ARCTIC Liquid Freezer II 280 - Multi Compatible All-in-One CPU Water Cooler, Compatible with Intel & AMD Sockets, Fan Speed: 200–1700 RPM (Controlled by PWM)

Runs silently with great cooling performance and a stealthy look. Feels premium. Relatively easy to install. Idle temps for a i9-14900k are around 28-30C. At full load those temps can rise to 80-85C. Overall very happy with the purchase.

Pros:-Great performance and noise levels, outperforms any other AIOs I ever used, from both Corsair and NZXT.-The default fan controls are decent, you can just leave the fans plugged through the pump without worries.-Thermal compound tube included, which I much prefer over "pre-applied compound"-Installation is easy and straightforward for AM4-Good valueCons:-Installation manual is missing some steps, like the part where you have to screw brackets on the pump block, since Installation is quite instinctive I still figured it out on my own but it should definitely be clearer in the manual.-If the vrm capacitors are too close to the cpu socket on your specific motherboard, space may be a bit tight for the installation of the mounting.I did not knock off a star since I consider those cons to be "minor inconveniences".Random issue:Since this cooper's fans are controlled through the pump, it seems like my motherboard freaks out if I only use the "AIO pump" 4 pin connector and the "cpu_fan1" connector is left empty, basically refusing to boot.I solved that issue by connecting one of the fans on that connector.However, I consider that to be a motherboard issue, not an Arctic issue, just mentioning it for those who may have the same issue.

Consistently rated as a top performer by PC experts. The fans are very quiet even when providing max cooling. Under Prime95, this AIO kept our Ryzen 9 5900x under 75C at close to 100% CPU usage. Extremely well built. The only drawback in our setup is that we couldn't top mount install it. It's very thick and wouldn't fit with the RAM in place. Works great, nevertheless, on the front of the case.

Después de haber leido y visto reviews de este producto me animé a comprarlo aunque la estética no me pareciera la mejor para mi gusto; en general la critíca especializada lo califica como unas de las mejores soluciones de disipador de cpu actual, más aún por el precio bajo y los excelentes resultados en todos los apartados.Apenas llevo unos días de uso pero hasta ahorita el rendimiento es excelente , mejor que el NZXT Kraken que tenía anteriormente. Lo tengo instalado Push/Pull y las temperaturas muy bajas! el cpu fresco, como si nada, de los mejores! MUY, muy silencioso, hasta con los abánicos a máxima velocidad silencioso, me soprendio! cumple con todo.La apareciencia es de gustos, nada de RGB ni cosas del estilo, para unos no se les hace lo mas bonito y a otros les gusta. Los materiales se ven de calidad, fácil instalación, tubos un poco mas largos de lo acostumbrado que puede llegar a ser muy util para algunos.El único detalle que tuve no es del producto es sobre el envío; llegó un día antes todo bien en eso, pero estaba como si lo hubieran abierto (la caja del AIO, la caja de Amazon estaba cerrada), muy extraño. No sé si como viene importado de USA en aduana abran las cajas para ver qué es. Eso sí, todo nuevo y funcionando, al final no hubo algún problema.Muy recomendado!

I don't write a ton of reviews; however, I rely on them heavily. It's been a headache trying to find a AIO for my specific application as it seems what I am doing isn't done much, so I wanted to share this.I have a Be Quiet 500DX case, Ryzen 5600X CPU, RTX 3080 FTW with hybrid kit installed.Since I have a hybrid kit, my optimal mounting point, the top, was not available. I front mounted a Corsair 240MM AIO, but the heat it was dumping into my system was killing my GPU temps.To give you an idea of what I am working with, my PC is a gaming PC first and foremost; however, when I am not gaming I use it to mine. I mine with my GPU and CPU so it creates a lot of heat.I've tried air coolers and other AIOs but nothing was fitting the bill. Since I mine while not using the PC, having the PC quiet is huge for me as the computer is in my main bedroom.To get proper air flow and keep temps low, I wanted intake in the front, with top and rear exhaust. As with most cases, and since my top was occupied, this left me with going with either a rear mount AIO or air cooler. I tried many air coolers, Mugen 5, Noctua UHA, Noctua UH-S. Nothing was fitting the bill.I tried Be Quiet's 120MM AIO - temps were high and the pump oddly enough was loud.Too much time that I care to admit was spent researching. I found out Arctic's Freezer II 120MM has a thicker rad. Thicker rad, more heat being able to be expelled I thought. Well it can, with a catch.Since the rad is thicker, yes it can expel more heat but you need either a high pressure fan or two fans in push/pull. I am running all Noctua NF-A12x25 fans in my case (amazing air flow with almost no sound) so I stuck it on the cooler in push. Getting great thermals. No OC'ing and while CPU mining peaking at 55C. Air coolers were in the 61C-65C area. Be Quiet's 120MM AIO was at a tad higher at 67C. After messing around with slim fans, push pull configs, and trying to get the best performance to noise ratio, the sweet spot for me was a pull configuration with a single Noctua NF-A12x25. TO NOTE: I have two of these kits for two pcs I built in my house. Both kits (bought 6/2021) shipped with REV. 2 mounting hardware. You'll want to email Arctic and tell them your processor and ask for the REV. 4 mounting hardware. It dropped my temps 6-8C. Why not get the most for your money?You'll also want to consider swapping the fan that comes with the cooler with a Noctua fan. The P series fans are great, but at certain RPMs they make the weirdest groaning sound. Look up the P12 series fans on amazon stand alone purchased and you'll see what I mean. Noctua's NF-A12x25's are just smooth sailing no matter the speed (within reason).The pump is also PMW controlled so you can dial in the performance/noise ratio as you wish. I use a mother board header and an app called Fan Control V82.Side Note: There is a small VRM cooler on the pump. It's a tiny fan that spins and shoots air up into the VRM heat sink to cool it. If your case has good air flow, you won't need this fan. I would disconnect it. It isn't stupidly loud, but as with most tiny fans it makes noise. You must unplug it PRIOR to installing the pump on the CPU. You'll see the tiny connector that powers it under the pump.Lastly - I used Kryonaut for all my testing. If you want the most out of this cooler, since it's thick, run a push/pull configuration. For the optimal ratio, run a Noctua in pull and all is good.TL:DR - Great cooler. Best 120MM AIO I tried. Thick cooler so it's great. Beats air coolers I tried. You'll need to email Arctic customer service if you didn't get a rev. 4 mounting kit to get the best possible thermals. Consider swapping the fan it came with for a Noctua NF-A12x25. You'll want to do push/pull to get best thermals since it's thick. Disconnect tiny fan prior to installing to keep noise down.Value for money is great.Mounting system is 3 stars since I had to email Arctic CS, wait a week for them to reply, then wait 3-4 days for the package.Noise level minus 1 star for having to disconnect the tiny fan. It's pretty annoying and kind of useless.
