ID-COOLING IS-55 Black CPU Cooler Low Profile 55mm Height CPU Air Cooler 5 Heatpipes 120x120x15mm Slim Fan, CPU Fan for Intel LGA1851/1700/115X/1200; AMD AM4/AM5

This BARELY BARELY fit my older b365m pro4 board with an Intel i5-9400. It too me a while to figure out the right orientation for some reason.It's cold in my basement still but it's keeping it at 23C idle. And about 40C on full load. Even in the 2u chassis.Great price. Runs very quiet. Installation and mounting was very quick all in all, put backplate on, put standoffs on, put the 2 brackets on and tighten them up with nuts. Paste the cpu and screw on the cooler.Instructions are a little lacking but all needed info IS there.My NAS is rockin' now!

Bought this a while ago and after almost a year of daily use it's still working perfectly and quiet and keeping my cpu cool. Noise is a big concern for me so for me to get temps at the max of 70c playing something like cyberpunk cranked to max in a tiny ITX case like mine, it's satisfying that it's only audible if I lean in close, and then I'm hearing my other fans.

This cooler is amazing when you were trying to keep a low profile build actually low.I ordered a few from Amazon and every single one that came in had been used and returned. Double check your shipment for missing parts. That being said I have had this fit on multiple motherboards, but you will probably have to remove your memory heat spreaders. Use a thin card and they are super easy to remove. Once that is done, it will clear easily.

I have this in a sg13bq. Running a ryzen 5900x at 60w 45A TDC 65A EDC. It is able to keep it at 65C in 27C ambient. Cinebench scores around 14000. Asrock b550m itx/ac motherboard is compatible with vrm heatsink height. I have corsair vengence 32gb. It did not fit with my memory so I flipped it so it was over my vrm heatsink. The only way this would fit on the memory side is with memory without a heat sink. Wraith stealth was running 50W at 65C where I had 65C thermal limiting the performance. It was hitting cinebench scores of 7800.The configuration I have with this case sg13bq, is intake 120mm, I am using p12 slim from arctic reversed and exhausting air into the psu. my psu is facing downward towards the cooler.If you want to use another slim 15mm fan like noctua or arctic, you need to get another screw set. I am using "Hillman 3-mm 0.5 x 20-mm Phillips-Drive Machine Screws" Item #755504 Model #127111 and I am using "Hillman 3-mm x 0.5 Zinc-plated Steel Hex Nut " Item #755591 Model #127081 as a spacer or Danco 10-Pack 1/2 Rubber Washer Model #88569 would do. I purchased from Lowes. Any taller than 20mm, and it will not fit in the sg13. The original screw set for 15mm fan is too short by 2mm. Its because the fan they provide has screw holes that are shorter than the standard 15mm fan.The good thing though, is the 25mm fan mounting set is compatible with 25mm fans. It was able to mount my actic P12 120mm and my arctic F12 120mm no problem. If it doesnt work for you, then just get a taller screw set. They are standard 3mm diameter x .5 thread pitch screws. I would assume 3mx.5x28mm or 3mx.5x30mm should work and use nuts as spacers if needed.The fan they provided is sufficent in performance, but louder than any other slim fan I have used. Quieter than the wraith stealth though. Wraith stealth had an annoying ticking sound. Also, the fan they provide has a bit of turbulance, even with the rubber insulation.Mounting system was similar to noctua. If you know how to mount noctua, it will be the same experience. I am iffy on the mounting quality compared to noctua. Noctua is top notch in quality. I didn't feel too refined to me. I feel like it was just off the line and stuck in the box. But only time will tell how well it stands up.Heatsink quality is really good. Nice finish, and very performant. If you need 57mm low height, pick this. Nothing beats it for the size except water cooling.

This works quite well, but it's time for me to vent. As I was reading the instructions, it states to remove the 15 mm fan for the AMD CPU and use the long screws to secure the 25 mm fan. My question is what? I looked in the box and the parts I scattered around, there was no 25 mm fan, the longer screws were there but no larger fan. Lucky for me I had purchased a 120 x 25 mm fan, a box of three about a couple of weeks earlier, from the same manufacture ID, and only used two of them. So I grabbed the fan I didn't use earlier and installed it. The IS-15 cooler works well and is extremely quiet, with my larger ID fan, that was not included. The smaller included fan was to be used for Intel CPU. I looked over the Amazon Description, there was no mentioned of requiring a different fan for AMD, which is not included in the box. It just states a 120 x 15 mm fan. I have a similar grip with the manufacture, I purchased another ID cooler, which I will review soon. ID's Products are good, but their communication is poor.

Cools my 5700x3d like it should on my 8L itx build. No complaints

Got this to cool my 7800x3d in my Fractal Terra case to pair it with my 4090fe. What a beast of a cpu for its size and you can’t beat it for $40. The fan does get pretty audible at max rpm’s (granted, the way my fractal Terra is configured, it has the is55 pushed up against the panel), but rarely does it hit those speeds. I wanted to try and swap out the fan for an arctic p12 slim and scythe kaze slim 120, but the former didn’t fit because the screws that came with the installation kit isn’t long enough and the latter gave out this unpleasant noise profile. Nevertheless, even at my 7800x3d stock settings, the is55 is able to cool it with my bios’ standard fan curve settings, without throttling, and WZ3 gaming at 4k/144hz, it never went above 75c. I adjusted my pbo to -20 for all cores and set it to 65w eco mode and it brought the temps down to 60c. So either way, is55 is able to hold its own. The is55 was super easy to install too! AM5 socket install was a breeze and I was even able to secure everything without having to unscrew the fan off.
