using both anti-vibration fan mounts and soft fan mounts?

got some of those acousti soft fan mounts, is it worth picking up those rubber pads like these: http://www.maplin.co.uk/Module.aspx?Mod ... 4&doy=19m4 to use with the soft mounts or is that overkill?

Stick with the sticks! The soft fan mounts/sticks, mount the fan away from the case, thereby isolating the fan from the case. If you also fit the pads/gaskets, theyâ€™ll either: a/ fill that gap between fan and case = less isolation, or b/ wonâ€™t fill the gap = having no effect whatsoever.

Used by themselves, the pads/gaskets have very limited effect. The soft fan mounts/sticks are much more effective.

sticking with the soft mounts! this silencing lark doesnt come cheap, there always seems to be a "ooh i can get this and this to make it quieter!"

If you have some DIY skills silencing doesn't have to be expensive. I like weatherstripping and zip-ties to mount my fans, it isolates well, is very secure and easy to mount. and cheap. Also there's no gap between the fan and the case.

I think using the soft fan gaskets with zip ties through the holes is a better way of mounting than using the rubber sticks.
It completely stops the vibrations and there is a complete seal around the fan.
Just dont tighten the zip-ties too much...

Weatherstripping is a lot cheaper and does exactly the same thing as the gaskets, only much better.

A really cheap solution is little velcro circles. Easy to put on, easy to remove.

That works, but it doesn't seal the edges around the fan. If that has any effect in an unrestrictive system, i have no idea. But it can't hurt to have the edges sealed.

would rope caulk work(almost like a putty type deal)? or does soft foam stripping work better?

I use non-hardening modeling clay when mounting speakers in-car to provide a "tough" backing. but i dont think that may be the point here...

I think the cheapest method is the one I recommend

Blu Tack or better still UHU White Tack (doesn't harden as much as the Blu Tac).

I use four blobs (one on each corner of the fan) and use a cable tie in a couple of the holes. I don't close the cable tie - just use a blob of tack on the other side so the cable tie doesn't slide through (highly unlikely but...).

Beat that someone please

BTW UHU White Tack can be bought from Poundland.

actually now that i think about it.. the nonhardening clay may just do the trick... the way i think, it may just add enough density so that the metal doesnt resonate with the fan rpm frequency...

what do you guys think? i use the same block of clay in the car where temperatures reach extremes, so its probably safe to say the computer should be fine too.
