Haswell overclocking temps

I was wondering how high is too high for full load temps on a haswell cpu? I over clocked my 4770k to 4.6ghz @ 1.2 volts full load seems to be at 89-90 degrees and and idle around 30-35. Im also using an h110 too cool it.
 
Solution
The H110 is not really capable of handling OC on Haswell very well. It did "ok" on Ivy. You want lower temps? you have 2 options (de lididing is a 3rd, but not really necessary and a bit advanced for most, and useless if you don't have a cooler that performs well enough anyway)

1) Tested top end air coolers for haswell performance levels: Noctua DH-u14s, Thermalright Silver arrow extreme, Phantek pe-tc14 all outperform h110 even on ivy! O, and they are quieter. O and they are cheaper. (100-125usd)

2) custom water build designed for performance (300usd cpu loop). AIO coolers are a sorry excuse for advanced OC performance cooling. Mid grade cooling sure... Upper end - hell no.

brought it down to 4.4 and it hits 77 degrees at 100% load

I think the temperatures are accurate. Haswell runs really hot. Way hotter than Ivy Bridge. You are not the only one having high temps with Haswell.

But I'm surprised the temps are not higher. You did quite a high overclock without adding voltage. From what other people have done, you should have gone around 100°C.

Your CPU may be throttling down to stay at 80°C.

from what i read im apparently the lucky 10% and do you know possibly what temps people usually have the haswell running at max load?

There was a thread a few weeks ago where someone was hitting 100°C under load at stock with an H100.

But, from reading around, it seems that 80°C and above under load is normal.

Nothing you can really do about it. The chip itself runs very hot. If you delid your CPU and replace the TIM, it will run a few degrees cooler (there are a few videos on YouTube that shows how to do it).

But its risky and can damage your CPU permanently if not done properly. You can lower the speeds till it hit correct temperatures. You will still have a lot more of processing power than you need if you are gaming.

Another thing you can do is save some overclocking profiles in the UEFI. Save a few overclocks and run it at a speed where it runs cool for 24/7 (or even stock, whichever you want). Make a profile for a mild and another for a high OC. Whenever you need it, you just have to restart your PC and activate a profile depending on your needs.

well that was money well spent. I guess ill keep it at 4.4ghz and not touch it because the temps at full seem to be fine.
