most powerful 92mm pwm fan?

mymorph · 18 Apr 2010 at 13:49

im looking at modding my zalmon cnps9500 with a new fan, would like a 92x38mm pwm fan with huge output - just for the fun of it!

so far this has the highest CFM, i can find

AVC DS09238B12HPFAF
92 x 92 x 38mm
12V DC 0.90A 10.8W
5000 RPM 104.07 CFM 51.1 DBA
Ball bearing
50,000 Hrs. MTBF
PWM 4 pin connector

100CFM! XD

Will be amazed if anything is more powerful than that.

51.1 DBA?! Don't think the neighbours will thank you for that

lol - nor will me ears. i dont expect it to run at that rpm all the time, just for the experiement to see how cool i can get it.

is the copper hot to the touch when the cpu is loaded and fan on full? If not then more airflow may not make much of a difference...

my current temps are actually fine sitting at 40-45 full load & fan on full. just wanted PWM for when idling really. just curious as too how it will work out. i thought maybe could get to sub 35c??

im suprised the average pwm circuit on a motherboard can handle that sort of current.

get one of these on a proper fan controller if you want to do damage

This should be interesting

The colder the heatsink the faster the heat it drawn to it?

Azuse05 · 23 Apr 2010 at 00:12

Yes, but every heatsink has a thermal rating (in W) beyond which no extra amount of air will help i.e. heatpipes can only move X amount of heat every second.

mymorph · 23 Apr 2010 at 10:01

yes itll be very interesting to see if there is any noticeable improvement. the other option i thought was to have 2 fans push&pull but im not sure if i can get a good mount at the moment.
