Overclocked i5 4690k Temps with Prime95

i5 4690k is overclocked to 4.4Ghz with a voltage of 1.25

My CPU cooler is the Noctua NH-D15.

Idle temps are rougly 34-35 C

However my biggest concern is during Prime95 tests. During a blend test, the first five minutes look good, averaging around 50 C. However as soon as test 2 loads, my temps shoot way up, hovering around mid 80s and maxing at 90. I ran the test for an hour and it didn't find any problems, but are these temps concerning? I'm pretty new to this whole OC thing, so if anyone could help me out her I'd be thankful.:)
 
Prime95 stresses way more than normal heavy use, try gaming or something and checking temps.

If you are worried, I would bump it down to 4.3 to be safe
 
that does seem like quite high for a dh-14.

running to 80-90 wont cause damage for one off runnings (benchmarks etc) but it should be kept well below this for normal running at a max of around 70c. Ive ran mine over 90c before (5.2ghz) but not much over. Intel suggests it doesnt go over 92c or something like that so i would back off the overclock a little.

Also running games is quite a bit different, mine runs like 45-50c on bf4 at 4.6ghz. but will run slightly hotter on prime 95 at around 60-65. its only really encoding, compressing etc that will give you similar temps to prime 95 which is why i run 4.8ghz for games and 4.6 for editing etc.

yea prime95 is NOT the recommended program for cpu stress testing anymore. while it will give an absolute worst scenario ... it is also known for pushing things like turbo boost and even causing a lot of different problems with voltage, giving really poorly skewed results.

aida64 is the one linus uses and honestly, i recommend doing some gaming as mentioned before. that is really odd for a 4690k though as it has the better tim under the ihs... meh if you continue to have problems i'd return it. even newegg has taken my rma before because i had a 4770k that was reaching 90c at stock clocks, on a corsair h110. got a new one and it ran 30c cooler. so random
 
The problem with Prime95 is that it can actually pull more voltage than you set in your BIOS - afaik.
I recommend OCCT 4.4.1 with any AVX compatible CPU. Using AVX Linpack will stress your CPU much more than it ever will be in real scenarios.
My CPU can take more voltage than yours, but I'm running 4.4GHz at 1.275v with a D14, never breaching 65C - but with OCCT it reaches ~80C
PS. I have my D14 hooked up to a Molex -> Fan adapter -> 12v->7v adapter, so it's always running at low RPM
 
On my 4700hq I idle at 53c and regularly hit 78-84c topping out in the most demanding games. Thats on an Alienware laptop though, and I've replaced the thermal paste. Before, I often hit the thermal maximum before it throttled. Baad, bad bf3 deaths ensued and a few rage quits.

That's not the best hehe... My laptop also hits the 80's when gaming... But mainly because laptops have bad airflow. I purchased a cooling pad with 2 fans to just push air somewhere, and my temps dropped about 15°C

The Alienware 14 has good cooling, but it's hampered by small size. If I had a cooling pad, I might get the same drop in temperature. unfortunately, I don't expect too much, since my gpu is overclocked past the 800mhz stock clock to 1176mhz, and the memory up from 4ghz to 5.. The 765m overclocks like a beast! :D
