The Mini-ITX build begins.

I love how he uses cardboard to his advantage Great job Lazzer!

It's fast and easy to make a simple ducts for "testing purposes".

 

[Lazzer408]

Something dawned on me about this. I bet switching the low side like this is going to screw up the tach.

My little 60mm buddies showed up today.

These 60mm fans are my new case fans. They have PWM control.

I ordered some 4-pin Y cables from Newegg so the CPU fan header can control these case fans as well. Since the PSU and GPU both vent externally, the only thing in the case making any significant heat is the NB and the CPU. If the CPU is hot the cpu fan and case fans will both throttle up.

A few posts back I made a duct that uses the case fans blowing in to cool the CPU. I still want to try that again using these fans and DAMN can they move some air at full speed but might be a little too noisy to be the only CPU fans.

Rated Speed: 5400 RPM (max)
Max Air Flow: 26.83 CFM

Combined 53.66 cfm but LOUD.

EDIT - One of these sitting on the CPU heatsink can maintain 56-57c PWM cycling between 50 and 75% so maybe they will work as the only CPU fans. I'll find out soon enough.

How loud are those 60mm fans at 50% load?

I remember having some 60mm delta fans that ran at like 9k rpm. Moved an insane amout of air, but damn they were very loud...

Good question. I really have no way to measure it here but here's my opinions.
25% it's silent. Can't hear it across the room.
50% it's still very quiet. You wouldn't hear it over the TV at a low volume.
75% you would just hear it across the room but not with TV on low volume.
100% you will definitly hear it across the room with the TV on, unless your cranking a movie or some music. The 4850 at 100% is louder.

I have a ton of options I'm throwing at cooling. I'm sure your all saying "Pick one and finish it already!" I'm trying to balance cost, cooling performance, and noise level. I'd rather have a max of 65c that I can't hear then a 55c I can. I also want PWM control so it's up to the end user to configure the BIOS settings for PWM. So far the 'suck through blower' with PWM control is the best at everything. I have 2 blowers coming this week to try. In the mean time I'm trying a blower off an bricked EVGA 8800 to see how the PWM works with a blower.

EVGA blower BIOS PWM control set to 55c. Won't hit 100% until >65c
Idle - 55 (silent)
Load - 62-65 PWM cycling between 25 and 50% (wouldn't hear it over the 4850)

EVGA blower BIOS forced to 100%
Idle - 36
Load - 58

Lots of overhead for (more) overclocking. I need to get the E6750 out and stick a Q9550 in there.

Tomorrow (or later today since it's 2am already) I'm going to grab a Q9550 and see what I can get out of it. One of the two PWM blowers I ordered should be here as well as my 4pin Y cables.

 

[Lazzer408]

One blower came. This is a 25mm thick blower that is standard production from NMB. It will fit the chassis and I like the performance. It's loud when it's 100% but it won't need to run that fast to keep the CPU cool. It's just nice to have the overhead for things like dust in the heatsink or a customer installs the system where's there's poor ventilation or in a warmer climate.

Idle - 34c
Load - 52c

Definitely a win here. Great fit to.

EDIT - I put a manual controller on this fan just to make it silent and tested again. Load = 64c

 

[Lazzer408]

Got the Q9550. Testing now @ 3ghz

At the moment the new blower at 100% gets me...

Idle - 41, 39, 39, 36c
Load - 64, 59c, 58, 59c

The E6600 cores had only 1-2c difference between cores but this one varies alot more so I posted them all.

EDIT - Upgraded the hdd to a WD 750gb RE series.

Sequential read-112mb/s write-99.6mb/s
Random read-54.63mb/s write-81.45mb/s
Random read 4kb read-.841mb/s write-2.346

That drive along with the Q9550 and damn is this thing zippy for a SFF.

Windows 7 32bit (clean install/AVG/all updates and drivers)
Startup to desktop - 28sec
Shutdown to off - 7sec.

3dMark06/Vantage numbers coming soon.

EDIT - 3dMark06
Q9550@3ghz
HD4850 - 13,292
HD4870 - 14,899

Vantage
4870 - 9784
GPU - 9168
CPU - 12255

4 to 3 adaptor works great.

 

[Cuzza]

hey lazzer, i haven't been round here much lately but good to see you are still going with all this. blower fans are the way forward!

Hey cuzza how's it going?! How's your little build doing? Did you find a working solution for your cooling issues?

 

[Cuzza]

I think the plan I have will work, but I haven't got around to implementing it. I have recently started teacher's college which meant moving out of town, I don't have a permanent place to live here yet so most of my stuff is in storage at my dad's house where I can't work on it! That will change soon, but my workload for college is pretty big right now so we'll see what I can get done.

Did you make your own 4 -> 3 adapter or did you buy it?

Nothing to update. I just picked up a '04 WRX so I'm a bit distracted.

One solution found. Twin 60mm and a duct work great. I have some plastic somewhere to do it right. The cardboard is a bit leaky. I can probably expect a degree or two less once everything is notched out to fit. It's hotter blowing out because it's sucking some heat off the toasty northbridge but it will work that way and stay below 70c.

The only thing left to try is the Dell blower but I think the housing is too wide.

EDIT - I'll probably pick up a set of these PWM fans. 2 will get me >50cfm with PWM on high. I'll also find out how well the mobo's 4-pin can drive parallel PWM fans. One will need the tach lead removed ofcorse.

Blowing in:
Idle - 29
Load - 55

Blowing out:
Idle - 38
Load - 66

EDIT - adjusted the angle on the duct to move it away from the fans. (blowing out)
Idle - 33c
Load - 60c

That looks like the Xbox360 system with those fans, the duct and the low heatsink

I hate the boxer 4 Subaru uses. They always sound like they're misfiring. That's why it's getting an H6+boost.

CP, hit me up on yahoo messenger. Same sn.

I havent been doing much with this project. I impulsively bought a 96" 2-seat sandrail on a Michigan trip. I've been stuffing a Mazda V6 in it. Calculates out to a 0-60mph in 3.1sec and a 10.4sec 1/4mi. Should be a riot. Plus it's street legal! \/

I yanked out the POS Ford 1.6L and transplanted a Mazda KL-DE V6 into it. I still have some odds and ends to finish up but it should be running soon.
