Coolermaster Notepal X-Slim Notebook Cooler Review


Many notebook coolers get the job done well, but few of them perform well and then slip easily into your briefcase or notebook-toting backpack.  Coolermaster's X-Slim has a profile that looks like it means business, and stows away seamlessly when on-the-go.


NotePal X-Slim, a lightweight and simple laptop cooling pad for the classic NotePal X family. X-Slim is the ideal companion for 7"~17" laptops. The ultra slim and lightweight design is made for easy carrying and storage, two height settings for ergonomic operation, fully meshed surface plus 160mm silent fan provides excellent cooling performance.


- Classic X design, slim and lightweight for easy charring.
- Silent 160mm fan with great cooling performance.
- Two height settings for the ideal viewing/typing angle.
- Full range metal mesh for superior airflow.
- Cable grooves for easy USB cable management.
- Powered by USB port extender.
- Supports up to 17" laptops.

The X-slim comes in a fittingly low-profile box with images outlying its primary features and all specifications are listed on the back.

The contents of the X-Slim's packaging are minimal, the cooler itself, the USB extender power cable, and a user manual.

Nearly the entire surface is comprised of mesh, promoting excellent airflow throughout the bottom, and especially good cooling without the fan running, and would act great as a passive stand/cooler.

The bottom has a centralized venting system for intake to the center 160mm cooling fan.  The profile of the X-Slim, as would seem obvious given its name, is trimmed wherever possible, minimizing its effective depth, as well as weight.

The side profile is very... low profile.  It can be held, moved, and carried easily, it is very very light overall.  The outer dimensions are "sucked in" everywhere they can get away with it, and other than the fan, it's a hollow shell of the bottom plastic and the upper mesh, which is great from both a weight and airflow standpoint.  There is also some great cable management features brought to the table, with not only routing grooves, but storage rungs and a clip in spot on for the USB connector, and even better, it's mirrored on both sides so you can have it setup to whichever side you prefer for your notebook.  The edge has a smooth and nicely contoured piece which covers the edge of the mesh, and is very comfortable to hold.

Like I mentioned earlier, the overall "airiness" of the cooler would make it a great passive cooler without using the fan at all, and flip-out feet only further this quality.  Not only does it help put your laptop into a more ergonomic position, but helps give added clearance for airflow not only on a desktop, but in particularly soft surfaces, such as a mattress or blanket which could otherwise suffocate your airflow and potentially lead to dangerously high component temperatures.  It's very comfortable to have on your lap, and since it's so light, it's not a burden like many others may be.

Transportation is also great, as it easily slides in next to my notebook in my backpack, and I don't really notice it while carrying it around.  The cable management clips keep everything tidy through travel, and the deployable feet make it easy to slide it in next to your notebook in any bag you carry it in.


The X-Slim definitely does a good job at keeping notebook temps down.  I wasn't able to make it through a full stress test (only the CM Storm SF-19 has been able to achieve that), but, in general, fan speeds were way down, and the surface temperature of the notebook was drastically reduced.  Lower internal fan speeds means longer life for your notebook, and even in a passive mode, fan speeds were also down by a noticeable margin.  The lightweight nature makes using it on your lap a much more pleasant experience (and helps prevent some of the harmful issues known with using a notebook directly on your lap).  The large, 160mm fan is very quiet, and its large size means it can push a large amount of air at lower RPMs, and thus much lower noise levels.  Overall, a light, slim cooler that packs a punch for its size and weight.

It also has enough size that it snuggles in nicely under my HP DV9000 series 17-inch notebooks, as the edges of the squares off "X" extends its profile enough to adequately accommodate a 17-inch laptop without adding a large amount of bulk to it.

Final Thoughts

Overall, the X-Slim strikes a great balance between, size, portability, raw cooling performance, and weight.  It's large enough to comfortably accommodate 17-inch laptops, light and slim enough to ride alongside your notebook wherever you take it without you noticing it's t here, and "airy" enough to work great as a silent passive cooling solution.  It's extendable feet will shift your notebook into a more comfortable position, add cooling clearance, and allow you to use your notebook on soft surfaces without risking overheating.  Built-in cable management with USB stowage makes it convenient to move around, especially if you don't want to use the fan on the cooler.  Overall, probably the best all-around notebook cooler, because of the balance it finds between a wide array of uses from high performance, large 17-inch notebooks to the mobile user.

It really looks thin, the design is okay. But anyway Im looking for effective and silent one and it has it here. SO this is thumbs up plus its lightweight.
