In addition to cases and massive amounts of RGB Cooler Master had a prototype closed loop cooler on display at Computex that combines an all in one liquid cooling loop with a TEC element that cools the water to sub-ambient temperatures.
TechPowerUp snapped photos from the show floor.
Thermoelectric coolers aren't anything new (and this isn't Cooler Master's first foray with TECs), but the hybrid approach is an interesting one. The AIO loop appears to work like a water chiller cooler would with the TEC not having direct contact with the processor but rather it is used to give the single 120mm liquid loop radiator a boost by pulling lots of heat out of the water before hitting the radiator. According to Computex attendees the loop order flows from the CPU block to the TEC element where water is passed across one side of the side and the other hot side is cooled by a large heatsink which uses four heatpipes and dual fin stacks along with two fans in a package about the size of a 240mm radiator. From there, the chilled water passes through a traditional water cooling radiator and then the cool water goes to the CPU block.
The thermoelectric cooler uses the Peltier effect where electricity (DC) is passed between an array of thermocouples that sit between two layers (usually ceramics) creating an effect where heat is drawn from one side to the other with the cool side able to be cooled below ambient temperatures while the hot side needs to be cooled by a heatsink to prevent it from overheating and reducing efficiency and/or damaging the materials.
According to PC World, Cooler Master has stated that their prototype TEC will be rated at 300W TDP which is quite a bit higher than the approximately 180W of a 240mm traditional AIO. Gordon Mah Ung was able to perform some cursory testing with a FLIR camera attached to his smartphone where he saw the cooler demonstrate its ability to cool the water used in the loop 10 to 15-degrees below ambient where it was around 80°F (~26.7°C) in the packed Computex show floor and 64 to 70°F for the water as measured by the FLIR when pointing at the radiator and tubing. Further, Cooler Master had a temperature probe at the CPU block where it measured 20°C (likely no heat load as no processor was hooked up heh). This boosted cooling performance does come with a tradeoff, however. The TEC's hot side will need to be cooled (noise) and the TEC itself will draw as much as 150W of power (it will use standard connectors that a PC PSU can drive) in order to work its cooling magic (so higher electricity usage/cost).
My first thought was that the hybrid cooler could prove useful in a SFF system by offering cooling potential that would just otherwise not be possible in the form factor with the thinking that the cooler would not need to cool to crazy low temperatures, but just enough to match the performance of a much larger water cooling loop. Gordon Mah Ung from PC World also posits that the cooler would be useful in situations where ambient temperatures are very high (say, summer months in the south with no or underpowered AC) as the TEC would be able to keep processor temperatures in check (allowing enthusiasts to maintain their overclock or at least keep stock clocks and Turbo Boost without thermal throttling) where air cooling or water cooling cannot as the best they can do is cool to ambient.
Apparently, the hybrid cooler will also be able to push things if you do want to go for higher overclocks for benchmarking runs or improved gaming performance.
One concern with thermoelectric and other sub-ambient cooling methods is condensation which can build up on the outside of cool parts like the tubing and blocks and can potentially cause instability or damage to PC components. Traditionally, the tubing and area around the CPU socket would need to be insulated to protect from this. Cooler Master's design, I don't think, is immune to this but by moving the TEC away from the processor and using it to cool the water (so no direct contact), it is allegedly much less of an issue and if the TEC is just used to provide a bit of a boost to the water loop rather than going for as low temperatures as possible the risk should be minimal.
There is no word on specific pricing or release dates, but several sites are reporting that it will be available later this year with "competitive pricing". I would guess this cooler is going to be at the high end of water cooling AIOs and expandable kits at minimum which is to say probably around $300+. (Looking on Amazon, EKWB kit with 360mm radiator is $370, you can find kits with 240mm radiators for between two-to-three hundred dollars, and a used custom loop starts around there if you find a forum deal.)
What do you think about this cooler? I am interested in seeing the reviews on this and whether it is able to combine the best of both water and TEC cooling worlds.

In an interview with AMD Senior Vice President Jim Anderson, PC World's Gordon Mah Ung got the chance to discuss and get hands on with second generation Threadripper as well as AMD's new Wraith Ripper air cooler. Developed in partnership with Cooler Master, the Wraith Ripper is a massive air cooler capable of keeping even the upcoming 32 core Threadripper processor cool (allegedly a 250W TDP part!) which, as Jim Anderson notes, has all four dies on the package being used (first generation Threadripper used two hot dies and two spacers).
The behemoth features a full cover block for Threadripper that connects to a very dense aluminum fin stack using 14 nickel plated copper heatpipes. There is a single fan in the center of the fin stack hiding under a black fan shroud that covers the top and left and right sides. The black shroud also holds the customizable RGB lighting which lights up the logo and outline around the edges of the shroud. The fan is allegedly rated at 39 dBa which is pretty good considering the amount of heat it needs to dissipate from Threadripper CPUs. Likely due to the HSF's sheer size Cooler Master was able to go with a larger and slower spinning fan.
Other details like weight, cost, and release date are still unknown though it does appear to have some heft to it! It should be available later this year following the Q3 launch of second generation Threadripper though it will work fine with first generation Threadripper processors as well as they use the same TR4 socket.

Cooler Master demonstrates their love of tempered glass with the MasterCase H500M, all four sides are made of it with the installation of the front panel up to you depending if you prefer looks to airflow. The case ships with a pair of 200mm fans in the front and a single 140mm in the rear, you can replace the front with a radiator of up to 360mm, the top also supports radiators of that size as well. Cable management is well executed, with a cover for almost every component and wiring path, though it takes some effort to install them all. Apart from a few minor issues Guru of 3D loved this case, check it out in all it's glory here.
"Join us in a review the new MasterCase H500M from Cooler Master. The new chassis has that familiar in-house CM feel, yet was brought into the year 2018 with some nice modern features and the ability to go all stealth with the stuff you do not want to show. Intrigued? Sure you are, let's have a look, shall we?"

We've seen the PR for the Cooler Master Mastercase H500P Mesh but this review from Guru 3D may be the first time we see it in action. While it is a mid-tower there is enough space inside to fit an E-ATX motherboard and believe it or not those front fans are 200mm in size, with 140mm on the backside. The interior design is impressively spacious, with drive mounts flush to the top of the case and additional ones hidden in the PSU shroud there is a lot of empty space apparent even after Modders Inc installed their full system.
For $150, this case is worth taking a look at.
"Companies are constantly coming up with new ways to dispel that heat and ensure those massive gaming systems are ice cold. Cooler Master has presented us with one of their latest innovations that will help solve this problem, The Cooler Master Mastercase H500P Mesh."

Tagged: tr4, Threadripper, MASTERAIR MA621P, cooler master, amd, air cooler
So far we have mostly seen reviews of watercoolers for Threadripper but there is an air cooler designed to tame this multi-threaded beast. The Cooler Master MASTERAIR MA621P is one such heatsink, a 1.2kg beast with two fans. [H]ard|OCP's testing shows this cooler to be capable of cooling your 1950X at stock speeds, but do not expect the overclocks an AiO watercooler allows. The installation is a bit of a challenge but this is the least expensive cooler for Threadripper, as well as being the only air cooler for it from CM. Check the full review to get a closer look at this large chunk of metal.
"The AMD Ryzen Threadripper is a beast when it comes to overclocking and cooling. Cooler Master steps into the ring with the first Threadripper-specific air cooler that we have come across. We have put it through the paces here on our highly overclocked and overvolted 1950X. Does the MasterAir MA621P have what it takes?"

Follow their trend of shoehorning Master into the name of all of their products, Cooler Master have release the MasterMouse MM520. As you can see they did not follow the pack and have created a different looking and feeling mouse. If you have mastered the claw grip, then this mouse is designed specifically for you; if not take a look at some of the comparison shots TechPowerUp posted to get an idea how the shape of this mouse differs from the norm. Technically the mouse should appear, it uses the PWM3360 optical sensor and PBT main buttons however the shape is going to play a part in your enjoyment of this rodent.
"Cooler Master's MM520 mouse uses great materials, a top optical sensor, and features highly customizable RGB lighting. While the shape might not be for everyone, it could be your top weapon of choice for all different kinds of game genres."

Tagged: cooler master, ML120L RGB, AIO, Master Liquid Lite
Cooler Master have released a new ML120L RGB AiO watercooler with a price tag of $60, intended to tempt those thinking about trying this style of cooler without increasing their cooling budget noticeably. The 120mm radiator will fit in the vast majority of cases, budget and flagship and is compatible with all modern processors. [H]ard|OCP tested the cooler with a Ryzen 7 1700 and found a really winner from a price to performance perspective. It is neither the most effective AiO cooler nor the quietest but from a value perspective it easily matches or beats even popular air coolers.
"Cooler Master has recently revamped its entire line of All-In-One liquid CPU coolers, and it has specifically addressed putting a lower priced product into the market with its "Lite" series of AIOs that it says are "An easy, reliable and low noise plunge into liquid cooling." Let's see how its smallest radiator stands up to an overclocked Ryzen CPU."

Tagged: ML240 SMART, MasterLiquid, MasterCase, MasterAir, MA410M, H500P, H500M, G100M, cooler master, CES 2018
Cooler Master have started out their announcements at CES with several coolers and a fair sized allotment of case models. First up is an aircooler designed for SFF systems, the MasterAir G100M and its horizontally mounted fan.
The entire cooler stands 46.3mm tall, perfect for slim cases and still manages to cool processors of up to 130W TDP. It does of course bear RGBs for those who like a warm glow from their coolers.
For those who want a bit more lighting options for water or air cooling, the new MasterLiquid ML240 SMART and MasterAir MA410M are the ones you want to pick up. Not only do you get 16.7 million colours of RGB but you can use the SMART temperature detection feature to have your colours change accordingly.
The MasterCase H500M and 500P share similar capabilities, windowed sides and a pair of 200mm RGB fans at the front for airflow and aesthetics, a PSU shroud, cable covering accessories and support for radiators up to 360mm. To differentiate them, the H500M offers more connectivity at the front, a Type-C USB, four USB 3.0 ports and two 3.5mm jacks while the H500P is for more stylish designs and offers you the ability to mount your GPU vertically.
The MasterBox Q300P and Q300L offer some mobility for those who move their systems on a regular schedule. The I/O panel you see on the side can be placed in six different locations and the case itself is happy sideways or upside down, depending on your preference. The four carrying handles you see are removable if you so desire.
The MasterBox MB500 and TD500L offer a somewhat different look on the front and with a little work you can have your RGBs offer different highlights depending on the view angle of the system. These are also large enough to offer six 120mm fans or their equivalent in radiators, GPUs of up to 407mm will fit in the case and there is 19mm of space between the motherboard tray and side panel to give you enough space to get creative.
There are also updates to the MasterCase MC-Series which come with the M-Port for extra options in your design as well as the Trooper SE and Stryker SE line ups which we may see more of over the week.
Introduction and Features
Cooler Master recently updated the MasterWatt Series, which now includes four new MasterWatt power supplies ranging in output capacity from 450W up to 750W. All four power supplies feature semi-fanless operation, modular cables, 80 Plus Bronze level efficiency, and come backed with a 5-year warranty. Note: the two MasterWatt Maker 1200W PSUs are 80 Plus Titanium certified and come with a 7-year warranty while the two MasterWatt Lite PSUs are 80 Plus white, have fixed cables and come with a 3-year warranty. We will be taking a detailed look at the MasterWatt 550W PSU in this review.
Cooler Master MasterWatt 550W PSU Key Features:
• 550W Continuous DC output at up to 40°C
• Semi-fanless operation (under 15% load)

Here is what Cooler Master has to say about their new MasterWatt PSUs:
“The MasterWatt is a 80 Plus Bronze power supply with an innovative semi-fanless mode. Under 15% load, the MasterWatt fan remains idle, offering zero dBA. When demand for power increases, a gradual fan curve provides measured cooling with little to no noise at any output level. Dual forward / DC-to-DC topology are employed to keep the voltage stable in all conditions. For increased performance, MaterWatt is equipped with 16 AWG power cables, which reduce resistance thereby increasing efficiency.”

Tagged: MasterBox MB600L, MasterCase H500P, cooler master
Today CoolerMaster announced two cases, the MasterCase H500P and MasterBox MB600L and there are already some reviews of the MasterCase posted, which you can see below. The MasterBox MB600L is larger and less flamboyant than the MasterCase and is a better choice for those of us who prefer less RGBs in their lives.
The MB600L will accommodate GPUs of up to 400mm, heatsinks 160mm in height or radiators of 360mm if you prefer watercooling. You can get the MB600L in red, blue and gunmetal exteriors and there will be models with an optical bay if you do still use DVDs. The case will sell for $50 and is available now.
The MasterCase H500P is for those who want a case that stands out, the front panel shows off two 200mm RGB fans which can be controlled from compatible motherboards and there is space for two more to be installed on the top. If you prefer watercooling, you can replace the fans in both positions with up to a 360mm radiator. There are two PCI slots at the rear of the H500P so you can vertically mount your GPU to show it off, without needing additional brackets.
You can see some reviews of the MasterCase below.
