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 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.

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.

Cooler Master Elite 100 という10年以上前のスリムケース（高さ69.6mm）にRyzen5 5600G と GIGABYTE B450M S2H に、このクーラーを取り付けて使用しました。 このクーラーのスタンドオフ（スペーサー）の高さは約11.5mm、取り付け時のクーラーファンまでの高さはマザーボード表面から約54mmでした。 ケースファンは無く、吸気はこのクーラーのみ、排気はFlex ATX 電源のファンのみという環境です。 cTDP45wで設定、室温16℃くらいでOCCTで10分CPUに負荷をかけると最高58℃で運用できたので、夏場の室温28℃でもCPU温度70℃くらいで運用できそうです。 ちなみに内蔵GPUでStable Diffusion Web UIによる画像生成連続16枚を行ってもGPU温度56℃で収まりました。 同環境で通常のcTDP65w設定にすると最高温度は14℃上昇しました。このPCケースでは厳しいですが、冷却性が高いケースだと、cTDP65w設定でも冷やせると思います。 このクーラーを選んだ理由の一つは、ソケットAM4のスッポン対策のため ProArtist IFE2 と一緒に使用したかったためです。 ==== 以下は本来の仕様と異なる使い方です。ご理解の上、自己責任でお試し下さい。==== 付属のスタンドオフは少し高いため、余っていたCPUクーラーAK400のスタンドオフ（高さ約10mm）と ProArtist IFE2 、さらに高さ調節のため0.8mm厚のワッシャーを挟んで本製品のブラケットとクーラー本体を取り付けたところ、問題なく使用できます。 ロープロファイルながら冷却効果があり、スッポン対策もできたので、個人的には満足できる製品でした。

really good for itx builds, nice build quality easy to install

タイプB製品。 他の会社のFull Copperより性能が少し落ちる。 しかし組み立てが非常に便利で簡単です。

Bought this fan to reduce the stock CPU fan noise. Seems to do the trick. It's definitely audible but it doesn't seem to have the rev noise like the stock fan. Instructions were easy to follow. Quick install. Fits great inside a mini ITX (Fractal Terra) case. Does not bump into existing components. It's nice that it's a universal orientation so you can choose which way to direct the heat. 1 star off as I would've preferred it was pre-thermal pasted. This is only a small nag though, so really a half star off. Paste is included.

For the money is on par with the much more expensive noctua models. Fantastic for the money and great on cpus up to around 100w.
