## Description

Review: Great budget high pressure fan - A good budget option, especially if you can find it on sale, great for use on radiators if you are water cooling. Significantly more powerful than the dirt cheap generic ones, provides good airflow, strong pressure, with minimal noise. This replaced a cheap Chinese (I think thermaltake or thermalright?) exhaust on a 120mm radiator and it did make a small but noticeable improvement to my pc temps. It seems to be well built, with the plastic seeming strong, stiff but not brittle like cheaper alternatives. In terms of design it’s basically the same as every other fan, easy enough to install, the pwm and aRGB leads are a decent length which always helps - although I still needed to use extenders, this did make cable management easier. The PWM and RGB both work the same as every other fan I have, worked on both my motherboard headers and hubs, no software issues in terms of controlling speed and colour. This is for you if: - You only need one fan and you want RGB. I’d primarily recommend it for an intake or use on a radiator for watercooling due to the high static pressure. Maybe consider other options if: - you require multiple fans then you will often find better value in other products that come in multipacks, especially the Arctic P12. - you don’t intend to use the RGB, there are far better non-RGB options at this price point. At the end of the day I give it 5 stars as it’s a great product at a reasonable price and has no notable problems, however this comes with the caveat that you should shop around first as there will often be better value out there depending on your individual requirements.
Review: Worth the price for high end case fans that look great - I sit right next to my rig so I wanted high end cooling performance from my case fans with low noise and I can say these fans check that box in a big way. I set my fan curve in the bios so they run at 33% constant (silent at my seating distance of right next to the box) until the CPU hits 65 degrees and in most games 33% speed is enough so that the CPU never gets hot enough for the fans to spin up! Big win. When I put on a proper stress test and the fans do spin up the temps drop quickly and under sustained 100% load I have never seen the CPU or graphics card go above 70 degrees. The fans ARGB looks fantastic and is dimmable, the attached photo is from setting "Music" mode in MSI mystic light where the light pulses in time with the music. Your milage may vary depending on setup but I have found these to be excellent fans.
