The tested water blocks include:

  • Alphacool NexXxos XP3 Light V.2
  • Phobya UC-2 LT
  • Raijintek CWB-C1
  • Heatkiller IV Pro Pure Copper
  • XSPC Raystorm Pro

The review offers an thorough look at the design of each water block, as well as an interesting look at the effects of flow-rate on performance:

"The test has been shown that with increasing flow rate decreases the temperature difference of the water before and after heat sinks. However, the question arises whether a higher flow also has a positive effect on the cooling performance itself. A negative effect of increasing flow as well: Most pumps are unthrottled very loud to work, so that a reduced pump capacity is useful for a silent water cooling."

GamersNexus Disassembles an EVGA Hybrid Liquid Cooler

Subject: Cases and Cooling | August 1, 2016 - 09:38 PM |
Tagged: evga, asetek, liquid cooler, closed-loop

Well this is interesting. GamersNexus has about a twenty minute video (and a couple-page editorial) where they disassemble an Asetek / EVGA liquid cooler for GPUs. He spends the first half of the video with a discussion of previous videos, an overview of the industry and its split between vendors and manufacturers, and an explanation of various components including the difference between CPU and GPU plates. The second half of the video disassembles the cooler, talking about it as he goes.

The disassembly begins at ~9 minutes.

The availability of closed-loop coolers introduced me to water cooling. While I could be very careful to do everything right, I just don't trust myself to assemble a liquid-filled (non-conducting or otherwise) component that close to electronics. Part of that could be attributed to my childhood, where a dead PC meant no computer for x number of weeks, or months, because we could barely afford one at all. An assembled (and warrantied) cooler, though, while still intimidating when the tubes get even slightly torqued, is clearly designed to go in hassle-free and remain working without maintenance. That's a good part of why, while it's pretty obvious what is inside these units, seeing it first-hand is fascinating (at least for me).

Seasonic Flagship PRIME 750W, when they upgrade they mean business

Subject: Cases and Cooling | July 25, 2016 - 04:53 PM |
Tagged: modular psu, Seasonic PRIME, 750w

It has been about a year since Seasonic released a brand new PSU as they do not tend to flood the market with incremental upgrades to their PSU families.  While this may hurt their business a little as newer users do not see reviews or advertisements frequently, long term enthusiasts take note when a new PSU arrives.  This fully modular PSU offers a single 12V rail capable of delivering 744W @ 62A and offers six 6+2 PCIe power cables, it even still has a floppy connector for those desperate times when you need to pull one out.  [H]ard|OCP strapped the PSU to their torture bench and this Seasonic unit came out with a Gold medal.  Check out the full review here.

"Seasonic has never been big on marketing-speak. Outside of its impressive specifications, and a list of features, this is all it has to say. "The creation of the PRIME Series is a renewed testimony of Seasonic's determination to push the limits of power supply design in every aspect." Let's see if that is true, or the shortest sales pitch ever."

Video Perspective: EVGA DG-87 Case Preview

Subject: Cases and Cooling | July 22, 2016 - 05:50 PM |
Tagged: video, huge, evga, dg-87, dg-8, case

EVGA started showing off designs for a unique, and enormous, case in 2015. It has since been rebranded and has undergone some minor work at the plastic surgeon to emerge as the EVGA DG-8 series of chassis. EVGA sent me the flagship model, the DG-87, that features an integrated fan controller to operate intake and exhaust airflow individually. EVGA took some interesting chances with this design: it's bigger than just about anything we have ever used, it rotates the case orientation by 90 degrees so that what was normally your side panel window is now facing you and it routes all of your cables and connections through a side section and out the back side of the case. 

If you haven't seen it before, this video is worth a watch. Expect a full review sometime in August!

SFX form factor cases and power supplies continue grow in popularity and in market share. As one of the original manufacturers of SFX power supplies, Silverstone Technology Co. is meeting demand with new products; continuing to raise the bar in the SFX power supply arena with the introduction of their new SX700-LPT unit.

SX700-LPT
(SX=SFX Form Factor, 700=700W, L=Lengthened, PT=Platinum certified)

SilverStone has a long-standing reputation for providing a full line of high quality enclosures, power supplies, cooling components, and accessories for PC enthusiasts. With a continued focus on smaller physical size and support for small form-factor enthusiasts, SilverStone added the new SX700-LPT to their SFX form factor series. There are now seven power supplies in the SFX Series, ranging in output capacity from 300W to 700W. The SX700-LPT is the second SFX unit to feature a lengthened chassis. The SX700-LPT enclosure is 30mm (1.2”) longer than a standard SFX chassis, which allows using a quieter 120mm cooling fan rather than the typical 80mm fan used in most SFX power supplies.

The new SX700-LPT power supply was designed for small form factor cases but it can also be used in place of a standard ATX power supply (in small cases) with an optional mounting bracket. In addition to its small size, the SX700-LPT features high efficiency (80 Plus Platinum certified), all modular flat ribbon-style cables, and provides up to 700W of continuous DC output (750W peak). The SX700-LPT also operates in semi-fanless mode and incorporates a very quiet 120mm cooling fan.

Introduction: Rethinking the Stock Cooler

AMD's Wraith cooler was introduced at CES this January, and has been available with select processors from AMD for a few months. We've now had a chance to put one of these impressive-looking CPU coolers through its paces on the test bench to see how much it improves on the previous model, and see if aftermarket cooling is necessary with AMD's flagship parts anymore.

DSC_0411.jpg

While a switch in the bundled stock cooler might not seem very compelling, the fact that AMD has put effort into improving this aspect of their retail CPU offering is notable. AMD processors already present a great value relative to Intel's offerings for gaming and desktop productivity, but the stock coolers have to this point warranted a replacement.

Intel went the other direction with the current generation of enthusiast processors, as CPUs such as my Core i5-6600k no longer ship with a cooler of any kind. If AMD has upgraded the stock CPU cooler to the point that it now cools efficiently without significant noise, this will save buyers a little more cash when planning an upgrade, which is always a good thing.

A quick search for "Wraith" on Amazon yields retail-box products like the A10-7890K APU, and the FX-8370 CPU; options which have generally required an aftermarket cooler for the highest performance. In this review we’ll take a close look at the results with the previous cooler and the Wraith, and throw in results from the most popular aftermarket cooler of them all; the Cooler Master Hyper 212 EVO.

Scythe's Fuma cooler, stocky and quiet but not ready for overclocking contests

Subject: Cases and Cooling | July 20, 2016 - 04:12 PM |
Tagged: scythe, fuma, heatsink

Scythe's Fuma heatsink is a fair size at 137x149x130mm with a weight of 920g, including the two 120mm fans, though shorter than many on the market.  That stock design could cause some problems if your RAM has impressively sized heatsinks but for most modules you should not have any issues and it does not impinge on your first PCIe slot.  In the tests Modders-Inc performed reasonably well when cooling an i7-4770k at stock speeds, unfortunately an overclock of 4.4GHz did see the cooler struggle and the CPU frequency was throttled back almost immediately.  For lesser loads the low RPM fans will be able to keep your temperatures reasonable and do so without creating much noise.  If you have a midranged CPU and want a quiet cooler in the $55 range, drop by to check out the full review.

"Heatsink designs are driven by the fundamental principle that a larger surface area equates to better heat dissipation than a smaller area. Factoring in componential consent, modern aftermarket CPU tower heatsinks had to get creative to compensate and dial-in the efficiency needed, hence the rise of dual-tower cooler designs"

Introduction and First Impressions

A newcomer in the PC enclosure space, RIOTORO has a lineup of unique-looking products to offer in a market flooded with options at every price-point. With this full-tower PRISM CR1280 enclosure the company says that they are providing not just a home for your components, but the world’s 1st fully RGB case with unparalleled personalization options”.

DSC_0353.jpg

Clearly, RGB lighting has been one of the biggest trends in PC hardware for the past year or so, and if you are so inclined the PRISM CR1280 promises fully customizable color with lighted accents on the front of the case, and included RGB intake fans.

DSC_0370.jpg

Beyond the RGB lighting, however, the PRISM CR1280 has a rather unusual industrial design. There is angular black plastic over a steel body, and a large edge-to-edge side panel window (not to mention those bare aluminum feet). It looks like a premium enclosure, and it’s certainly priced like one with an MSRP of $169.99 (selling for $149 currently). Is it worth it? Read on to find out!

Lee reviewed the Corsair SF600 back in June but you might not have been shopping for a new PSU, especially a SFF one.  Take another look at the performance of this PSU over at [H]ard|OCP, which should be enough to power an RX480 or GTX1070 based system if you are eyeing a new system build.  They agreed with our results, giving out a Gold Award but also mentioning the SilverStone SX600-G, an older PSU with a smaller price tag and a feature or two that might interest you more than Corsair's new PSU.

"Corsair has gotten into making computers smaller lately with its Bulldog 4K Living Room Gaming System, and now it is going to share its SF600 power supply that follows the SFX standard form factor, which is tiny for a 600 watt PSU. Given its diminutive stature, has Corsair packed it to the gills with good power?"
