Cool it! We talk laptop thermals with an expert from Dell



That high-performance CPU or GPU you're eyeballing for your next laptop is nothing if it's not backed by an effective cooling system. Yet consumers tend to know very little about the cooling in a laptop.

We fortunately had time to catch up with Dell's Travis North, who works as a Thermal Engineering Technologist. North answers our burning questions on whether a heat pipe is better than a vapor chamber, whether you should re-paste a laptop, is 100 degrees too hot, and more.

In the first section, North talks about a Dell patent on laptop cooling. You can watch the interview below or on YouTube at this link.

Tribit XFree Go headphone review: Amazing sound, great price, and one glaring flaw

The Tribit XFree Go headphones punch far above their weight, sonically: sadly, the controls locked up after an hour or so of sustained use.

Adios, Wraith? Why AMD's XT chips signal doom for a key Ryzen selling point



With the launch of its slightly faster, slightly better, exactly-the-same-price Ryzen 3000 XT processors this week, AMD became just a bit more like Intel…and Nvidia. More importantly, I suspect these new CPUs may exist to set the stage for removing a key AMD value proposition from next-gen “Zen 3” Ryzen CPUs.

Whither goest thou, Wraith?


Most Ryzen XT reviews landed, well, not with a thud necessarily, but at least a loud “meh”—though Gamers Nexus did say, “we think the sand could have been better put to use elsewhere,” when promoting its Ryzen 7 3800XT review. But the general sentiment is that they’re fine. Ryzen XT processors offer mild 100MHz to 200MHz clock speed increases over their non-XT namesakes, and a higher overall level of silicon quality, meaning they can hold those faster clocks for longer and overclock better. Cool stuff! Yet not cool enough generally to recommend, given their steep $80ish price premium over the standard X-series chips, which remain on the market.

PC market surges as coronavirus forces working from home



As consumers sheltered in place during the second quarter, they bought PCs by the ton. Both Gartner and IDC research firms reported big positive swings in PC and Chromebook sales for the second quarter. Gartner reported a 2.8 percent year-over-year increase, while IDC reported a whopping 11.2-percent boost for the same period.

The two firms have long differed in methodology: IDC includes Chromebook sales, and Gartner does not. That’s significant, as U.S. consumers bought PCs and Chromebooks as students and workers alike weathered the coronavirus. IDC reported unit sales of 21 million in United States, calling it a “double-digit” increase (the firm did not release the exact figure).

Microsoft's Surface devices are now receiving the Windows 10 May 2020 Update (Update: not yet)



Microsoft says it has patched a bug that may have prevented some of its most recent Surface devices from receiving the Windows 10 May 2020 Update. And as of July 1, our Surface devices in our review stable are saying that they can receive the May 2020 Update as a result.

That may be an anomaly, however. ZDNet's Mary Jo Foley reports on July 10 that even though Microsoft says that Surfaces can receive the update, they haven't been.

In its list of issues associated with the Windows 10 May 2020 Update, Microsoft notes that it recently deployed patch KB4557957, which addresses the “Errors or unexpected restarts for some devices using Always On, Always Connected.”

That may be an anomaly, however. ZDNet's Mary Jo Foley reports on July 10 that even though Microsoft says that Surfaces can receive the update, they haven't been. The problem, we're told, is that there still may be a separate compatibility problem in place that Microsoft will maintain until it's sure it has a good update experience. Even with no other safeguards in place, it can still take 48 hours before the May 2020 Update is offered.
