I'm thinking of getting the Intel Core i7-4790K. Does anyone know if it runs hot with the stock cooler, without overclocking? Mainly gonna be used for gaming.

More about : intel core 4790k

I would get an aftermarket cooler , the stock cooler gets loud over time.

4790K is a great CPU.

if your not doing any heavy multi thread tasks (coding, audio conversion, or cad work) then there is no benefit to an i7 over an i5 for gaming. I would take the money and get some faster ram, 1600Mhz would be fine or 1866Mhz. You could get 1600 cas 7/8 or 1866 cas 8/9, other then that i see nothing wrong with your builld.

Short anwser: buy aftermarket cooler .

If you can afford a 350$ cpu than i'm sure you can afford a 'normal' 50-60$ aftermarket cooler(at least) , wich of course would help with temps/noise and better overclocking if the motherboard is a proper one. ....than again when we talk about 350$ cpu's i can only imagine you have at least a 130-180$ motherboard.

Based on the build you see above what is your opinion on upgrades?

I was initially thinking of getting the following:


(All are in UK prices)
Corsair Obsidian 350D mATX Case £70
Asus MAXIMUS VII GENE mATX Motherboard £150
Intel Core i7-4790K(4.00GHz) stock cooler £250
16GB Corsair Vengeance Pro 2400 MHz £162

What is your opinion? I said If I'm gonna upgrade I might as well go over the top. My motherboard is old and my pc in general has no expandability, also I'd like the added benefits of improved airflow in my case. Based on my pc specs as listed in my signature what is your overall opinion?

Can you please specify the particular model, cause I'm having trouble finding them in the UK stores. Also do you consider the 4790K a big improvement in gaming over the i5-3570K? (based on what real world requirements games need for the following 2-3 years)?

Your build is similar to mine, check my sig.
Love the maximus vii gene. More than I need but a beauriful motherboard.

I have become a bit jaded on the subject of haswell cooling for overclocking.
How high you can OC is firstly determined by your luck in the bin lottery.
I had high expectations from the Devil's canyon parts and their better thermals.
I found out that the thermals really do not matter unless, perhaps, you are a competitive overclocker.
Haswell runs quite cool, that is, until you raise the voltage past 1.25v or so.
Once you go past 1.3v, then you really do need very good cooling to keep stress loads under say 85c.
But, voltages higher than 1.30 are not a good thing for 24/7 usage.
Even if you can handle the heat, how much do you really need that extra multiplier from say 4.4 to 4.6?
My thought is that it is better to use the exotic cooling funds for a quieter and less expensive air cooler.
Anything extra can go to a stronger graphics card for the gamer or a SSD.
I ended up using a noctua NH-D14 which is very quiet.
If budget were an issue, a tower cooler with a 140mm fan from noctua or Phanteks would do.

I bought g.skil tridentx 2400 ram. It was somewhat of a mistake. I had to remove one of the gorgeous heat sink spreaders. 1866 low profile 1.5v ram would have done just as well.

On the case, I like the 350D. I can also recommend the Silverstone TJ08E it keeps everything cool and inaudible with the front fan on low and undervolted.
The PS07 case is similar, and even quieter.

Thanks for your reply. I already have a Seasonic M12II Evo 620 Watt and an MSI GTX 970 which I purchased 3-4 days ago and I plan on using them in my build. Also I have a Kingston 60GB SSD and a 500GB HDD which I plan on using. However what do you think about a Haswell i7 vs an Ivy Bridge i5 for gaming? Am I going to experience a big difference in performance when gaming?

Big difference... I think not. Graphics is the most important component.
But I would go with newer tech always. The i5 4690K is very good.
What you get for the extra $100 you pay for the 4790K is a better binned chip and hyperthreading which is not much help for the gamer. If $100 is not a big deal, buy the 4790K, otherwise the 4690K.

I would not bother with a 60gb ssd for the "C" drive.
such a size will fill up quickly and as it gets full, it will lose performance.
I suggest at least a 120gb ssd, and preferably a 240gb ssd. Use the 500gb drive for bulk storage.

So the 4690K would grant me noticeable performance when compared to my current 3570K? Also would it be future proof for say the next 2-3 years?

If you already own a 3570K, there is no compelling reason to upgrade to 4690K you are looking at perhaps a 10% benefit when each is overclocked decently.

In games, it is the graphics card that will be the limiting factor in either case.

If you do not already have a 3570K, and are looking at buying new, then pay a bit more for modern tech 4690K.
With a Z97 based motherboard, you will be compatible with whatever 14nm broadwell brings next year.
I suspect that will be in the 10-15% improvement and possibly better overclocking headroom.

I already have an i5 3570K but will be upgrading my motherboard so I need a CPU with the same or perhaps slightly better performance. I might overclock in the future as well. Will a 4690K do or should I go for a non-K model?
