A couple of weeks ago, I reviewed the Asetek WaterChill cooling kit. This water-cooling kit contained both CPU cooling, GPU cooling and chipset cooling, and as far as I could see, there wasn’t anything missing. Asetek, however, found one more piece in your computer to cool, and today I am reviewing the Asetek HD Cooler. Yes, you read right. Asetek has released a cooling block for hard drives, allowing you to lower the temperature of your hot running drives.
