## Questions & Answers

**Q: what adapter do i need to connect these to my power supply? and can i connect all on the single cable**
A: I purchased the 140 mm, though I would assume they should be the same. the fans themselves are 3 pin if you are going to attach them directly to your motherboard but they also come with 3 pin to molex adapters (which I used) in order to connect them directly to the power supply. I was able to attach two fans in series to one of my power supplies molex strips.

**Q: what is the cfm**
A: 24.2CFM

Ripped from their website. 

Standard fan 80mm

Recommended for CM 690.

24.2 CFM Higher airflow to enhance cooling performance.

Silent operation at 20 dB-A for excellent case cooling.

RoHS compliance for protecting the environment.

**Q: I would like to use this fan to help cool a rv fridge. which two wires should I use to connect it ?**
A: 2 thin fans 80×80×15mm or 120×120×15mm use in front of RV refrigerator fins it will take this cooler temperature move it faster throughout  the refrigerator will keep cool.

Use Inkbird Dual Stage DV 12V Digital Temperature Controller Fahrenheit Thermostat Heating and Cooling for Homebrewing Brew Fermenter Fridge Incubator Greenhouse

**Q: Is the 92mm size a measure of the physical plastic, so that it's 90mm from screw to screw?**
A: The size is the actual outside measurements of the housing. A 92mm fan has holes on 82.5mm centers and a 120 mm fan has holes on 105mm centers. I have a Thermaltake case with room for a 120mm fan, but the widest holes are on around 93mm centers that don't fit any readily available fan that I have found except these. My 120mm version of these has a second set of holes on the output side on about 93mm centers that work in this case. I stocked up while they are available.
