75mm x 30mm 7530 12V DC Brushless Cooling Blower Fan, Dual Ball Bearing System, 2pin

It's a quiet-ish fan that shifts quite a lot of air for its size. If you can wait the few weeks it takes you can get it cheaper from china. I wanted to solve a hot air pocket problem with my graphics card and paid for this one as it was in stock. Being a blower design ducting the air away was relatively easy. In combination with a temperature switch this has worked out well.

I'm using these to blow air out above a radiator. Works well and not noisy.

I have found this 70 mm x 30 mm fan has a good airflow and pressure considering its size. But it is only just there for my project. On its own its is almost silent. But when fixed to a case it makes a wining noise, but not a loud one. Only time will tell about its reliability. It looks well made with a balanced fan. Its good for cooling 3d printer nozzles, or computer processors. Not so good with volumes of air like the normal computer fan, but has the ability to force the air. In to a case unlike normal computer fans. I found it to be ok for what I used it for. Good product.

Very powerful blower although bit noisy (I guess it comes with the power thing) and does not work when trying to control speed using PWM.

Brilliant radial fan for use as a part cooler on Ender 3D printer. Plenty of designs on Thingyverse to house this fan. Provides an excellent flow of air which is concentrated at the outlet duct

I bought this product to replace a broken 3D printer fan. I’ve attempted to fit it but the quality is terrible. The outlet dimensions are way off so I’ve had to file it down to fit my duct.It only has one choice of cable route at the back also so it doesn’t fit my usual mount plate.On top of that it comes with a short power cable.At >£10 for 1 fan I was expecting a better product than the £2 versions from eBay but I didn’t get it.Update: I’ve just tested it, it’s not a variable speed, will only work at 100%

This was used to replace a fan in a US made bbq guru temperature control device.It worked perfectly. Would buy again.

Hooked this up to my bbq & it’s great,, boos really well & makes my coals hot!
