4790K Air Cooler

[maklabouhlel]

Will a Prolimatech Megahalems or Noctua NH-C12P SE14 be sufficient for 4790K @ stock? I already have these?

 

[DragonQ]

Stock coolers are sufficient at stock, so yes.

Will either allow a little overclocking?

duno if i agree that stock coolers being enough at stock
id like to see other peoples temps running stock when doing video editing or running handbreak etc

i guess depends on how good chip too ^^;

The stock hsf is perfectly fine for stock clocks, assuming the case has moderate airflow.

I've built several systems on a tight budget for friends, even during prolonged periods of heavy load during testing, temperatures didn't get above 78dc in my testing.

Bear in mind this was with correct bios upgrades which reduce the stock voltage to the recommended levels - most who complained about the stock cooler didn't upgrade the BIOS, the early bios' on z97 used way too much voltage.

My I7 4790k is under control at 4.4 with a Prolimatech Megahalems but gets a little hot and bothered when clocked to 4.7. I would get a Noctua NH-D15 or a Phanteks PH-TC14PE if you have room in your case, bear in mind that the top PCIE slot on your mobo will probably be blocked with one of these

what was ur testing tho??
stressing all cores mine went upto 90 pretty fast, which kind of makes sense to me as a stock cooler wouldnt be recommended overclocking a 3770k to 4.4 either

my bios was the latest on an asus board, tho cant say i remember them lol

i think for most games you are right but video editing made me change the cooler ><

Seeing as one of the big reasons to buy an i7 is video editing, I really can't see intel shipping these with a stock cooler not up to the job.

If it's not throttling then they're fine with it I guess.

Mine touched 90c at stock with the stock cooler but I have a very cramped case.

personally i think they did, the stock cooler is tiny and its quite a big overclock
tho dave could easily be right too, im not use to the asus bios and maybe i need some voltage help

4790k's come at stock clocks of 4Ghz, they turbo up to 4.4Ghz for a single core workload and 4.3Ghz if all cores are utilized.

This is not overclocking, it's the standard clocks of the 4790k.

Better binning of CPU's enables them to run at this frequency at a reduced voltage, thus producing less heat.

Obviously if you want to overclock to 4.7-5.0Ghz, you'll have to increase the voltage which will drive up the temperatures and require a much more substantial hsf/aio water cooler.

a little pedantic dave without telling us something useful lol

in my experience the stock cooler wasnt good enough at stock when stressing all the cores, you say it is, i only asked how you tested it
maybe your voltage was lower, maybe your ambient was lower, maybe i have a bad chip
teach me something

A stock cooler will be fine at stock otherwise they'd be getting returned under warranties constantly with the shocking airflow a lot of people have and the gunk they let build up. The coolers you listed would be good for a mild overclock.

you say that but what is stock when different motherboards set different voltages, i think asus ones put all cores to 4.4 too unless i was reading it wrong

At stock the VID is set by the cpu, not the motherboard no?

If asus set all cores at 4.4 then they're not running stock.

I don't think intel publish max vid anymore so we do to know what their max vid is but stock is 4ghz base clock and max single core turbo of 4.4ghz you can assume that intel believe their stock coolers are sufficient to stop one of these chips throttling at max allowed vid.

Of course to be truly stock you mustn't be on an overvolting early bios.

I've built quite a few Z97/I5/I7 systems for friends/at work, exclusively with ASUS motherboards. Specifically the Z97-A, Z97-Pro and RoG Hero boards.

With the latest BIOS , they have all followed Intel's specifications of 4Ghz Stock with 4.4 Turbo (single core) or 4.3Ghz across all 4 cores, if all 4 are utilized.

For the builds that I have used the stock HSF, bear in mind I removed the standard gunk that comes on the heatsink and replaced with inexpensive mx2 thermal compound. May explain the lower temperatures, though also bear in mind the cases have been well ventilated with several low rpm fans and the cable management has been very tidy.
