Amazing Test of Fan Configurations
http://www.short-media.com/review.php?r=230
They tested everything from no case fans to 5 case fans, and the winner was the rear fan(s) only. Just amazing. -- Ed Light Smiley :-/ MS Smiley :-\ Send spam to the FTC at Thanks, robots. Bring the Troops Home: http://bringthemhomenow.org Fight Spam: http://bluesecurity.com |

Just amazing. I beat them. 2 minutes to idle from burn. Winchester at 2.4, 1.45v. I have an Arctic Freezer 64 cooler with the fan removed and an aluminum tape duct to the panaflo 80mm case fan running at 2200 rpm, blowing out. The other fan is the 120mm in the Coolmax psu running on high. I'll soon be putting in a quiet Yate Loon (from coolerguys) into the psu and attaching it to the Zalman fan controller in a cd bay. This setup can actually take care of the cpu with the psu on low and the 80mm at 1200 rpm. But not running 3d on a hot day. And it lets the hard drives up into the high 30's. But if you want to take your motherboard out and in you have to deal with removing the tape and building it up again. I'll have to do it when I put my Zalman passive heatsink on the nforce3 chip. I'll have an 80mm blowing over it onto the video card, and on the controller at a low rpm. It won't be in the front panel, but free-standing, actually strapped on a piece of foam to the bottom of the hd bay. I have a weird slow speed silencer fan there now, not on the controller, that's quiet except it ticks. Only thing is I don't know what sort of circulation I'm getting over the motherboard power regulator thingies. And my board doesn't give the sytem temperature -- strange Gigabyte oversight. But it's not eating the cpu hot air, only whatever heat radiates from the cpu's heatsink and beneath it, and from the video card when it heats up in 3D. -- Ed Light Smiley :-/ MS Smiley :-\ Send spam to the FTC at Thanks, robots.

Amazing Test of Fan Configurations
But they are only measuring board temp. I would also be concerned with hard
drive temp. For that reason I like to put a fan in front of the drive blowing in.

Amazing Test of Fan Configurations
Finally someone tested this. I've always thought that more fans just
make for more noise and dust. It would be nice if they had a noise rating for each configuration too. -Dylan Ed Light wrote: http://www.short-media.com/review.php?r=230 They tested everything from no case fans to 5 case fans, and the winner was the rear fan(s) only. Just amazing. |

I have foam on the inside of the bay cover to keep the sound in. The Barracuda IV is at 30C but can go into the mid-30's. -- Ed Light Smiley :-/ MS Smiley :-\ Send spam to the FTC at Thanks, robots.

I don't like putting my hard drive up in the 5 1/4 slots. The reason is
those bays are up higher in the case where the hotter air can accumulate. I like to keep the hard drive low. Try mounting your Barracuda low and see the difference.

The reason is those bays are up higher in the case where the hotter air can accumulate. I like to keep the hard drive low. Try mounting your Barracuda low and see the difference. Yes, I'd like to, but the lower bays are placed such that a hd fouls the motherboard connections, and air circulation would just pass under it. You've seen those cases where the air intake doesn't have drive bays in front of it. When I get my psu loaded with the Yate Loon quiet fan and on the fan controller I'll find a compromise speed where the drive is happy but the sound is quiet, I'm sure. Actually, I'm removing the Barracuda, with it's totally wrapped up design, and leaving the cooler-running Samsung, which will be quite happy with the psu at medium speed, or even low speed if not a hot day. The Barracuda will go in a usb external box. But next time I'm using an Antec P180. *That* will chill the drive(s)! -- Ed Light Smiley :-/ MS Smiley :-\ Send spam to the FTC at Thanks, robots.

Just amazing. sigh... you know there are people in labs who can actually do this kind of testing right. They've been doing it for years. They're called fan manufacturers. Companies like AT&T, IBM, HP, etc bring in their R&D boxes and get all the cooling info/testing done right. Free too, if you're buying lots of fans. They use lots of thermocouples, chart recorders, a big monster air pressure chamber, and little helium bubbles. Real noise testing to real standards available also. |

Amazing Test of Fan Configurations
Aha! This makes SOOO much sense!
If you have only a back fan (and of course your power supply fan(s)), that back fan pulls a certain amount of air *from somewhere*, which is, hopefully, the front/lower grill. And it exhales a certain amount of air out the back. Well... if you add a fan to the front, it seems almost redundant and might even cause air to circulate inside the case in ways you don't want. That back fan is already doing it's job of pulling air in the front and over the hard drives. We'll see... I've recorded all my temps. I'm going to shut off my front fan and see how it affects temps. -- Scotter Tyan Thunder K8WE Dual Opteron 252s (2.6ghz) 6 gig DDR400 RAM XFX 7800 GTX 256 w/VGAsilencerV3 500 gig SATA2 Hitachi Dual 24" Dell LCDs 550W power supply - "Ed Light" wrote in message news:A6RGf.32239$jR.4323@fed1read01... http://www.short-media.com/review.php?r=230 They tested everything from no case fans to 5 case fans, and the winner was the rear fan(s) only.
