Hi guys, not exactly a serious question here but I just wonder what would happen if I installed some delta fans onto a CPU cooling system. The delta fans I'm on about are 120mm ones which have 252CFM which is massive. If I were to put 3 of these fans onto an NH-D14 with a non-over clocked 4790, would that be the lowest temperature ever recorded? I imagine that I would be able to get some pretty high over clocks with this! What do you guys think? Might try it when I'm older to see if I can get worlds highest over clock with an air cooler lol.

i think that its just unnecessary but regarding temps; the temperature would reach a point but it may not go lower. But about the temperature, well, it will be pretty low like 20 or 15 degrees Celsius ( don't know about Fahrenheit) but wouldn't expect it to go below 0 degrees.

Such fans would allow you to control temperatures created by very high vcore levels in excess of perhaps 1.30v.
Such a cooler would let you damage your chip if used to it's ultimate capacity.
Ultimately, you can't get lower temperatures than 5-10c. over ambient.
All of this assumes, of course, that you have sufficient air intake capability to feed the cooler and it's fans.

Okay so I would get very low temps. if I do this when I have a job I might do some extreme over-clocking then. To get sufficient air in the case, I would probably have 2 of the same fan as a front intake with 1 rear to exhaust the heat. Sounds like a good experiment!

do it directly to the power supply, I don't think there is a fan controller that supports that wattage. Those connectors are 4 pin molex. Also check your 12 volt rails, for something like this i don't recommend using 4 pin molex spliters either.

I would say that it could be safe to connect it to the motherboard because it has a 3 pin connector. Just need to check the mother board voltages in each connector but I rather go with directly connecting to a power supply since its 48 watts.

I reread your original post, and you indicate a i7-4790, not a i7-4790K.
If that is correct, you are not going to be able to do any overclocking at all.
As to airflow, I am all in favor of doing some experimenting.
Two front intakes and one exhaust sounds to me like the optimum arrangement. If the front intakes are filtered, you will have a positive pressure airflow that will keep your case cleaner.
Whoops, I did mean the 4970K. Didn't see that mistake at first lol. Yeah I always want to retain positive case pressure. My first gaming system was a pre-built one in a Zalman case using stock fans only. I didn't learn about case pressure until about a year later. I was sort of annoyed that I didn't add more/better fans because I was cleaning it a lot and therefore using a lot of compressed air!
And lol, I don't actually mind noise but I may have to put it in another room and put the wires under the door. Actually, I know it wouldn't be the best for airflow, but would a Define R5 block out most of the noise? or would it sound like a jet engine?

You say you don't mind noise but I think you're underestimating how much noise one of those Delta fans actually makes !!
The r5 has excellent sound damping BUT using those as intakes is still going to be incredibly noisy.
Switch your vacuum cleaner on & sit next to it for 5 minutes - seriously that's going to be comparable to 3 or 4 of those fans.

No matter how much dampening material is used, those fans are hell on earth. I agree with Both Bossyfins and madmatt, you should maybe consider connecting the intakes to the motherboard and regulate the voltage through there in order to slow them down a bit. I hope your motherboard can stand those fans through the 3 pin connectors. Maybe with that you should be able to reduce the noise of those intakes.
Also try to see if you can DIY and add some more sound dampening material inside the case around the intakes. Maybe that could work too.

Yeah, I will definitely do something to dampen the noise. It's just an experiment so it won't be on all day every day though. I briefly looked on dampening sound and I like the idea of putting thick underlay in the case do dampen the sound. I'll probably have to get the thickest available and put as much of it in and out of the case as possible.

The thing is if you use them as intakes (which is a necessity if your running them internally to cool the CPU as blasting warm case air is pointless no matter the capacity of the fan) then there is literally no way to soundproof them.
They'll shred the foam/mesh on normal filters from 20mm away with a day or two!
The thing the guy said on the video (being as cautious as a cats tail near a rocking chair) is an understatement.
Get your fingers in one of them while they're running & they'll take a ******* chunk out of you.

Dust filters are a trade off.
Do you want a clean case, or more airflow.
On the subject of I7-4790K and overclocking:
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, the consensus is that voltages higher than 1.30 are not a good thing for 24/7 usage.
I have been unable to find any official Intel recommendation on what is a safe vcore limit.
Even if you can handle the heat, how much do you really need that extra multiplier from say 4.4 to 4.6?
