Haswell Temp Readings

[ThomasS31]

Use the latest AIDA stress test with FPU stress only!
You will be surprised...

Anyway, cleary the problem seems to be that the heat conduct performance between the silicon and IHS is very bad. No matter what cooler you put on, the core temps will be high.
Under stress test its very easy to push haswell to its thermal limits, sometimes even get it throttling (even on stock settings)... and your cooler will be only touchable warm only or cold.

Also as said before, it is almost 100% that this is intentional from intel's side to limit overclock and etc.
Though... wouldn't be easier just simply to decommission the K series.
C'mon intel... what are you doing???

The K series is phenomenal for Intel, it is pure value added to what would otherwise be selling for 36 dollars less or even not at all (in the case of us that wouldn't upgrade if we couldn't overclock).

I actually had no idea what the regular 4770 sold for until I just looked it up. Even if every other LGA 1150 processor was sold for 1 dollar, I would still be buying a 4770k.

What's your motherboard, out of curiosity? I'm not sure why they would decommision the K series when a lot of people are overclocking to 4.5-4.8, pretty much like IB. There's a lot of 3rd party rumors about how bad it is but actual user ownership reports don't seem to reflect the gloom and doom.

Last night, I overclocked my Haswell 4770K to 4.5GHz at stock voltage - although I didn't try to push higher than that. It seemed stable and worked fine, but I will say that it runs really hot (~96C) when I run the Intel Burn Test. That was the hottest that I saw it get though and I did a bunch of tasks - like encoding a movie, and mining bitcoins. I haven't tried Prime95 yet. My motherboard is an Asus Z87 Plus.

I was runnin IBT with AVX - HWInfo reported 140W, and I was getting 106GFlops/s.

^ What is your stock voltage? Also, don't forget that the FIVR kicks up Vcore by 100mV when AVX workloads are fed to the CPU.

It was 1.2-something. 1.225V? Something like that. The VID was 1.1-something. I didn't know about the 100mV increase. Thanks for mentioning it. I was curious why the voltage jumped up so much. I can take screenshots tonight and post more exact values.

Hey guys.

I'm having problems as well with haswell. i7-4970k 4.0
Not OC. Not planning.

I'm getting 90's +c if I stress it with encoding/prime.

I reapplied the artic cooler heatsink(which is huge).
Like 3 times already. And STILL SAME EXact TEMPS!!! .
I was going to test it out with original stock cooler
since thats what my other i5 chip is using.

WHile I set in my old i5 cpu into another mobo, I get
GOOD nice low temps. Stock cooler. Max 65c.

Is there something wrong with haswell or MOBO not
reporting TEMPS correctly??????
While MOBO temps are around 30s???? Even
in my MPC PC temps jump into the 40-50s.

Driving me crazy.

Also I was feeling out the heatsink, was WARM AS WELL!
My 780TI gets realllly hot in the 80s+ normal.
100+f here though.

Know whats funny if a CPU is overheating that high? Would
it not blackscreen, shut off due to temps????
Idles at 40s, seems normal cause of heaT WAVE here.
