![]() ![]() If you just want balls-out pressure, then yeah, those Circle fans might get it done, but not everything in computing is about balls out. There's a huge gap between that and Corsair, but there are fans in there like Rosewill's Hyperborea, Cryorig's QF-120 Balance or Arctic's 120mm PWM fans that fill it at different price points. It's also not going to last nearly as long as they claim. "4-pin and 3-pin" connector means it's a 3-pin and they include a Molex connector. That thing's going to be a Space Shuttle. even their sp fans dont have this much static pressure as these cheap fans.ġ9dBa my ass. now i dont see a point to go with high end corsair fans. ![]() like high end corsair sp fans are less air flow and static pressure then these cheap fans. This fan will be less noisy becaus it runs at lower rpm but also pushes more air. Such a fan would probably work less well for you, if you compare it to let's say a fan that works at maximum 1500 rpm but does 50 CFM at that rpm. Those CFM values are most often measured at maximum rpm, but that's a point where the fan would be very noisy.įor example, you could have a fan with 100 CFM at 3000 rpm, but only 30 CFM at 1000 rpm, where you may have the fan running most of the time, with rpm controlled automatically by the motherboard. So you have to keep this in mind, and you also have to keep in mind how much noise the fan will make at its maximum rpm. It may have an advertised CFM value that's much less, let's say maximum 40.60 CFM (depending on rpm) instead of 50.90 CFM in the case of a case fan, but it will be much less affected by obstacles and obstructions, it will never drop to as low as 20-40 CFM. it's tuned to work well and push air through narrow places, through fins of a heatsink, the honey comb of a radiator, through grills and meshes. The other type of fan is static pressure optimized fan, which is designed the opposite way. So such a case fan could have 50.90 CFM (depending on rpm), but if you put it near something that obstructs movement of air (like a radiator heatsink with lots of fins close together, or a case with very small holes), the actual performance could drop to something like 20-40 CFM ![]() Simply put, the fan blades and the motor can only achieve that amount of air flow, if there's minimal stuff resisting the air flow. So, it will run fine with just the regular wide grills or round or hexagonal holes in the case, it's optimized for that, but if you put a cooler or a radiator for a water cooler in front of it, the performance drops. Mostly, a regular person will be dealing with case fans and with static pressure optimized fans.Ī case fan is the kind of fan that you put on the case, and which doesn't like obstructions around it. There are two major types of fans and several minor types of fans. However, just this number alone doesn't help you. so in the most basic way possible, a fan with a higher value will push more air through the case. The value simply refers to the amount of air the fan can push, and it's measured in Cubic Feet per Minute of air. That value is useful to know but only meaningful when you use it in combination with other technical properties of the fan. ![]()
