OPOLAR LC-06 Laptop Fan Cooler review: Funky and effective
June 01, 2025
Most laptop coolers operate on a similar premise. You place your laptop on top and fans drive cool air into the intake vents. The cool air helps keep things under control and prevents overheating. OPOLAR, however, takes a different approach. Its laptop cooler product doesn’t shoot air into your machine. Instead, it draws air out of mostlaptops. The OPOLAR LC-06 Laptop Fan Cooler has a funky design and some neat features, but does it actually work? Let’s find out.

What is the OPOLAR LC-06 Laptop Fan Cooler?
The device is fairly small and fits in the palm of a large hand. The front has a spot to attach the soft silicon piece that eventually makes the seal around your laptop. Around the back is the output vent. The top of the device features an on/off button and two buttons to increase or decrease the fan power. We don’t know the size of the fans, but they run at 2,600 RPM at the lowest setting and 5,000 RPM at the highest.
You can attach the device to your laptop by one of two methods. The first is a detachable plastic lip with little suction cups. It temporarily attaches the cooler to your laptop while also seating it to your desk so it doesn’t move. The second method uses M3 tape to permanently attach the cooler to your laptop. We only recommend the permanent installation method once you confirm this product works for you.
Finally, OPOLAR LC-06 also comes with a display. It shows the temperature of the air being pulled through the cooler. you’re able to long-press the power button once the device is on to switch between Fahrenheit and Celsius. You can also use the display to make sure the device is actually pulling the warm air out of your laptop.
How to set up and use the OPOLAR LC-06 Laptop Fan Cooler
The device attaches to your laptop via USB. There is no USB pass-through, but the cable is detachable so you may replace it if it breaks. You’ll need a Micro USB to USB Type-A cable if you want to replace it. Once your laptop is on, the device starts automatically. You can then long-press the power button to set Fahrenheit or Celsius and the other two buttons to increase or decrease the fan power. The fans have 13 levels of power, more than virtually any other laptop cooler.

The installation method has a few issues, however. For starters, many laptops have multiple output vents, especially gaming laptops. Usually, there is one for the CPU and one for the GPU at a minimum. You may need to Google Search for information about your laptop to know which vent is the one you need. We have also seen people buy multiple OPOLAR LC-06 devices to attach to both output vents for even more effective cooling. Those setups tend to look ridiculous, but they do work.
On the plus side, the unique installation method doesn’t have a size limitation. You can attach this thing to a 13-inch laptop or a 19-inch laptop and not have to worry about overhang, extra space, or other size issues.
How well does the OPOLAR Laptop Fan Cooler perform?
We ran a total of four tests with the OPOLAR LC-06:
All tests were conducted with the laptop set to Windows Balanced power settings with no modifications. The cooler was set to its highest possible settings for the best possible cooling numbers. The temperatures were recorded and double-checked with HWMonitor, ASUS Armoury Crate, and Intel XTU.
Without further delay, here are the results of the tests.
The OPOLAR LC-06 did a surprisingly decent job. I had it attached to the CPU vent (with the temporary install method) so the GPU temperatures didn’t change all that much. The biggest gains were during intense activities, including a 5C swing during stress testing and a 3C swing during gaming. I actually played a second game of Halo Wars 2 with the cooler attached to the GPU vent and saw an impressive 6C swing in the GPU temps when accounting for spikes.
It doesn’t seem like a lot but there is more to unpack. During the CPU test, the laptop didn’t register a thermal throttle at all with the cooler. Additionally, when it power throttled, the clock speed remained 0.4-0.5Ghz higher while still maintaining a 5C lower temperature versus without a cooler. The test results conclusively show that the OPOLAR cooler actually works. However, for maximum benefits, I would’ve needed a second one to vent out the CPU and GPU at the same time.

Is the OPOLAR LC-06 Laptop Fan Cooler good?
The difficult part is making sure it actually fits your laptop, your desk, and your lifestyle. After that, it’s a matter of setting it up to your tastes. We recommend people who travel a lot restrict their installations to the temporary method so they can remove it from the laptop and place it in a bag. It’s virtually impossible not to break it otherwise.

The only other potential caveat is that the OPOLAR LC-06 pulls air out from the vents by force. Your vents connect directly to your CPU and GPU fans. There is a small risk that the cooler puts undue stress on your existing laptop cooling fans and causes early failure. Otherwise, this is a really neat little product that does actually work.
Finally, OPOLAR actually has a slightly cheaper (and older) version of thison Amazon for $24.99. The only real difference is the lack of a lit-up display. It’s honestly not worth the difference in price to go with the older version. If you go with this type of cooler, spend the $29.99 (prices may vary) on the latest version with the display.
