Heat pipes are incredibly efficient thermal management devices used in the construction of most of the CPU coolers Frostytech has reviewed. Though simple in appearance, these thin copper tubes bent into gentle curves literally determine the fate of your computer hardware!

The performance of any heatsink is significantly influenced by the type of wick structure inside the heat pipe used in its manufacture. A wick is essentially a microscopic structure on the inside of the heat pipe whose sole function is to return working fluid by capillary action.

So what goes into an effective heat pipe based CPU cooler?

   "Taiwan-based thermal solutions providers are keenly proceeding with capacity expansions for heat pipes and vapor chambers seeking to meet robust demand for 5G handset applications though the coronavirus outbreak may temporarily weaken sales of the new-generation phones, according to industry sources.

Chaun-Choung Technology is reportedly to expand its production capacity for both kinds of heat dissipation modules at its China plants in Kunshan and Chongqing in the first half of 2020 to better tap 5G-driven business opportunities. Its peers Auras Technology and TaiSol Electronics are also moving to carry out similar capacity expansion plants, the sources said.

Except for Apple, which may continue adopting graphite sheets for 5G iPhones' cooling, other major handset vendors are expected to incorporate either heat pipes or vapor chambers into their sub-6GHz or mmWave 5G models.

Vapor chambers are 3-4 times better than heat pipes in terms of heat dissipation capability and are more expensive, and therefore may be adopted by vendors in their high-end and flagship 5G smartphones while heat pipes may be mostly applied to lower-end 5G models, the sources said.... "

   We review another be quiet! Shadow Rock cooler, this round the Shadow Rock 3. With more simplified looks this cooler comes with a single radiator, one fan and takes and all that offering cooling performance up-to 190 Watts of cooling power, enough for any modern processor and perhaps a bit of tweaking as well.

   Alphacool goes all in on RGB lighting with their all-copper Eisbaer Aurora 360. Not only does this all-in-one liquid cooler deliver reliable performance, but it also allows for optional expansion via quick release fittings and support for the company's Eiswolf product line.

   Shadow Rock is a premium air cooler series from be quiet!’s range of high-performance CPU coolers. The series has been running for a number of years now and has seen various iterations of the Shadow Rock introduced, including top flow and low-profile variants as well as traditional single tower air coolers. The new Shadow Rock 3 is the latest single tower air cooler from be quiet! that offers improvements over the previous Shadow Rock 2.

   It may not be their best looking CPU cooler to date but the brand new and rather affordable Shadow Rock 3 by be quiet! delivers impressive cooling efficiency with low noise levels and all that at a very attractive price point.

   The latest revision is available in 3 radiator sizes, with 360mm, 280mm and 240mm, being the X73, X63 and X53 respectively. Today we’re looking at the Kraken X53, priced almost identically to several of CORSAIR’s 240mm offerings, who are arguably the one to beat in this segment.

   The latest Chromax.Black line of CPU Coolers by Noctua includes the award winning NH-U12S model which is the 2nd model of that line to end up on our test bench.

   "When we met up with Alphacool at CES 2020, we saw quite a few new products that were slated to release in the upcoming months. Everything from super-thin ARGB LED strips, new GPU water blocks, and even a new AIO model, the Eisbaer Aurora. Well, it’s a few months later, and we are here today with the 360mm version of the Alphacool Eisbaer Aurora CPU AIO. The Eisbaer Aurora is the successor to the Eisbaer and Eisbaer XT lines, adding DRGB lighting and multiple performance-enhancing changes to the design. Follow along as we take a closer look at the 360mm version of the Eisbaer Aurora!"

   Alphacool has offered its Eisbaer all-in-one CPU coolers in various forms over the years and has just released a brand-new version. The new Alphacool Eisbaer Aurora series provides a few new features over the previous versions and now includes RGB lighting areas on both the fans and the CPU block, to give it a more up to date and stylish appearance.

   We are reviewing an AIO cooler from Corsair: the H115i RGB PRO XT. It’s a new version of a product that’s been available on the market for about two years the, H115i Pro. It’s a 280 mm AIO with an aluminium radiator and pump coupled into a single loop and cooled by a set of two fans (140 mm fan size).

   CORSAIR adds to their Hydro X series of custom watercooling products with their second pump/reservoir combo. The all-new Hydro XD3 uses a Xylem DDC and a lower profile form factor to complement the taller Hydro XD5 that used the Xylem D5, and adds more RGB while sticking with the same excellent installation options.

   Deepcool has delivered a monster with the Gamer Storm Assassin III. This latest air cooler is comprised of two 140 mm fans and a massive dual-stack heatsink, leaving the ARGB lighting craze behind. Instead, Deepcool has focused on offering users maximum performance, which the cooler handily delivers.

   ID-Cooling looks to dominate the entry level cooler market by giving users a traditional tower cooler with an emphasis on solid performance in the SE 224 XT Basic. Taking things a step further, they add LED lighting with the appropriately dubbed SE 224 XT ARGB. Both versions certainly gave the competition a pummeling.

   Perhaps the most requested CPU water block review in years, we finally take a look at Optimus Water Cooling's Foundation CPU block. With a near-rabid user base touting praises galore, we put it to the test to see if the hype and asking price is justified.

   Alongside the Optimus Foundation CPU block, we saw it fit to also cover the company's flagship Signature CPU block. In its second version, the Signature V2 for Intel CPU sockets features to good effect a thick unibody brass top and mounting bracket, as well as the cooling engine and other features of their Foundation block.

   The brand new Mugen 5 Black RGB CPU Cooler by Scythe may not share the same impressive looks and cooling efficiency as the Mugen 5 ARGB Plus but thanks to its very good price/performance ratio and the Kaze Flex 120 RGB PWM fan it’s still certainly worth checking out.
