Looking for a 120mm fan upgrade, 38mm?

I recently replaced the fans in my CM Cosmos with these in an attempt to lower overall noise:

http://www.newegg.com/Product/Produc...82E16835185004

RPM 800 RPM
Air Flow 33.5 CFM
Noise Level 8.7 dBA

They're pretty good, but now that I have a GTX 460 (the dual fan Gigabyte model) things get pretty hot in the case. After extended use (SC2) my card gets up to around 60C with GPU fans around 50%. The air coming out the back of the case is definitely hot, so I think I need more airflow, if only for 1 exhaust fan.

Right now I'm looking at: http://www.newegg.com/Product/Produc...82E16835185005

RPM 1200 RPM
Air Flow 49.0 CFM
Noise Level 20.1dBA

Basically I'd like to get some extra air going with minimal noise increase. 120x38 may be an option, but it looks like Newegg only carries high-RPM Deltas in this category. Suggestions? Or is that Scythe my best bet?

60C for gpu doesn't sound like much, my old 8800gt got up to like 85C back then when I had a tiny case and it still kept on working, I think 60C is ok.

the GT's are really too pricey unless ur putting them on a radiator or a sink.

If its an open air fan, you cant go wrong with Yate DSL.

And there less then 4 dollars each mostly.

How are the GTs any better?

The ones I linked are 83.3 m3/h at 20.1dba. GT is 85 m3/h at 21dba. Essentially the same thing, no?

Put another way, the GTs are 50 CFM vs. the 49CFM I linked. Same thing.

The blades do look different. Might cause the "different tone".
Different bearings as well. No idea about the practical consequences.
So there is more to the beef than just the numbers that you did list. Perhaps.

A peak of 60C is really nothing to spend money on "fixing" unless it is causing other problems, like excessive noise or limiting overclocking, neither of which you mention as issues.

sorry to hijack but I'm also looking for quite cpu fans. Here comes a stupid question, I have a couple 4u rackmounted cases. What size are the fans in the front of those?

My G92 8800GTS is over 60C at idle, but doesn't heat up much more on load either.

Psychic license: expired ... What brand and model are those cases?

4U is 7", so inside the case there could be room for 170 mm.

Ain't "post new thread" just as easy as "post comment"? :|

Exactly.

Hey, take our advise or don't. But like the other poster said, they are the only 120mm fans I would consider after having used them, unless I needed something with super high CFM.

Take a bass drum and play it at 20 dba. Then play a whistle at 20 dba. They do sound different, and you probably tolerate one longer than the other.

The GTs are very quiet, but they have higher static pressure as opposed to just moving a ton of air. Thats why they're good for radiators or heatsinks. The Scythe S-Flexs would be good for case fans, or the Yateloons.

IMO it's much easier to get a fan speed adjuster than to search for fans that you think will spin at the right speed/noise ratio.
That would be my suggestion.
