Here’s how it works: CoolerBooster is an exhaust fan that fits on the back of your PC housing. A big plus to installation, you don’t have to remove the cover on your PC to install it. By following the easy to follow step-by-step installation instructions, it took me less than 15 minutes to have it plugged in and running — well, I’m a slow reader. The only tool I needed was a slot screw driver. CoolerBooster uses a separate line cord with an in-line rotary switch which plugs into a power strip outlet or a wall outlet so that you can run it independently of your PC being on or off. Run it for 10 minutes after you shut off your PC and not worry about latent heat damage again. The important thing is how it will lower the internal temperature.

The heart of CoolerBooster is a high-efficiency ball bearing, low-friction fan that comes with a warranty for the life of your computer. Pretty impressive, eh?

CoolerBooster lowers the CPU temperature around 5 degrees centigrade (Graph 1). And CoolerBooster lowers the  case temperature about 10 degrees (Graph 2). Even more telling is its affect on latent temperature as depicted line Graph 3 with the system off and CoolerBooster still on.  Latent temperature is virtually eliminated. CoolerBooster actually takes the case temperature below ambient because of the continuous airflow.

Forget the graphs and temperature readings as the best test of all is the feel test. After your system has been on at least an hour, feel the top of your case before using CoolerBooster. If it is warm to the touch it won't be with CoolerBooster. And instead of getting hotter when you turn it off. With CoolerBooster still running your system will immediately begin to cool down.

The unit comes fully assembled. All I had to do was follow the instructions by removing the power supply’s screws one at a time, replacing each one with parts to attach the CoolerBooster.

Any downsides? There are two. At first, I would forget to switch the fan on each day when I started up my PC. This becomes a habit forming thing to remember to switch the fan on each day when I sit down at my desk. The second thing is a slight increase in fan noise as you now have two fans, the power supply fan and CoolerBooster, both operating at the same time. The peace of mind that I’m getting rid of excess heat inside my PC easily warrants a few extra decibels at my desk.

You can buy CoolerBooster on-line . for $39.95 plus 6.95 shipping and handling — or — next time you are driving by Amenity Computer Services on Eckhert Road, save yourself the shipping costs by picking up a unit there.
