Enokay Raspberry Pi 4 Model B Fan Single fan Pi 4 Single fan

I am using this to cool the northbridge on my pc. The fan was a little noisy to my taste with minute vibrations. Unmounted the fan from the heatsink and used longer screws to remount with o-rings as vibration dampers. Problem solved and works perfectly! Adhesion and thermal transfer on the preapplied paste are as required!

This is a great cooling addition for the Raspberry Pi 4. The fan that sits on top of the CPU chip and the heat sinks for the memory, ethernet and USB chips eliminates CPU throttling due to elevated chip temperatures. Be sure to mount the fan so that the side exhaust can move air over the adjacent memory heat sink. Keep the heat sink fins oriented so that the air flows between the fins.

I bought this fan to keep the processor cool on a Pi4. I use the Pi4 on my 3d printer which does a great job with the exception that the processor overheats which down clocks and stops the print job. I originally set the fan on 3.3v an d it seemed fine but on bigger print jobs the processor still overheated. I ran it on 3.3v for about a week, then switched to 5v and was impressed that it was still relatively quiet. But that did the trick, no more overheating. However, within a few days I came out to where my printer is and I hear this loud buzzing noise. Turns out the fans bearing must be bad already as when i tapped the case the noise would change to a grinding noise. So took the Pi4 out and confirmed indeed the fan has already gone bad with only a bit over a week of use. Unfortunately I waited too long to install and use so i'm over the 30 days. Luckily it was only $10. Don't buy this, spend a few more dollars and get a better quality fan.

I received this fan today. It was in a tiny, white cardboard box. What wasn't in the box was any sort of instructions. Literally the only instructions you will receive are in the images that go with the page where one buys this item.That's it.There is no mention of why one would want to use the 5 volt mode over the 3v "quiet" mode. From two feet away, with the official Raspberry Pi case lid removed, I cannot hear this fan running. I cannot imagine anyone not in a library will hear it, either. Now allow me to learn you some knowledge :YOU DO NOT WANT TO USE THE QUIET MODE.Running full-throttle in the 5v mode, there is barely any cooling being provided. Yes, this fan does fit within the confines of the official Raspberry Pi 4 case. Right here, and right now I will declare everyone leaving a 5-star review simply does not know what they are talking about.I hooked my Raspberry Pi 4 up to a 1080p LG monitor. According to the vcgencmd measure_temp terminal command my Raspberry Pi 4 sitting at the desktop, doing absolutely nothing but displaying the desktop clocks in at 38 degrees Celsius. Remember that, kiddies, because that is our control number. I should note that is without ANY heatsinks, just pure, bone-stock Raspberry Pi 4, closed case.I loaded up a 1080p, 60fps video in theatre mode from YouTube. Very quickly the temp on the Raspberry Pi 4 rose to 64 degrees Celsius, and the Raspberry Pi 4 started throttling itself, as the video started skipping frames and rebuffing. I just unplugged the Pi and used a USB fan to blow room temperature air on the Pi to cool it back to room temperature.Time for the heat sinks.I applied all the heat sinks but the largest to the spots indicated by the photos uploaded by the manufacturer. To the processor I attached the fan/heatsink combo. I connected the power to the indicated GPIO pins (pins 4 and 6) and applied power briefly to the Pi to make sure the fan was working. Mission accomplished. Fan now connected and working, I replaced the case cover and booted the Pi.Back to YouTube. Loaded the same video. Measured the temperature at the same time index as without any heatsinks, and discovered the temperature of the Pi was... 62 degrees Celsius. Something was not right. Disconnect everything, and cool the Pi down. Double-check the installation and short of using a Quick-Clamp I can't think of any way to fasten the fan/heatsink combo to the processor any more secure than it is. Even so, I removed the fan and replaced it again. All connections solid, the Pi was tossed back into the fray.This time the Pi reported a temperature of 53 degrees Celsius. That's not an incredible improvement. It's certainly not what I was hoping for by having air cooling. I started looking at the official case. There really isn't a lot of air-sucking room to be had there. I thought perhaps removing the case lid would help matters, so I did just that.Run test again.Still getting 53 degrees Celsius. Ok, that tears it. I disassembled the Pi yet again, and removed the fan/heatsink combo. For the life of me I couldn't feel any air being moved by the fan. It wasn't until I wet my lips and moved the fan within a half-inch of my lips that I could finally feel any sort of breeze to prove the fan was actually moving air around at all.Removed the fan completely and installed the final heat sink on the processor. Dug up an old USB powered gooseneck fan I used to keep my USB ASIC bitcoin miners cool, back in the day. Not an incredible amount of breeze put out by this thing, but it would be an improvement - it would have to be - as I could actually feel air being pushed by it without being within one-half inch of it.Retest.With the lid to the case removed, all heat-sinks in place, and the fan set to about 75% power the temperature reported by the Pi was... 38 degrees. Yes, that's the same temperature as the Pi had previously reported without heatsinks at idle. The difference now was the PI was under full load, running 1080p 60fps video without any stutter, rebuffering or malfunction of any kind.TL;DR version :This "fan" barely cools the PI - certainly not to the degree being pushed by the 5-star reviews. Regular heat-sinks with an external fan that is NOT this one will see your Pi cool as a cucumber.

Great quality. Fast shipping. Works as designed. The pictures of the product has the install instructions. Just follow those...
