Is something wrong with my processor?

Some motherboards like to run the 4790k at 4.4GHz out of the box. That's something the stock cooler can not possibly handle.

Some motherboard also overvolt the 4790k a bit. That's ok with an aftermarket cooler but the stock cooler will again probably be insufficient if that's the case.

Just so you know, core voltage for the 4790k should be about:
under 1.08 at 4ghz
under 1.18 at 4.2ghz
under 1.25 at 4.4ghz

Proper way to make sure your CPU cooling is adequate:
run a stress test that puts full load on your CPU until temp stabilizes (should take just 2-5min)
I prefer OCCT but it's possible to use others. I don't reccomend prime95 for haswell.

And use a tool like realtemp to monitor the temperature of each core in windows. I don't recommend using the bios since a lot of motherboards use a sensor that's placed near the CPU and not in the CPU itself

An easy way to lower temps might be to turn of turbo boost in the bios.

So we're going to ignore that his voltage is probably still high? OP hasn't posted the CPU voltage under loads. My 4790k wasn't hitting 70c with the stock cooler even with BF4 running.
 
I would say voltage set by motherboard is likely high, or....
Being an Intel stock cooler, the paste could have dried before it got to you and it just needs new paste.
However, the stock cooler should hold stock clocks without throttle, which makes me think the cooler is not clicked in on all four corners.

Find some thermal paste, brand doesn't really matter for this, pull the cooler, and after cleaning and applying new paste, try installing it again and be sure to listen for the audible click as the posts lock into the motherboard.

YouTube has some good tips for installing it, and I know LinusTechTips does videos for installations. Hell I even watched one of his videos for installing the stock cooler.

Same guy, different channel.
 
Ok, I've got basically the same setup as the OP(motherboard and CPU). Some points:

  • XMP has no real affect on the CPU. It is a memory thing. So turning it on/off won't really affect CPU temp.
  • The Z97 Extreme6 doesn't overvolt the CPU by default, at least not on the latest BIOS. It did on the early ones, but not as bad as some other boards. It set the voltage at about 1.2v and didn't idle down the voltage properly when the CPU was idle(that is why a lot of the reviews for the board had higher than average power consumption under load).
  • Turbo works a little differently with the 4790k. Under full load it will only boost to 4.2GHz. This is NOT a sign of thermal throttling, that is just how the boost works with the 4790k. It will only boost to 4.4GHz when 2 cores or less are loaded.
  • When I ran my 4790k with the stock cooler on my Z97 Extreme6, temps were about what the OP was getting. That is why I asked if he was using the stock cooler. Intel really designed the CPU and the cooler to operate right on the edge acceptable temperatures. The fact that TJMax on Haswell is 105°C allowed them to do this. The chips can handled a little higher temps than before.
  • The stock cooler just sucks. It is enough for stock speeds, but just barely. I guess it saves Intel 3 Cents per CPU this way or something.

Correct the stock cooler sucks and its easy to miss align. I'm sure that's whats going on.

Two thing I don't like about Intel
1) Stock coolers
2) CPU pins
 
Reading the Intel manual will work as well.

That is how I did it.

What Intel CPU have pins on the CPU? The newer models I know are all on the motherboard which is safer because the CPU usually costs more than the motherboard. And it is much easier to bend pins on the CPU itself.

I did not have any problems with their cooler. It is as easy as 1, 2, 3 to install.

How does one do this. I jiggled the cooler around until I felt each "pin/tab/plastic" thing was in a hole, and pressed down in an X fashion. I can tell you now that AMD heatsinks bake better than Intel heatsinks, so there is a negative to Intel.
 
you can remove the plastic pins on the stock intel heat sink fan and run a set of bolts with nuts and washers instead.

Its the white tab going threw the hole. It need to be seated. If the hole is a little tight the tab does not seat and click its not aligned. Sometimes you have to take a small screw driver and seat the white tab before you push down on the black knob

Its a bad design. But your correct jiggling works unless the hole is tight

Anyway buying a 212 fixes everything
 
Hey guys, thank you so much for all your replies. Looks like I'll be buying a new aftermarket cooler for the CPU. :)
And I'm looking into it right now.

Although some important questions beforehand:
Because I live in a backwater country called australia, with the nearest computer store being 50 minutes drive away.
I'm going to bring my computer case there and let the store staff assemble it for me. (since I really don't know how
and online delivery for the cooler isn't much cheaper anyway)

What I'm wondering is, because the store have some benchmarks, I'm going to let them run it for a few hours in store,
including FurMark, Prime95 and XTU. I'm wondering what sort of temperature should I expect after the aftermarket cooler
have been put on? Such as idle/load/peak temps for the different components with the different utilities.
(say if the Cooler Master Hyper 212 EVO was put on)

Since it's better to know beforehand and let any problems to be fixed in the store, than find something wrong and bring
the whole case back afterwards.

By the way does aftermarket coolers come with thermal paste or do I need to buy it separately?

Also should I purchase more case fans? I'm only using the default 2 that came with my case (Fractal Design Define R5),
which is 1 in 1 out. Do you guys recommend to buy more case fans as well to help with cooling?

Sorry for these questions if it sounds silly, this is my first time building a system and I'm literally learning everything
from scratch.
 
Also importantly, what are the differences between the Cooler Master Hyper 212 EVO
and the Cooler Master Hyper 212X? Which one is better?

Since my store doesn't have the 212 EVO but only the 212X.

I've looked at this website:
http://au.pcpartpicker.com/parts/cpu-cooler/#qq=1&R=5,4&w=0&sort=d3&m=50

The 212 EVO seems to have crazy amount of good review compared to any other coolers on the market,
with 5 star rating. But the 212X only have 4 stars and not many bought it.

Does it mean the 212X is an inferior product compared to the 212 EVO? Funny that it also costs more.
I could try purchasing from other places online and have it delivered if the 212 EVO is a better product.

Also any other good ones that you guys wish to suggest? :)


Lastly this thing really have me worried, because I've ran some of those stressful benchmarks before and
frequently stayed above 100°C for several minutes, even off the chart. Have I damaged or reduced the
lifespan of my CPU or any other components in ANY way?

I'm really scared that I did something wrong which harmed my new system, since it really cost me a
fortune to buy it, been saving up for many years.

Thanks again for all your comments, really appreciate them!
 
I would run my own benchmarks and not let the staff in a shop miles away torture it for their own amusement. :eek:
 
@sapped1
Given the fact that you have purchased a top of the line overclocking cpu (which is absolutely unnecessary for gaming), I'm assuming you are more interested in having fun with overclocking. If that is the case, then for optimal results you should consider a AIO water cooler like the Corsair H105, CM Nepton 280L, Swiftech H220X etc. If you do NOT want very high OC, then settle for CM 212 Evo or Noctua NH L12. The later is very easy to install and runs very cool and quiet, and is of outstanding quality. I would suggest the Noctua, since you seem to be new to all this, and it will give you less trouble during/after install. JJ from Asus did a very comprehensive video about how to go about all this (and a lot more), which shows exactly how to do it. Watch it and enjoy the DIY PC-building experience. Good luck!
Here's the video:
 
Hey guys, thanks again for all your feedbacks. I've given more thoughts about this today.

Sorry that I didn't mention this before, regarding overclocking the CPU. My original plan was to
overclock that processor only after 1 or 2 years, since the games and processing tasks today does
not require that much high frequency. So I'll only start considering to OC when I actually needed
that extra speed. Was originally considering to buy an aftermarket cooler only afterwards, and stay
with the stock intel cooler in the mean while.

However it turns out that the stock cooler is already a piece of **** like some of you said. So I'll
need to purchase an extra cooler anyway. I might as well purchase a good one now right? And maybe
start overclocking 1 or 2 years later when games gets more demanding.

Although I'm wondering does CPU coolers work this way? How long does one usually last and do I need
to switch it out with new ones in any set period? Since this is really a whole new world that I'm
not familiar with and trying to learn. Would it be better to buy a cheaper one now and buy a more
expensive one later on when I actually starts to overclock?

I think the highest frequency I'll go with the 4790k is 4.7Ghz, I wanna ask will the Cooler Master Hyper 212
be sufficient enough for that high frequency? Or do I need to look into more expensive price range?
If so how much, the Noctua NH-D15 seems like a good one from this list, will this be sufficient?

http://au.pcpartpicker.com/parts/cpu-cooler/#sort=d3

Also just some general information regarding CPU coolers, does faster fan RPM means it's better at
cooling and dissipating heat like it normally does? Or are other factors taken into account as well
like qualities etc. And would you guys recommend buying liquid cooling compared to air cooling?

Sorry if I'm asking so much questions, I'm totally new at this. Building that PC in the first place is
already a great enough challenge for me. I'm really overwhelmed at the moment so appreciate any help.

Depends on if you get a all-in-one water cooling unit or a heatsink. If you are worried about longevity, I suggest a heatsink. Worst case scenario with a heatsink is a fan stops working, which is easily and inexpensively replaced. With a AIO water cooling unit, if the pump goes bad, you have to replace to whole unit.

The 212 is not going to be good enough for a 4.7 GHz OC. The NH-D15 is a very good choice IMHO. I had a NH-D14 on my 2600k OC'ed to as high as 5 GHz, the D14 handled it without any problems.

Also just some general information regarding CPU coolers, does faster fan RPM means it's better at
cooling and dissipating heat like it normally does? Or are other factors taken into account as well
like qualities etc. And would you guys recommend buying liquid cooling compared to air cooling?

As far as the fans go, RPMs don't matter nearly as much as CFM (the amount of air that is being moved by the fans). Higher the CFM rating, the better the fans will cool the heatsink.

As far as the heatsink goes, look at the number of heatpipes it has, and the amount for cooling fins on the heatsink, the more, the better for cooling.
 
CM Hyper 212 will be fine for moderate overclocking. For 4.7GHz though I feel it might not cut it, so the more expensive Noctua might be what you'll want.

About the fans... RPM doesn't mean too much. Higher RPM (revolutions per minute) means the fan spins faster and thus moves more air, but will be louder. But this doesn't mean fan A @ 2200RPM will be better than fan B @ 1800RPM just because of the RPM. There's a lot more that goes into it. You generally want to look at CFM (cubic feet per minute, how much air the fan actually moves), but even that can not be so much of a big deal for different applications. There is also static pressure. A higher static pressure would be good for pushing air through something dense (thick radiator) but not so important for a typical air heatsink.
 
I still cant figure out why after doing so much of your build you would feel the need to take it to a shop to get the heatsink fitted?

Once they have fitted it they are then going to stress test it for you.

If you have gone this far you are probably as knowledgeable as the kids who do it for you.

Get the best one you can afford and follow the advice and suggestions the members have offered you. From your posts you seem very knowledgeable and confident/competent.

My nearest pc shop is 90 minutes return journey.

It only takes me a click to get to TPU

Looks like I'll be buying the Noctua NH-D15, read so many amazing reviews on this.
That CPU is literally the most expensive component in my machine, so might as well
treat it with something good, and also opens up much possibilities later on. :)

Also just read some of the horror stories regarding water coolers bursting, so think
I'll be skipping those, especially when the machine is supposed to last for many years.

Anyway back to the original question, what sort of temperature should I expect with
the benchmarks after the new cooler have been mounted? I've rang the store and asked,
they told me I can bring any benchmark and stress testing tool I want.

You guys mentioned Prime is not recommended (at least the latest version), so think
I'll be using XTU. How should I run it and any other tools to recommend?

And what temperature range should I expect with the CPU (with non overclocked frequency)
after the new cooler has been mounted by store staffs? So any problems can be fixed on
the spot in store.

Such as the idle/load/peak temps for the processor and also other components as well.

Cheers guys, would not have gotten so far without your guidance and dedication, just
wanna say how much I appreciate all your help!
 
No higher than 80'c, probably more like 70'c. Just depends on what software you use. Personally, I like just running the Bionic crunching program(click the blue WCG cruncher tag under this post for info). It will push your CPU just as hard as it can and will use every processing thread your CPU has, meaning 100% full load. My 3930k (6 cores/12 threads) OC'ed to 4.25GHz runs between 70-80'c with this heatsink running Bionic - http://global.gamerstorm.cn/Product/Assassin/

Thanks BarbaricSoul for your comments, I'll download the WCG cruncher and put it on my system.

between 30-40' c is average for good idle temps
 
amazing review on DH15 and above average price ... yep a awesome heatsink, not the king of perf/price ratio tho ... many other do better on that point and cool just as same as the DH15 :D (and look better and have a better bundle ... etc etc etc ... )
humpf i can't stand Noctua ... (tho they are good ... but they charge too much o_O imho )

one of the good example of a excellent rival to a DH15

WCG is not a stress test it's a World Community Grid it use your computational power to help on research ie: AIDS Cancer and such (altho it put a heavy load on the CPU, that's a granted)

my guess is you expect too much... wondering about temps higher than you seen while having a stock cooler, expecting idle temps
but for idle temps for reference my 4690K run @ 30-34° idle, max temp 56-58° but it's under a water loop and no turbo or speed step active (yep i know stupid to run my CPU permanently @ 4.690mhz )

i tested quite a bunch of heatsink dual single tower 140/120/90mm AIO (mostly 120 single/dual fan setup)
