Review: makes a good domestic heating radiator fan too - I was experimenting with tiny laptop fans as the premium priced air source heat pump (lower temp) radiator brands use similar to accelerate their heating emittance power - but they are fiddly to add to an existing radiator. Then I spotted this larger 5V fan and have installed it easily, running quietly at low rpm, probably under 1W usage... and it works well to boost the heat in a cold kitchen. A very simple, cheap and easy to fit solution for radiators that are slightly underpowered.
Review: Nice, quiet and effective! - I am using this to help cool a Linear Power Supply. Rather than the fan extract the heat more rapidly I removed the grill and turned it upside down to blow cool air into the power supply. Even on the low setting it has performed exactly as I needed it to. I didn’t want to freeze the LPS just bring the heat down a few degrees. The 40mm size is perfect for the Sengterbelle 12v LPS leaving enough venting either side of the fan for the air to escape. I would like to know how long I can leave this fan on for but there is no info on a constant run so it looks like trial and error but in the meantime the heat is under control even without going high on the setting, works just fine on low. Some say this fan is noisy but seriously I am not sure what they maybe using it for but I have had louder mosquitoes in my ears than this fan! It’s quiet.

### ⭐⭐⭐⭐ Functional, does the job
*by N***R on 2 September 2025*

Sounds a little like a PS2 starting up at high but does the job Doesn't push the most air but does the job, good to keep my laptop cooler and less noisy when gaming or using ai. Seems like it could be good for circulating air in a TV unit with modern consoles or PC also
