Blackice extreme..fans?

ablaze · 03-18-2002, 10:34 PM

i'm gonna get my BIX in a day or so..just wondering what kinda fans you guys recommend? one fan blowing in? or out? or one in and one out? what dya guys say?

Triton · 03-18-2002, 10:40 PM

Check my other thread on my new rig. I use a push pull method across the BIX with 2 120mm fans. They are Sunons and drive 69cfms each at full bore. However, I cut that down to about 7volts. To be honest I'm not quite sure how much air they're pushing through the BIX. However my temps are 34-37 degrees idle-load.

ablaze · 03-18-2002, 10:56 PM

saw the thread..nice rig triton!

hey why don't yo do some comparisons for us?
eg.
1 fan blowing in
1 fan blowing out
1 fan in, and 1 fan out

see which setup is better?

Cyco-Dude · 03-18-2002, 11:33 PM

well, a push - pull config is best, but if you only use one fan, you want it to suck air thru the radiator. you also want the fans eleveated off of the fin surface for best results.

Brad · 03-19-2002, 12:20 AM

make sure you get 38mm thick fans, they are quieter than a comparitive 25mm thick

Triton · 03-19-2002, 12:57 AM

Didn't know that one Brad. Too bad. I think mine are 25mm thick. But they are pretty quiet. Sunons seem to be advertised that way. What I really wanted were some of those aluminum body panaflows. But I didn't want to shell out more dough when I already had the sunons.

ablaze · 03-19-2002, 01:21 AM

ok. looks like its the push/pull thats gonna win

so how do i actually mount the fan 1" away from the BIX, without having to use some fan shroud or something..

Pinkster · 03-19-2002, 06:00 AM

brad on that what ive been wondering is that do you think a panaflo 120x38 would be better than a papst 120x25mm fan for a noise/airflow ratio...

you will have to shroud the fan for optimal performance as well. otherwise the fan would just suck air in between the gap, and not thru the radiator itself.
if you dont mind looks, duct tape and cardboard can make a decent enuff shroud.
as far as evelvating the fan off the fin surface is concerned, you can use anything. use a piece of scrap hose, use a large nut, whatever. be creative!

Brad · 03-19-2002, 04:00 PM

pabst is a better fan that panaflo, but they are both high quality, check out the spec sheets on each.

I have sunon 108cfm's 38mm thick and 89cfm's 25mm thick, the 108 is a much better fan, more air, it is directed better, and they are a bit quieter. Interestingly though, the 108's are louder at 7v, quieter at 5v, and start at 3.78v, while the 89's need 4.82v to start

Strafe · 03-19-2002, 08:23 PM

wait a minute... it was just a few months ago that everyone was saying that push/pull just created unnecessary turbulence. Did I miss something?

Triton · 03-19-2002, 11:17 PM

After mounting both fans directly to the BIX. I used electrical tape to seal around the edges. This provided me with a nice seal between the fan and BIX. So all the air that is moved does pass through the BIX.

A future mod for me will be to offset the sucking fan about 1/2" or more just to see if I can improve airflow through the center of the BIX. But I only see that as maybe a degree or two improvement at the most. Still it's more modding fun. The shroud could be easily made with thin metal or plexiglass from Lowes.

ablaze · 03-20-2002, 04:20 AM

ok..guess i'll figure something out. so whats the ideal distance the fan should be lifted "off" the BIX? 1/2"? 1"? also, i should do this for BOTH the pushing AND the pulling fan yes?

Cyco-Dude · 03-20-2002, 06:00 AM

that would be best if youve got the room to do that. the reason why you should lift the fan off the fin surface is to minimize the 'dead space' under the fans motor.
ive read that it should be lifted about 1 inch or so off the surface.

ablaze · 03-20-2002, 10:12 AM

ok, so i AM lacking in space. which is the more important shroud, pulling or pushing?

lets say if i could only shroud ONE of them..

Cyco-Dude · 03-20-2002, 10:25 AM

you might consider 25mm thick fans also.
if you only have room for 1 fan, have it sucking air thru the radiator. elevate it off the fin surface, and shroud it.

ablaze · 03-20-2002, 10:32 AM

ok..so if i had ONE fan i should set it to "pull"? ok..i thought push was more important..but thanks for the advice!

Brad · 03-21-2002, 12:38 AM

dual fans create more turbulance, which is a good thing, it will increase the heat transfer

Haddy · 03-21-2002, 12:47 AM

Built-in plenum chamber for increased performance and noise reduction. thats from the hwlabs site....i thought that meant it had a bult in shroud or something comparible?

ablaze · 03-21-2002, 01:26 PM

nope..there's no built in shroud..just 4 holes on each side for mounting..

hey guys, gimme some suggestions on making a shroud..i thought of just using a long screw to attach the fan. so its like an inch away..then tape off the sides?

Strafe · 03-21-2002, 03:31 PM

I was also kinda dumfounded that there is a gap when you put a fan on the BIX. I was thinking of taking a piece of rubber and cutting it to make a gasket or skirt that would cover the gaps.

Triton · 03-21-2002, 04:31 PM

A nice gasket would of been ideal. HW labs should sell a separate shroud/gasket set. If they sold that as an option I'm sure they could make an addition 10-30 bucks per unit. I would of purchased one at least for the sucking side.

Haddy · 03-21-2002, 06:04 PM

http://racecar12.freehomepage.com/ductpattern_s.jpg theres a shroud pattern for a heatercore.....the sizes might be off by a lil bitch but u get the general idea
