Hardware news headlines with AMD's delay of the 3950X and the 7nm shortage that TSMC is experiencing. The shortage, it seems, is one of those "good problems" to have -- TSMC's 7nm process is so popular that it's struggling to keep up with demand, and so the fab is working to increase wafer output. Separately, news talks issues with iCUE software causing impact to FPS, somewhat unsurprisingly, in coincidental timing with the 465X iCUE launch.

We never reviewed the Corsair 460X, but now we are reviewing the Corsair iCUE 465X. It's good that we never reviewed the first case, because we’re thoroughly tired of trying to find new things to say about case revisions when we’ve just gotten through looking at the prior one. The 465X is a familiar design with a full-length PSU shroud and tempered glass side and front panels, but with open-air gaps on either side that so many case manufacturers seem afraid to commit to. Corsair's 465X is priced similarly to the NZXT H700 non-i, Cooler Master H500P Mesh, and Lian Li O11 Dynamic after fan purchases. Pricing is supposed to be in the $150-$160 range, with some impact assuredly from tariffs and the rest from the RGB LEDs, three fans, and cut-down Node internally.
Asetek has a stranglehold on most of the closed-loop liquid cooler market for PC hardware, easily holding majority placement in all CLCs sold in the US. CoolIT has long been a contender of Asetek’s, with the two having battled legally over Asetek’s patents on pump-in-block design, and has also been one of Corsair’s two liquid cooling partners. Both Asetek and CoolIT make the Corsair liquid coolers, though the latter fell out of popularity for a number of years. Finally, with the Platinum line, Corsair is working with CoolIT in a mainstream product. The H115i Platinum uses a new pump and block design, and that’s something we’ll show off thoroughly in our upcoming liquid cooler internals comparison video. For today, we’re focusing on reviewing the $160 H115i Platinum for thermals, acoustics, and overall value at the price point.
Asetek has previously received settlements in legal disputes against CoolIT, the other supplier of Corsair’s closed-loop liquid coolers, and has also won legal battles against Cooler Master for its Seidon series. Asetek, it seems, has a patent on the pump-in-block design approach, and has had judges rule in its favor. This has led to an exodus of non-Asetek coolers in the US market, with companies like Swiftech and Be Quiet! pulling their similarly-made (but non-Asetek) coolers out of the US market. We’re left with a few braver souls, like those using Apaltek-made designs, and some companies that have worked around the patents. DeepCool would be an example, which uses a three-chamber, very complicated approach to its pump manufacturing.
Hardware news this week focuses once again on process improvement and Ryzen 3000 discussion, although there's also a CLC recall that affects about 1% of Corsair Platinum owners (due to a leak). We also talk about the Epic Games' response to conspiracies surrounding Tencent and 'spyware.'

The Corsair Crystal 680X is the newer, larger sibling to the 280X, a micro-ATX case that we reviewed back in June. The similarity in appearance is obvious, but Corsair has used the past year to make many changes, and the result is something more than just a scaled-up 280X and perhaps closer to a Lian Li O11 Dynamic.
First is the door, which is a step up from the old version. Instead of four thumbscrews, the panel is set on hinges and held shut with a magnet. This is a better-looking and better-functioning option. It’d be nice to have a way to lock the door in place even more securely during transportation, but that’s a minor issue and systems of this size rarely move.
Removing the front panel is a more elaborate process than usual, but it’s also unnecessary. The filter and fans are both mounted on a removable tray, and everything else is easily accessible through the side of the case. Fan trays (or radiator brackets, or whatever you want to call them) are always an improvement. If for some reason the panel does need to be removed, it involves removing three screws from inside the case, popping the plastic section off, and removing a further four screws from outside. The plastic half is held on by metal clips that function the same way as the plastic clips in the 280X, but are easier to release. Despite appearances, the glass pane is still not intended to be slid out, although it could be freed from its frame by removing many more screws.
Corsair’s H100i Pro is the third Corsair product to use Asetek’s 6th Generation pump solution. Asetek didn’t push performance in significant ways with 6th Gen, but instead focused on endurance improvement and reducing hotspots that encourage permeation of the tubes. This time, just to keep things sort of interesting, we’ll talk about how pump speed impacts the performance of this particular cooler – a topic we’ve explored with Gen5 coolers in the past.
We originally detailed Gen6 in this H150i Pro review, if you’re a bit behind. On the whole, Asetek’s sixth generation pump isn’t all that different from its Gen5 pumps. Performance is marginally worse, if anything, as almost all changes were focused on slimming down the CPU block and improving endurance. Asetek looked at key hotspots in its Gen5 pumps and rerouted flow to reduce strain and failure potential. Liquid should still remain below 60C at all times, but Gen6 will now better enable this than Gen5. Don’t expect better performance, though. Despite improving the impeller quality significantly, overall performance remains unchanged at best, if not slightly worse.
Frequency is the most advertised spec of RAM. As anyone who’s dug a little deeper knows, memory performance depends on timings as well--and not just the primary ones. We found this out the hard way while doing comparative testing for an article on extremely high frequency memory which refused to stabilize. We shelved that article indefinitely, but due to reader interest (thanks, John), we decided to explore memory subtimings in greater depth.
This content hopes to define memory timings and demystify the primary timings, including CAS (CL), tRAS, tRP, tRAS, and tRCD. As we define primary memory timings, we’ll also demonstrate how some memory ratios work (and how they sometimes can operate out of ratio), and how much tertiary and secondary timings (like tRFC) can impact performance. Our goal is to revisit this topic with a secondary and tertiary timings deep-dive, similar to this one.
We got information and advice from several memory and motherboard manufacturers in the course of our research, and we were warned multiple times about the difficulty of tackling this subject. On the one hand, it’s easy to get lost in minutiae, and on the other it’s easy to summarize things incorrectly. As ASUS told us, “you need to take your time on this one.” This is a general introduction, to be followed by another article with more detail on secondary and tertiary timings.
The review embargo on Corsair’s new Crystal 280X micro-ATX case lifted during Computex, possibly the busiest week of the year--but since we’ve just started testing small form factor cases, we chose to push back the review another week or two.
The 280X is fairly large to call itself small form factor, and that can be an unfair advantage when comparing performance against truly small mini-ITX cases like the SG13. One justification is that (unlike the Cryorig Taku), the 280X uses its extra room to supports full-size components except for the motherboard, which must be either micro ATX or mini ITX.
Corsair’s H115i Pro launched alongside the H150i Pro, the first two closed-loop liquid coolers to use the Asetek 6th-Gen pump. As we said in the H150i Pro review, Asetek didn’t do Corsair any favors, here – the new pump isn’t much different from the old one, and primarily focuses on RGB implementations akin to NZXT’s custom work on the XX2 series. Regardless, Corsair has taken this and used it as an opportunity to bundle their new CLCs with silence-focused fans, the ML120 Pro fans.
As shown in our tear-down of the 6th Gen Asetek pump, where we took apart the H150i Pro, the primary changes of the pump are endurance-focused, not performance-focused. Asetek is ultimately the supplier, here, and that means Corsair’s main contributions are restricted to fan choice; that said, Corsair did dictate large parts of the 6th Generation design. Asetek now includes an RGB LED kit for manufacturers, and also includes the PCB for programmable LEDs (something that NZXT previously went through great effort to customize on the 5th generation). The 6th Gen Corsair coldplate is also marginally smaller than the fifth generation, but other than that, it’s all endurance-driven. Asetek has changed its impeller to a metal option, similar to the old Dynatron impellers in the Antec 1250 Kuhler series. Asetek has also reportedly “optimized” their liquid paths to reduce hotspots that caused higher permeation than desired in older generations.
In terms of performance, though, our extensive testing results (and our contacts) all indicate that the 6th Generation is not an improvement in cooling. At best, they’re the same. And that’s at best.
The Corsair 270R won our Editor’s Choice award when we reviewed it back in 2016. The 570X was the main event in that article, but we also praised the 270R as a decent case with a launch price in the $60-$70 range--and we’ve continued to mention it favorably, since it’s gone on sale for as low as $50. Now the 275R is here, Corsair’s new and slightly fancier version with the option of a tempered glass side panel.
The Corsair 275R case ships in two varieties: $80 with tempered glass or $70 for acrylic -- at which point the latter is essentially a 270R. The 275R is a refresh, then, and prioritizes tempered glass, a longer PSU shroud that doesn’t abruptly terminate, and rubber grommets. As it differs from the 270R, that would more or less recap the 275R. As its name openly indicates, this is a half-step to something new.
