Originally I had a mini-internal fan on my Raspberry Pi 5 computer directly over its CPU, with the Pi being enclosed within a metal case and equipped with an NVMe hard drive. After a week the original internal fan started making a lot of noise. Arghhh.
So I opted for this much larger, external fan instead. I placed this external fan beneath the Raspberry Pi 5, so its perforated metal closure rested on it, directing the airflow up from the bottom and across the Pi. Note: to best accommodate this, I had to place a support below this internal fan so it would draw in maximum air at high speed, else it would suffocate.
Results: the Raspberry Pi 5's CPU cooled down from 70C to 49C at maximum workload. And every other sensor on the board cooled between 18-21C as well. One other note: I would not recommend using the fan at an angle as you can begin to hear some noise, and after a long time, I would assume bearings may pre-maturely wear out. It fits well with our furniture setup. Very happy with the purchase overall.
I had placed my AVR in an ikea cabinet and it was getting hot enough to fry eggs. Installing this fan and smart controller was fantastic (very happy I chose this over the simple speed switch option) - amp now sits at a very reasonable 87 degrees. I really like the fact it comes with a temperature probe and a that the Smart controller varies the fan speed automatically. I set one fan to draw aide in and the other two to expel hot air. I'll keep an eye on this setup but for now it's working well. The only thing I would have liked to see would be a backing plate / flange to cover the slightly ragged edges of the holes I cut (the inbuilt flange covers the front but not the back) but overall I'm very happy and am sure I've now prevented a meltdown of my gear. It fits well with our furniture setup. Assembly was straightforward.
