Katana bottom cover with active cooling. 65 degrees max.

[msevcov8155702de]

I am currently working on a custom bottom cover for the Katana 17 B12V, featuring active heat dissipation and noise reduction. We are currently redesigning the vents to improve airflow and sound dampening. I expect to have photos of the finished product in about two weeks. Right now, the coolers are already mounted, but there isn't much to show yet. In the meantime, check out these thermal results: https://gpuscore.top/furmark/show.php?id=1702321
Forgot to mention: the rear is raised by 20mm, which is actually quite ergonomic. It mounts into the stock slots and uses a separate power supply with adjustable fan speeds and independent startup for each cooler.

I’m currently working on a custom bottom cover for the Katana 17 B12V, focused on active heat dissipation and noise reduction. Right now we’re in the middle of redesigning the vent geometry to improve airflow efficiency while also reducing turbulence and fan noise. I expect to have proper photos of the finished product in about two weeks — at the moment the coolers are already mounted, but visually, there isn’t much worth showing yet.

In the meantime, here are some thermal results under heavy load:

This was tested using FurMark with 4× MSAA, so it represents a worst-case scenario. GPU temperatures leveled off at ~67 °C, even though the ambient room temperature was fairly high. Importantly, temps stabilized rather than continuing to climb, which suggests the cooling system is reaching a steady thermal equilibrium instead of flirting with throttling.

A few additional design details:

• The rear of the laptop is raised by 20 mm, which noticeably improves both airflow and ergonomics.
• The cover mounts directly into the stock chassis slots — no permanent modifications.
• A separate external power supply powers the cooling.
• Each cooler has an independent startup and adjustable fan speed, allowing fine-tuning for noise vs. performance.

The full FurMark screenshot doesn’t fit in one image, so I’ll post a cropped section for now. Once the vent redesign is finalized and the cover is finished, I’ll share full photos and more detailed measurements
