4790K - getting 88C on stock cooling in Crysis 3.

[CP5670]

The 4790K's temperatures go way up when running AVX2 code. Apparently it's designed to have an automatic 0.2V bump when running this code. I don't think Crysis 3 or any other current game uses that though.

I use a Noctua NH-U12P with a 4790K. It tops out around 65C in IntelBurnTest and 60C in most games and regular programs, but goes to 100C under AVX2 programs like Prime95, even at stock speeds. I haven't used the stock cooler, but it's very small (smaller than the one my old 920 came with) and looks totally inadequate for these processors.

The bump is 100mv. Its associated wth the cache that doubles in speed.

After reading the Intel thread, before I bought my 4790k (that is waiting to be fiddled with), the common setup option missed by the boards was setting the total thermal package to 130 watts; or something like that.

So the *motherboards* are actually over volting the chips by default.

The FIVR has changed how these behave / tweaking options, compared to Sandy and Ivy.

Yep I am guessing the same thing but what about when people are using them on a z97 instead of a z87? I think with the newer chip set and bios the manufacturer would have had fixed any auto over volting done by the motherboards.I remember motherboards doing this with going from p35 to p45 would auto over volt chips when they clearly didnt need to be. Although this was fixed early on through a bios update shortly after the q6600's release. Ahhh those were the days LOL. Anyways maybe look into a bios update and dropping the volts cause there is no reason a 4790K needs 1.25 volts to run at stock settings.

Yes. It used to be that "some" boards would adjust the voltage in the sandy/ivy era. Now overvolting is the standard for this chip/chipset. In the case of my board, the volts given when overclocking are not much more than the voltage needed for the selected speed (I remember my Gigabyte Z68 giving a good bit more voltage than the chip needed when overclocking/ voltage on auto).

Newegg.com has Zalman Pure CNPS14X Aluminum High Performance CPU Cooler w/ 140mm Fan on sale for $49.99 - $20 w/ promo code EMCASAK33 - $20 rebate= $9.99.

Intel Core i7-3960X ES @ 3.6 GHz & 4.1 GHz OC (Sandy Bridge-E)

Beats the 212 Evo by 13*C

If you don't mind the noise at full fan speed, there is no cooler at $10 that can even come close to this one. The next level up is the True Spirit 140 and that's $40.

There you go, $10, mounting it properly and your problem is solved. / Thread.

Anyone, please see sections 5.1 thru 5.6

Especially 5.4

I do not think this is all just a crappy cooler problem.

Straight from Intel.

Short edition is, mobo makers cut corners as usual to look better than the other.

MCE was a huge blunder last time.

In regards to 5.4:
Is this a surprise? AMD has been doing this since 2012. Intel a bit later, 2014.

Can you tell us what exactly you are trying to draw attention to? The datasheet covers many facets of this CPU family.

 

[Puffnstuff]

You should just spend a few bucks and get an aftermarket cooler and your 4790k will be fine.

Look at my second post after that, #32, that covers my point.

 

[lyssword]

yeah thats pretty normal, running 4-4.4ghz ht-quad is no easy thing to cool

You haven't made your point. Post #32 reads "Straight from Intel." I could guess what your point is, like "Update your BIOS" or "Disable XMP" but those are Intel's points.

 

[crasherkid]

Absurd temps!

Ya, let's divert the attention to mobo makers and ignore that Haswell's TIM is implementation is cheap junk and the stock Intel cooler is paperweight for anyone who actually uses their i7 4790K processor how it was intended - you know full load on all 8 threads. Also, your comment completely ignores that high temps of i7 4770K/4790K CPUs occur on all motherboards once the load is significant enough. You might have 100*C on an Asus board, 93*C on an Asrock board, 88*C on the MSI board, but generally speaking it will always be high due to the nature of the solder-less heatspreader design because Intel decided to save $0.25.

Thankfully Intel's i7 4790K is rated to 100*C. Even when CPU temps hit 100C 20% of the time, the performance drop is only 2.5%.

As already mentioned by other posters, this is nothing a $10-25 after-market heatsink cannot fix, but technically 88*C will not kill the i7 4790K and won't adversely affects its performance that much.

 

[iiiankiii]

Is there any way to prevent AVX 2 from bumping up the core voltage? That would be extremely helpful at keeping the max temperature more predictable.

*rubbish*

You obvious didnt read the link.

Even tho the tame sheep will always believe what intel tells them, proccies are intended to be used with all the instruction sets they suppprt. If intel cheaps out on TIM its their fault for the high tems under FMA in prime95 28.5. Its rubbish to think that you cant use this software because intel is that incompetent making a half decent stock cooling solution. So now we cant use multithreaded software that uses FMA because an intel website says so, rofl.

Btw prime blend 28.5 makes my 4790k at 4.0 and 1.01v consume about 83w with the intel gadget. You are telling me the stock intel solution cant even dissipate 83w worth of power consumption without reaching 90c? This only tells how rubbish intel stock cooling is, nothing else.

Im planing to adapt a better stock cooler made by intel (core2d/presler era 775 bifurcated fin, copper core stock hsf) it has thrice as much fin perimeter, its twice as deep and has a higher rpm 90mm fan. Im going to compare it with the crappy 1150 copper core one. My assumption is it will obviously outperform such garbage, the thing is by how much.

My mental image of a decent stock cooling solution would have been soldered hsf plus this 775 cooler. The closest i can do would be a delidded 4790k with better tim or clu between the die and the hsf plus this 775 cooler. THAT should be the bare minimum intel should ship their $350 chips with.

The stock cooler is sufficient for the i3 (just) and below. Interesting to see if Broadwell changes this.

The stock cooler is great on my Xeon E3-1231v3. I can't hear it and my temperatures peak at 61C while gaming even now as we're entering summer in Texas.

Haswell chips must be out of this world for power consumption.Constantly hit over 70 on my 3770 non k on all threads in games like BF3 .What games are you playing with those temps?

DC OC is not quite the same as Sandy and Ivy, Intel wants the TDP to be taken into account first.

Keep nitpicking, I am trying to help someone who has a common problem with DC setup; the boards are way high on initial running specs, and need attention, that I linked in my second post.

Yes, a new cooler will help also.

So, unless you want to do some Googling and help another enthusiast out, chill out.

Edit: I wouldn't be here if I didn't do some research before grabbing one...

I am sure the stock cooler is bad, and Haswell does run hot. However, if 88C is the highest you ever see, I dont think I would worry about it. Now if you see even higher temps in other uses, or if the noise of the stock cooler bothers you, that is a different matter.

61C was my max temperature running Crysis 3 on Very High system spec for an hour or two. Similar temps on other games like Dying Light, Shadow of Mordor, etc. Supposedly the Xeons come with better quality fans than the i5/i7, but the heatsink is exactly the same one as came bundled with my Pentium G3258. When running Prime95 SmallFFT for a few hours it'll run mostly high 70s with rare peaks up to 81C on the stock cooler. This is also set on the high performance preset in Windows 7, which keeps the CPU running at the 3.6GHz all cores turbo or higher at all times.

I have heard Haswell is just all over the map when it comes to temperatures though, especially the original Haswell chips before the refresh.

This. 88C is not a temp this CPU will even throttle at, so no worries. It would throttle on the latest prime or OCCT, but that is the type of load you are not going to see with current programs/games.

I did, and I did (also see post 29 if you wish), thanks.

I had to use the stock cooler for my i5-4690k for a couple weeks. It got into the low 60's for gaming but that was due to being at 4.0 GHz with stock voltage; not 4.4 GHz like your i7.

If stuck using the stock cooler I'd probably make it so the i7 hits 4.4 on only 1 core, and 4.1-4.2 GHz if all threads are under load.
