...the current fan is a 60x60x10mm, which I gather is rather an unusual size. Has a three-pin connector (yellow, red and black wires).

I don't know if anyone has a specific recommendation for a fan this size, but...are the thinner fans generally louder than thicker ones? I could look at building a deeper enclosure for mine if I had to.



Thanks for any input.

EDIT:

Also, is it possible to tell from the fan's connector what its voltage is? This one doesn't have any printing on it. Thanks...

There are very few options for 60x10mm fans, and i dont have any experience on them, maybe something like Cooljag Everflow 60mm x 10mm Fan (126010DL).

OK, well...what if I were to build a deeper housing for it?

There are more options on the 25mm thickness, but not sure if it would be worth it, 60mm fans tends to be noisy as they need to rev more to move air, but up to you, i would just try the fan 10mm and see from there.

OK, maybe I'll give that a try. I know this is probably a lame question, but can I make a good guess on the voltage of my fan, based on its connector? I'd like to make sure that new fan is the same voltage rating.

Update: I did in fact order and install an Evercool. It's no quieter than the stock fan. It was worth a try, but as Abula cautioned me, it seems to be a challenge to get a really quiet 60mm fan. I'll have to give this some more thought to see whether I can put something else on there.

You may also try Noiseblocker fan, XR1 or XR2

Edit : but they are 25mm thick...

How about 15mm thick fans ?
I used a PAPST 60mm * 15mm fan and it was very quiet but airflow was not great. It might be worth a try if you can get one.

If I go with anything thicker than 10, I'll have to make a new bracket to hold it in. If I'm going to do that, I might as well go to a full 25mm, no?

Yes ! There is absolutely no room behind the fan right now for anything bigger than 10mm ... ?

Not enough room for anything bigger, no.

Yesterday I put the original fan back in after cleaning the dust off with compressed air. It seems a lot quieter now (maybe just my imagination), so I'll probably run with it as is. Building that new housing is going to take a bit of doing.

If you have a dremel and don't mind having no fan fan grill on the fan, cut out the grill, it can make a really big difference (depending on the kind of grill you have).

OK, thanks, Frenchie.
