I recently upgraded my system, bumped up the RAM to 32GB with a multi-core processor so I can run many virtual machines. An obvious question would be why do I need all those VMs? I cover Linux and need to be running multiple distros to keep an eye on their development.

It’s very hard, and at times physically impossible to run all those OSes on separate physical machines. The management become complicated and it wastes energy and generates heat. That’s where VMs come handy. You can run multiple systems from the same OS and it’s energy efficient and easy management.

However, as I boot into my distros the fans of my system start grinding their teeth in anger as they try to keep my CPU’s temperature low. I have heard a lot about water cooling, but never tried it before; actually never needed one until now.

However, since it’s my first water cooling I didn’t want to go crazy and put too much money where my mouth wasn’t.

So after investing some time in research I picked “Corsair Hydro Series Extreme Performance Liquid CPU Cooler H80i“.

The box was bigger than I expected but the whole toy was not. It was extremely easy to install; albeit a bit tricky. You have to ensure that both fans are attached properly for inward airflow. One tricky part is connecting fans to the cooler header. The Y cables that come out of the cooler have safety caps on then so it appears that the connectors are incompatible; just pull the caps off and you will see the cables.


Once installed successfully the temperature went down significantly. It was as quite as a pin drop silent room. The fan kicks in only when the system start and then go in pure silent mode. Since I am running Linux I don’t have access to their monitoring software, but I didn’t need it. The fans are absolutely silent even under heavy load when I am trans-coding huge movie files while simultaneously running five virtual machines.

If your Linux box needs some temperature control this is the water cooler I would recommend. At $89, it’s not a bad deal. You can order Corsair Hydro Series Extreme Performance Liquid CPU Cooler H80i from Amazon.com
