## 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.

**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.

## Customer Reviews

### ⭐⭐⭐ Standard fan
*by W***E on 5 March 2022*

In spite of the high UK price. my product was noisy with a bearing which got warm in normal use. If you really need a slim 80mm fan there are few other choices, but otherwise there are in my view better options.
