Core i7-3770k temps high after installing Hyper 212 Evo?

I recently installed the hyper 212 evo on my core i7 3770k at stock frequency after some trouble. My temps after 25mins of prime 95 are 47 C from asus AI suite and core temp the temps are 63, 60, 67, 69. This is at full load during prime 95.

Is the cooler mounted correctly and are my temps good for overclocking?

The cooler fan rpm are 850-900.

What voltage are you using? Stock voltage is usually way too high, try undervolting as much as you can without getting BSODs and you should see temps drop. But at the moment they don't look too excessive.

My ambient temps were a bit high in my house. Are those good temps or is the CPU cooler mounted wrong.

First of all download CPU-Z or Open HW Monitor to check your CPU voltage, it has a big impact on CPU temps and for Ivy Bridge chips like yours in particular. Ivy Bridge starts to get really hot over 1.2-1.25V or so. Mounting a cooler incorrectly or missing off the thermal paste will result in 90C+ temps so it looks like yours is on properly.

Just apply a pea amount of thermal paste. also try replacing the fan with another one other than the stock one. like these ones:

I am agree with the previous post. He said very well.

what is the ambiant temperature?

if you suspect that the cpu cooler is mounted improperly, then you can power down your unit, then remove HSF, then clean it with alcohol or your favorite thermal paste remover.
as adviced by previous poster, you can then aply a pea-sized thermal paste to heat sink, then attach the fan and everything else.

also, some say that it will take about 200 on-and-off before the thermal paste is "ready"...

My Intel i5 3450S runs at 36 to 40C. karol3's I7 is not that hot. This is the CPU cooler I installed:

I have tried this, I find the evo much better

Much better how? Of course I've been using mine for over 4 years... no problems with heat

I notice that with the antec I get about 60c, with the evo I get 56, not much of a difference, but I find the evo to look better

I recommend water cooling to any one who overclocks, especially with Ivy Bridge chips, since there are all-in-one kits out there for as little as $60. That's only $30 more than a Hyper 212 Evo, cools much better with less noise, and doesn't strain your motherboard or limit your RAM choices. To me, air cooling the CPU doesn't make sense these days, with so much competition in the liquid cooling area. Prices can only go down, and cooling efficiency can only improve, as the market matures. My H100 may already be obsolete with 140 x 280 sealed liquid coolers from NZXT hitting the shelves. But it still cools great.

But... they only last 2 years... I do not recommend them at all if you are an average user.
