380 -450cfm Delta power MCX4000

[eva2000]

I had ordered this stuff a while ago and they arrived today from sidewindercomputers.com Each 120x38mm Delta 190cfm fan consumes 36W of power You can blow dry your hair with these

All pics at http://www.fileshosts.com/heatsinks/MCX4000/

Zalman fan bracket screws and bolts are soooo useful







Last 2 pics show a 92x25mm Sunon 50cfm fan attached which would hover over the memory slots to cool the memory

Some pretty serious CFM there

Any left over?
hehehehe

[eva2000]

hehe.. none left over right now.. after air cooling they'll be used for a rad for water cooling for the hot summer to come

[st0nedpenguin]

That's a nice idea there with the extra fan bolted on for the RAM, I might give that a try myself.

You need to move upto toriodal fans (rat cages) to get better air pressure and cfm really though, my fans are 24watts and 380cfm... And i use 2 of them... Theyre also considerably quieter than axial fans too.

Turn them off, I can hear them all the way in Sweden

[eva2000]

toridal fans ?

lol Liquide



Just got it up and running and wow!

high speed = 100% ~4050 rpm/cfm = 190cfm
medium speed = 75% ~3150 rpm/cfm = 142.5cfm
low speed = 50% ~2150 rpm/cfm = 95cfm

on lowest speed setting these 190cfm are as quiet as a mouse but still generate enough air to keep the cpu at idle 0.5 - 1.0C above motherboard temps

low speed setting
cpu idle: 24.5 - 25C
mb idle: 24 - 25C

Aircooling a 172watt tec @ full power on an alpha, using 2x380cfm fans

[eva2000]

holy cow.. you seriously mount that on a video card

[st0nedpenguin]

Is that an 80mm Alpha or a 60mm?

[eva2000]

Now this is crazy! With this 190cfm delta fan, I'm memtesting passing this 2.4C costa rica @ 285fsb at 1.725v in bios This is the same cpu which before couldn't even pass memtest test #1-3 on first pass @ 276fsb at 1.6-1.825v in bios

running pcmark2002 @ 285fsb right now.. a whole 15fsb better oc!

[]JR[]

god no, it was just to prove you can aircool large tecs, but you really dont want to

]JR[

[eva2000]

oh i see hehe


well 2.4C @ 285fsb @ 1.725v managed to run pcmark2002 to the end but rebooted straight after





2.4C @ 283fsb @ 1.75v ran pcmark2002 fine







Remember this is with a 2.4C costa which prior to using 190cfm delta couldn't even boot into windows past 278fsb or even run pcmark2002 past 276fsb at any voltages!

Nice work eva. I was thinkin of puttin one of those monstors deltas on my heater core to see what it can do.

[eva2000]

thanks.. that's what i'll eventually use them for a rad for my first adventure into water cooling heh

[STEvil]

How long was the TEC running in that pic, JR?

I have an "86 Watt" one that does that in about 15 minutes... I am starting to wonder if I was shipped a slightly larger one than I bought.. hehe 8-)

[Illicit Tweakin]

I like the look on peoples faces when they hear 2 delta 120x38's goin wide open.

They think your nuts.

[faruquehabib]

hahahaha...i love xtreme air cooling. i love loud systems. all ya gotta do is crank up the volume and you're fine for playin games

About 2 minutes or so...

i have to say 190cfm delta fans are awesome probably close to what you'd get with water ???

2.4C SL6WF Costa rica cpu

MCX4000 + 92x38mm Sunon 120cfm fan
