A decent 40 X 40 X 10mm Fan

[MikeJRamsey]

What I thought would be a simple Google search has stumped me. I am looking for a 40 X 40 X 10mm 12v 3-pin fan to cool my Northbridge heatsink. I would like the input watts to be << 1.4 and the amperage to be much less than one. Quiet of course. And a MTBF of 50000 hours (five years). What's out there is the 35000 MTBF class. Call me picky. Price isn't that important; I don't care if it costs $3.99 or $13.99.

The closest thing that I have found is EVERCOOL's model: EC4007M12B. See here (about 7 rows down): http://www.evercool.com.tw/products/fan_4007.htm

Less than 25 db isn't great but acceptable. However, I can't find anybody who sells this particular model. I don't want to buy APOS that either fails or starts squeaking after two years. Most of this stuff seems geared to vars who are looking for a low price at volume; I want to buy one. I just want something that I don't have to worry about.

What's out there and how do I order it?

--Thank you,

H8,
Thanks for the pointer. I had looked at some of those fans earlier in my wondering and dismissed them. The Sunon MagLev was a fan I hadn't considered. A little loud but the MTBF looks about right. Reading about the technology I am curious as to why it should be so loud. I suppose I can buy a couple different types and try them out.

Thanks again,
Mike Ramsey

The higher the CFM for that small of a fan, means the faster it spins. The faster a fan spins, the noiser it is. Also Newegg has 13 different 40mm fans: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010110573%201372726520&name=40mm

Model P/N VDC AMP WATTS RPM CFM db weigh (g)

The "V1" spins faster and is noisier.

I have searched the Newegg list but didn't see anything I liked. I probably saw this Sunon but passed over it the first time because of the noise. Now it looks like the best of the bunch, noise and all.

I wanted 1 with an blue LED. So I went with this http://www.newegg.com/Product/Product.aspx?Item=N82E16835103155 I just didn't use the hearsink that came with it. It's not overly loud (must be running at close to the 25db rating) and dropped my NB temps by about 4C

unclefester,
I like your thinking.

The fan has a MTBF of 20,000 hours. I was looking for 50,000. Still, 2.2 years of continuous operation isn't bad. Plus it's cheap to replace. The heat sink makes an interesting conversation piece.

Personally I use it for a paper-weight, but I sure I'll find something to put it on.
