Low Decible High Cfm

[tbirdkiri]

ok my dad his having a royal **** fit,
i need to replace my delta 38 with a 80mm similar cfm fan and adapter for my sk-6,
i need links for both,
and i need to make sure that it is a quiet fan.

Watch the profanity.

Could probably find something at sidewindercomputers.com or someplace similar.

[VashTheStampede]

Low decible, high CFM.. that's a joke right? It would probably be cheaper in the long run to get some good sound absorbing material (Dynamat Extreme or cork board or packing foam/neoprene rubber.. etc) and putting that in your case instead of trying to find the Holy Grail of cooling fans.

Why not look in to ducting air to the heatsink from a large, but quiet, blower fan . . . .

[Szech]

Plycon (http://www.plycon.com) sells both fan adapters as well as ultra quiet fans.

[NuclearFusi0n]

fan adapters no worky on SK6 (clip system)

[tbirdkiri]

ummm yeah they do,
silicon and screws

[urbanski]

2cooltek (http://www.2cooltek.com/) has a nice collection of fans, with their dBa and cfm's listed.
I got a 80mm Hi output Sunon 50cfm, 40dB for my SK-6, but you can get a quieter Sunon or Panaflo.
Watch your temps, though, if you get too low a cfm one!!!

[Wicked Klown]

Why not just go with watercooling. Almost no sound at all and very low temps. PM me I have one I want to get rid of.

Or you could just try the 7 volt mod on that delta and see how it works.

Could you explain this, because I have a SK-6 and cant figure out how to put on an adapter (securely), because of those clips.

The 7V mod is easy and quiet, or fit a rheostat, I have it on my athlon (global win cak38) and it works fine and its quiet!!

Lennytiger,

what difference in fan speed do you see with the 7 volt? I'm trying to get a clear idea of how switching to 7 volts affects cfm, dba, and pressure.

[lennytiger]

I see a 1500RPM drop, also the CFM drops to 30. I'm not sure on pressure. Dba is at 36

Thanks lennytiger. What fan is that? And what percentage drop is the 1500 - i.e. what are the 12v and 7v speeds? How are you measuring cfm and dba and do you have 12v and 7v measures on those too?

thanks

nihili

[lennytiger]

I used a rheostat with mine, those are just estimates from my calculations.

[lennytiger]

this is a delta 38CFM, my 7V runs at 7.02V.

I've been looking around for a moderatly quiet fan today, also. I've mostly been looking for something under 40 dB, preferably in the mid 30s. So far, I've liked the Thermosonic Thermoengine and the Thermotake Voclano 6Cu. I'd like to use them on an overclocked athlon XP, and they claim they are capable. Every review I've read of them have said they're good enough, with the Thermoengine being a little better. They have them both here (http://www.sidewindercomputers.com/soccpucool.html) with good prices.

I am a little concerned that these won't be enough, though. They have CFMs in the 30s, which seems a little low. They are both AMD approved for 1.5GHz, though. I'd like to keep my processor from exceeding 50 degrees during a full load, as that's about where I start seeing stability problems with my current athlon. Do you think these heatsink/fans could at least keep one in the mid 40s? I have no experience with overclocking or playing with motherboards/processors/fans/cases for now, so I'm not sure exactly what to expect.

Anyone know a good site with reviews of cases/case fans? I need to start looking into that too. I'd appreciate any info so I can quit being so ignorant about all of this. :)

Oh - and right now I'm thinking of getting an XP 1600+ and putting it no higher than around 1.7Ghz. Too much?

[nihili]

THe fan and the heatsink are separate issues. Any heatsink will perform better with a more powerful fan. The two you mention are not currently top contenders, but should be adequate if combined with the right fan. The thermoengine in particular seems to benifit from a high flow fan. However you may also want to take a look at the SK6. It seems to be one of the favorites righ tnow. It's not the absolute best, but it's good and affordable.

If you check the topics in the cooling section you should find a lot of thread discussing which heatsink to buy. Also, anandtech does a periodic roundup of the available heatsinks. Dansdata has some good info too.

Where did you get your rheostat at? I searched radio shack and it came up with a 1.2 watt rheostat, is this the right watt?I would like to use one for my delta. and do you the link on how to put this thing together? thanks

You DON'T need an adaptor for the SK6 to use 80mm fans. Just turn the fan diagonally and use the SK6's provided clips to hold down the 2 opposite corners of the fan.

God! This info should be in the FAQ cuz I've posted this same thing over and over again.

Well, I tried your theory and it sounds good, but there is not enough tension on the springs to keep it properly in place.

What do you mean "not enough tension"? You must have done it wrong somehow. It's a very tight fit if you do it right. Lots of people have done it and nobody got that "not enough tension" problem. Make sure you use the short pair of clips for 25mm-tall fans and the long pair for 38mm-tall fans. And make sure the clips are pushed all the way in so each far side of each clip is touching the 2 adjacent sides of the fan.

And also, SK6 + 80mm Delta 68cfm = one of the best combo's. (bearable noise + really good cooling)

[tbirdkiri]

thnx for all the answers

[kardinal]

hrmmm there is a way to make my ys tech 50+ db fan quieter? i am very very interested :D

For great cooling & moderate noise, the Millenium Glaciator 2 is the very best. One of the very few desgins that treat the fan & heatsink as one integral unit. At under $33.75, it's quite a deal. Check out the reviews comments in Overclockers.com

The XP 1600+ runs at 1.4G and puts out 63 watts of heat. Oc'd to 1.7C, you're probably looking at 73 watts.

You think you'll notice the dif other than in benchmarks between that an 1.7? You think no other components will be bottlenecking performance? You think you can deal with the heat dissipation -- with only moderate noise? If you answered yes, to all these questions, well, go for it.

OK Im a dummy. I tried to hook up the Sanyo fan (30mm) using the 38mm clips. I now have the Delta 68cfm fan hooked up properly to my SK-6 and my temps dropped 6 degrees. However my computer sounds like a vaccum cleaner.
