My 4770k 3.5 stock settings, temperatures too high?

Hi. I'm new to overclocking, but I've done A LOT of reading on it, so I feel I understand how it works. So I am doing stability tests at 3.5 ghz at 1.104v on my 4770k using IBT, and these are the temperatures I am getting with 20 seconds of the test.

Im reading all over the place people getting these kinds of numbers after overclocking to 4.5+ ghz. I took out my aftermarket cooler, cleaned off the thermal paste with 91% isopropyl alcohol, and reinstalled it again using artic ceramique 2 and same results.

Im using a coolermaster hyper 212 evo, gigabyte z87 ud4h mb, 8 gb of ram. My cpu cores idle at around 24-26 degrees.

Any possible ideas of what may be wrong?

Nope, your perfectly fine! Your temps are normal for that type of load, and with the hyper 212 you can expect the temps to be even lower.

1) Haswell runs hot when it's overclocked. Significantly hotter than previous generations of chips.

2) While the Hyper 212 EVO is a great little cooler, 4.5GHz and the voltage it implies is pushing it, especially on haswell. (Side note: I would be very, very surprised if you could possibly be reliably stable at 4.5 GHz and 1.104v.)

3) 70c max temps are perfectly acceptable for what you're dealing with - and you should pretty much ignore idle temps as there are SO many factors that go into them... and they don't matter that much. What they're really useful for is telling you if your CPU cooler is seated incorrectly, but it looks like you're fine.

Thanks for the answer, but these are the temperatures WITH the hyper 212 on....

If this is still okay, what kind of temperatures would be considered safe for a stable overclock? I read that max temperature shouldn't go above 80...

Thanks for the reply, I've been wondering whether I installed my cpu cooler correctly.... its good to know that the idle tempatures can be used to determine that. I tried overclocking to 4.3 ghz (using the 4.3 ghz OC profile from the motherboard), and I am getting temperatures a little above 80 from IBT. Is this getting dangerous? or can I continue going?

Oh. Well THAT'S your problem!

Never, never, NEVER use software either in windows or on your motherboard to overclock. It's about the dumbest thing you could do - sorry, but it is. Software always overvolts. Period. Voltage causes heat, so no wonder they're higher than they should be. They aren't dangerous temps yet, but they are higher than you ought to be seeing.

If you actually go learn how to overclock properly (There are some very good guides on the stickies in this forum), and do it manually like you should be doing, your issue with temps will go right away.
