In the summer, most people turn on air conditioners to keep everything in their house cool. Now you can give your computer the same treatment with Waffer’s PC AirCon PAC 400. I was thrilled when I thought about how much cooler my case and components could get. Could air conditioning be the next big thing for us enthusiasts? Let’s dig in and find out how much of an impact a PC air conditioner truly makes.

Waffer has been serving different markets in the technology industry for more than 50 years. Recently, it has been among the best in magnesium alloy injection molding. Its thermal division, who manufacture this air conditioner, continues to create some of the best cooling solutions for computer enthusiasts and strive to be a leader in the PC cooling market.

Closer Look:

To be honest with you, I was completely clueless on what this product would look like, how big it was going to be, and how it worked.  When I saw the box that the PC AirCon PAC 400 came in, its size reminded me of a size 13 shoebox. I also didn’t have a clue about where the object presented to me was going to go. Inside the case? In a drive bay? I couldn’t wait to find out.


The box took me about two minutes to open without ripping any of the cardboard because it was so intricately folded to allow the product to be visible. Ah hah! It does go in a 5.25” bay! The unit is almost 10 inches long, so I can already tell it will stick pretty far out of the case. Once you get the unit out of the box, looking closely at the top, you’ll see that it’s a clear fan (with blue LEDs) with a heatsink under it. Also notice the LCD panel which displays the temperature in Celsius.


The bottom of the unit has a black fan that sucks air into the air conditioner. On the side, you can see a switch which has 3 available settings: off, fan, and snow. In the “Fan” setting, the blue LED fan on top does not spin, only the bottom black fan does.  In “Snow”, both fans spin and work as described above.


The PC AirCon PAC 400 has a very unique power connector that I have never seen before. It is one inch wide and a half an inch tall.

Closer Look:

You may have noticed the shaft to the right of the power connector. This is where I figured out how the unit works. The top clear fan sucks air down onto the heatsink, which cools it, and then the black fan on the bottom blows the air down this shaft and into your case. If you look closely, you’ll see the heat sensor that relays the temperature to the LCD panel on the front.  The shaft’s opening is 2 ¼” inches long and 1 1/8” inches tall, so it’s not very big.

Now that we’ve covered the unit, let’s examine the accessories. The PC AirCon PAC 400 comes with the mounting bay which fits into your 5.25” bay, instruction manual, and screws to secure the mounting bay to your case.

The mounting bay has a plastic door which folds down when you push the air conditioner into it. It also has a built-in key on the side so that the user can lock the air conditioner into the bay or unlock it to take it out. When you fold down the door, you can see the female power connector which has a built in adapter to convert it to a 4-pin power connector.


On the side of the mounting bay, you’ll notice the holes for the user to use in order to secure the bay into a free 5.25” slot.


The first thing you must do is screw the mounting bay into an open 5.25” slot in your case. After this is done, slide the PC AirCon PAC 400 into the mounting bay and push firmly to ensure that the power connectors are making complete contact. Below is a picture of the air conditioner attached into the mounting bay. To ensure the air conditioner is in all the way, try locking the key. If it turns 90 degrees, then the air conditioner is correctly inserted.

The last thing you must do is attach the 4-pin molex power socket to a free 4-pin molex plug from your power supply.


As mentioned earlier, there are 3 settings the user is given with the air conditioner: “Off”, “Fan”, and “Snow”.  “Fan” is when only the bottom black fan is blowing air and the top blue LED fan is not active.  “Snow” is the air conditioning; both fans are active in this setting.

Test System:


All of my tests were conducted in my basement, which has a pretty consistent temperature of 14C. I’m testing this air conditioner in Enermax’s Uber Chakra full tower case (OCC Review) and my old SilverStone TJ-06 full tower case. I tested CPU, motherboard, and case temperature under idle and load conditions. I took all of the results from the “Snow” setting because I didn’t get very notable results with just the “Fan” setting on. Lower is better in all tests.

 You might be wondering why the case temperatures are so different. The Enermax case has a 250mm fan blowing right onto the CPU and motherboard, so that had some effect. Also, in the SilverStone case, the hard drive rack is vertical and is fairly close to the bay devices, so the cold air would be blowing directly onto the steel hard drive cage and then going down into the case.  I was not the least bit surprised about the differences of temperature in these cases for that reason.

It is very clear that the air conditioner did slightly help cool down the case, CPU, and motherboard in two different instances. During testing, I was almost driven mad by the noise that this unit was making. It was ridiculously loud! Even the “Fan” setting was too loud for me.


After testing this air conditioner in two different cases, I definitely saw things that I liked and things that I didn’t like. I did like how this product had a simple design and worked as described. The temperatures that were derived from this unit weren’t too great but they did cool down the system. The switches on the unit were also a plus because it gives the user customization of what’s going into their case. However, I was disappointed how far this case stuck out of both cases because it was getting in the way of passer-bys. I was mostly disappointed by how loud the air conditioner was on the “Snow” setting. I was on the verge of having to go get some ear plugs while I tested this unit. It’s a great idea and an even better start on the road to optimal cooling via air conditioning.
