MSI Crosshair 15 (B12Ux) review

More than anything, MSI is known for using one platform for many of its devices. This is not new, as we’ve seen it in the past. Also, a lot of car manufacturers do the same thing. In a way, you can think of MSI as VW. For instance, the laptop we’re going to review today shares the same platform as the Pulse GL66.

This is why we were very intrigued when we saw the specs. These guys managed to fit an RTX 3070 Ti with a 140W TGP inside of the Crosshair 15 (B12Ux). We really hope that they have found a way to cool it down properly because the Pulse series is not really known for its great thermals.

Before we go there, we have to mention that the laptop can be paired with a Core i7-12700H, which is the new CPU champion in the mobile world. Also, you get an option of a QHD 165Hz IPS panel. In this regard, it can’t disappoint.

All MSI Crosshair 15 (12Ux) configurations


What’s in the box?

Inside the package, you will find the mandatory paperwork, as well as a 240W power adapter.

Design and construction

The Crosshair 15 (B12Ux) has a very distinct paint job. Instead of the toned-down colors, you get a combination of black and bright yellow. Actually, MSI did this to celebrate the latest Tom Clancy title – Rainbow Six Extraction from Ubisoft.

Its lid is made out of aluminum and has a rather lowkey design, compared to the colorful, contrasty base. Respectively, the latter is made out of plastic. Generally, the laptop feels rigid. However, the base produces some weird noises when you twist it.

Thankfully, the metal cover of the lid makes it more resistant to flex. Even though you can open the display with a single hand, the hinges are not very stable and continue bouncing for ages after you accidentally bump into your desk. On the bright side, the unit sports an HD Web camera, which is a big advantage compared to the ASUS ROG Strix G15.

Moving to the base, we see the notorious paintwork. It features a gradient from Yellow to Black that goes through the keyboard. A keyboard that has the so-called “Spectrum” backlight, which displays different colors, but you won’t be able to change them. Indeed, it looks cool, and its WASD keys are glowing in bright yellow as well.

You don’t need to be very observant to see that this is a very obnoxious device. Unfortunately, we were not very satisfied with the keyboard, whose key travel is okay, but the feedback is a bit soft. Looking at the touchpad, we see more of the same – small size, not the best click, but a very smooth gliding experience.

Lastly, let’s check out the bottom panel. It houses the speaker cutouts, as well as the ventilation grill, which is so big, that you can see parts of the cooling elements inside. The hot air here is exhausted through three vents – one on the left side, and two on the back.


On the left side, there is the power plug, and two USB Type-A ports – one is 3.2 (Gen. 1), while the other is 2.0. The rest of the I/O is situated on the right. There, you will find a LAN port, an HDMI connector, a USB Type-C 3.2 (Gen. 1) port, a USB Type-A 3.2 (Gen. 1) port, and an audio jack.

Disassembly, upgrade options and maintenance

The bottom panel of this notebook is held in place by 13 Phillips-head screws. After you undo them, you need to pry the panel with a plastic tool and lift it away from the chassis.

Our unit is equipped with the larger 90Wh battery pack. It lasts for more than 7 hours of Web browsing, or 6 hours and 30 minutes of video playback. You can remove it, but you first need to undo 5 Phillips-head screws. After that, unplug the connector, and pull the battery from the laptop.

In terms of memory, there are two SODIMM slots that work with DDR4 RAM for a maximum of 64GB in dual-channel mode. Storage-wise, there are two M.2 PCIe x4 slots with Gen 4 drive support.

Looking at the cooling, we see two heat pipes dedicated to the CPU, as well as three more used by the GPU. A sixth heat pipe is used to cool down the VRMs and the graphics memory. However, it is not connected to any of the three heat sinks and two fans.

Display quality

MSI Crosshair 15 (B12Ux) in the configuration we tested has a 165Hz QHD panel – BOE NE156QHM-NY1 (BOE09C2). Its diagonal is 15.6″ (39.62 cm), and the resolution is 2560 х 1440 pixels. The screen ratio is 16:9, and we are looking at a pixel density of – 188 ppi, and a pitch of 0.13 х 0.13 mm. The screen turns into Retina when viewed at distance equal to or greater than 46cm (18″) (from this distance one’s eye stops differentiating the separate pixels, and it is normal for looking at a laptop).

Viewing angles are excellent. We offer images at 45° to evaluate image quality.

Also, a video with locked focus and exposure.

We measured a maximum brightness of 298 nits in the middle of the screen and 278 nits as an average for the whole area, with a maximum deviation of 9%. The Correlated Color Temperature on a white screen is 6450K – slightly warmer than the optimal for the sRGB standard of 6500K.
In the illustration below you can see how the main display performs from a uniformity perspective. In other words, the leakage of light from the light source.

Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work. The contrast ratio is good – 1050:1.

To make sure we are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.

Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people on HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook.

Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.

The yellow dotted line shows MSI Crosshair 15 (B12Ux)’s color gamut coverage.

Its display covers 99.5% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976, and 98% of the DCI-P3 color gamut, resulting in a vibrant and punchy image.

Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.

We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange, etc. You can check out the results in factory condition and also, with the “Design and Gaming” profile.

Below you can compare the scores of MSI Crosshair 15 (B12Ux) with the default settings (left), and with the “Gaming and Web design” profile (right).

We also compare the scores of MSI Crosshair 15 (B12Ux) with the default settings (left), and with the “Gaming and Web design” profile (right) against the P3-D65 color space.

The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light.

The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale, and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle, and the surrounding light conditions.

Response time (Gaming capabilities)

We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa. Display OverDrive On.

We recorded Fall Time + Rise Time = 9 ms.

After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude.

The same graphics with Display OverDrive turned Off.

PWM (Screen flickering)

Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.

MSI Crosshair 15 (B12Ux)’s display doesn’t use PWM to adjust its brightness at any point. This means it is comfortable for long gaming sessions without harming your eyes in this aspect.

Blue light emissions

Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.

Office Work

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

Design and Gaming

This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.


Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

Now, this result is very interesting. The laptop can maintain its 140W power budget, but if you run it without the CoolerBoost function, it will heat up. A lot! In fact, using CoolerBoost lowers the temperature by 12°C. This is huge. And do you know what is even better (or weirder)? The laptop is not too loud even when this function is enabled. Our advice would be – never turn it off, when you’re gaming.

Gaming comfort

Because the results can be clearly seen in the IR image below. The middle part of the keyboard reaches the whopping 60°C. This is a high-enough temperature to sous vide beef. Not cool, MSI… quite literally.


This is weird. We rarely fail to express our impressions of a machine, but today, the Crosshair 15 might have bested us. It is definitely not a bad device. It offers a good amount of performance, and its visual appeal is refreshing, if not else. However, we were baffled by the cooling policy.

You see, if you are an enthusiast, you will find a workaround – either use the CoolerBoost option at all times or just make yourself a proper fan curve, via the MSI Control Center. Most people, on the other hand, prefer to turn their devices on and start playing straight away. The 60+°C we saw on the keyboard is definitely not healthy, and if there is a way to prevent it – it is by increasing the fan speed. We feel that MSI must address this issue themselves, and introduce a more aggressive fan curve through an update as soon as possible.

On the other hand, other aspects of the device are truly great. The battery life is okay for a gaming machine, while the upgrade options are fantastic – two SODIMM slots, working with good ol’ DDR4 memory, as well as two M.2 PCIe x4 slots, which also support Gen 4 drives.

MSI Crosshair 15 (B12Ux)’s IPS panel has a QHD resolution, comfortable viewing angles, and a good contrast ratio. Its backlight doesn’t flicker, while the 165Hz refresh rate is paired with very quick pixel response times, and an option for Overdrive. Furthermore, the panel displays 98% of the DCI-P3 color gamut, and surprisingly, it offers extremely high color accuracy with our Gaming and Web design profile.

In fact, this might be the biggest feature of the device. Because, to be frank, neither the keyboard nor the touchpad is something to write home about. Also, the single USB Type-C port can only be used for data transfer (and charging external devices like your smartphone).

The bottom line here is that we can’t really recommend buying this laptop at the moment, but we would do so if MSI fixes the fan curves on their performance presets.
