GeeekPi Fan for Raspberry Pi 4, Ultra Thin ICE Tower Cooler for Raspberry Pi, PWM Cooling Fan with Aluminum Heatsink for Raspberry Pi 4 Model B Only

Works great, getting the heat pads installed at the proper height so that the heat sink makes contact with all four pads is a little wonky but once you do that, the cooler keeps the pi4 nice and cool

Highly recommend! My pi 4 is used to run a single instance of klipper in a diy printer enclosure made out of wood. It gets pretty hot in the enclosure and having this brought the run temps from a consistent 65 - 75 c down to 40 c no matter how long the 3d printer had been running. If you need a quality cooling solution the works, buy this. Just wish there was a full case option for it.

Dude this thing is overkill but I love it. Their RGB option is a must have for cool points. The cooler works wonderfully under any load! I purchased this for my Pi that stays in my 90-100 degree garage all year long and with this cooler my Pi temperature stays within 10-15 degrees of the ambient air temperature under a light. I ended up buying multiple for any of my Pis that I could fit one on!

As far as performance, this heatsink and fan combo works well! Really well. It takes quite a bit of effort to push the pi4 hot enough to trigger the fan at the minimum setting allowed to trigger it (60C). So it's usually very quiet due to not actually running. But when the fan runs, it's still whisper quiet.The fan didn't run very long once it did kick on, bringing it down by about 12C before cutting off again.Stopping the load, with just passive cooling, the core temp came down to around 40C. Fully idle, it runs around 30C.My only complaint is this is designed only to be mounted using screws from the bottom. The fan bracket has threaded posts for this reason. Which means trying to mount from the top meant threading through there and hoping you have the right pressure. But that doesn't matter because the included screws are not long enough to screw down into something from the top anyway. I was able to work around this by drilling out those threads and buying longer M2.5 screws. This is a requirement if you're mounting this, say, on the back of a display.I can't knock it too much for this problem. This is literally designed to go on a DIY system, so having to DIY the install should just be part of the expectation. It still installs and fits very easily. The fact the fan brought the temp down so fast tells me heat transfer through the included pads is probably perfectly fine.

Out of all of the cooling options I have ever had on a raspberry pi this fan is absolutely silent. I don't mean it's quiet I mean you can't hear the damn thing unless you got it 3 mm from your ear. Cooling is excellent 32 to 33° c on idle never gets above 35°c (95°F) on a Libreelec media system no matter what I am playing. 4K h265 h264.... Doesn't matter can't push this thing over 95 to 97° f even with an overclock of 2000 MHz on the CPU and 750 megahertz on the GPU. Using the standard can a kit black case that comes with the bundle had to chop it up and modify it a little bit to make it fit but there are plenty of case options out there that this will fit in. I have three pi fours running Libreelec in different rooms I have the original ice Tower on one this horizontal ice tower and one of the argon one V2 cases on another in the ice tower coolers are by far and away better than the Argonne one cases. The fan that comes with the argon one is garbage and it idles at 106° f compared to 90 to 91° f with the ice towers. I'm playing video on the argon one I will hit about 120 or more and I even used thermal paste on the argon case. If you're wondering if this works pull the trigger and just order it it works great and it's a great price I included a photo of the bottom because it seems like nobody ever does so you can see where the chips are going to come in contact with the bottom of the heat sink.

If this gives good cooling and I'm getting optimal temperatures while playing and emulating high demanding games on my retropie. This is really easy to set up and use but it does take away the ability of using a camera on the board's camera port. Besides that everything else is still functional and usable so if you're like me and have no intention of using the camera port this is perfect

Definitely recommend this product. Generic heat sinks with Pi running Pi-Star, temp usually hovered in the close to overheating. With the tower cooler, always running in the green (98/99F). One problem, the heat sink is supposed to be directly contacting the transfer pads but the CPU didn't touch. Had to double up the pads.

I've been running Home Assistant on my pi inside a media cabinet. With just a heatsink it averaged about 56c. After installing it a couple of days ago, I just checked temps, and it's been staying right around 25c.I also like that it sounds like a tiny little server running -- makes it feel more powerful.
