Amazon has found its 'own way' to cool down Nvidia's AI graphics cards
Amazon Web Services
(AWS), stated in a YouTube video that commercially available cooling equipment was not suitable and building data centres with widespread liquid cooling would have taken too much time. This led
Amazon
to develop its methods that can better manage the heat from these power-intensive Nvidia GPUs.
What the AWS VP said about these tools developed for Nvidia GPUs
Talking about the cooling equipment available for AI GPUs in the video, Brown said: 'They would take up too much data centre floor space or increase water usage substantially. And while some of these solutions could work for lower volumes at other providers, they simply wouldn't be enough liquid-cooling capacity to support our scale.'
So, instead of relying on conventional solutions, Amazon engineers developed the
In-Row Heat Exchanger
(IRHX), a cooling system that can be integrated into both existing and future data centres. Previously, these traditional air cooling methods have been sufficient for earlier Nvidia chip generations.

In a blog post, Brown also confirmed that AWS customers can now access this updated infrastructure through new P6e computing instances. These new offerings support Nvidia's high-density computing architecture, particularly the GB200 NVL72, which consolidates 72 Nvidia Blackwell GPUs into a single rack for training and deploying large AI models.
Previously, similar Nvidia GB200 NVL72-based clusters were available via Microsoft and CoreWeave. AWS, as the leading global cloud infrastructure provider, continues to enhance its capabilities.
Amazon has a history of developing its infrastructure hardware, including custom chips for general computing and AI, along with in-house-designed storage servers and networking equipment.
This approach reduces reliance on external vendors and can improve profitability. AWS posted its highest operating margin since at least 2014 during the first quarter, contributing significantly to Amazon's overall net income.
Microsoft, the second-largest cloud provider, has also moved into custom hardware. In 2023, it introduced a cooling system called Sidekicks, tailored for its Maia AI chips.

Why Nvidia's AI chip plans for China may not go as planned
Nvidia may have been hit with a 'new' problem with resuming export of its AI chips to China. The US-based company, which was recently given a go-ahead to restart the sales of H20 AI chips to the region, has reportedly informed its Chinese customers of limited supplies for the chips. H20 is the most powerful AI processor the semiconductor company has been permitted to sell to the country under US export restrictions. According to a report by The Information, the supply constraints stem from an April US government ban on H20 chip sales. Citing two sources, the report claims that this ban compelled Nvidia to void existing customer orders and cancel manufacturing capacity previously booked with chipmaker Taiwan Semiconductor Manufacturing (TSMC). Nvidia CEO Jensen Huang stated at a Beijing media event last week that TSMC had subsequently reallocated its H20 production lines to produce other chips for different clients. Resuming manufacturing of Nvidia H20 chips may take time The report said that manufacturing new H20 chips from scratch could now take up to nine months. Moreover, Nvidia reportedly does not plan to restart H20 production, though the report did not cite specific sources for this detail. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like An engineer reveals: One simple trick to get internet without a subscription Techno Mag Learn More Undo Despite these reported supply issues, Huang recently commented that Nvidia would ramp up H20 chip supply and that licenses for Chinese orders would be swiftly approved. This comes just days after Nvidia announced its intent to resume H20 sales to the region, pending US government export license approvals. Huang also met with US President Donald Trump in the Oval Office last week to advocate for restarting sales of his company's specialised AI chips to China. Citing two individuals familiar with the meeting, The New York Times reported that Huang argued that American-made chips should remain the global standard. He is also said to have contended that the US would be making an error by ceding the massive Chinese market to homegrown competitors.

Meet the people who don't skip ads online
Last month, Amazon Prime Video introduced ads to its subscription tier in India. You can still go ad-free, it'll just cost an additional ₹ 129 per month on top of the existing ₹ 299 monthly plan. Naturally, a section of the internet wasn't thrilled. Every time there's a furore around ads interrupting our content experience, I can't help but think of a set of people for whom this is just another day at work. Media planners, marketing consultants and ad strategists have to sit through ads not because they can't afford to go ad-free, but because it's part of the job. Their work requires constant monitoring of ads across platforms. Exposure becomes essential market research, almost like an audit, some of them tell me. It helps them advise clients, track competitor strategies, and stay on top of where brands are showing up. And over time, this constant exposure shapes how they consume media. Mumbai-based Geetanjali Bhattacharji, who's spent over three decades in media and marketing, says it often feels like being 'stuck at a party where everyone's trying to sell you something.' Bhattacharji is the founder of Glassbox Ventures, a business and strategy consultancy. 'Sometimes I wonder if I'm reading the news or just a cleverly disguised commercial,' she says. The result? 'It's made me a more cautious and selective media consumer, and maybe a little more cynical too.' For Aditi M, a digital marketing professional from Mumbai, the impact is different. 'YouTube is my primary music platform, and the newer mid-video unskippable ads have made the experience of listening to a song a lot more annoying,' she says. As part of her job, she still has to watch and analyse those ads for potential client opportunities. I relate to this, too. I've resisted getting YouTube Premium even though I pay for Spotify. My reasoning: what kind of brands are allocating ad dollars to the world's biggest video-streaming platform tells you a lot about the state of business and the role of digital media in it. And the content of the ads—the plot, the meme references, the casting—reveals how storytelling is evolving and culture is shifting. Besides, ads on Spotify are torture, with their repetitive storylines. No wonder it is widely suspected to be a clever nudge to make people buy the subscription. Aditi's occupational hazard extends beyond YouTube. Early in her career, she worked on seeding branded content into films—figuring out how to integrate products into scenes without disrupting the narrative. 'You'd spend weeks trying to get a placement just right,' she recalls. By the time the film was released, she'd be so immersed in the mechanics of selling that she no longer wanted to watch it. 'I see every piece of content from a sales perspective now. It's off-putting, but you can't help it.' What feels like forced ad consumption to some is a source of curiosity for digital media veteran Karthik Nagarajan, even two decades into the business. 'I consider myself a great target for ads,' says Chennai-based Nagarajan, CEO of Hogarth India, a WPP-owned content company. When an ad influences him, he breaks it down to understand why. 'Tapping into your instincts as a consumer gives you an edge as a marketer,' he says. 'Further, I don't just see ads through an audit lens—they're also a form of art,' he adds. Either way, ad-watchers make you appreciate that not all viewers have the luxury of being annoyed by ads. Some are too busy taking notes.
