Cutting Open a Heatsink Heatpipe To See Inside
An anonymous reader writes "Frostytech gets to the heart of Zalman's CNPS11X heatsink by cutting a section of heatpipe from the CPU cooler to inspect its inner composite heatpipe wick structure. Now that's an in-depth heatsink review! Interesting photos of the dissected heatpipe's composite wick — sintered copper powder on top and axial groove wick below — that you're unlikely to see elsewhere. In the late 1960s the first commercial heatpipes were used by NASA to stabilize satellite temperatures; now they stabilize multi-core processors." -
Melamine Ceiling Tiles and the Quiet PC
Delta Screemer writes "What good are ceiling tiles when it comes to making a computer quieter? Well, Max Page of FrostyTech has found a use for 'Melamine Foam Sound Absorbing Ceiling Tiles' as a cheap way of lowering the noise a computer produces. By lining the insides of a computer with these $3 24"x24" industrial office panels he was able to quiet a computer by several dBA. That may not sound like much (pun intended), but when you compare the price of these melamine foam panel to products like Dynamat the price difference is substantial." -

Surface Mapping Athlons For Fun And Knowledge
ryemax writes: "'Surface Mapped Athlon - Is Lapping Required?' is the title of today's bit of insight from FrostyTech. Basically we took an Athlon and measured to within 0.0005" how out-of-whack the surface of the aluminum plate is. With that knowledge and a few hundred values we made a nifty image map of the surface features. With that done, the picture was overlaid atop an image of the processor so all can see where surface flatness may be a problem. Why, you ask? Because I get really annoyed when expensive heatsinks/cold plates get suck on unflat surfaces - and thermal performance gets kicked in the arse. So, rather then just say "it's unflat", I decided to quantitatively prove it using a dial micrometer. Bottom line -- lap that Althon plate." Wow. -
