My computer desk gets hot enough to fry an egg during the summer. I tried propping the side panel open, but that just let a ton of dust inside my PC case.
I finally grabbed this cheap USB fan from AliExpress to see if it could help. This 40MM 50MM 60MM 70MM 80MM 90MM 120MM Cooling Fan Brushless Motor Case Fan Quiet Fan With USB Cable review covers whether these little things actually do anything useful.
What is this cooling fan?
This is a simple, no-frills fan that plugs directly into a USB port. You can pick almost any size you need, which is great if you have a tight space or a weird project.
The best part is that it is incredibly budget-friendly. I paid just a few dollars, and since I found a seller offering free shipping, it showed up in my mailbox without any extra fees.
Why choose these fans?
Most people buy these to cool down electronics like routers, external hard drives, or home theater gear. I used the 120mm version to push air through a cabinet where I keep my game console.
The USB cable is a huge convenience because you do not need to mess with power bricks or wall outlets. You can just plug it into the back of your TV or your computer tower.
The brushless motor is the secret to why they stay quiet. I leave mine running all night while I sleep, and it sounds like a very soft hum rather than a buzzing vacuum cleaner.
Honest pros and cons
Buying gear from overseas always has a few trade-offs. Here is what I found after testing them for a few months.
- Pros
- Extremely cheap compared to brand-name PC fans.
- Wide variety of sizes means you can find a fit for almost any gap.
- USB power makes them very easy to set up.
- Very quiet operation for basic cooling tasks.
- Cons
- Shipping takes forever because it comes directly from overseas.
- There is no local warranty if the motor dies after a month.
- Customer support is basically non-existent if you have a question.
- The plastic feels a bit thin and brittle compared to premium fans.
Who should buy these?
If you are a DIY enthusiast or you just want to cool down a hot router, these are perfect. They are great for people on a budget who do not want to spend twenty dollars on a fancy fan from a big store.
You should skip these if you need a high-performance fan for a gaming computer or a mission-critical server. If you need something that is guaranteed to last for five years, buy a name-brand part from a local shop instead.
What other buyers say
I spent some time reading through reviews from other people who bought this 40MM 50MM 60MM 70MM 80MM 90MM 120MM Cooling Fan Brushless Motor Case Fan Quiet Fan With USB Cable. Most people agree with my experience.
One user mentioned they used four of these to cool a DIY grow box, and they were happy because the price was so low. Another person noted that the shipping took about three weeks, but they felt it was fine because they were not in a rush.
Final verdict
Is this product worth your time and money? If you need a cheap way to move some air around your desk or your electronics, yes.
Do not expect industrial-grade cooling or a lifetime warranty. You get exactly what you pay for, which is a simple, quiet, and effective fan that works as soon as you plug it in.
Just be prepared to wait a few weeks for the package to arrive at your door. If you can handle the wait, it is a solid purchase.
