GeeekPi ICE Tower Cooler for Raspberry Pi, RGB Cooling Fan with Heatsink for Raspberry Pi 4 Model B & Raspberry Pi 3B+ & Raspberry Pi 3 Model B

First I should point out that the box I received had Pi 3 model B on the side label but I had a Pi 4 (worried ....)In the box was only 1 set of brackets not 2 with no label on them (worried more ....) BUT they did fit the Pi 4 as expected (I think maybe the V 2.0 of this product may have a universal bracket set now ?)I used MX4 thermal paste instead of the included sticky pads which worked well.I intended to build a fan controller with a MOSFET but it is fairly quiet and I have not needed a speed controller as yet.Also the V 2.0 fan is not just the blue led but changes colour and intensity constantly, it looks quite cool.The kit also comes with a perspex base plate which is useful and protects the board from scratching the surface it is onas you can't use any case due to height of the cooler.Now for some temperature results :-Pi 4 has no case and is overclocked with overvoltage=6 Arm_Freq=2147 and GPU_Freq=750 (so pushed to the very limit) and running 64 bit kernel. Room temperature at 23 C.When idle on the Raspbian desktop the temperature is 30 C or lower !When pushed with 'stress --cpu 4 --timeout 360' command to load all cpus to 100% the temperature at the endis only 43 C and drops back below 34 C in a matter of seconds once command ends.The whole Pi 4 is much snappier and very usable for general desktop process now.Only negative is I can't fit the 40 way ribbon cable for my t-adapter/breakout board due to too little gap between thecooler bracket board standoff's and the GPIO pins. I can however run individual pin cables across to the t-adapter which is fine as I don't need that many, never needed anything close to all 40 at any time.The best product I have ever added to my Pi.Edit: I have found that a GPIO header riser fits OK and the ribbon cable for the breakout adaptor can be attached to the riser without any issues.

I love how easy and fun it was to put together and install. It fit my 3B+ perfectly.I wasn't keen on the pre installed color changing fan so I swapped it for the included plain black one.They also provided spare screws and fixings in case you misplaced the original ones.The fan is whisper quiet and keeps the pi nice and cool.I love this tower cooler and I am going to put one on all my raspberry pi's.Would strongly recommend.

The hex stand-offs are 5mm hex body with 5mm screw thread, so the pi board is a bit lose.I had some plastic washers which fill the gap so it will tighten up nice.the heat pad might help to fill the gap but I wanted to use thermal paste.Temps are good on Pi 3+Product shows 3 wire fan.I got 2 wire fan so can't control LED colour, it rotates colour so you can't have blue or red.Came with extra no LED fan also.

I had only had my new RPi4 a couple of days and I was already causing it to hit 80 degrees (celcius) with the various things I was doing, so I needed to do something. I thought a passive case would do the trick, but I was wrong.Seeing how chunky it was and reading how successful it was reported to be online, it was a no brainer. It was pretty easy to fit, and I had no issues with it fitting snuggly against the board.The results were striking:With no kind of tinkering, the temp went from 80 => 43.With various little config changes to push the board, including pushing it to it's limit with overclocking, it remains (until this day), around the 52 degrees mark.The only time it has gone any high (around 60) was when it was a particularly warm day, but a change of environment quickly remedied it.Totally recommend it.

The product is perfect for cooling my rasperry pi 4, I used before other solutions like small heatsink fins and even an aluminium heatsink case without having similar results.With my previous case (an aluminium heatsink block all around the raspberry) the raspberry temperature was hovering around 50 degrees celsius, with peaks up to 60-65.Since upgrading to this heatsink, my temperature has gone down to ~33 degrees celsius (I attached a screenshot of the temperature graph), with a maximum of 35 degrees celsius.I haven't tried to overclock the raspberry yet, but it's clear that with this heatsink you have so much more headroom.I attached the fan to the 3v3 pin on the raspberry and it's super silent (~ 38dB - same as a good grade "Noctua" computer heatsink).The LEDs on the fan give it a "computer modding" feeling that is quite nice and captures the attention, these are automatic.The only downside (if you consider it a downside) it's that it occupies more space compared to other solutions, and it's quite difficult to find a case in which it fits. This is not a problem however If you do like me and decide to keep it outside a case. It looks so cool that I don't want to hide it away anymore :DOverall, this ticks all the boxes, It's perfect!

If you want to keep your pi from running slow or over heating then worth the investment

Absolutely love it! Looks amazing, fits really well and assembly is easy. I'd recommend using a traditional thermal paste however a thermal silicone pad is provided.The rgb led is permanently on but a black fan was also provided in the kit should that be your preference. Works on 3.3V or 5V pins so there is 2 options for fan speed and led bright brightness.Comes with a white acrylic base plate that does the job perfectly well if you don't have a case on already.Fan I find is very quiet and keeps the processor super cool, perfect for overclocking or just turning your pi into a mini pc ;)Highly recommended all round.
