Taking Air Cooling To A New Level?

37 DBA though compared my just about tolerable 30 DBA tricools :(

Maybe I could just buy one to put on my Rad though.
 
did say in post #25 the noise is "offensive"

and to think Deltas are multiple times louder again!!

I think its every 3DB is twice as loud as before, so 37DB is 2 times louder than 30DB

I have seen those viper fans in a camo effect colour, I even remember one or two being sold in the MM and peeps fighting over them.
 
Headphones? You want to listen to them in stereo do ya? ;)

Stulid, the camo fans are Apaches, not Vipers - the Vipers are just yellow (which is why I haven't got any!!)
 
Diminshing returns basically, after a certain speed extra airflow just doesn't give more performance.

Say cpu temps are 55C at 10cfm, 48C at 20cfm, 46C at 30CFM and 45C at 70cfm...... whats the point of 200cfm, apart from the noise the temp is unlikely to drop below say 43C.

With airflow, enough is really enough and it becomes about the heatsink. The reason watercooling can drop temps a whole lot further is both the ability to remove the heat efficiently to a much bigger heatsink with vastly more surface area, the most important thing about that surface area is its all very close to the water tubing within the radiator, while a cpu heatsink, the bigger it gets mostly that surface area ends up further and further from the heat sources, with less and less efficient heat transfer.

The only thing silly CFM gets you, is silly noise and extremely marginal temp improvements.

Thats is true for air cooling, but completely untrue for water coolers including the all in one Antec / Corsair coolers.

Switching my Tri cool fan that is installed on my rad between medium and high reduces CPU temp by 3c. I have the rest of my Antec fans set to medium, and the one on the radiator set to high.

Sorry guys, but everyone loses compared to my fan:

I just found it in my cupboard, will install it to my Antec Kuhler 620 tomorrow permanently :)

I have four of those in a box ;). Used to run one at full speed on my older Athlon 64 X2 system. Oh, and they spin at 2,400RPM i believe.

Many many moons ago back when i used to run an Athlon 1GHz T-Bird system i used to run it with four 80mm Delta EHE fans (52.5dBa each) and one 60mm Delta EHE fan for the cooler (54.5 dBa). Even more alarming i used to have that computer in my bedroom and it ran 24/7, how i ever used to sleep i'll never know!

Somehow I dont think that a 12v fan only spins at 2400 RPM for some reason ...
 
The voltage has nothing to do with the rotational speed though? That would only effect the current draw. (EDIT: Assuming the current draw changes with voltage - of course)

I checked the YS Tech website. It's 2,800 RPM for 125.5CFM.

I got one of these in a desk draw.

Cant use it as its offensively loud, and its a baby compared to ones mentioned in this thread.

I've got 3 of those, they are very good on medium speed using a fan controller. They push more air at the same noise levels as the others i have.
