Hardline Liquid-Cooling a PC

A PC Cooler than the Other Side of the Pillow?
Why choose a hardline liquid-cooled computer? Well because it’s the coolest — seriously. No, literally.It’s the top-of-the-line customization/cooling strategy you can implement to get the maximum output from your high performance gaming computer. Just like a car, all that digital horsepower needs an outlet, like an exhaust. Where do electrons and heat go? What prevents your PC from bursting into flames?
Featured in the brand new AVADirect Avalanche Gaming Computer, PETG hardline liquid-cooling tubing takes liquid-cooling a PC to the next level. It’s like having a digital sports car. You have the ability to get the most out of your machine by optimizing the parts and rounding it off with the best performance based cooling. Think of PETG tubing like the best cold air intake on a car.
Before we cover the reasons why PETG tubing is a massive step above the rest: let’s review the science behind what PETG actually is. PETG (Polyethylene terephthalate glycol-modified) pipes are tube-shaped polymers produced by chemically-combining carbon molecules and then either extruding or casting the resin to take on the physical attributes of the tubing.
Another popoular alternative is acrylic tubing. Acrylic polymer compounds were crafted in the late 70’s to replace glass in some situations combining the durability and functionality of plastic pipes.

But why would you want rigid tubing in a custom PC? Here’s a few key reasons
  1. First, as with anything customized, is just raw & pure aesthetics. Visual supremacy. Are you someone that enjoys tight, crisp, visually enticing straight lines? This is an attractive feature for any enthusiast that requires a quality look and feel when configuring a new gaming pc….PETG is most likely the tubing choice for you. Due to the rigidity of PETG, it allows the PC builder to give you much straighter lines than any flexible tubing ever could give you – conform the tube loop into any desirable shape and allow the liquid to take any route you need it to (which is great if you want to customize a really intricate loop).
  2. Next, is the lack of plasticizer. If you’ve ever seen a cooling loop which has discolored tubing or a gunk build up, chances are it’s probably that plasticizer (which is used to make flexible plastic tubing softer). PETG tubing has none of this, and so will not discolor, cloud up, or cause your loop to clog from coolant discharge.
  3. The final key benefit is durability. Industry experts can attest, once you have configured the right loop, you will find that these tubes can and will last a long, long time. They take heat from your PC more effectively, and ensure that your hardware is running at ridiculously low temperatures.
Configuring custom PETG tubing for a high powered PC can be tricky without the technical knowhow and experience. That’s where boutique custom computer builders come in.  Here at AVADirect, we have prototyped and tested a few different configurations for the optimal cooling performance… We designed the Avalanche. The AVADirect Team voices and guarantees this system will run in the top percentile of any benchmark, overclocking, or game test.
Recently, the Avalanche was reviewed by CNET – see what they have to say about hardline liquid-cooling and positive effects it has on the configuration.
Performance-wise, the Avalanche backs up its impressive benchmarking scores with real world results […] I dare you to find a game that the Avalanche can’t run with all settings maxed out at 1440p. It’s just that powerful. I hooked the machine up to an ASUS Swift ROG G-Sync monitor (1440p) and a few 4K monitors for comparison. The Avalanche barely skipped a step making the jump to 4K […] the final product is not only a liquid-cooled machine that outperforms every similar rig we’ve tested, it’s also a work of art. ”  -Jeff Bakalar, Senior Editor, Senior Editor / Reviews – CNET.com

Choosing a CPU: Intel vs AMD

intel vs amd
It is not always easy to make choices and compromise when buying gadgets. Deciding which CPU to choose could be especially challenging when it comes when buying a new PC, whether it is a ready-made one or a custom configuration. Although the choices are limited – there are only two major CPU manufacturers for consumer PCs: Intel and AMD – it’s not an easy decision to make. So, let us see “who is who” nowadays on the CPU market and help you to make it a right decision.
First of all, it would be worthwhile to identify which tasks the future PC will be dedicated to performing the most. For example, if the computer will be used in a narrow, specific field like scientific research or massive data processing, or, if it will be an extreme gaming station or home theatre PC. Of course, you should not only consider the CPU, but other components, too, since overall performance of the system depends on all key components. For example, a last generation, top of the line video card and single core CPU that was launched, say, 5-6 years ago wouldn’t be a great combination for a good gaming, since the CPU will be slowing down the whole system due its weaker performance in comparison with video card. Don’t get it wrong – they would be still compatible and the PC will be working fine in general, but the performance in games will be quite questionable or even disappointing.

Value

By looking at the line-ups of both Intel and AMD, we will find out that AMD chips are a bit less expensive. However, that doesn’t make AMD chips a better value due to lower computing performance per dollar. Here it is important to understand how much money you are ready to invest into CPU by identifying the circle of tasks the future PC will be doing.
If budget is limited, but you are still planning to have an acceptable performance in gaming, for instance, AMD on-board graphics solutions have better performance than Intel for a lower price. For example, AMD’s Quad-core A10-7870K 3.9GHz is currently priced for around $140 and similar performance Intel Core i5 4440 3.1GHz is $180. Of course, AMD here is not a gaming powerhouse, but it will exceed the performance Intel HD Graphics solution, so you might be better off with AMD if you need to play games with medium details and 1080p resolution on a budget.
However, if budget is not a question here, Intel definitely will be preferable choice, since their chips still having superior computing performance per dollar. A piece of advice here – if you planning to buy a brand new processor on the day it is launched, you might end up paying considerably more, rather than you wait a couple of months, because usually prices drop dramatically after introduction of the new chips.

Overclocking

overclocking amd vs intelIn the low-end segment, overclockers usually prefer AMD processors to Intel, since AMD supports this CPU tweaking feature in a more consistent way. The whole AMD A-series and six chips that go under $100 with an unlocked multiplier can be easily overclocked from 3.2GHz to 4.5GHz, whether Intel offers only one budget CPU that can be overclocked 4.3GHz – Pentium G3258 at around $60.
In mid-range segment, AMD also offers several chips with overclocking features, while Intel doesn’t really. However, if we would talk about high-end segment of Intel’s processors, there are several that support overclocking (and some even with eight physical cores) and AMD here would be no match – these CPUs are much faster at stock clocks than anything AMD can offer so far, not to mention overclocking. You just can’t buy anything as quick as these for home use.
All in all, whether a wide overclocking support of AMD’s chips make them a better choice in a long run might be arguable. It would very much depend on both the general workload of the system and how much effort you are willing to put into overclocking.

Gaming

As its already mentioned, some AMD chips outruns Intel HD graphics in a budget gaming segment with their integrated Radeon graphic solutions – AMD has been heavily investing in graphics technologies (especially for laptops) since they bought ATI back in 2006. Although it would be worth to mention that the latest Intel Iris Pro technology implemented in the last generation of Core processors, is a big improvement over the previous HD Graphics systems.
However, when it comes to the question of serious gaming – integrated graphics systems would not be a preferable solution over dedicated graphic card. And here Intel processors may be a better choice due their impressive performance alongside the high-end graphics cards. AMD chips just are not that quick as Intel, which would have a significant slowdown of the system. Of course, by choosing Intel processors you’d have to consider a serious investment, but then again if you are serious about high-end gaming, that would be obvious and the only choice.

Power consumption and heating

AMD is managing to produce CPUs that are competitive to Intel ones, the drawback of their efforts appear to be a higher power consumption of their chips. As a comparison we might take the abovementioned Intel Pentium G3258 with TPD (Thermal Design Power) of 53W against similarly prices AMD A6-7400K with 65 watts TPD. Not to mention that according to benchmarking Intel chip is faster by most performance indicators and in some areas by a significant margin. Which means Intel would run faster while using less power. Hence, less heating and no need for more powerful and bulky cooling solutions for desktop systems. For example, Intel’s newest Core i7 5775C processor even when overclocked up to 4.2GHz is running under 60 degrees on the stress tests, which once again confirms that Intel is doing a better job than AMD at keeping their CPUs cool.

Custom PCs

If you’re planning to build up your own custom PC the situation here would be pretty much the same – AMD would win on the price for budget solution, but for serious performance demands we would rather recommend to go with Intel. And don’t forget the bottlenecks of AMD chips – power consumption and heat radiation. So if you still want to stick with AMD, you’d have to seriously think about proper and sufficient cooling. It doesn’t mean that Intel based systems are less demanding in this regard – proper and efficient cooling never hurts. It just mean that for Intel there’s less effort is required.
Another factor of consideration would be variety of the motherboards – Intel has a wider choice of boards (hence, more possibilities while estimating the budget) for any Intel’s CPU socket design in comparison to AMD.

And the winner is?

As a mainstream manufacturers of CPUs AMD and Intel have been in competition for decades now. There were ups and downs for both at different times. But as we can see today, Intel processors are slowly outweighing AMD ones by several factors, especially if you have a high budget – Intel chips here are faster, far more power efficient, which directly affects heat and noise producing into a lower rates. It could be especially critical, when you’re looking for a laptop – less power consumption will greatly improve battery life.
Nevertheless, there is no categorical and short answer who is the best – it depends on what you’re planning to do and what you’re willing to spend. Yes, Intel is generally superior, but AMD will make sense in certain scenarios as well. It’s all about putting up pros against cons and realizing what are you actually want to achieve. And if at the end of the day you’d still won’t be able to make up your mind – just go for Intel’s solutions. Most probably, it would be a win-win situation for you.
