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 :eek: You can blow dry your hair with these

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

Careful your mobo doesn't become airborne. ;)

ProfessorFate: "what happened ?"

eva2000: "i attached 4x 190cfm fans to the motherboard/cpu and tray, and turned on the pc... the motherboard took off into the air and disappeared"

OK, this finally proves it,

Over clocking will drive you crazy….hehe :D

Your not going to run those at full speed are ya? :rock:

RH nah oc'ing will make you go deaf before you go crazy :D

at full speed they aren't that loud actually.. not like the 80cfm delta high pitch whines

So, do you plan on running them at a lower speed? You should get some good air flow even at a slower speed.

Of course you’ll need to test them out at max voltage…hehe

yeah on Thermaltake fan speed controller http://www.thermaltake.com/products/accessories/a1268.htm

high speed = 100% rpm/cfm = 190cfm
medium speed = 75% rpm/cfm = 142.5cfm
low speed = 50% rpm/cfn = 95cfm

[eva2000]

Well 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

so far looking really good.. my crappy 2.4C costa rica could never do this before until now with this 190cfm fan on high speed so far

2.4C @ 270fsb at 1.525v and it passed the first run of memtest

before it couldn't pass the first run of memtest @270fsb unless i put 1.7v in bios to it

new high for this 2.4C memtest passing at 278fsb at 1.6v

[eva2000]

Now this is crazy! I'm memtesting passing this 2.4C costa rica @ 285fsb at 1.725v in bios :eek: 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

[eva2000]

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 Eva..

[eva2000]

thanks dbwillis :)

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
max 99.9% stable oc = 270fsb at 1.75-1.8v
max unstable benchable oc = 270-275fsb
max boot into windows = 275fsb

MCX4000 + 120x38mm Delta 190cfm fan
max 99.9% stable oc = 275-280fsb at 1.70-1.775v
max unstable benchable oc = 283-284fsb
max boot into windows = 288fsb

2.4C Costa Rica 288fsb 3:2 divider

[SupermanCK]

there are all tested at high speed setting right? all 190cfm...???
doesn't the air make more noise than the actually fan at that setting?

i am looking into building a new computer and my goal is to have a very quiet overclocked system...but on air...no H20 or those other crazy stuff...so i am gonna get a case with 120mm blow holes...

[eva2000]

yup on high setting which isn't that loud.. the fan runs at 4150rpm max 59dba which isn't as annoying at all.. the medium setting at 3150rpm is best compromise very quiet
