The O11 Dynamic was a case we liked enough to keep around for housing one of our work PCs. The layout is nonstandard, from the side intake vents to the placement of the PSU and storage, but it works. It may be the only case we’ve ever tested with a completely sealed-off glass front panel that still managed to perform actually well in testing. The O11 Air variant impressed us somewhat less, but improved substantially when the dust filtration was removed. Now, in 2019, Lian Li is introducing the O11 XL, a larger version of the original case, still bearing the Der8auer badge for his initial work on the O11 Dynamic.
Like the Dynamic, this case is meant to be used for water cooling builds, but our standardized test bench is used for air testing. This is still useful to determine the performance capabilities of the case, as it’ll all scale when comparing one case to the next, but note that water cooling can obviously brute-force its way past a lot of thermal issues. Still, the O11 Dynamic made an actually good air-cooled case thanks to the bottom intake and side intake options, so even though it looks best as an aquarium, it didn’t have to be one.
The Coolman Threebody is a case we bought in the Shenzhen SEG E-Market in China and had sent back to us, along with a couple other items that might show up in future content. This is less of a review and more of a look at some cool features in a weird case, since most of our audience can’t wander down to Shenzhen and pick one up. Maybe Western-market case manufacturers can take some cues from the Threebody’s design. Asking price at the market was $66 US, and we paid $60 for it.
The most optimistic feature of the Threebody is the big yellow warning sticker that says TEMPERED GLASS: Please handle with care. Both translucent side panels are very definitely plastic and not glass, as curved glass panels are a luxury even for major manufacturers like Cooler Master. It’s not a lie since the small pane on top of the case is glass, but this is also the smallest and most hidden of the three clear panels, so maybe they should have gone for plastic there as well.
The NZXT H510 Elite is NZXT’s premium spin on the H500 -- no, not the Cooler Master H500, not the H500P, not the H500M, and definitely not the 500D or A500, but the NZXT H500. NZXT’s H500 is a case that wasn’t top-of-the-line in thermal performance but that we liked anyway for its good build quality at a very reasonable $70 price point and reasonable thermals. NZXT must be proud of the new H510 Elite, because they sent us two identical ones. The H510 Elite is being introduced alongside the H510, which is the same as the H500, but with a USB type-C port replacing one of the type-A ports on the front pane. It’s also similar to the H510i, which includes an NZXT “Smart Device.” The Elite has a tempered glass front panel, LEDs, and two RGB fans as front intake (3 fans total) as well as the USB-C port and Smart Device. We’ve expressed our opinion on these devices before, intended to automatically run fans at the optimal cool-and-quiet speed, but these new devices are version 2. We plan to do some more testing with them soon, but for the purposes of this review we bypassed the smart device completely and controlled fan speed via the motherboard as usual.
For the purposes of this review, we’re going to pretend no other cases named H500 exist. If we say H500, we mean the NZXT H500. Note also that we had written and filmed this about 3 weeks prior to publishing, but notified NZXT in between writing and now that we had found issues with thermals in the case. As such, NZXT has modified its listing and now offers an extra 120mm exhaust fan (free for those who already bought the case) with the enclosure. We didn’t rewrite our entire review around this change, but added in two charts to cover it where necessary.
This is a quick and straightforward piece inspired by a Reddit post from about a week ago. The reddit post was itself a response to a video where a YouTuber claimed to be lowering temperatures and boosting performance on Ryzen 3000 CPUs by lowering the vcore value in BIOS; we never did catch the video, as it has since been retracted and followed-up by the creator and community with new information. Even though the original content was too good to be true, it was still based on a completely valid idea -- lowering voltage, 50% of the equation for power -- will theoretically reduce thermals and power load. The content ended up indirectly demonstrating some unique AMD Ryzen 3000 behaviors that we thought worth testing for ourselves. In this video, we’ll demonstrate how to know when undervolting is working versus not working, talk about the gains or losses, and get some hard numbers for the Master and Godlike motherboards.
With the launch of the Ryzen 3000 series processors, we’ve noticed a distinct confusion among readers and viewers when it comes to the phrases “Precision Boost 2,” “XFR,” “Precision Boost Overdrive,” which is different from Precision Boost, and “AutoOC.” There is also a lot of confusion about what’s considered stock, what PBO even does or if it works at all, and how thermals impact frequency of Ryzen CPUs. Today, we’re demystifying these names and demonstrating the basic behaviors of each solution as tested on two motherboards.
Precision Boost Overdrive is a technology new to Ryzen desktop processors, having first been introduced in Threadripper chips; technically, Ryzen 3000 uses Precision Boost 2. PBO is explicitly different from Precision Boost and Precision Boost 2, which is where a lot of people get confused. “Precision Boost” is not an abbreviation for “Precision Boost Overdrive,” it’s actually a different thing: Precision Boost is like XFR, AMD’s Extended Frequency Range boosting table for boosting a limited number of cores when possible. XFR was introduced with the first Ryzen series CPUs. Precision Boost takes into account three numbers in deciding how many cores can boost and when, and those numbers are PPT, TDC, and EDC, as well as temperature and the chip’s max boost clock. Precision Boost is enabled on a stock CPU, Precision Boost Overdrive is not. What PBO does not ever do is boost the frequency beyond the advertised CPU clocks, which is a major point that people have confused. We’ll quote directly from AMD’s review documentation so that there is no room for confusion:
