What's a good OC to shoot for with a 4770k and Hyper 212 EVO cooler?

Mobo is MSI Z87 G45 and the ambient temperature should be about 25-30 degrees Celsius this summer. I was thinking 4.2 would be safe but I'm not totally sure since this is my first time OCing. I don't really wanna de-lid my CPU either

4.2GHz is pretty conservative. Try to aim for the highest you can get with 1.25-1.3 Vcore. This could be anywhere in the 4.3-4.6GHz range.

Even at that high of an ambient temperature? My rig has an intake fan (200mm) and two exhaust fans (one 120mm and one 200mm) but it's still only air cooling...

my 3770k is at 4.5ghz with stock cooling and no problems at all so im sure you'll be fine at atleast 4.5ghz

30C
High Ambient Temp

Pick One

Also Ambient Temps mean absolutely nothing, you need to run IBT on Very High for 10 runs and see your temps.

Yeah just keep track of your temps. You may have to stick closer to the 1.25V limit to stay under 90C in tough stress tests like Prime95 and LinX. The main determinant of CPU temps is the voltage so basically just try to get the highest clocks with whatever voltage allows you to stay under 90C.

Ambient and idle don't mean the same thing.

Not every 4770K can do 4.5GHz with a voltage low enough to work with the 212Evo. I'd say maybe only 40% of Haswell chips can reach 4.5GHz at under 1.25 VCore based on the statistics I've seen posted online. Also Haswell runs 10-15C hotter than Ivy Bridge.

I know, but still that's not even close to high.

I think ~85 degrees Fahrenheit is pretty hot >_>

30C is incredibly high for an ambient temp. Generally most people like to live in the 20-23C range. Usually 30C means the AC needs to be turned on.
