Need a 80x38mm Fan

post #1 of 3
Thread Starter 
I need an 80x38mm fan. 92mm would be too big, and 80x25 is too small (i have space for wider, not bigger).

It needs to be a quiet fan, however I have no problem undervolting it, like running it off 5v or 7v (can you run fans off 7v? doesnt that hurt the psu or something). It will always be at a constant speed so no need for fan control.

This fan will be used to cool my bitfenix recon fan controller. With 2x 140mm yate loon high blue led fans on each of the first 3 channels, the mosfets for each channel get so hot that the superglue is melting off and the heatsinks on them are drooping, even with added chipset heatsinks.

Thanks. I dont mind undervolting a high speed fan or anything here, just dont know what to get (and running at 50% of 4k rpm still isnt quiet).

what you are asking for is a contradiction in terms. a thick fan is typically designed for high static pressure. with high static pressure, the fan is typically designed to be high RPM. with high RPM comes loud noise.

I understand your desire to have a quiet yet high static pressure fan, however 80mm is a "retired" size so it's unlikely manufactures will spend the time to design a new 80mm fan for that purpose. BUT, if you are only cooling off a fan controller...... a regular 25mm thick fan is more then plenty cooling for that purpose.

on another thought, maybe you should send xbournex a PM and see if there is anything he can do for you. it's always nice to have our very own bitfenix rep hanging around the board smile.gif

A 25mm fan is not sufficient, I have an 80x25mm fan and tried it. Furthermore, an 80x25mm fan at 2K rpm is loud, I want a fan that is totally quiet here, and I can't use a 120mm, so wider is the only way to go here. I understand my options are likely limited to undervolting a high rpm fan, but I am totally okay with that, just that undervolting a 4K rpm fan doesn't make it quiet so it has to be like 2K rpm at max 12v.
