80x15 mm fans?
Are there silent 80x15 mm fans? How do they compare to 80x25 fans? I'm thinking of replacing the psu fan and suspend the fan but there is no room unless I use a thinner one.

Does your case have a ledge for the PSU to rest on? If so, then just mount the fan using the EAR grommets onto the PSU casing, then put the PSU on that ledge, and screw it in as far as you can. By doing that, you have no only fan isolation, but PSU isolation as well, since the grommets would provide some isolation between the PSU/Case.
Otherwise... yah you're outta luck =[

the zalman ZM-OP1 is very quiet at 5V, just not sure if it would move enough air for a psu. i guess it would at slightly higher voltages.
I find this to be quieter than a ZM-OP1 (I have both). It's also cheaper, and you get that funky piece of metal that SVC calls copper. I'm no metallurgist, but I seriously doubt it's pure copper.
Main problem with this one is I'm not sure if quality is consistent.
Another alternative is to mod your PSU so that instead of having a 80mm blowing out, you have a 80mm on the opposite surface blowing in. If you go that route, make sure you seal all other holes where hot air might escape back into the PSU.
There is at least 1 mod (using a blower fan - Aero?) like that here in the forums.

AFAIK, the Q-Tech 300W is a Fortron variant. Yes, sometimes it gets very crowded inside but not crowded enough that you can't swap the fan. It may look impossible but it really isn't.
Some of the better Fortron variants use rubber washers for mounting the fan. you might want to consider that too.
I seriously advise against a 80x15 as the main PSU fan. They'll either push too little air and cook your PSU or will run at high speed (I know the Zalman, for one, can push an impressive amount of air for its size) but will be orders of magnitude noisier.

Bringing this back from the dead. I'm looking for a quiet 80x15mm fan, and this link just leads to the SVC website--probably they don't carry it anymore. If you could find the part for me, I'd appreciate it. Thanks.lenny wrote:I find this to be quieter than a ZM-OP1 (I have both).

If you apply a thin layer of 100% silicone caulk between the fan and the flange, you will get the isolation you want and still have room for a 25mm thick fan. For best results, apply the silicone caulk and let it set up for about 30 minutes and then attach the fan. That allows the silicone to adapt the proper shape even if not applied perfectly even. 100% silicone caulk is sold in several different sizes for multiple uses (tub and bathroom, windows, etc) and comes in several colors including clear. The most common brand is GE.
This should allow you to use a 25mm thick fan, which provides better air movement than a thinner fan (if you can find one). In theory, a thicker fan is quieter because it needs less RPM to generate the same CFM output.
You can also use nylon bolts and nuts to attach the fan. This will provide additional isolation.
Both the 100% silicone and nylon bolts/nuts are available at any good hardware store (Home Depot, Lowe’s, Ace, etc). This is my standard fan mounting technique, including for case fans.

Hi,
If you're willing to order from europe, try http://www.dorothybradbury.co.uk. She doesn't have the 80x15mm Panaflos on her website anymore, but most likely she can get them if you need them.

After looking at this froogle search, I'm guessing that it was a hard drive cooler. If you want to buy an extra one and send it my way, I'd appreciate it.hmsrolst wrote:Bringing this back from the dead.

well digikey has the panaflo 80x15 l1a for $10 - fba08t12l linkage.
or if $10 isn't enough to pay, these guys will gladly sell you a refurbished (yes, refurbished) fba08t12l for only $105!

This is the model I use. I've got about five in use various ways.....none as a HD cooler. They are acceptably quiet for me, even at 12v. I attached two to the rear of my hot-running 23" LCD monitor, and at 12v I can live with them.....They will start at 5V FWIW.

It's only $169 for a 3-year warranty, too - now you can sleep easy at night!yeha wrote:or if $10 isn't enough to pay, these guys will gladly sell you a refurbished (yes, refurbished) fba08t12l for only $105!
I remember reading that the electronics inside the fan don't work at 5v, only 7 and above, but I don't know what difference they'd make if they did.Bluefront wrote:...They will start at 5V FWIW.
A bit of googling turned up this page:

Scroll down to the 80mm x 15mm, made by Sanyo Denki. Interesting fan, isn't it? Looks a little familiar.

I have an 80mm x 15mm Evercool. Mine is extremely well balanced and starts reliably at 5v. It's very quiet for a ball bearing fan.

I see that this one has already been posted. Nevermind.

I've been trying to get an 80x15mm fan in Australia, but Atech charges $40 for shipping, and the others don't ship over here and are not answering emails to make a special case. I'd really like the Sanyo Denki fan, and was going to buy Atech's thermal fan speed controller too.
Any advice on retailers over here, or someone who could ship here?
Thanks
