Extremely hot 4790k

[ForzaPC]

I build my new computer >>http://linustechtips.com/main/topic/182093-build-log-black-gold-mini-gaming-rig/<< and I'm seeing very high temperatures with my 4790K. I had a H110 on it with Noctua NF-A14 FLX fans but when running Prime95 the temps went through the roof after a few minutes (96 degrees). So I thought the H110 was broken. But this morning I installed the standard cooler and when running Prime95 the temps go straight up to 99 degrees and the cpu downclocks to around 3.5-6. Shouldn't it be able to run at atleast 4.0 with the standard cooler? Would this mean that the cpu is at fault?

With haswell refresh, I think running Prime95 is bad. It may still be altering the voltages giving you crazy temps. Try using Intel burn in and see

Please turn off adaptive voltage before you kill your chip while stress testing.

 

Use Aida64 or OCCT

This. Prime95 and adaptive voltage on haswell CPUs is a horrible idea. My 4670k was set to 1.2V and with prime95 it went up to 1.38V!

Haven't looked into the voltages at all. Before returning anything i'll go ahead and set voltages manually.

 

What would you guys recommend ... let the Noctua's suck in air through the top, or push out?

i had the same problem mine was a bad chip this was my batch number L4198610 new egg warranty it right out for me thanks newegg!!!!!!!!!!

Shouldn't it always be pushing out?

 

Hot air from the case will rise to the top, so your case fans on the top of the case should naturally be exhausting air outside

 

Probably best to let the fan on the heatsink suck in cool air from the bottom and push it through the fins so it goes out the top

Remounted the H110 with new thermal compound (Gelid GC-Extreme). Set the multiplier to 44 and the Vcore to 1.2 volts, when testing with OCCT the cpu reaches to just below 80, but is generally between 70 and 75 degrees.

 

Thank you all!!

 

Now the fun starts with getting as much as possible out of it  . I could use a good guide for overclocking the Devil's Canyon, so if anyone found one, please share  .

Overclocking Devil's Canyon is exactly the same as with Haswell, so just follow one of those guides (there is one on this forum).  

While validating your overclocking, use manual voltage only, and then once you have something stable, you can set up adaptive voltage for 24/7 usage.  

Also, for a nice, stable overclock, set your load line calibration to something in the middle range of what your motherboard allows.  (See my sig for more details)
