yesterday i gatal gatal go buy vizo 120mm fan and install to the side panel, then it started generating some "viiiiiiiiiiiiii..................................." sound . i've double checked secured the screws... i think the fan din hit the filter because it would be so much louder... any suggestion? or should i jz hentam balik the fan that came with the casing? BTW, any CM690 user kena this problem?

just remove the filter, im doing this with my CM 90cfm fan install at my side panel. Looks more "garang"

later ur hand go in there how?
the fan sucks air rite?
its the filter making ur fan doing dat sound.
too many air sucked in the same time

hmm filter to be removed... any solutions other than this? even with filter, inside the casing already infested with mosquitoes corpse and spider webs... really doubt what can happen without filter...

set ur fan to exhaust then....thats what i did with mine...and added a fan grill

minimal difference in GC temps for me.

vizo fans are loud and shaky ....

i'm sorry that you purchased it .... try buying Zalman next time

there's are only a handful computer fans actually report correct specification (decibles) and function correctly ....
the brands are Yate Loon, Scythe, SanAce (Sanyo Denki), Noiseblocker, Delta (they're loud, but they report correct), Noctua, Papst, Zalman

the rest of other brands fake their reports (decible, CFM etc) .. this is includes CM, SS, TT and those brands you can find in malaysia ...
currently only Zalman can be purchased locally, the rest of the goodies require bulk purchase


someone mentioned bout setting the fan to exhaust ... that's also an option .... but intake fans are much better due to focused cool air to the part

weird thing is, when the side panel fan set as exhaust, my hd4670 is around 50c... then now intake only 40c... difference about 8-10c

Try buying another fan grill and test again, previously I install another fan on it also, same thing happen.

Then I replace back the normal black 120mm fan.

is it the vizo starlet uv led fan ure using?i'm using the same 1 with the same casing,but i set the sidepanel to exhaust,no strange sounds and the fan is not realy tht loud to me

Added on April 22, 2009, 7:31 pmthey might be loud but NOT shaky if u know how to screw them properly,i have 3 of them in my casing and yet i dun feel any vibrations at all.the airflow is also vry high

and regarding the fake reports thg,any source?i only know so far the CM 90cfm fan is just pure gimmick but i don't think the vizo is.it stated 62.7 cfm and IMO it delivered what it should

Agree on your statement, it's true that Vizo Starlet UV LED 120mm fan do deliver up to what it stated there.

IMO, it's even greater air flow than the CM 90cfm.

It's whistling. Just like 90cfm at rear position. to solve this. use sponge as sound dampener .

For sidepanel i bought sponge type industrial fan filter. minimize the sound.

jz like hkh_88 said... removed the filter n no more "viiiiii..........." noise... looks nicer but lack safety... lol...

The issue here is about high air flow fan mount on side panel with the grill.

And it produce some annoying sound. Did you mount yours on the side panel with the grill on?

i mount mine with the grill.no strange sound also
