IS-47-XT 47mm Height Low Profile CPU Cooler 4 Heatpipes CPU Air Cooler for HTPCs, ITX, and Small Form Factor Builds, 92x92x15mm Slim Fan, Support Intel LGA1700/1200/115X

The small form factor space has had some exciting cases that have come to market over the last few years. Some of those cases are really small -- I'm talking about the ones that are less than 10 liters in volume. Many of these have severe height limitations on the CPU cooler. This cooler compares nicely to other more expensive small CPU coolers, like the NH-L9i in terms of the way its made. I can't personally comment on how they stack up, but they are very similar in design. I chose to roll the dice on this newcomer, and it definitely performs. First, let's get out of the way who this cooler is made for. You would not try to cool an enthusiast or flagship CPU with this cooler. That means if you're thinking of an i7, i9, Ryzen 7, etc. -- This isn't for you. Those CPUs use way too much power, and as a result, they generate more heat. This cooler really shines on i3 and some i5 applications, because the peak power consumption can be low enough, that this little guy can dissipate the heat effectively. Don't just look at rated TDP either, compare CPU cooler TDP with actual peak power consumption. My travel rig currently has an i5 12400 riding in a Z690i AORUS ULTRA PLUS, and the IS-47-XT does a great job with that. With 3dMark benchmarks, on stock power settings, I only reach temperatures in the high 60s (Celsius). Gaming loads are typically a little lower. The noise levels are very reasonable with my current CPU and case setup. I opted to swap the included non-RGB fan for a 12v RGB fan from Scythe. It works great but you have to carefully screw it down as the screws go deeper into the fan and will push into the heat sink fin stack a little. I've tried both the 15mm and 25mm thick versions from Scythe and there's little difference in performance. I did seem to notice a little less noise and turbulence from the 25mm fan, but that might just be due to that fan resting against the mesh side panel of my case, effectively sealing it off. I had to get creative with finding screws to hold the 25mm thick Scythe fan, but I'm a builder and I have tons of that stuff on hand. Either way, both size fans work well on the heat sink. This cooler should fit in most, if not all, modern ITX boards between the RAM and VRM/NVMe heat sinks. One huge plus about this cooler is that it doesn't need to cover the RAM. ID-Cooling makes the IS-55-XT, which is a little larger, and can effectively cool slightly beefier CPUs. The compromise with that one is the increased height, and it will either need to cover the RAM or VRM heat sink. This limits you to non-RGB low profile memory if your VRM heat sink is chunky like the one on my board. Your case also may or may not fit the IS-55-XT I'm waiting for my i5 12600K to arrive, and I plan to try to tune it enough to tame operating temps enough for it to be my new CPU in this rig. I'll update my review once I have my final findings. If you have realistic expectations, this CPU cooler checks a lot of boxes, and at a total height of 47mm, it fits in a lot of cases.

I am trying to build an small PC with the Formd T1 case. Originally bought the ID-Cooling IS-55 but unfortunately, although that cooler handled the AMD 7600X perfectly, it has compatibility issue with the case (with the cooler overhanging RAM side, it interferes with the side bar and top fan). So I found this on the ID-cooling website while searching for alternative, and amazon has it on sale. What a surprise little cooler! When I first got my hands on it, I serious doubt that it can handle the AMD 7600X based on just how tiny it is (compared to the IS-55, it is A LOT smaller). The official website spec this as capable of handling 95W, which I did not believe to be true at all. Well, I'm partially right. At 95W PPT limit, the 7600X thermal throttled at 95C as expected, but it handled 85W PPT like a champ! At 85W PPT limit and running Cinebench R23 multicore for 30min, temperature maxed out at 88C! Although that little 92mm fan sounded like a jet engine at 100% rpm, it never thermal throttled! You can further tune down the power consumption if you want quieter operation. The fan becomes inaudible 1ft away below around 50% rpm, and quiet enough for me up to 70% rpm. I was able to undervolt the 7600X with PBO2 -20 and combine that with the 85W PPT limit, I get 95%+ of the performance compared to the 105W stock setting with a tiny cooler. I will update this review if I encounter any issue going down the road . But for now, I am very pleased with the results. There are not that many 47mm or below low profile AM5 options out there. This being the newest on the block definitely proved to be a solid entry.

Decent cooling for tiny igpu (5700g) system. Works in warmer dusty environment. Very quiet. Expecting to replace the 92mm fan yearly. Works great. Cpu can get up to 80% thermal limit if stressed but that's kind of expected. 65w chips or lower for this cooler. Great deal. Fits in teeny tiny cases.

In all honesty, I wanted to get a new LP cooler that can replace the intel stock cooler in my Optiplex size case because I absolutely hate mounting the intel stock cooler. I didn’t want to spend much so I chose this cooler as it had clearance for the case. For $35, the cooler had some solid weight and quality to it. It didn’t feel cheap as compared to the Intel stock cooler. Mounting it was easy but had a little trouble getting my screwdriver through the fans to get to the mounting screws When I first boot the PC, I was concerned about not hearing any fan noise when it was booting. However it was actually a very quiet cooler! Compared to the intel stock cooler, it was nearly dead silent! When gaming in this 9L case, it was hovering around the mid 50s compared to the mid 60s from the stock cooler! If you are looking for a budget low profile cooler for an i5 or Ryzen 5 chip, this is definitely the cooler for you. A 65w i7 or Ryzen 7 can work as well but just be aware anything about 90W may have some overheating issues!

I used it to replace a small Intel cooler I'm using on an old i5 2500K. That thing is so noisy I could really tell if that computer is on even when it's idle. It's on a small-ish case so I wanted a small CPU cooler. I've always loved the Coolermaster Hyper 212's and I used that on a couple of PCs I owned but it might not fit so I bought this instead. I think it's about time that all stock CPU coolers be like this. I suppose it's not gonna work on an overclocked system but right now on my 2500K on stock speeds it's working pretty well and it's quiet too even when I ran a CPU stability check. I remember that the stock Intel cooler (came from a different CPU, 2500Ks don't come with a CPU cooler) sounded like it's grinding itself to shreds when I ran that same check.

I bought this cooler to use in a mini ITX build with a Ryzen 5 5600x. It came with thermal paste that I did not use and some different brackets for different coolers. It was easy to install and functions as expected. CPU temperatures do not go much higher than 70 degrees under load, which is acceptable in a mini ITX build. This product has met my needs as expected and I would consider it in future builds.

I will be returning. The reason I will be returning is because I am running a SFF case with a Ryzen 5 7600X CPU. I've seen the CPU idle between 40 to 60 Celsius at max fan speed, and while running games I see it between 80 and 90 Celsius. Now, this might be a "me" problem, as when I first installed the cooler, as I was tightening it down, the bracket on the heat spreader popped off, screws and all. I did remove the cooler and reattach the bracket (tightening both, actually), but as it was kind of a pain to line up and install over and over, I did not want to chance having the bracket pop off again. I suppose it's possible I don't have it down as low as I could, but the brackets popping off speak to its quality to me. Cheap cooler, cheap experience. It's not tough to install, and I'm sure in some instances it might work fine, but my experience doesn't warrant a second chance. I'll spend money on the Noctua.

Decent enough little cooler to start with. I bought it for its front-mount system that they jocked off Noctua for to make repaste and general maintenance easier in my Inwin BP671 without needing to remove the motherboard to dismount the cooler. I also bought it assuming that Noctua's 26mm screws fit this to be able to upgrade the fan to a full-fat 25mm thick one since I had those screw from my NH-L9i, and I was right. However, there's no bottom to the holes on the IS-47-XT, and the flanges on the fan frame can bend, so be mindful of how deep you tighten those screws down into it. I'd say that as long as you don't get a defective product (I've read some reviews here saying things like stripped threads and such), the cooler sans the fan is fine. The fan is garbage, it has countersunk screws, is loud-ish and I honestly wouldn't trust its longevity. Since the screws are the main problem here, I'd say that if you want the 15mm profile, either find some 16mm screws that come with the NH-L9i/a, or find out what size and theead they are and hunt down similar ones, then toss the fan from this in the trash. Oh, and IDCooling's customer support sucks. I doubt they misunderstood that I meant the fan screws, not the AMD mounting screws. Edit: after digging around, I found that the size of these screws are M3x26mm for a full fat fan, which means you'll need M3x16mm for a slim fan. Hope this information helps.
