Question Fans with Arctic cold and silent design?

I am bidding on a fan at EBay that is listed as an arctic cold and silent design for computer computer case. It is a brushless design / sleeve bearing with
2 x 4 pin molex connectors.


Has anyone used this? Can I simply splice the wires into the 1s the fan in the hood is connected to? Read speed is adjusted according to the heat of the computer, Thus uncertain if it will work.

What is the CFM and dB rating?

If it is an automatic fan, you'll want to avoid it especially if it will be used as an intake fan. Hood temperatures are different from computer temps, and if you are intaking air, the fan will be measuring the outside cool air instead of the inside hood hot air.

Is the temp measured with a sensor in the computer or is there something in the fan that measures it? I will be using it to blow air into the light unit. If I set it up to take air out of the fan this will be considered out taking the air?

It has 2 x 4 pin Molex connectors, which I will discard and splice into the leads of the fan in the hood.

DBA is 25.2
MTBF is 45.000 Hrs.
Fan Speed is 2000 rpm

The most important consideration is whether this is a 12 volt DC fan or a 110 volt AC fan. If the former, you need a power converter to get the 12 volts DC, so you can't splice it into the hood wiring. If you give us a link to the ebay listing it wouldn't be hard to check it out.

It is 12V DC / 0.10A / 1.2W. The fan in the hood has similar ratings.

Looks good to me! I wouldn't worry about the thermostat feature of the fan, assuming it actually has one. You can't lose by having the fan running constantly while the light is on. It is, after all, a constant source of heat the fan is dissipating.

Are you using it as intake or exhaust?

I don't have it yet. I haven't decided yet which will work better.

This is the light fixture I am putting into


There is enough room for the fan to fit inside the end. The bottom will sit at the end of the legs, which I will cover with metal strip painted with very white paint. Uncertain if I will take the end off or leave it on. It will be trial and error.

Yate loons are much better fans, dead quite and they move a lot of air.

The store linked above is top quality in the pc overclocking world, AAA quality and service.

Looks at their Reseller's rating
