MSI's transparent TwinFrozr cooler has been pictured.
The cooler looks like it'll feature the same basic design as the TwinFrozr IV cooler, but in addition, it will be transparent. Perhaps we'll see some built-in LEDs that light up the whole graphics card, though there was no indication of that.
In the provided image, you can also see that the cooler is taller than the standard TwinFrozr IV cooler, so this design is likely based on the longer and taller SKU.
We have no idea what graphics card(s) the transparent TwinFrozr will be featured on, though it's possible that it will show up on the Radeon R9-290 card, since we're expecting manufacturers to release their custom variants not long from now.
