sits at 42 degrees.
Im just worried that 78 degrees is hotter than what it should be at and it heats up my room a lot after an hour or two and it triggers my GRID V2+ fan controller and all my fans are blasting at max RPMs and its loud.

That sounds a bit high to me, especially with the ambient room temps being 18c. At idle are you leaving the pc rest for a good 5-10min to get the reading and is it truly idle (as in 1-2% use, anything higher and it's not idling but performing background tasks). 78c isn't reaching the state of thermal throttling but more what I'd expect for a torture test while oc'd. Gaming or other normal tasks should be lower, more like 60-65c.

Did you auto overclock? If so the preset voltages the motherboard is using could be causing excessive heat, they tend to be too aggressive in favor of stability rather than efficiency. Manual overclocking is generally better while working out stability using lower vcore. Core voltage = heat.

There's a thumb...

Well I would say 45-50c idle is a bit warm for a 212 evo unless you are using some kind of really relaxed fan proflie for idle. But 78c is fine for that cpu with a slight overclock under load, its okay into the upper 80s. What is cpu voltage set to?

There's a thumb screw in the center of the 212 evo at the base directly in the middle of the "X" retention brackets. If you turn it a little (it's a booger to get your fingers in there) it will increase pressure against the cpu and help provide better contact. I had to do that with mine, after initial installation it was so loose that barely touching the cooler allowed it to twist back and forth on top of the cpu. Not my favorite cooler for the mounting method and one of the most loose coolers I've used.

It's also possible you used too much thermal paste, not sure what you mean by 'covered it well' especially without being able to see it. Here's an idea of the amount of thermal paste to use.

Personally I wouldn't want my cpu running in the 80's consistently as if it's 'normal'.

As you can see, 16-18c is quite 'cool' for ambient room temps and 80c+ is considered 'hot'. Given the difference (ie, hot cpu temps would make more sense if ambient temps were also 'hot') between them I'd consider it a cooling problem.

It sits at 1.25v
