My PC was getting hot enough to fry an egg, and the fans were sounding like a jet engine taking off. I did not want to spend half my paycheck on high-end cooling gear, so I scrolled through AliExpress looking for something cheap. That is when I found the Manmu 120mm Rainbow RGB fan.
This Manmu Fetival Pormotion 120mm Computer Fan Rainbow RGB/ High Cooling Performance Gaming PC Fan review is my honest take on whether this budget-friendly part actually keeps things chill. I bought a set of three to replace my stock fans and tested them for about a month.
What is this budget fan?
This is a standard 120mm case fan designed for people who want their PC to look cool without paying a premium. It uses a rainbow LED pattern that shifts colors while it spins, which adds a nice glow to any gaming build.
The main draw here is the price point. You can often find these with free shipping, which is great when you are trying to keep a build under a specific budget.
Features that actually matter
The biggest benefit is the noise level. These fans are much quieter than the basic ones that came with my case. Since I work and play at the same desk, having a quiet machine makes a huge difference in my daily focus.
Installation is simple enough for anyone who has opened a PC case before. The wires are long enough to reach across most standard cases, and they plug into the power supply or motherboard without much fuss.
The rainbow lighting is bright and fills the case well. While you cannot change the colors or patterns, they look clean and modern. The airflow is decent for general gaming, keeping the internal temperatures within a safe range during long sessions.
Honest pros and cons
These fans are not perfect, but they do the job for the price. Here is what you should expect if you decide to buy them.
- Pros
- Very low cost for a set of fans
- Quiet operation even at higher speeds
- Bright, consistent rainbow lighting
- Easy to mount with standard screws
- Free shipping options are common
- Cons
- Shipping can take several weeks from overseas
- No software control for the lights
- Plastic feels a bit thin compared to premium brands
- No local warranty if one stops working
- Mounting screws can strip if you turn them too hard
Who should buy this?
If you are a student or someone building a first PC on a tight budget, these are a solid pick. They give you the look of a expensive gaming rig without the hefty price tag. You get enough cooling power for a mid-range system that does not have high-end parts pumping out massive amounts of heat.
You should probably skip these if you are building a professional workstation or a high-end overclocked PC. If you need silent fans that last for years or you want specific colors to match a theme, look at higher-end brands instead. These are meant for casual users, not power users.
What buyers are saying
I talked to a few others who bought these to see if my experience was just luck. One buyer mentioned that his fans arrived in two weeks, which he thought was pretty fast for an international order. He liked that he could plug them in and have them running in five minutes.
Another user noted that the light intensity is great for a dark room. She did mention that if you are looking for total silence, you might hear a faint hum when the PC is doing heavy tasks. Most people seem to agree that for the price, you really cannot complain about the performance.
Final verdict
My experience with the Manmu 120mm fan has been positive overall. It did exactly what I needed it to do by lowering my case temperatures and making my room look a bit more like a gaming setup.
Just keep in mind that you are buying a budget part. Do not expect the same quality as a fifty-dollar fan from a big-name manufacturer. If you are okay with waiting for shipping and want a cheap way to spruce up your case, these are a great deal.
