Best fan for a gamer to stay cool in a hot office

Best fan for a gamer to stay cool in a hot office
This cooling unit has been a game-changer for my office setup. With a high-end gaming laptop generating heat and the door usually closed, my workspace used to get uncomfortably warm. Fortunately, I found this gem, and now my office stays cool even during intense gaming sessions. I set it to exhaust mode to pull the hot air out, and it fits perfectly in my window. The build quality is impressive, and the performance exceeds my expectations. I can finally enjoy gaming without overheating. The power of this fan has been outstanding in removing all the hot air from my office.

    I’ve been using the Bionaire Thin Window Fan (BWF0502M-WM) for a few weeks now, and I’m very impressed with its performance. It fits perfectly in my window without blocking too much light, thanks to the slim design. Installation was simple and didn’t require any tools—just slide it into place and plug it in.

    The fan has three speed settings and two independent fans that can be set to intake or exhaust manually, which is great for controlling airflow depending on the time of day. I use it mostly at night to pull in cool air, and it keeps my room comfortable without being loud or disruptive. It’s noticeably quieter than other window fans I’ve used in the past.

    One of the best things about this fan is how energy-efficient it is. Instead of running the AC all night, I can use this to cool my space, and it’s made a noticeable difference in my electricity bill.

    If you’re looking for a reliable, no-frills window fan that gets the job done, this is a great option. It’s perfect for bedrooms, offices, or small apartments. Just be aware that it doesn’t come with a remote or digital controls—everything is manual. But for the price and performance, it’s a solid choice!
  • Reviewed in the United States on May 3, 2025
    I purchased this along with a Genesis brand one because A. First time purchasing a window fan so wasn’t sure what to look for, and B. I have 2 windows but absolutely no air flow, from outside or in. My thinking was to have one on output with the other in. Turns out that wasn’t even necessary when using this brand’s. This one may be more money but it is worth it!!
    First thing I noticed was noise level. Bionaire’s is quiet, even on high. It has a nice background white noise effect, that’s all. The other was so loud I had to blast the tv volume up just to hear it.
    Second, it’s much more powerful. When I have it in one window on output it actually pulls in air from the other window and creates a nice breeze. On input it offers nice air flow as well, and will feel cool if near it.
    At first I didn’t think I’d really use the remote, but that actually comes in really handy and I use it often.
    Only downside: when you use the exchange option, you can not choose which fan is pushing air in or out. That would be optimal.
    Overall I highly recommend this product. I’ve not had it long, but I’ve been using it almost non-stop and still like it.

    Pros

    Build/Design -

    1- The extension panels on the sides allow it to fit pretty much all window sizes without the need for additional parts/panels.

    2- The cord length is great and allows it to be plugged into an outlet fairly far away from the window.

    Functionalities -
    1- The ability to blow in or out with the two fan motors independently is a must have.
    2- The temperature sensor control feature can be very nice during the spring and colder summer nights to help cool down your house instead of using an air conditioner…without it causing your room/house to get too cold because it will auto shut off after going below a certain temperature. *This feature can be turned off so you can have it run all of the time if you want to*
    3- It has a remote is also pretty nice to have.

    *Bonus feature - since it has a standard IR remote there are multiple smart home devices/hubs that can replicate the IR signal which means you can easily automate turning on the fan with various criteria being met by other smart home sensor devices (e.g. CO2 sensor, humidity sensor, temperature sensor located somewhere else in your house….etc)

    Air flow -

    1- all air flow settings are pretty powerful and can help with ventilation or air circulation in a room.
    2- Even the low setting is enough to get good ventilation.

    Cons/design improvement ideas:

    1-The extension panels are great but can be a little frustrating at times because the lock mechanism really can’t be easily disengaged while the fan is placed in the window frame which makes it annoying to adjust to the right width if you don’t get it perfect the first time.

    2-It would be nice if there was an add-on mesh panel that came with it that you could remove/attach (in case you had tiny flies in the area you live to keep them out)

    5.0 out of 5 stars Phenomenal Window Fan!
    Reviewed in Canada on July 23, 2018
    This fan is absolutely amazing and I highly recommend it. I've purchased other window fans in the past and none compare. In fact, I will likely buy a second.

    Here's what you'll love:

    THERMOSTAT: This fan has a built in, programmable thermostat which I love. It can be set as cool as 60F. This means you can leave the fan running on a cool night and it will automatically shut itself off once it reaches your selected temperature and you won't end up waking up in the middle of the night freezing cold. The current room temp is shown in red LED lights on the display. Once you press the button to select your desired room temp, it will show your selection and after a few seconds flash back to the room temp which stays on and reflects the current room temp. The lights on the display showing the temp may or may not bother you, depending on how sensitive you are to lighting in your room at night while you try to sleep. Worst case, it's an easy to fix to cover it with something and it hasn't been an issue for me and I love a dark room for sleep.

    FAN SPEEDS: There are three fan speeds, low, medium and high. I keep mine on high just to maximize on air flow. It's a great breeze and strong enough fan to air out a large bedroom or medium sized living space.

    FAN OPTIONS: There are two small fans built into this product. An interesting bonus feature on this fan is that you can choose air in, air out, or air in AND out (exchange). The options basically change the direction of the fans to both spin to blow air in, both spin to suck air out, or one fan blows air in while the second fan sucks air out (to exchange the air in the room). Personally, I prefer the air in feature, especially if you're looking to cool off a room and it's cooler outside.

    DESIGN: This fan fits into my windows perfectly. What I like is that it has two plastic 'flaps' on top that grip the window and hold it in securely. Other window fans I've owned didn't have this, and without the flap, makes it much easier for the fan to fall out or be bumped out of place. This fan stays securely in the window. Equally awesome is that the fan has a built in accordion style slider that easily slides out and fills the open portion of the window. It has two lock buttons that lock the slider into place as well so it doesn't end up moving while securing the fan into the window.

    REMOTE: This fan comes with a remote control. This is handy for when you're laying in bed and want to adjust the temp, turn off or turn on the fan. You can control everything from the remote (as you could on the fan itself).

    QUIET: This fan is extremely quiet. A few times during the day I caught myself walking up to the fan to see if it was on because it was so quiet. Turns out, it was running on high and just super quiet. Still great airflow even with little noise.

    AIR FLOW: Great air flow. Strong breeze into the room and cools off our large master bedroom significantly without issue. These are strong little fans.

    TIP: The fan has a standard/average length cord so make sure the window you plan to place it in has a plug near by. If not, have a short extention cord handy to ensure it reaches the outlet.

    I purchased this fan based on its great amazon ratings which is also why I wanted to give back and write this lengthy detailed review. This review is my own and I didn't receive any perks or freebies for writing it. I'm extremely satisfied with this fan and will likely be buying another one for our house. You will not be disappointed with this fan. You will love it! Five stars!!

    En épocas de calor suelo sufrir bastante en las noches por el calor que hace, he comprado ventiladores de torre y de techo , pero este producto es el mejor hasta el momento, ya que tiene varias funciones para las aspas, una que mete el aire frio de la calle , otra que saca el aire caliente del cuarto , y esa función es la que más me ha servido , de hecho tiene una tercera función y en ella una aspa saca aire y la otra mete el aire.
    Y en estos últimos días que ha hecho mucho calor la verdad no he sufrido como en años anteriores , sin duda lo recomiendo, lo único que me preocupa es que soporte el uso rudo, ya que lo dejo prendido por muchas horas seguidas y se encuentra en la ventana y le pega el sol mucho tiempo.

    5.0 out of 5 stars does a great job of bringing cooler air into the room
    Reviewed in Canada on August 14, 2018
    I have a south/west-facing apartment that gets pretty hot in the summer.. I have a portable air conditioner in the dining room that helps keep the living and kitchen areas cool, but my bedroom stays hot and stagnant, especially when there's no breeze. Which is frustrating when it's actually cooler outside than in. A friend of mine recommended getting a window fan, and after googling showed that this fan is the clear winner in most of the comparisons I read, I decided to give it a try.

    Sadly, it doesn't fit my slider window properly – I have older windows and there's a lip/handle on the slider window that means I can't install this fan as designed, but with a bit of angling, and some foamcore and tape to fill in the gaps, I got it secure and working. Within just an hour or so, my bedroom was cooler than my living room (which never happens).

    Even on the highest setting, the fan is pretty quiet. And even on the low and medium settings, there's good airflow. The controls are easy to use and understand.

    My only complaint about this unit (other than it not fitting in my window, which I won't take points off for), is that the unit I received looked like it had already been opened and returned. I could tell that the plastic bags inside the box had been opened and sloppily re-taped, the manual was crumpled, and one item wasn't even wrapped in plastic. I expected better from Amazon. I'm still giving 5 stars though, because the product itself is good.

    Editing this review to update that I've bought a second unit because I was so happy with the first one. In addition to not quite fitting in my windows, because of the style of window, I also had to remove my screens to get it to fit. To compensate, I bought some heavy duty outdoor-rated velcro, taped it around the edge of the unit, and used that to attach some mosquito netting. Works perfectly.

    4.0 out of 5 stars Vale la pena

    Si vale la pena, cuando hace frio afuera en la noche pero hace calor adentro, ayuda. Hay detallitos, como la temperatura esta en Fahrenheit y como el 95% del mundo no lo entiendo y no se puede cambiar. Tampoco esta claro si esa temperatura es para adentro o afuera entonces no se para que sirva. Pero, los ventiladores funcionan y eso es lo importante.
