MakerHawkcase with active cooling, aluminum alloy metal case with double fan, integrated heat sink, anti-rust compatible with Raspberry Pi 2B / 3B / 3B

Really smart case, fans are barely audible. Easy to install and good fit to the pi and screw holes.Big potential issue: the supplied heat pads were too thin to allow the case to contact the chips on the pi, so I had to use some other thicker pads I had lying around. I recommend buying some extra heat pads with this otherwise it's not going to be effective.

Wasn’t sure this would be value for money.The top and bottom heat sink are both nicely machined and fit perfectly on the Pi.The fans small and appear delicate, but fitting is simple. 8 of the 12 screws secure those.Choose the right thermal pads for your Pi, stick to the appropriate chips on the board. Remember the bottom chip that needs one.Remove the covering on the top side of the pad and place the heat sinks in place.4 screws secure the heat sinks with the Pi in between. Plug the fan in as shows, and the job is down.Fans are quiet. You can barely hear them.Temperature has dropped from 49.5C to 32.2C at idle. Can’t complain at that.

fits well, one of my fans is a little whiny, could use some better directions on thermal pad placement.

Solid, sturdy build with a nice finish. The main reason for buying this was for the active cooling - unfortunately one of the fans has started to create a horrible noise on operation rendering the whole point of the cooler moot. Other reviews mention the same so it doesn't seem isolated, but its out of the 30 days and there is no repair option. Replacement fan costs most the price of a whole new case.

I don’t normally leave reviews but it’s because of these I bought this item as my raspberry pi 3b+ x2 with media server and torrent downloading and seeding was over heating all the time so bought these and I’m not gonna lie to you but it really is super quiet. Even with the two running 24/7 you cannot hear the fans unless u go up close. I highly recommend for that reason and the fact with these my temp stays below 50 degrees Celsius under load.Edit 17-9-19I’ve had these fan cases for a while now and even doctord it a little to fit my 2 new rpi4. Still keeps temp below 50 degrees C and super quiet and have not failed me yet.

My pi, working in a very hot conservatory (summertime), needs serious cooling. This looked perfect. It is totally not!Manufacture and finish are fine and its a promising lump of aluminium heatsink extrusion. The pi sandwich assembles easily though I'd advise a careful check for potential shorts. Some of the clearances are close and production variations could make them closer although I found no specific problems. The 4 through-bolts and 8 fan fixing bolts are essentially the same, but the fan bolts have a shallower head to fit within the overall profile. - Nice detail, not documented, but why not just use shallow heads throughout?But this thing has some rather obvious design flaws:No physical protection for the parts which need it most: The Pi's USB and ethernet ports are completely unshrouded and as vulnerable as ever to unsympathetic handling, being dropped or dropped upon. The power port and sd-card jut out beyond the case and are also still vulnerable to catching.I'm not convinced the fans are necessary, but their inclusion makews them more so: To fit within profile, the heatsink fins have been removed from the very area they would have given most benefit! But the tight profile leaves precious little space for actual airflow. Each, already weak, fan blows air directly against a (now flat) heatsink face from where it's expected to leak out from the edge of a wafer-thin gap. It's not even a full gap, blocked on two sides by heatsink fins, and on a third side by matching air pressure from the other fan. So what the fans will mostly do is build up a back-pressure.The fans used are near silent when behaving themselves but are prone to breaking out in an annoying buzzing/squealing noise. So far this hasn't been permanent and can sometimes be cured by lightly tapping the top of the fan.As supplied, the fans must be powered from two pins of the GPIO port, rendering the GPIO port unuseable for any full port connection. A better option would have been a USB power connector, or at least the option for one. - With 4 USB ports available on the Pi, it's likely that at least one will be free.(The supplied fan connectors also break above the slim form factor which the designers have otherwise striven to remain within. A bit of a shame.)Worst of all for a heatsink-based design, the actual thermal interface to the hot bits is via self-adhesive thermal pads. I've yet to come across one which isn't essentially an insulator. I considered long and hard about how to make a better thermal connection before fitting them. With them my Pi, previously running 60-65C uncased, still runs at 60-65C (non-laboratory conservatory conditions, different but consecutive comparable days).This design decision is mind boggling! - It's not like they were limited to a simple extrusion. This one has been milled (to very nice effect) all over, so milling an extra lump or two to the correct height for the hot chips should be trivial. Then all you'd need is a nice small drop of heatsink compound and job's a good'n.This heatsink/case could should have been perfect but is let down by silly design decisions and is adjacent to useless on the heatsink front. But if you just want a stylish nice well-finished enclosure, which looks the part, then this might very well fit the bill. I still like it and I won't be sending it back but I'll be moving it to another project, which doesn't require the cooling. Still looking for a decent cooling solution. A real shame!...I feel for the designer who was forced to compromise their beautiful design in so many unnecessary ways.

Honestly can't write anything about this as it won't fit the pi 3a. It is solid and has fans which don't seem to be able to blow harder than a nats fart, other than that it's metal and can potentially cool down and protect your pi but not a pi 3a which was my fault but I can re cut it to suit another board.

Really like this case, lowers the temp great.It’s sturdy, easyish to install, got to watch the thermal links. Cable is a little too long, not instructions, but easy enough to google where it connects.Hardly makes a noise. I’d buy again!
