Необходимо ли жидкостное охлаждение для высокой производительности процессора в течение продолжительных периодов времени?

In short, no

Liquid cooling is still mainly for bragging rights. Getting those extra MHz from hardware and pushing for extra benchmark points.

Will you need something aftermarket to cool your system? Absolutely.

Of course keeping temperatures as low as possible is always a thing we strive for, but you have to weigh up the costs and risks to the performance benefits.
Pumps, radiators, reservoirs, heat sinks, fans, tubing and coolant add large amounts to a build's cost.
Even All-in-one's are quite pricey (and can cause problems, boil-off, pump fail's etc).

Another downside with water cooling is that it is difficult to tell that anything has failed. They can operate near silently and leaks can go undetected until something blows up.
This is not to say they are less reliable than fan-cooled systems but at least you know if your loud fans have stopped working and there's very little chance of them taking anything else out with them if you are around monitoring.

Basically I would get a beefy heat-sink with at least a 120mm fan, something like a Noctua or Zalman (I am not affiliated) and then an intake and an exhaust to keep cool air moving. RAM cooling is rarely necessary but solutions are available from companies such as Corsair.

Get quality assured names with plenty of reviews. This PC sounds fairly mission critical so invest wisely to keep it running.

For reliability, you may want to look into passively cooling the CPU with an oversized heatsink and install extra large fans in the chassis.

The reason is having the CPU fan fail tends to cause a much longer downtime than replacing a chassis fan. If you run the chassis fan directly off the PSU instead of the mobo, you can even change them out without turning off your computer.

Larger fans also last longer because it doesn't need to spin as fast to push the same volume of air. It will also naturally run quieter for the same reason.

The major reason liquid cooling is so much more common is that it has gotten much simpler, cheaper, and more reliable. It is not because new builds require the liquid cooling. That said, there are some times when it's worth the additional set-up complexity.

It depends in part on the motherboard. If it is one advertised for overclocking/gaming et cetera, it may have been designed with the assumption that there would be a liquid cooler in play. I ran into this where there was a capacitor bank right by the CPU, while the CPU never got above 70C, the capacitor bank impeded air flow from the chassis fan and eventually cooked.

Also, liquid cooling is quieter, more efficient, and lets you pull the heat all the way out of the chassis instead of just out of the CPU. If the computer is going to be someplace where people regularly are (office, home, et cetera), then the noise reduction is nice; if it's under a desk, having the chassis stay cool is nice. Also, if you start with an all-in-one kit, and replace the hoses with longer ones, you can potentially mount the radiator outside, which can make the liquid cooler pay for itself in the summer. The cost on sale for an all-in-one kit is often similar to the cost of a chassis fan + better heat sink, so it mostly comes down to a tradeoff between extra maintenance and quieter cooling operation.

Honestly, as an owner of the same CPU in a similar system, I would say most definitely. Do not be fooled, the 5960X is a very fast and efficient CPU, but it's also deceptively hot because it's actually so much smaller than the 3930k I upgraded from and thus the heat is much more concentrated. And even the 3930k was very heat sensitive.

I RMA'd my 3930k due to heat damage while it was running on air and talked to Intel directly about it, so I will talk more about that than the 5930k I have now.

If you actually look at the specification of the CPU, which nobody ever seems to do these days, it's only rated for 66 degrees max (virtually the same as the 3930k). According to Intel, that's because the CPU is so far from the heat spreader and (CPU) case temp sensors that when the sensor reads 66, the cores are significantly higher in places. I RMA'd my 3930k due to heat-induced failure and it never did over 75C but it must have been a lot more because that managed to burn out TSC circuits in the chip and it's self reporting features refused to boot any OS.

That was on a Arctic Freezer i30 at stock clocks. It's actually damn near impossible to keep the 3930k under 62C (it's max is a little lower than the 5960X) under load without a very noisy system, and I'd actually alt-tab from gaming sometimes to let the CPU cool, so add two cores, make all of them smaller (so the heat is more densely packed) and your problems only increase, even with lower power draw.

I bought a closed loop water-cooler. I suggest you do the same. (H80 FYI) Never tried to overclock beforehand, but after I can run the 3930k @ 4.3 @ 63C under load, and low 50s stock under load. It's my only Closed loop, so I expect the same from others, but it's built very solid and I highly doubt it will ever leak. I would recommend not building your own for that very reason.

I used the same cooler on my 5930k, and it maxes 56C. I'm don't really see a point in oc atm so I haven't tried. My baby is still new lol. I will comment that you might wanna consider ECC RAM and a Xeon if you're doing something like Programming. I've ran into guys that had single bit errors while compiling that caused their software to be released with a bug that took them an incredibly long time to figure out and fix.

Yes.

I just put together a new Xeon E3-1276 v3 (Haswell) board (like the i7-4790 with more cache and ECC memory capability). With the supplied cooler, even with no case, it overheated (100 degrees Celsius! ) after one minute running Prime95 64-bit. (NOT overclocking, BTW)

Even a simple closed-loop liquid cooler essentially moves the bulky radiator outside and removes the size and weight restrictions for motherboard mointing and fitting inside a case with airflow.

I've never had a leak once a system is tested and comissioned, since I turned to water cooling in the Pentium Prescott era.

For mundane systems I use something like the Coolermaster big square radiator that sits on top of the CPU with a 140mm fan on the side. But for sustained performance cooling, you would also need (at least) case fans or ducting to go with that, and I don't know just how much it could handle without being very noisy and take a huge volume of air.

From the discussions in the comments, it appears that performant code can push it far beyond the thermal limits, so water cooling is necessary to make use of that performance capability.

To make it clear: this is not overclocking and is running the MB, memory, and CPU at stock specifications. Number crunching code can significanly exceed what the supplied stock cooler can handle.

Likewise, the turbo core feature is not applicable because (with the standard settings) it will not be engaged unless some of the cores are idle, and simply not boosting will not be considered an error if boosting would push it over the limit.

An after-market heat sink that maxes out the weight that can safely be supported by the motherboard could handle more heat if you give it enough air flow, but I can't say for certain what that is capable of with in-case use. My gut feeling is that if it doesn't make as much noise as a vacuum cleaner, it won't keep up.

Considerations: some similar processors have fewer cores or lower clock speed, and that would make a difference.

I also have a E3-1245v3 (3.4GHz instead of 3.6) running a file server and it has no problems whatsoever with a 5" square heat sink. The emphatic yes to liquid cooling is for High Performance Computing (CPU number crunching) usage.

Also, if testing the effectiveness with your actual use case, be careful not to under-do it. The software might get updated to use new instructions or be optimized for that architecture, and you would not be able to take advantage of the performance improvements, if that now pushed you 20W beyond your thermal limit.

Мысль 1

Мои два цента на жидкостном охлаждении состоят в том, что если вы хотите систему «установил и забыл», то используйте воздушный охладитель огромных размеров.

Даже если вы думаете, что будете очищать от пыли, часто учитывайте тот факт, что большинству жидкостных кулеров также необходим вентилятор, и их эффективность снижается вместе с накоплением пыли.

В большинстве случаев штатного кулера должно быть достаточно для охлаждения процессора, но, как правило,; тепло убивает.

Теоретически, запуск процессора при 40 ° C может дать срок службы 10 лет.

Запуск этого же процессора при температуре 60 ° C может обеспечить срок службы 6 лет.

Ни одна из оценок не установлена ​​в камне, но именно поэтому вы всегда должны стремиться к более низким временным температурам.

Учитывая ваш сценарий использования, возможно, стоит изучить создание системы, поддерживающей ECC RAM.
