Air cooler 5930k

GraySenshi · Jan 17, 2017

I'm using a x99 deluxe all ram slots are being used and the top gpu slot is used. what would be a good cooler for dead silence and oc.

Im sitting here asking myself why this is titled 'air cooler 5930k'. Air coolers are NOT suitable for cooling a CPU that you want to OC. They don't have the capacity to remove enough heat to let you achieve any decent stable overclocks. You need to look at getting a water cooler, this goes doubly as you will have limited space for a cooler.

Does the CPU get damage if it gets overheated and shuts down. The thing I don't like about the closed loop is it will eventually die on me where if you get a NH-D15/NH-D14 as long as it doesn't break the mb or can cool enough. Wasn't sure if it would work. I run my system almost 24/7

GraySenshi :

Firstly yes overheating causes a lot of damage!!

Secondly a custom loop (which i have alot of experience with) will generally last 3-4 years before the liquid should be replaced, in a closed loop itll last around 5 years at which point most people will be looking to upgrade their computer. It has less of a chace of failing then an air cooler as generally the pump is less likely to fail than a fan. Also every closed loop system will come with software that lets you monitor it, and will give you real time temps.

The big reason why you need a liquid cooler, is because even with the highest tier air cooler youll be sitting on around 70-80 degrees c, where as a liquid cooler should sit it closer to 40 degrees. Any over clocker will tell you this, DO NOT oc on air cooling as you will over heat you CPU.

Also please note if youre over clocking you have to burn in the cpu at your voltage you clock it to, to make sure its stable this means running it for 10+ hours at around 100% using software such as prime98 if you do this with an air cooler you will ruin the CPU.

At this point in time closed loop cooling is so reliable and at such a good price point you really should never be using an air cooler unless youre going for a ultra budget build.

I'm going to disagree with wehler53. A Noctua D15 performs just as well (or better) than any water cooler under $150 and does so with less noise. I highly recommend it, or one of Cryorig's top-end coolers such as the R1.

You might take a look at this review: http://www.relaxedtech.com/reviews/noctua/nh-d15-versus-closed-loop-liquid-coolers/1

The 5 liquid coolers on the list are not 30-40c cooler as wehler53 suggests, and for every 3dba rise in sound pressure, noise is doubled, so the Kraken (just as an example) is more than 30x louder than the D15 with approximately the same cooling.

Also, Intel CPUs protect themselves from overheating. You could safely remove the heatsink from your CPU entirely while it was running and it would not suffer any damage. I've seen cases where heatsinks have literally fallen off and the person didn't know about it for months, other than that their PC got very slow as the chip bounced off of thermal limits and slowed itself down.

That said, while there are no air coolers that can compete with a high-end custom loop in terms of raw heat dissipation, watercooling pumps are always noisy and not suitable for "dead silence". A high-end tower heatsink is more than adequate for overclocking and probably the best choice.

I have to disagree im running a complete customer cooling loop with a pump that pumps around 1000L/min and it makes less noise than my corsair quiet series fans. My roommate had me build a computer for him and i used a corsair 100i, again using corsair quiet series fans you cannot hear the pump even in a quiet room. In fact most computer builders will recommend a water loop if you want a silent system.

Whilst ill agree for certain CPUs air colling does a good enough job to not warrant air cooling i cant stress enough that the pictures youve shared for the 4790K is not a good point of reference we are talking about a 88w (4790k) vs a 140w (5930K). This means more electricity is being sent through the 5930k at any point in time, which means when its over clocked it will get alot hotter which is where the aircooler will hit its ceiling well before the water cooler will. A much fairer comparison would be the 5820k vs the 5930k, and as it happens im using the 5820k in my current build. Under full load on my current stable OC it runs at around 65c with a custom loop, with a 100i it ran 75c and with a deepcool assassin which is very simialr to the Noctua D15 ran at very close to 90c and a few time safety shut down.

Ultimately its up to you, during idle use a water cooling loop is generally silent as the pump has no load and the fans spin very slowly, and only speeds up under stress. you may want to check your info on the noise gap, youre looking at a max of 40dB under full load with a water cooling loop vs around a bit under 30dB with a top of the line air cooler.

Keep in mind those air coolers make creating a possitive upward air flow in your case very difficult and those fans are quite an eyesore. The choice is yours, youll always achieve better over clocks with liquid cooling, but if you feel better using an air cooler by all means do it. This is your build and i can only give recommendations based on my experience.

You'll be able to OC with both, itll just depend on how much over clocking you want to do.

A fair point. I ran custom loops for a while but I've moved more toward low power computing, where water is more of a liability and has little practical value. With my current mild overclock + large undervolt, the CPU in my signature draws little more than 40w.

With cooling, surface area is the name of the game, and less surface means more airflow is needed for the same results. AiO coolers typically have no more surface area than a good tower heatsink, and come with disappointing pumps. A custom loop can indeed perform significantly better when paired with a very power hungry CPU, but they're also not remotely in the same price bracket. A good custom loop can easily set you back $3-400, which in my opinion is a lot of money to spend chasing 5-15% more CPU performance. We all have different priorities though.

True "dead silence" would be strapping a Scythe Ninja or Prolimatech Megahalems to the CPU and then not using any fans. Passive cooling is always dead silent. How practical that is, well it probably isn't. Definitely not for 5930k. Everything else is going to make noise. To me, it's more of "what kind of noise" than "how much noise", since my first gen H100i was far from silent, even with Gentle Typhoons, but neither are the Hyper T4 and TX3 I own.

I don't know what OP has in mind for longevity, but an air cooler tower, unless damaged by blunt trauma, will continue to function forever, provided that thermal paste is regularly replaced as it becomes dry and crusty (every couple years?), it gets regularly dusted off (every few months?), and has dying fans replaced. AIO's on the other hand, generally live as long as the pumps do. My personal experience with them is a 22 month lifespan for two AIO's, an H100i and an H110. Some claim 3-5 years. Others arrive DOA. My 5 year old TX3 is still functioning as well as it did on day 1.

Basically, AIO's cool better but live shorter, air coolers live longer but take more space to do its cooling. There are trade-offs for both, neither are going to cool to sub-ambient temperatures. If you live in a place where it's 27C in the summer and you have no AC, temps will suck either way.

Personally, I'd pick air cooling, at the cost of ease of install, for the ease of mind and the set-and-forget mindset you can adopt once it is installed.

Ecky :

Agreed, it all depends on your build and CPU and your needs. Realistically with these high tier CPUs there isnt all that much need for over clocking unless youre ding things that are very CPU reliant such as rendering. Something worth keeping in mind for the OP is what you mentioned about surface area which is where a water loop always comes out on top. I really just comes down to what the OP wants if $50 - $75 more isnt important you can have basically the pick of the closed loops avaliable

wehler53 · Jan 17, 2017

amtseung :

You raise some very interesting points. The very top of the line fans are rated for 100,000 - 150,000 hours (around 8 years) although thats in optimal conditions... where as a pump in most closed loops will be rated 50,000 (5 years) with a 99.9% no failure rate. But with anything thats always depends ive had 4 fans fail on me so far and my pump is still running beautifully 18 months into my builds life. The point on dust is where ill state the possitive upward airflow, a positive airflow means youll have very little dust in the system, however heatsinks tend to be dust collectors particuarly ones that big. On average a user of a system like the OPs would look likely at replacing the system around every 4 years id assume so either option is definetly viable when it comes to life span.

I do however agree that air cooling does have a sense of security about it, i find mysef sometimes concerned about my custom loop. However most loops come with software thatll tell you as soon as theres a failure, so thats nice.

Also if you use good quality thermal paste you shouldnt need to replace it any more often than every 3-4 years.

There is one Air Cooler that Comes to mind that can be found on Newegg for $85, The Be Quiet! Dark Rock PRO 3. It is Be Quiet!'s most high end air cooler. She is a behemoth in size, But she is rated for CPU's with a TDP of up to 250 (god forbid such a CPU existed)
