Has anyone done this? I want to replace my zalman's fan with a papst 4412fgl and i'm concerned that it won't fit properly <BR> <BR>It looks like it should work though?

You can probably make it fit... but what for? what are you hoping to gain?

It looks like the larger papst has a high rated airflow and lower rated dBA than the zalman at highest speed, so I was hoping maybe it would work better <IMG SRC="modules/phpBB_14/images/smiles/icon_smile.gif"> <br> <br>Since there seems to be a lack of more reliable comparisons of these ratings that say the theory is false, i thought trying it couldn't hurt? <br> <br>The larger fan would also cover more of the RAM and chipset. <br> <br>(same thing with the Panaflo FBA12G12L) <br>

I'd replace the 92mm Zalman fan, but for a quieter one. It's too loud for me, hums too much even at the lowest Fanmate setting (5V). In general, I find 80-92mm fans are about the quietest. Smaller, they whine; larger they grumble (hum, other lower pitched noise). Has to do with the size of the motor / coils / mass, I think. Haven't tried any of the 92mm Panaflos, but the 92mm Silencer from PCPower&Cooling is very quiet, much better than the Zalman. <br> <br>A simple SPL rating or measurement really doesn't tell you about the quality of that sound -- I find some fans have less bearing noise, so even if they're running faster & blowing more air & measuring say 2 dB louder, it can sound "better" (less intrusive) than one which runs slower and thus has less airflow noise but its bearing chatter a bit. <br> <br>If you need more cooling, go for the big one, I guess, or you could double up on 2 quieter fans like John Coyle did <!-- BBCode Start --><A HREF="http://www.silentpcreview.com/goto.php?t=s&id=18&a=3" TARGET="_blank">here.</A><!-- BBCode End --> Generally 2 quiet fans are quieter than 1 louder fan for the same airflow. <br> <br>What are you trying to cool?

p4/2.26 <br>I was just thinking that if the bigger one was going to be quieter and could also cool the chipset and rdram, that would be 3 advantages in its favor <br> <br>But since you say the bigger fan will probably sound annoying (I'm annoyed by the hum my 80mm vantec fans are making already), I'll believe you <IMG SRC="modules/phpBB_14/images/smiles/icon_smile.gif"> <br>
