Microsoft announces its innovative in-chip microfluidic cooling system

Microsoft has successfully tested a
new cooling system that removed heat up to 3x better than cold plates, an advanced cooling technology commonly used today. It uses microfluidics, an approach that brings liquid coolant directly inside the silicon – where the heat is. Tiny channels are etched directly on the back of the silicon chip, creating grooves that allow cooling liquid to flow directly onto the chip and more efficiently remove heat.

Microfluidics are not only innovative but also challenging as it requires ensuring that the channels are deep enough to circulate adequate cooling liquid without clogging while not being so deep as to weaken the silicon such that it risks breaking. Microfluidics also requires designing a leak-proof package for the chip, finding the best coolant formula, testing different etching methods and developing a step-by-step process for adding etching to manufacturing the chips.

Microfluidics have reduced the maximum temperature rise of the silicon inside a GPU by 65%, though this will vary by the type of chip. The team expects the advanced cooling technology would also improve power usage effectiveness, a key metric for measuring how energy efficient a datacenter is, and reduce operational costs.

As part of the prototyping effort, Microsoft collaborated with Swiss startup Corintis to use AI to help optimize a bio-inspired design to cool chips’ hot spots more efficiently than straight up-and-down channels, which they also tested. The bio-design resembles the veins in a leaf or a butterfly wing. 4 prototype designs have been developed so far in 1 year.

BREAKING: Xiaomi Scammed Everyone with Fake “Proprietary” Fast Charging Tech

The Xiaomi 17 Series will officially support 100W universal PPS fast charging and you can use pretty much any PPS charger and get full-speed charging — finally breaking free from Xiaomi’s own charger ecosystem. Meanwhile the Xiaomi smartphones with Surge P1 and P2 fast charging chips uses Xiaomi's proprietary MiPPS protocol for faster charging.

Well, if you’re rooted, there’s a sneaky trick — just run this command:

echo 1 > /sys/class/gcom-battery/pd_verifed

and boom, your phone switches from Xiaomi’s locked-down MiPPS to plain old, public PPS.

So after all this time, Xiaomi’s “special” fast charging was just a rebranded standard protocol, hidden behind a wall to keep users tied to their chargers. A senior CoolAPK user confirmed this hack works on all Surge P1 and P2 devices. In other words, Xiaomi fooled its own fans, making them think they needed proprietary tech, when all along it was just standard PPS with a fancy new name.

This could also be one of the reasons why Xiaomi is so desperate to stop users from rooting their devices by adding 69420 rules for bootloader unlocking.

Specifications:
• 12mm dynamic driver, PMI + TPU diaphragm
• 3 mics & VPU on each bud
• Up to 45db Personalised ANC
• improved wind noise resistance
• Codecs: AAC, SBC, LDAC, Hi-Res audio
• Frequency range: 5000Hz

• Bluetooth 5.4v; IP54 rated
• Dual Connection; In-ear detection
• Battery: 55mA(bud) & 500mAh (case)
• 10hrs (without ANC) / 5.5hrs (with ANC)
• 38hrs (without ANC) / 22hrs (with ANC) with case

Priced at 180$. No word on India launch.
To give you an idea, Nothing Ear (Open) which was launched last year in October 2024 is now launched in India in September 2025 for Rs. 9,999 in Flipkart BBD Sale.
