100mm fans?

post #1 of 5
Thread Starter 
do they exsist?

ok yes i know they DO exsist but do they exsist on the mainstream computer market with a range of availability and selection??

ive only managed to find a few that were not intended for computers (connections were not proper, and the rated voltage was 24v dc, not 12v dc)
they worked as a jimmy for my old case when i needed some additional air flow on the cheap, but now im looking for somthing with a bit better quality, but i am limited to size for what i intend.


can anyone help me out here?

That's an odd size that was used when cases were still using 92mm fans so finding selection or stock is near impossible. Anyway, found one at Anartik

Scythe KAZE-JYU 92/100x25mm, 3 pin RPM, 42.69 CFM

Also, a Scythe 100mm x 12mm over at SVC if you need thinner fans, though pretty weak airflow.

thanks seems as if they put out a decent airflow

The reason im looking to find 100mm fans is because im thinking about replacing the 200mm fan on the top of my antec 900 with a 2x2 100mm array

I think that with the right amount of work it will look nicer and be more effective at moving air out of the case.

however by the looks of it i would need to get some sort of fan controller to keep the noise level tame, though this was expected.

If it were me, and the fan is working the way it should, I'd leave the 200mm there as exhaust. There is no benefit replacing with smaller fans, and will exhaust less air at the expense of more noise.

If your aim is to move more air with a control over the noise, the above Scythe 100mm fan (SY1025SL12M) might not work so well.

Its spec says it spins at 1000 rpm to produce 43 CFM with 22 dBA. With two of these, you will have 86 CFM with noise more than 22 dBA.

Comparing with your Antec 900's 200mm Big Boy, it has 82 CFM with 23.6 dBA (400rpm Low Speed setting). So, noise wise and CFM wise, the Big Boy and a pair of SY1025SL12M are just the same.

If you move up to the high speed version (SY1025SL12H - see link below for spec), it can move 58 CFM with 30.7 dBA (at 2000 rpm). A pair will move 116 CFM but the noise will be significantly higher.

If you wish, you might consider Cooler Master's 200mm MegaFlow fan (in red or blue). It pushes 110 CFM with only 19 dBA (at 700 rpm...comparing with Big Boy's 108 CFM with 26.5 dBA at 600 rpm Medium Speed setting). Similarly volume of air but much less noise.
