Akasa Slimfan | PWM Case Fan | 80mm PC Fan | 4-pin Cooling Fan | 80 x 80 x 10.8 mm | Black | Suitable for HTPC and Slim System | AK-FN076

I use Akasa slim fan to replace GTX 1650 low profile verson's GPU fans.The fans are connected to motherboard's fan controller, and fan speed curve is adjusted based on CPU temperature, but mosly flat between 25% to 30% until 90C CPU temperature then it will climb up to 100% from there.It is very quiet and inaudible around 25% to 30%.GPU temperature stays below 80C for my use on heavy gaming usage.I have just one Akada slim fan blowing air onto 1650 LP's heatsink, but I am planning to add one more Akasa fan to see how much more it can help. This works very well and I like the quietness of Akasa compared to Noiseblocker's rather loud 80x80x15 fan.

This review is for the 80mm fan.I bought this to mount in the side panel of my home-built Pi4 miniPC to help keep the case well ventilated with ambient temperature air. I'm running the fan at a fixed voltage of 6v and it's barely audible from my usual seating distance from the miniPC, yet still shifts plenty of air for my purposes.The fan is equally happy to start at 5v and has such a low power draw at this voltage that it would be perfectly safe to power it from the +5V and GND pins on the Pi's GPIO header. You won't get a huge amount of air out of it at 5v, but it will still fix hotspots from stagnant air in an oversized Pi case.Further down the line, I intend to PWM the power to this fan from a 12v supply via a buffered GPIO pin and write software to link RPM to reported Pi core temperature on-the-fly. I'm grateful to now have a fan in this thing that didn't break the bank and opens up further modding opportunities in the future.If you're in to silent cooling under light loads, ie, when just watching movies on a PC media centre that doubles up as a workhorse when needed, this just might be a suitable fan for the job if you're limited to 80mm.I'll report back if the fan fails for some reason in an unusually short period of time but, so far, it gets a double thumbs-up.

I've bought a few of these fans so far, and they seem to die fairly easily, within 6-12 months of use.This is disappointing, as they're otherwise good, but there's basically no other choice when it comes to a fan as slim as this at 80mm length and width when you're limited to approx 13mm thickness at best.No idea what hours operation is, but I'm pretty confident they sit around 7,500 hours, likely less.Really disappointing to be honest.

States that it suitable for HTPC. No, I don't think so. Bought 2 fans, one was faulty and the other too loud. Had to remove them because the noise was annoying.Update. Can't find any other 18x10mm pwm fans. May have to give this another try and use rubber isolation mounts. Been experimenting with speedfan and can reduce the cpu fan to 590rpm (I can't hear it) so this may be another option to reduce the noise of the case fans.

if you adjust this fan at 1500rpm it moves a nice quiet amount of air to the gpu in a aercool micro atx slim fits nicely in there and cheap if you adjust the voltage to 6v it will sit happy there

Used as an side intake in my case to replace stock Zalman brand fan that failed, this fan is just too loud, easily louder than every other fan in my case combined, in terms of function it works fine, but that's completely overshadowed by the helicopter drone that occupies my living room every night.
