Cooler Master Reaper Testing & Results

Testing Methodology

The Cooler Master Reaper was tested over a period exceeding 80 hours. The main programs and games used during testing consisted of Adobe CS5, Warframe, and StarCraft II.

Test System

  • Motherboard: Asus P8Z77-M
  • Processor: Intel i5 3570K Ivy Bridge @ 4.0 GHz
  • System Memory: Corsair Vengeance 16GB (8x2GB) DDR3 1600 MHz
  • Video: Gigabyte Windforce GTX 670 TI (2GB)
  • Audio: HT Omega Claro Plus
  • PSU: Cooler Master Silent Pro M700 (Gold)
  • Monitor: LG 27EA83-D 27″ 5ms IPS @ 2560 x1440
  • Operating System: Windows 7 (64 bit)


The Reaper has the ability to change the polling rates individually per each of the four main DPI settings (the maximum polling rate of 1000 Hz was used for all tests). According to two separate polling tools, Direct Input Mouse Rate for DirectX and Mouse Rate Checker, the Reaper actually exceeded the peak advertised polling rate.


Desktop Applications: The Reaper excelled easily and comfortably in this area.  With a native desktop resolution of 2560×1440 the DPI setting mostly used was 5000 DPI. In Photoshop when doing fine detail work such as airbrushing (zoomed up to pixel level), the clutch came in very handy to instantly drop the DPI down to 2000. As for tracking (due to the larger surface pads on the bottom) it did seem to catch hairs and dust particles more easily, so keeping an ultra-clean mouse pad is very important.

Gaming: StarCraft II was used for the mouse button torture test. Even though not specified, it certainly feels like Omron switches were used on all buttons excluding the mouse wheel itself. Playing SC2 seemed a smoother experience with a positive tactile feedback due to the sensitive Omron switches. Warframe was chosen especially to test DPI sensitivity and put the clutch to the test. In Warframe, the weapons load out all have variable levels of zoom. When zooming way out there with any scoped weapon (or bow) the DPI just goes insane-sensitive to the point where it is almost impossible to keep a steady aim. It is a pleasure to report the Reaper’s clutch not only worked beyond expectations, but made an already exceptional game even more fun to play.
