92->120 fan adapter @ XP-90(C) ??

[jrw]

Anyone tried this?

Besides the obviious noiselevel gain, would it hurt performance in any way?

Would it be easy to attach?

[One_Hertz]

yeah I was also wondering this cause tornado is slowly getting annoying over weeks of use at 12v

[One_Hertz]

did noone ever try this? :confused:

What do 120 to 92 adaptors look like I just may set one up myself...

[trance565]

hmmm, never seen the adapters, but you could prolly make ur own pretty ez, just a couple pieces of metal, screw +bolt, and a drill, bam, ez as that.

@ one hertz, get a fan controller, a cheap one, doesnt need to be expensive, i used teh one that comes with my gfx card cooler, doesnt look too well made but it works, and it keeps the noise level down big time

no convenient way to mount it to the xp-90... it uses these lame little wire clip things...

You can see one here (http://www.pc-look.com/boutik/Prod_pc-look-Adaptateur-Ventilateur-092-120-mm-Bleu-Translucide__2361_en.html?language=en)...

I'd suppose with a little enginuity it could be attached nice and neat :)

Zip ties from the top corner screws in the fan to the metal fan clips should do the trick, and just attach the adapter to the bottom of the fan. This will also be eliminating a pretty big dead spot and improve cooling.

K R suprised EVERYBODY isn't doing this already?

those adaptors are a godsend =]

[trance565]

lol, if u wanted you could use mounts like the swiftech heatsinks have, and screw on to ur case holding the fan rite over the cpu :)

[cartmanea]

What swiftech mounts are you talking about? Do you mean like the Zalman fan bracket?

[S!1v3rB@cK_Dk]

I mounted a 120mm fan to my XP90 with the metal clips that was included in the package. It fits with a little force, and it has a very good grip, so it will not fall off.

Got any pictures of that? What be nice :toast:

Somebody asked about a 120-90mm adapter before, but the big problem is back-flow. That adapter doesn't look bad, but there are some adapters that will completly screw your air-flow, that one just had obstructions only a few mm into the outer area of the fan, so go ahead, throw it on there.

go to www.swiftnet.com and look at their heatsinks, the mcx 6400 (the one i have) coems with out a fan, u will be able to see the brackets, its really just 4 pieces of flat metal with holes, and a couple bends

Alternatively that adaptor might make a handy shroud to increase the efficiency of existing 90 mm fans in some instances.

Do you mean attaching those brackets to the removable side panel, so when it is in place the fan is held over the socket area? That wouldn't really be logical, you'd be better off using a bracket like the Zalman bracket so the fan is still there when your side panel is removed.

Just cut out the motor assembly from another crappy 92mm and use it as a spacer to attach the adapter to. At the same time the spacer provides easy clip mounting. Just make sure the 120mm isn't too heavy as the force will increase with distance. Use a plastic fan.

This whole big fan on small heatsink idea is, unfortuntely, not such a good idea if executed poorly.

If you do choose to do this, several things must be done for you to actually have an advantage over 92MM:

Use an aluminum 120MM to 92MM adapter, not an acrylic one.

If possible, fill up the protrusions for the fan screws inthe adapter flush with bondo or filler of choice.
If you know aerodynamics, I don't have to explain why.

If needed, use a bore'd out 92MM fan frame to attach the 92MM adapter to.

Use a silicone gasket between the fan and the adapter (aka vibration dampener) as well as between the adapter
and the heatsink, and finally, rubber washers on the screws, all of which dramatically prevent air pressure loss.

Use a 120MM fan that pushes over 80CFM, my personal 120MM fan of choice is this (http://sidewindercomputers.com/de12tfexhisp.html). :D

The only advantage I want over a 92mm fan is the reduced noise...

If the 120mm fan thus provide the same cooling capabilities as a 92mm fan due to air pressure loss, I'd be happy.

[$a1Ty]

yeah, you wouldnt see a huge performance gain by using a 120mm fan, but the noise reduction, hell yeah

Sry, I havent got any pictures, but it is very easy to mount it.. Its done just like if it was a 92mm fan. And it does indeed take a lot of the noise while still getting a little better temps :banana:

Actually, most experiments I've seen demonstrate that a larger fan with an adaptor will perform worse than the native fan, unless the adaptor is ridiculously long (like a cone).

I'll see if I can find the thread, thought it was somewhere on the oc forums.

In my own personal experience I tested an sp94 with a 92mm tornado (~100cfm) vs a 120mm enermax (~90cfm), and the 92mm tornado beat it out by 4-5c, altho was louder as you might imagine. To get the same sound level, frankly, the tornado at about 6V sounded the same as the enermax.

Here's one thread. (http://www.ocforums.com/showthread.php?t=344236&highlight=fan+adaptor)

Anyways, general rule is those standard adaptors on pc retail sites will only create big back pressure. They should work alright for fans on suck, tho.

[jinu117]

Actually, easier method would be ducting 120mm fan intake straight to the heatsink from outside of case. Who said intake doesn't have to be from rear ? :) Use that 120mm exhaust you got (if you do) duct it down to the heatsink. Benefits:
1) Reduced noise as fan now has less restriction right next to it.
2) Heatsink will get more even distribution of airflow.
3) You are taking cooler air into heatsink instead of shoving same warm case air which some are recirculating.
People reports up to 5-10c increase in cooling performance quite frequently doing this. However, probably not recommended for someone who constantly change things.
