Another 4790k running hot thread

Sadly its down to Intel that theese chips are the way they are. Once you get a better cooler on it temps will be much better. I had one clockked to 4.8ghz, in normal use such as games the temps were mid 60's. Pretty comparable to my previous Ivybridge and Bloomfield 1366 chips. As long as you avoid stress programs with AVX the temps will be fine.

that's cheating m8, you're supposed to stress it aren't you :D:D

because if that's the case mine will hit 4.8 easily, in fact last week i had it stable at 5.1 :confused:
 
Lol, the best way to stress haswell is with normal use, I've owned three haswell i7's, (1x 4770k and 2x 4790k). All have ran extremely hot with AVX programs at stock. Same cooler and fans on all three. Had a 3570k and a 3770k, theese were hot too but not just as bad as haswell. Its the use of cheap badly applied thermal paste that is the main issue.
 
i must admit that nothing will stress the rig like PRIME will, no game for sure, so there's an arguement that sais why bother with it.

yea uum let me go into ``Heaven benchmark`` lets take another look at it
 
the CPU was stable but the GPU was running too hot ! so i've backed off the 7990 to stock and undervolted to 1.12v :(...... interestingly enough it's still giving me the same FPS as when i had it ODd :confused:

cpu is stable right now with prime...... 100% load = 76 degrees at 4.5

but what i'd really love to know is :- what is the CPU loading whilst in Heaven, what is it temps, lets try again

.

cpu is running at 35 degrees whilst in Heaven Benchmark, so that's nothing, the noise is actually coming from the GPU at about 75 degrees.

Prime 95 is therefore stressing the CPU miles more than the GPU is, so if you're playing something like Borderlands 2 then the CPU is probably not doing much ( we already knew this 4 years ago )

so you're right, there's no need to stress test the cpu......only the GPU, this means i can whack it up to 4.7 easily.

Got news from overclockers today.

Surprise, surprise:

Details: Overheating
Status: This item's processing is finished.
Outcome: Replaced


Hopefully no more bad batches. Browsing the internet, a lot of people seem to be having problems with it. Others say it's normal and that you need a good water cooler if you want this chip cold. Wrong!

The truth is, Intel ****ed up with this version; they should have soldered it. Some people are getting normal temps while others think it's okay for them to be that high even at turbo 4.4Ghz. It isn't.

You shouldn't have to de-lid your CPU to make it operate properly. The reason why I'm paying so much money (almost double of an AMD chip), is for them to do the job properly.
 
I agree with you wholeheartedly, theese chips were rumoured to feature better thermals than the previous haswell chips. That was a pork pie from intel. In stock configuration not even high end custom watercooling will help with the temps generated by AVX programs. Hence why you see so many enthusiast users delidding them and replacing the thick gloopy paste applied by intel with coollaboratory liquid pro/ultra. I liken it to buying a supercar and taking it out for a spin, only to find that the brakes dont work.
 
if your not bothered about warranty, smack that cpu with a hammer.
and delid..... it really is awesome, expect 10-15c load drops and even higher on water. :)
 
told you ;)

you either delid it or dont bother replacing it, because your replacement cpu will be the same

the good news is, the Broadwell cpu will fit your mobo, but this is some time yet

what you're saying makes no sense man. There are a lot of people idling at @ 35 degrees with that CPU and stock cooler. Also, overclockers RMA-ed it and said it WAS a fault.

Read the replies and stop talking bs
 
Mal #facepalm

Hopefully your replacement processor proves to be a much better chip. Im also sure over time the 4790K will prove its worth to you.

regards
 
I suspect Mal is meaning load temps with prime etc will still be the same. But 50 at stock does seem iffy, although thats what i got on my first one with a stock cooler. And tbh, it's the first time ive used a stock intel cooler since my first skt 775 E6600 some years ago. So therefore i cant say what theyre like in general.:)

yes but yours was 50 degrees idle, forget all the other CPUs that are ok, because this one has had it's thermal paste badly applied....others might not.

if your cpu was faulty in any other way you'd either get blue screens or the pc simply wont start..... yours was running ok, just too hot

Last update on this issue:

New chip is back. Definitely a huge improvement. Mounted an Evo 212 budget air cooler and the cpu idles at 30-32 degrees (true idle @ 4.4Ghz, not reduced frequency ****), and peaks at 65 degrees in P95 after 5 minutes.

Think I can get some pretty decent OC now, even with this budget cooler.

Thank you everyone that has answered in this thread with useful tips and comments
 
Wow, bit of an improvement there Alex, is that p95 ver 28.5 small fft test. If so you've been lucky to get a very cool runner.

Oops sorry, that was in an older version. on 28.5 it does reach 75 or so.

A note here however: that prime95 test is unrealistic as all hell. I'm getting 55-60 degrees in vegas pro rendering, and 50-55 in heavy gaming (planetside 2 with 200 player battles)
