Noctua's low profile NH-L9x65 heatsink stands just 64mm tall and has a very compact footprint of only 95x95mm. The NH-L9x65 is designed to cool some fairly intensive Intel sockets, along with the full spectrum of AMD processors and APUs. Compact CPU coolers can be a little tricky to install, but Noctua long ago laid down the framework of an excellent motherboard mounting system,, so the NH-L9x65 is a breeze to work with. 

The Noctua NH-D9DXi4-3U is a mid-sized heatsink designed specifically for lower noise cooling of Intel Xeon processors in 3U height computer/server chassis. It's compact stature makes it ideal for rack mounted computers in a recording studio, video editing suite, operations control center... The 920gram Scythe Fuma heatsink is constructed around six 6mm diameter copper heatpipes and a pair of aluminum fin stacks that measure 104x130x37mm (HxWxD) in size. The heatpipes are liberally soldered to a chunky nickel plated copper base plate, this plate helps to more evenly conduct heat away from hot-spot ridden multi-core CPUs. While Scythe doesn't overtly market its heatsinks as DeepCool's Maelstrom 240 is a self contained CPU liquid 
cooling system consists of a dual fan, 240mm wide aluminum heat 
exchanger and combination pump head / skived copper waterblock. With Frostytech's synthetic thermal test platforms applying up to a 200W heat load, only we can accurately rank how the Maelstrom 240 liquid cooler stacks up

Thermaltake decided to jump on the RGB wagon by taking their very successful Water 3.0 Ultimate AIO liquid CPU cooler and replacing its regular high-speed fans with their ultra-low noise Riing RGB ones. The result may not produce the exact same cooling efficiency numbers but it looks great and is almost whisper quiet even at load.

"We have seen TEC/Peltier products in the past, and even reviewed them in years gone by; but implementing this kind of cooling technology in a consumer CPU cooler has obviously not resulted in a shift in the cooler market to this point. Closed-loop liquid CPU coolers have become commonplace, standard air cooling is better (and increasingly less noisy) than ever, and in general the need for TEC coolers just has not been felt for consumer CPU cooling.

www.frostytech.com

I think what Phononic has done with the HEX 2.0 is show the advantage of a TEC in a demanding small form-factor implementation, where liquid coolers will not always fit. A great example of this is a case I have in for review currently: the Lian Li PC-Q17. The only way to install a liquid solution like the Corsair H75 (which I used as a liquid cooler comparison in benchmarks) in the PC-Q17 is to mount it outside of the enclosure, just as with the In Win 901 mini-ITX enclosure I reviewed (way back in 2014).

In enclosures like these a small solution is required for a streamlined build, and the HEX 2.0 is a great liquid alternative here."

Hot on the heels of our Cryorig H7 review we are looking today at the R1 Ultimate. A monster of an air cooler, the R1 Ultimate features twin 140mm fans, along with 7 copper heatpipes, while it measures nearly 170mm tall. If you want the best performance without buying a liquid cooler, could this be the answer?

Ryzen 7 has already proven to be a worthy contender for Intel’s LGA 2011-3 set of processors thanks to its similar, or sometimes better, performance levels and significantly cheaper cost. That metric is stretched even further with the 8C16T Ryzen 7 1700 that ships at just £330. At a relative bargain price compared to the higher-end Ryzen 7 SKUs, never mind Intel’s £1000 octa-core part, Ryzen 7 1700 operates at a reduced clock speed out-of-the-box and is given a 65W TDP rating. You also get a decent Wraith Spire CPU cooler thrown into the bundle.

"The liquid state allows the metal – eutectic GaIn alloy – to deform with the surrounding rubber at room temperature. The important characteristics are: <100kPa stiffness, 9.8W/mK conductivity, 6x extension capability, electrical insulation" reports electronicsweekly.com

www.frostytech.com
The research paper behind 'Thubber', High thermal conductivity in soft elastomers with elongated liquid metal inclusions mentions the following salient point: "...heat transport within soft materials is limited by the dynamics of phonon transport, which results in a trade-off between thermal conductivity and compliance. We overcome this by engineering an elastomer composite embedded with elongated inclusions of liquid metal (LM) that function as thermally conductive pathways. These composites exhibit an extraordinary combination of low stiffness (<100 kPa), high strain limit (>600%), and metal-like thermal conductivity (up to 9.8 W·m-1·K-1) that far exceeds any other soft materials."

Written by Chi-Chuan Wang from the Department of Mechanical Engineering, National Chiao Tung University, Taiwan, this paper entitled A Quick Overview of Compact Air-Cooled Heat Sinks Applicable for Electronic Cooling—Recent Progress provides a comprehensive overview of innovative techniques and design elements used to extend the efficiency of air cooled heatsinks. The full paper is available here.

Here's the abstract: "This study provides an overview regarding enhancement of an air-cooled heat sink applicable for electronic cooling subject to cross-flow forced convection. Some novel designs and associated problems in air-cooled heat sinks are discussed, including the drawback of adding surfaces, utilization of porous surfaces such as metal foam or carbon foam, problems and suitable applicable range of highly interrupted surfaces (louver or slit) and longitudinal vortex generator. Though the metal foam may accommodate significant surface area, it is comparatively ineffective for air-cooling application due to its much lower fin efficiency, and this shortcoming can be improved by integrating with solid fin. For highly dense fin spacing (e.g., <1.0 mm), cannelure or grooved surface may be a better choice, and fin structure with periodic contraction and expansion may not be suitable for it introduces additional pressure drop penalty. The partial bypass concept, which manipulates a larger temperature difference at the trailing part of heat sink, can be implemented to significantly reduce the pressure drop. Through some certain niche operation, t the thermal resistance of the partial bypass heat sink may be superior to the conventional heat sink. The trapezoid fin surface featuring easier manufacturing and a smaller weight is shown to have competitive performance against traditional rectangular fin geometry. The IPFM (Interleaved Parallelogram Fin Module) design which combines two different geometrical fins with the odd number fins being rectangular shape, and parallelogram shape in even fin numbers, shows 8%–12% less surface than conventional design but still offers a lower thermal resistance than the conventional rectangular heat sink in lower flowrate operation.

The cross-cut design shows appreciable improvements as compared to the conventional plate fin design especially in high velocity regime and the single cross-cut heat sinks are superior to multiple cross-cut heat sinks."

With the introduction of the Intel Kaby Lake processors and Intel Z270 chipset, unprecedented overclocking became the norm. The new processors easily hit a core speed of 5.0GHz with little more than CPU core voltage tweaking. This overclocking performance increase came with a price tag. The Kaby Lake processor runs significantly hotter than previous generation processors, a seeming reversal in temperature trends from previous generation Intel CPUs. At stock settings, the individual cores in the CPU were recording in testing at hitting up to 65C - and that's with a high performance water loop cooling the processor. Per reports from various enthusiasts sites, Intel used inferior TIM (thermal interface material) in between the CPU die and underside of the CPU heat spreader, leading to increased temperatures when compared with previous CPU generations (in particular Skylake). This temperature increase did not affect overclocking much since the CPU will hit 5.0GHz speed easily, but does impact the means necessary to hit those performance levels.
