Upcoming LGA2011-3 build, cooling questions.

Kevinsweijen · Jul 10, 2014

Hi TomsHardware community!

First time builder (not a complete noob, I know my hardware

) and decided to go high-end on this build, basically what I'm gonna get:

i7-5930K (This will be OC'd)
X99 motherboard (probably that sexy as hell MSI mobo with USB 3.1 on it)
16GB 2133MHz DDR4 RAM
Sapphire R9 290X Tri-X

That's what's for certain at the moment.

So, this'll be a hot system. According to a friend I'd need 4 120CFM fans to cool this correctly. Which'd end up in a noisy system...which isn't an option as this'll be in a living room.

Therefore, I come to you, lads., my questions:

1) If I were to do this on air, what kind of fans would I need for a cool, yet quiet system?

2) Liquid cooling! I know next to nothing about it, so if you could put together a not too expensive, but efficient system for me that'd be great.

3) While we're busy anyway, let's pretend money isn't really an issue, what would be the best LC system you could recommend me?

Note: My ambient temperature is at a steady 18 degrees Celsius.

Thanks in advance,
Kevin

Not sure where your friend gets information, but it is more about configuration then a given number of fans. If you have a well managed and open case then one or two vent fans spinning quite slowly and noise free is all that would be required.

Speculating on a theoretical system is difficult. You haven't specified case, motherboard size, power supply, drives, etc. Closed loop liquid coolers are easy to install if you have the space in your case. Custom liquid cooling really depends on your case and what drives you want to use. Many pumps/reservoirs end up in the 5 1/4" bays and radiator size is dependent on what you are putting in the loop. One or two video cards, a CPU, the motherboard, ram (sometimes)

When the parts are available and there are water blocks for all of the parts you want to use, then you can look into custom loops.

Air cooling should be relatively simple though. Some of the larger Noctua products would be the best available for cooling the CPU. Plenty of video cards out there with good air cooling solutions. A case with top exhaust and some intake up front and some high static pressure fans and it would be a very quiet system.

Eximo :

Thanks for the quick reply mate.

PSU is a CX750 from my old PC. Storage will be a 120GB Samsung 840 EVO and a Samsung 2TB HDD (Don't know the exact model number, was an OEM drive).

Haven't decided on a case yet, since I needed to know what I was gonna put in cooling-wise.
You reckon getting an NZXT 530 and then filling it up with Nocyua fans, with the correct config ofc, will keep everything seriously cool? And since I'll be OCing, liquid cooling on the CPU or shall I settle on a Noctua NH-D15?

The case beyond a point contributes nothing to cooling performance, and that point tends to be all of them. I wouldnt be stressing too much about how the case will affect temperatures unless your going for something silence optimized (inherently has lower airflow).

A CLC like a Corsair H100i performs the same as something like the NH-D15, its more a question of which you prefer. Liquid cooling isn't inherently better than air, CLC manufacturers are relying on the Halo Effect from custom water-cooling (which performs far better than air unless you stuff it) to give the impression there stuff is better.

manofchalk :

Ah, thanks. Would you happen to have a recommendation for both air and liquid, lad?

manofchalk · Jul 10, 2014

Not really. The aforementioned NH-D15 is the best you can get on air (perhaps tied with the Phanteks PH-TC14PE) and on the CLC side all the 240mm rad units are pretty much the same.

You could go full out and get custom water, but that's a a fairly significant price increase (think $300 for a CPU loop thats easily capable of including a GPU later on) and necessitates a large case.

manofchalk :

An INCREASE of $300 or a total of $300? If it's the latter then I'll probably go with that, and immediately include the GPU water block. Casewise I was going to go with a fulltower anyway.

manofchalk · Jul 10, 2014

$300 for a CPU loop. Throwing a GPU in there, its going to be somewhere around $400-450 depending on the block.

manofchalk :

Awesome mate, thank you so much. Last thing: can you recommend specific parts, if not, brands? And the coolant, best non conducting coolant?

manofchalk · Jul 10, 2014

Nope

Your going into the world of water-cooling, as you can understand its a bit complex and does carry some small amount of risk. My advice, read the water-cooling sticky, put together a loop you think will work and post it for feedback. You need to know what your doing here, so I'm not going to give you a parts list like I would with a system build.

Also, there is no such thing as non-conducting coolant.
It may be non-conducting out of the bottle, but it certainly isnt once its spent a month or two in a loop. uS is a measure of electrical conductivity, it doesnt take long.
