i can confirm the TT does come with a excellent fan pushing out over 50cfm and is pretty much in-audible!

No 50cfm fan is inaudible, especially an 80mm one. Its technically impossible, unless its 80mm thick.
Even the best 120mm fans can only push about 30cfm whilst at a low enough speed to be in-audible.
 
raikiri have u looked at the Typhoon on the thermal take website? it states the fan's specs and if you would kindly direct your eyes toward my sig you will see that i have a Typhoon!

Harris, have you read the OP? :rolleyes:
 
No matter what the specs say, its technically impossible to push 50cfm with an 80x80x20mm fan and be inaudible. Fact.

Many fan manufacturers lie about the specs, some just make it up to sound good, some use non standard meansurement methods.

Yeah thermaltake a well known for that, but harris thinks we are talking about the Big Typhoon. We arent :p
 
joe i didn't claim it was 100% in-audible but it's pretty damn quiet, imo noise levels are as a person perceives them, whats noisy to one person it's quiet to another! people pick up different levels of sound in different ways, i currently have a panaflo m1 on my Typhoon, and 2 Ys-Tech 120mm fans in my case and i don't class it as loud, yes i can hear the fans but it's not in any way annoying!

my appologies been ill the past couple of days with heatstroke, still delerious ignore me!

*runs and hides under a big rock*
 
I can assure you in order for an 80mm fan to push 50cfm its going to have to produce around 35db, which for a fan is in fact loud.
It will only be inaudible if you are deaf.
 
as raikiri kindly pointed out joe i was on about the Typhoon's fan which isn't 80mm it's 120mm! and as i previously stated i never claimed it was silent, in-audible could mean it can't be heard over the other components within a system! i.e. i can't hear my stock TT fan over my 2 Ys-Tech 120mm fan's anyways lets leave it at that as we are crapping on this guys thread!
 
Sorry, but this is the sort of tripe many manufacturers come out with, claiming their fan has a bajillion cfm and 5db, and then people come on here moaning that their system sounds like a jet engine.

In-audible means you can't hear it in a very quiet room, so the fan must be <20db.
The highly acclaimed Nexus fan does 22.8 dba for instance and must be undervolted slightly to become inaudible.

There are some fans with a slightly better cfm/noise ratio than that but no fan does 50cfm at <20db, which is the accepted definition of inaudible.

You can't go round saying a fan is inaudible because you can't hear it over everything else, inaudible is assumed to mean almost silent (<20db) unless you state otherwise.
 
i said "pretty much" in-audible, i didn't say this fan is the best thing since the chocolate fire-guard and is so silent that it makes a passive cooler sound like a harley davidson! so shall we just leave at that? I agree a lot of manufacturer's claim there fans don't perform as they claim (i for instance bought a thermaltake thunderblade fan, thermaltake claim these push 70cfm and are 17db just lies) but what i was getting at is people's perceptions of noise levels are different!
