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

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

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.

This is an excellent cooler for the Raspberry Pi, even an overclocked Pi 4. The pre-applied thermal tape lost adhesion and was useless. While a second and much thicker piece of thermal tape is included in the box, thicker tape usually doesn't cool as well (and it increase height when applied). I have a good roll of thermal tape, so I was able to use my own. Overall, this is an excellent cooling solution for a Raspberry Pi, as long as you're willing to supply your own thermal tape.

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’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!

This is a well made solid aluminum heat sink for the Raspberry Pi. It looks and works well.One thing to note, if you want to use this with a Raspberry Pi alternative like the ASUS Tinker Board, you may find you need a copper shim for the CPU to get proper clearance for all components. The easiest way to accomplish this is to buy a 15mm copper square (1.5 to 2 mm thick) and place it on the CPU before installing this heat sink.

Original 3-star review:I have a Pi3B+ which is installed in a location where there is limited air flow, and gets quite warm, so I was looking for a good fan/heatsink solution which would help keep the Pi cooler than a typical heatsink/fan solution. This looked like a good option.Unfortunately, the heatsink is a poor fit.Due to the new POE headers on the Pi3B+ motherboard, you have to shift the heatsink towards the DSI display port connector, rather than adhering the heatsink to the broadcom CPU and USB chip, as you do with the Pi 3B motherboard.However, the height of the wireless lan chip (the rectangular chip with the Raspberry Pi embossed on it) is taller than the Broadcom CPU. This means you cannot adhere the heatsink to the broadcom CPU when it is adhered to the wireless chip.One solution is to attempt to "build up" the CPU to equal the height of the wireless chip. As others have pointed out, you cannot use the alleged "thermal tape" for this because it is not really thermal tape. Instead, you have to use a couple of copper heatsinks stacked on top of one another to make the top of the CPU level with the top of the wireless chip. Once you do this, you can use "real" thermal tape to adhere the heatsink to both -- even then, it will be slightly off, but not as bad.Good idea, but poor execution.Unless you have a couple of spare copper heatsinks laying around, opt for a different product here.After some additional testing once I install my unit, I will update this review with some performance data.UPDATE:Well, the unit did help keep my Pi Cooler... but after 45 days, the both fans on the heatsink crapped out and no longer spin.Cannot recommend this product. Downgrading review to 1 star.
