iUniker Raspberry Pi 4 Fan, Dual Fan with Heatsink, 25mm x 8cm, 5V, 7500rpm, 37dBA, Fits Pi 4B, 3B+, Pi 2B

Works exactly as it should and allowed some of my Nintendo 64 games to run without issue. Before the fan it was very laggy and locked up several times. Its quite, stayed where i put it, and installation took a matter of seconds. Worth the money.

works like its suppose to, I had that tiny heatsink it comes with when you buy a pi 3 B+ pack and it works fine for 8bit games but when gaming with PS1, N64 and Dreamcast it starts to get hot and throttle the speed down to 1Ghz and goes slow. BUT! with this big heatsink you notice it keeping cool and the 3D games now run much smoother with better frame rate and doesn't throttle down the speed and stays at the 1.4Ghz since the processor keeps much cooler now. well worth it if you going to run emulators/retropies with it

I love this, and it was easy to install. The only problem is that one of my fans do not spin after install. I just installed it according to the instructions. One of my fans did not come on. I watched YouTube, and saw how they installed it, and worked like a charm. Mine does too, with only one fan. Maybe I just got a bad heat sink. This was just 30 minutes after it was shipped to my house. EDIT: After receiving the replacement, it seems like both fans spin great. On my 1st heatsink, only 1 fan was working, and now, both are working with the replacement heatsink I received. Thank you so much for your service. EDIT: After they helped me, they solved my issue, and for this, I upped my 2 stars to 5 stars. Thank you so much.

As you can see from picture, I'm using this on a Raspberry Pi 3B+ inside a case attached to a 3D printer inside an enclosure. Temps inside the enclosure can reach 40C thus prompting the purchase of a low profile fan for the Pi. Two things. 1.) The power dupont connector used for power sits up too high. Power pins should be flush with the highest point of the Pi. 2.) The screws on the fans are not fully counter-sunk into fan housing and stick up enough to prevent my case from fully seating. I was able to do a quick cut-out to make room. But I was hoping to enclose this fully inside the Pi case.

I’m running a 5 card Bramble of Raspberry Pi 4 model Bs the fans keep the cluster cool during operation and are very quiet! I love them for the deal I got on them! If you have RPi 3; you’re in luck! They’ll work for your 3 model B as well! If you’re crazy about Raspberry Pi’s like I am- you need this!

The fan itself and the heat sink work great. My pi4 never got hot enough for the thermal throttling to kick in. The fan is as quiet as other fans this size and not a problem. The fatal flaw is the thermal tape: it’s too weak to hold the weight of the fan. Without extra support holding the fan, it unsticks from the heat and slight vibrations within minutes. I’m not sure stronger tape would help either due to the weight of the fan being too much for any tape I’ve seen. I may glue a screw hole to either side to attach to the pi, but for now it has been replaced by my other case with fan built in.

I've just installed the unit. normally my pi3 B+ reaches 48 to 50 C 806 | 50.5 | 2020-06-15 18:50:02 | | 807 | 50.5 | 2020-06-15 18:55:02 | | 808 | 51.5 | 2020-06-15 19:00:02 | | 809 | 50.5 | 2020-06-15 19:05:02 | | 810 | 50.5 | 2020-06-15 19:10:02 | | 811 | 49.4 | 2020-06-15 19:15:03 | | 812 | 49.4 | 2020-06-15 19:20:02 | | 813 | 49.9 | 2020-06-15 19:25:02 | | 814 | 50.5 | 2020-06-15 19:30:02 | | 815 | 50.5 | 2020-06-15 19:35:02 | after installing the fan, the heat dropped to 32 & 33 C Degrees, | 826 | 33.2 | 2020-06-15 20:55:02 | | 827 | 33.2 | 2020-06-15 21:00:02 | | 828 | 32.7 | 2020-06-15 21:05:02 | | 829 | 32.2 | 2020-06-15 21:10:02 | | 830 | 32.2 | 2020-06-15 21:15:02 | +-----+------+---------------------+ will buy more of course.

This dual fan's is amazingly silent and get the job done. My Raspberry Pi 3B+ stays pretty stable at 44 celsius when I watch movies or stream from it. The first one I got had one of fan's that started to make a lot of noise and just got worse and worse. so I contacted support and they sent me a new one right away no questions asked. So I highly recommend the seller and this product. Nothing negative to say at all except that the wifi case is higher that than the cpu so it won't be flat on the cpu
