Disclosure:  The CM310 optical gaming mouse is loaned by Cooler Master for this review.

Cooler Master has been in peripheral business for a long time, especially with regularly releasing newer keyboards and headsets. The Cooler Master CK550 and the MH751 are two good examples. The gaming peripheral market is over-crowded and yet it manages to sell. The last mouse I’ve reviewed from Cooler Master is the Alcor and the Mizar. I loved the Alcor optical mouse. It was an agile mouse with all the switches places in reachable areas and I wanted more was the grips the Laser mouse Mizar. This wasn’t the only brand that had this point of view at the time since everyone was in the race to push laser sensors and the next best thing. I never really understood why optical sensors were considered less premium to justify lesser premium features when it was hassle-free, compared to laser sensors of certain makes that had quirks that took some firmware and sensor updates implemented by the manufacturer. Logitech was one of the gaming peripheral makers that were able to capitalize this with its MX series. For some reason, it ditched the MX branding under G series- and now brought it back.


This did give other mouse manufacturers a good reputation among gamers and PC enthusiasts. Zowie, Steelseries, Razer, eVGA and several others got a good share. Eventually, HyperX had something. Cooler Master seemed rather conservative when it comes to a mouse. That doesn’t mean they cannot make a good enough mouse. It felt they were holding itself back.

But we have the Cooler Master CM310, now! An optical mouse with the same essence as the CM Storm Alcor….and rubber grips! Excellent. Naturally, there would be changes in design, features and sensors. It does seem to be carrying its spirit.

Packaging and Content

CM310’s packaging is a little overkill for its class and price segment, but hey, why bother complaining about that? It does look good enough to keep as a collector’s item for whatever reason. I’ve purchased the Logitech C922X and for its price, the packaging is no different than that for a pack of cards.

You’ll just get the mouse and the instruction manual. Nothing else. There’s really nothing to accessorize gaming mice, apart from a USB cap and maybe a spare mouse feet? But Cooler Master maxed out whatever they can provide on the mouse, giving it a good 1up over the previous CM mouse I’ve tested- the Alcor!

The Cooler Master CM310 is using the Pixart A3325 sensor, the same optical sensor renamed in the SteelSeries Rival 110 as ‘TrueMove1’ with some on-chip upgrades. The mouse weight 100 grams and has 2 years warranty. There are a total of eight switches for the intended plug-and-play users with matte finish coating and 7 variable DPI switch between 500 to 10,000 DPI.
