“Fits perfectly, and is surprisingly silent for its size. But may be overkill for me. Fan is set to PWM to turn on after 50deg C and that rarely ever happens with my RPi.”
“I'm sure this fan works fine but I've decided not to use it. I brought it just in case the passive cooling of the Argon NEO wasn't sufficient. The passive cooling turned out to meet the necessary requirements, making the fan a redundant item. Two minor criticisms to make - the instructions supplied with the fan on how to vary the fan speed by changing the coding in config file did not work on my version of Ubuntu 20. I had to find a YouTube video to work it out myself (the location of the config.txt file is in different folder). Second quibble is I thought this fan would be perfect combination with the argon NEO case. However the design of the NEO case is such that you can't fit the fan directly over the CPU because of the central metal layer in place (intended for passive cooling the NEO case). If you remove this metal layer, to allow the fan to go directly over CPU, the case doesn't screw nearly shut. If you attempt to put the fan on top of the metal layer, the fan touches the top lid of the NEO case and it doesn't close properly. So either I was doing something wrong with the installation, or these two components are not a perfect match. Perhaps better installation instructions would have helped?”
“In my book this is the best fan available, with its built in copper heat sink it gets the job done. I overclocked my Raspberry Pi 4b to 2275 MHz and had it running Netflix in full HD and it maxed out at 43.7 c. Best with an Argon case but works with others. Will buy another soon.”
“Simply the best fan about, I have used many some costing more. It is compact but includes a copper heatsink. I overclocked my Pi 4 to 2275 MHz and even when running Netflix the temperature reached only 36.7 c with it fitted, 44.7 c with multiple tabs open. A bargain at £5.00.”
