- IS-55 Black 57mm Low Profile CPU Cooler, 5 Heatpipes

I ordered this to replace a factory cooler on an HP Omen (desktop). After trying out a few others that didn't fit, I ordered this one. I started running a local AI (One that is offline and runs on my system.) Before this, I was hitting 90+ C for temps at 100% usage. After replacing the cooler, and adding a couple other case fans, I am now seeing very low 50C temps on the CPU! Yes, a 40+ degree drop! As for the noise level, I hardly ever notice it even running and my system only sits like 6 feet away from me. My only complaint is that it didn't offer an RGB fan when I ordered (July 2024), but that's very minor. Over all, well worth the money ($40) spent! Does its job VERY well!

I had four CPU coolers for this build and went with this one because it is the most effective cooler in this size range, fits comfortably in my Mini-ITX sandwich case with a 3080, and keeps the [AMD Ryzen 5 7600] CPU running in the 40s-50s (C) on average, 60s occasionally, and 70s at load or while gaming. It can get loud if you don't use FanControl to keep it to a reasonable RPM, but fortunately it's so effective that with FanControl you can keep it running virtually silent. The only downsides are: the included thermal paste is the cheap stuff, so maybe use something better if you can. Also the fittings included for mounting are definitely on the cheaper side build-quality wise compared to Noctua hardware. But they work, so no qualms there, I suppose. They just aren't as sturdy as the Noctua equivalents. Still, I give it 5 stars because for the size and the price it's hard to beat this cooler.

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.

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.

Great. Put in a S-300 ITX case. Motherboard was rog 650ei with amd 7900x and SP ram value gaming and 5070 PNY 3 fan. This ram was low profile and a little less than 33MM. Fit perfectly with a 1MM or 2MM space, good enough. Could only install with the cooler over the ram and not with the cooler over the motherboard inputs, one direction. It worked and keeps the CPU cool.

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.

The ID-COOLING IS-55 stands out as a highly capable low-profile air cooler, especially for small form factor and ITX builds where space is at a premium. Installation is straightforward, with a well-thought-out mounting system - particularly on AM5 - making it easy to get a secure fit without unnecessary frustration. The ability to remove the fan during installation also helps in tight cases. Thermal performance is impressive for its size. In an 8.5L chassis paired with a Ryzen 9800X3D, it maintains strong gaming temperatures in the mid-50s to mid-60s °C range, with only brief spikes under heavier shader compilation loads. Noise levels stay well controlled thanks to the slim 120mm PWM fan. Clearance is another strong point - the design allows good RAM compatibility and even helps with airflow over low-profile memory modules. Overall build quality and cooling efficiency make it a strong alternative in the SFF space, even when compared to more established competitors in larger cooler categories. For compact builds where height and airflow are both critical constraints, this is a very well-balanced solution that delivers solid real-world performance without excessive noise.

Running my Ultra 7 265K at 85-90% load in a cheap case with only aux fan that came with the case, the temps got up to about 80 degrees C with hte fan not making too much noise. as soon as the job finish, the CPU went back down to normal in a minute or two. Excellent cooler, fantastic value. I'm not sure what it could do with an overclocked chip.

Top Preisleitung Verhältnis! Mehr gibt es nicht zu sagen!

Received this product with the amd bracket missing from the packing. The screws were also not in plastic pouches. It looks like this is a used product with missing components. Absolutely unacceptable. And to discover this while assembling my PC is really frustrating.

スモールファクターのPCに使用しました。 純正クーラーはサイドフローなのでこの商品でダウンフローに改造し、天板に通気孔加工しました。 GPUも搭載してかなりCPU温度が上昇していましたがコレで良く冷える様になりました!

Produit un peu dure à monter Mais sinon parfait en performance

Excellent rapport performance prix et aussi performance taille ! Convenait pile poil pour ma config mini itx (boîtier s300, pour les intéressé, super boitier) monté sur un 5700x fait parfaitement le taff ventilo reglé sur inaudible. Au top !
