Good horizontale 40mm fan?

[Bobly]

Okay so we have more than enough information for 120mm fans but I'm not looking to get a small 40mm fan which I will place on top of the mosfet heatsink on my Striker 2 Extreme. The tricky part is this will be a horizontally placed fan and I can only assume a 40mm fan will deteriorate faster than a 120mm variant having a smaller rotor but I could be wrong.

Any suggestions as to maybe what fan I could look out for or ultimately would anything do?



While we're at it, Akasa do two LED 40mm fans that could be interesting, one is quite thick:

while the other is quite thin:

Personally I'm leaning towards the thicker one as I assume it will do better infront of a heatsink (though admittedly only half of the fans surface will actually be against a heatsink I think...) Any opinions on those two?

I'd go with the thinner one if space is a concern, otherwise just go with the one with the best CFM/noise ratio.

I guess these are just going to be cheap change-em-when-they-die fans anyway... Might as well go with the fat one, 6 CFM vs 5 CFM and space isn't an issue in my case :) Could probably fit a rad there in the future so a 2cm fan won''t be too much of a problem. Thanks for the insight anyway, if anything it made me wait long enough to think about it :)

i have no idea about those akasa 40mm fans but if you want cooling fans for mosfets why not get these
