    One issue I&#x27;ve had with swapping fans for Noctuas is the airflow matching. The louder fans aren&#x27;t louder just because they&#x27;re lower quality (which they definitely are), but also because (almost always in my experience) they force more air through.<p>That unit from the article sounds very temperature sensitive. I&#x27;d be wary of throwing a precision unit like that out of spec and out of calibration.<p>FWIW I&#x27;ve noctua-swapped so many things including an oscilloscope.

    Anyone know why that heatsink is that weird hedgehog spines design and not the more common regular extruded fin?

      The design is called a splayed pin fin heat sink.<p>The rounded pins present minimal resistance to incoming air streams and Incoming air streams can enter from all directions (omnidirectional).<p>Round pins generate extensive air turbulence.<p>I&#x27;m guessing the more splayed the pins, the greater the air turbulence and it allows for air movement in all directions; the time &#x2F; gps chipsets are meant to run cool.

    &gt; And I guess it wouldn&#x27;t be, since it&#x27;s not exactly cheap (they don&#x27;t publish a price for the unit online).<p>Any idea how much it costs?

    I never understood why so many devices were using such poor quality and noisy fans. They fail earlier, they move less air and they&#x27;re noisier. Now I understand there&#x27;s a cost issue, but it&#x27;s not only that: a lot of it is also just poor design &#x2F; poor research &#x2F; poor parts sourcing.<p>For the little story, back in the early beige PC days (think 386 and 486), quiet PC fans didn&#x27;t exist. It was all super noisy, and typically at a fixed speed.<p>And, coming from the Commodore 64 and then Commodore Amiga that were silent machines, this was driving me crazy.<p>So 18 y&#x2F;o me managed to source some proper fans out of Japan (Panaflo fans IIRC) <i>and</i> I went bug my neighbor, who was studying to become a chip engineer...<p>I came to my neighbor with an idea: <i>&quot;Why not lower the fan speed when the PC ain&#x27;t too warm and then only speed it up when the PC gets too warm, you know, like a car&#x27;s fan adapts to temperature?&quot;</i> (cars would do that: they&#x27;d start spinning a huge fan to cool down the water in the car&#x27;s radiator, but only once the water would be too warm).<p>And so my neighbor drew a little electronical circuit and we bought &quot;thermistors&quot;: I would &quot;calibrate&quot; them with boiling water in my mom&#x27;s kitchen and then we&#x27;d install the circuit with the thermistor in the PC&#x27;s PSU, with Panaflo fans.<p>So basically: back in the 386 and then 486 days, I already had quiet PCs. I&#x27;d &quot;muffle&quot; my HDD in an enclosure, opened on top (so that heat could dissipate, on which I&#x27;d put a 7V panaflo fan [I&#x27;d take the 12V and the 5V and create 7V]).<p>Once the PC world began to wake up and the likes of Be Quiet! and Noctua became a real thing, I was delighted. My current main rig has a Be Quiet! PSU and a Noctua fan for the CPU. I cannot thank such companies enough.<p>P.S: for what it&#x27;s worth my neighbor later on moved to southern California and became an early Broadcom employee and he&#x27;s been much more successful than me for he was the real smart cookie. We&#x27;re still friends to this day.
