I'm fairly sure everyone in the history of the internet who's ever asked "does anyone care about X" is actually trying to say "nobody cares about X." Regardless, stores messing up very clear specifications that are easy to retrieve via PSREF is on them. Also, Lenovo having a lot of different products isn't inheritly a bad thing, lol. They aren't the bogeyman, they're a company that sells laptops.

Not disagreeing, but let's make sure the decade old wisdom gets heard in the back: COMPANIES ARE NOT YOUR FRIENDS

Have you ever heard of power limits?

There's no point in disputing your claims if your only argument against mine is "well the internet is wrong and I'm right." I didn't look at Wikipedia either, this is just something I've gathered from experience. Also, if you're saying the XPS 17's cooler is basically the same as the XPS 15's cooler, I'd like you try to run full XPS 17 wattages through the XPS 15's heatpipes and let me know how that goes. (Edit: also yes, Heatpipes and Vapor Chambers are effectively the same thing but in different forms. However, they wouldn't make different forms if there wasn't a benefit to them, and we've seen this benefit in many places. Say what you like, but heatpipes aren't somehow the better solution by default because we're familiar with them.)

Realistically, there's increased surface area between the heat spreader and the vapors inside of the chamber when the chamber itself is the heat spreader. The reduced metal between the liquids and the actual die certainly helps, and the paths vapor can take to get to the radiators are almost infinite compared to bidirectional like heatpipes. Edit: Additionally, the large surface area of the copper vapor chamber can be used to help spread the heat, allowing more liquids to vaporize and cool down the die. Overall, there's just more potential for cooling to occur with a large mass filled with coolant compared to a tube. This isn't just marketing - there's a league of benefits outside of just the materials and basic principals applied here.

I am, yes. Should probably change this account to make that a little more clear. That sucks. Apparently the same thing happened to early purchasers of the AMD Nitro 5. I'd suggest doing some more research into the benefits of vapor chambers. There's a bit more to it than that.

You realize that's literally what I was talking about, right? Yeah, plausible deniability, but it's certainly pretty reckless if your marketing team can't even keep the specs straight. We saw a similar issue back with the ThinkPad T14 where they said the AMD variant had TB3 but no Ethernet for some reason. Completely false, and they luckily caught it before the product launched, but still. Fair enough, sure. Although 10 watts is quite a fair bit, and people were paying for a product with a vapor chamber after all. Some sort of compensation is in order.

Due to the way vapor chambers are designed, they're generally much more efficient at transporting heat than conventional heatpipes. And, in this case, the vapor chamber cooler is what a lot of people bought the Legion 7i for. However, folks are instead receiving a weaker, conventional cooler.

Summary Lenovo has been selling the Legion 7i to customers under the impression that it includes a vapor chamber cooler. However, the vapor chamber cooler is limited to a small subset of models. They neglect to mention this on their site, and as a result it's being called false advertising by angry customers. Image of heatpipe-cooled Legion 7i below in spoiler. Quotes From Reddit... From LQCG... My thoughts This is some terribly misleading marketing from Lenovo. This is especially frustrating given that they've done thing kind of thing before, notably to the 1660TI version of the Legion Y740. Basically, that was supposed to have G-SYNC according to the product page, but all of Lenovo's manuals said it didn't. The software didn't support it either. They ended up refunding people $100 or taking the laptops back if people were that upset. Hopefully Lenovo will step up to the plate and take responsibility here. I'm hoping LTT will cover this given that they just had the Legion 7i on Short Circuit.
