In need of a good mid range 92mm fan

[SparkedFire]

Hi,

I need to get a good midrange 92mm fan. By mid range I mean one that puts out about 65cfm~70cfm. I dont want something as loud as a tornado, but I want more airflow than standard 35dB fans. I know that I could get a tornado and get a fan controller but that is more money Than i want to spend. I am using the fan to keep my CPU cool with a Swifty MCX478-V heatsink. Please let me know what your thoughts are. Thanks.

66.3 cfm, 40 db.

I saw that fan but it would be $18 after shipping. Thanks for the input though.

Here's a good one: http://www.sidewindercomputers.com/92clearulwit1.html

64.15 CFM @ 34.3 dB

Hey, thanks. that looks like a good fan. i'll prolly get it.

I'm silly. Didn't even think about that product line...the 120mm version of that one works the same way, I put it in a customers computer, and it was pretty decent.

Oh, check shipping at sidewinder too....newegg has it for $5.99+4.00 shipping....

bgmicro.com for fans - has several 92mm units. See "Hot Deals" section - panaflo for $3.19 or $2.65Q10.

I wanted to bring this back from the dead with a couple questions from somebody who has never used a fan larger than 80mm (except for one 120mm intake fan). I'm looking for a fan to put on top of an SLK-948 (the A64 Thermalright heatsink) on a non-overclocked A64 3400+.

First off, would I be better off going 92mm than 80mm? Logically, I would but are there good enough fans out there to justify it?

Secondly, what is generally a good performance/noise range for 92mm fans? In this thread, the best one (in my opinion) suggested was lavaman's suggestion of the one at 64CFM@34.3dB. I think that same fan (on the "low" setting) at 47CFM@28.0dB is much better. Personally, I'd like to stay below 30dB, preferably 25dB, ideally 20dB. Another option that I've seen at SVC would be 38CFM@20.0dB. Even though this sounds weak, it would essentially be inaudible. Do you guys think it would be enough on an A64, non-OC'd?

Any general advice would be appreciated.

Just about any fan would be good enough for a non-OC'ed processor. The heatsink does most of the work.....a minimal amount of fan airflow is needed though.

So you're saying you think the 38CFM fan would be good enough?

Also, a general question about 92mm fans - Is the "dead spot" in the center on the larger fans larger than it is on 80mm fans?

 

[daba]

Yes, the deadspot may be larger.

Yes, I am using a 78CFM fan right now, a downgrade from my 119 cfm tornado (both are 92mm) and it shows a 1-3C difference.

There are some reviews on the web comparing 80 and 92m fan sizes on the TR SLK947u (essentially the same as the 948) and they actually state that an 80mm does a better job but not by much. For a little bit quieter fan but still good cfm, I stuck with the 92mm. BTW: I chose a Panaflo 92mm.

There are these at http://www.bgmicro.com for 99 cents each!:
92x92x25mm(3.62x3.62x1"). 12Vdc, 160mA, 2000RPM, 37.50CFM, and 25.0dB-A. FAN1060......
92x92x25mm(3.62x3.62x1"). 12Vdc, 220mA, 2500RPM, 47.20CFM, and 27dB-A. FAN1061.......
They also have a 92x92x38mm, 1.5 Amp Delta fan that probably isn't very quiet (5100 RPM) but could help turn your case into a hovercraft...

My take is that 80mm are slightly better for spot cooling albiet a little noisier, however the 92mm will help to get some air flow around the ZIFF socket - like Mosfets, ram, or NB.

They also have what they say is a 48V fan. How the hell you gonna power than inside a PC without a transformer and some dangerous work? And WHY would somebody do that?

bgmicro.com isn't primarily a PC parts vendor - they are an odd-lot electronic parts vendor. So you will often find their fans will have a non-standard (for PC work) connector or no connector at all (like the 99 cent-ers above). It's up to you to determine if what they have will be useful to you. But for 99 cents, one can afford to take the occasional flyer - who knows, that 48 volt-er may work if you connect it across the +12 and -12V leads - that would be 24V across the fan. You'd have to check the mfr's site to see what the working voltage range is.
