The ultimate in airflow to noise ratio, iXtrema Pro Quiet Fans are the only fans in the industry to be designed with silence and optimal airflow in mind. Smaller, domed motor hub, larger, more dramatic fan blade sweep area, no other fans on the market come even close in performance! There might be fans that offer more airflow or lower noise levels, but when it comes to a balance between the two, these fans can't be beat. Now available in a thermal controlled version, it comes with a 300mm long attached thermistor so you don't need to fiddle around with a fan controller! Simply mount the thermistor close to a heat sensitive component and the fan will speed up and down based on the temperature it senses.

frequently asked questions

1. I just installed my thermistor fan - why isn't it spinning?
First, check to make sure a full 12v is being supplied to the fan. Many motherboards have a fan throttling feature on the 3-pin fan connector to lower the fan speed when the system is not under full load, this provides a voltage less than 12v which is outside the operating voltage of the thermistor and defeats the purpose of having a thermistor fan in the first place. If there is no way to disable the motherboard's fan throttling feature, plug the fan into the power supply directly with the included 3-4 pin converter cable to ensure it is getting the full 12v.



The fan's thermistor serves to control the fan speed so be sure it is not connected to a fan controller. The first few days or weeks, the fan's thermistor needs to heat up sufficiently to speed up and break-in the bearings properly. The thermistor sensor must get sufficiently warm enough to spin during this process, we only recommend placing the thermistor along the base of the CPU or GPU heatsink as the thermistors need at least 40°C or 104°F to get the lubricants in the fan motor to spread evenly within the bearing housing. Once that takes place, it should operate as designed. There is a very low defect rate for this fan so make sure to follow through with the correct procedures outlined here to get your thermistor fan working properly.

2. What is the wires with the black tip on the thermistor fan?
This is the thermistor, which is an electronic component that adjusts resistance according to its temperature. As the black tip heats up, the fan should speed up accordingly. Place the thermistor as close to your heat source as possible so the fan can regulate its speed based on the temperature of the component. Do not cut it off, the thermistor fans are not designed to work without the thermistor probe.

3. At what temperatures will the thermistor fan spin?
Upon properly breaking in the thermistor fan motor, it should start spinning, albeit very slowly, at around 25°C or 77°F, which is roughly room temperature, and will speed up gradually to its maximum speed at around 80°C or 176°F, just a little higher than the maximum continuous operational temperatures of most processors on the market today. Ensure the fan blade is properly seated in the motor by checking to see if the fan blade is flush with the fan frame as the fan blade might pop out during shipment. The fan blade on a variety of our IXP fans are designed to pop out for easy cleaning purposes.
