The Coolermaster Gemini II M4 is a super low profile CPU cooler. This tiny unit is a great product for anyone looking to build themselves a HTCP system. When it comes to CPU coolers in the industry, we see some extreme and radical designs with large dual fans and even sometimes quad fan cooling, built onto a massive array of fins with plastic here there and everywhere. Those coolers are great for the heavy gamer, however not everyone wants something that big and expensive inside their lower end systems. If you are one of those users then you will want to take a look at the Coolermaster Gemini II M4 CPU cooler that we have here for you today...
