GeeekPi Fan for Raspberry Pi - 30x30x7mm DC 5V Brushless CPU Cooling Fan with 7PCS Heatsink for Pi 4 Model B, 3B+, 3 & Retroflag NESPI CASE Plus (1-Pack)

These run 24/7 on my Raspberry Pi setup as a Pihole for my home network. They are completely silent when plugged into 3.3V. Heatsink combined with the fan (which I ziptied onto the board) lets the board sit at about 40C (104F) in operation (room temp is about 23.8C / 75 F)

Simple and quiet fan. I had the passive copper heatsink installed that came with my original RPi 3B+ kit and running nothing but pi-hole had temps stable around 65-68C. The kit being reviewed comes with several aluminum heatsinks of varying sizes. I didn't change the copper sink on the CPU but added heatsinks for some of the other chips on the board and positioned the fan over the CPU (my RPi case has a riser for mounting a fan. This kit comes with some mounting screws but there are no screw holes on the RPi 3B+ board itself, so you may need to mod your case in some way to mount the fan). Running at 5V and it's silent, and my temps have dropped to 44C.

This was cheap and worked for what I needed it for!

Every time the Pi starts up, the fan sounds like a blender.

This product works excellently with a Raspberry Pi 4 in both the RetroFlag NESPI and RetroFlag PiStation (PlayStation clone). Two larger heat sinks are fairly easy to install. Two smaller heat sinks are best installed with tweezers/pliers to align them properly in the tight spot. Drops temp 30F/16F.

I'd like to echo some comments around here, the fan can be noisy. The caveat is, it's noisy when plugged into the 5v pins. When on the 3.3v it is much quieter. I don't have hard data on the impacts of reduced RPMs, but so far it has been fine for my headless little plex server.Secondly, people talk about the size. I don't know anything about any case other than my own, so I'll say: it fit my case perfectly. That case being the one included with the Canakit. Didn't even need the screws and bolts, as it clicks right into there. I added some rubber O rings I had laying around just to dampen the sound a little more, but I'd wager they did approximately nothing.So yeah. 5 stars, it is exactly what it is. Don't expect a miracle for 6 bucks and you will be pleasantly surprised.

I bought it just to get the heat sinks. My case already had a fan. They were exactly what I needed.

These fans work fine for cases looking for this size. However, they are fairly noisy. I'm not sure how long the bearings on these will hold up before the fan freezes. Should be OK for us hobbyists, but for a commercial or industrial application a fan with proper bearings might be a better idea. For the money and my use case, I can't complain.

I bought GeeekPi Raspberry Pi 4 Quiet Fan to replace my existing fan that's been getting progressively louder recently.Installation was easy and the fan fit perfectly. I am running it at lower voltage and it is completely quiet. I wish that there was an option to buy this fan without any heat sink parts as they were not needed.

I purchased the Retroflag PiStation and it didn't come with a fan. I found this fan for a terrific price and it fit the PiStation perfectly. The RPI4 gets very warm in this case and definitely requires a fan. The extra heat sinks were a big bonus as I also needed them for a new RPI4 that I purchased for the case. Very happy with the quality and price - and no, the fan does NOT run too loudly, it is absolutely acceptable. Highly recommended, good quality and price!

Have the CanaKit Pi 4 case. Original fan got noisy (buzzy), I think the bearing wore out (is there one?). Bought this GeeekPi fan. Replaced the old fan. Fan is now quiet. Problem solved at a fair price.

Very inexpensive and does the job perfectly! My Raspberry Pi 4 was around 50°c without fans, dropped to 35° using heatsinks and fan.

great item, its quiet, works with my Pi 4, no issues at all.
