120 mm case fan over alpha

Ozzman · 02-22-02, 10:58 PM

hey guys what do u think would work better.. taking off my 80 mm fan and leting my 120, 130 cfm fan blow right in front of it.. or is it better just to leave my 80 mm fan on my heatsink and leave the 120 mm fan over it?? i tryed something out and it disapointed me..

i put my 120 mm fan behind a 80 mm fan blowing in and the 80 mm fan did not push anyone air in then it was before

thats why im asking this Q.

Consider an analogy of pointing a water hose at your mouth (work with me here

). Your mouth can only take in so much water at a time no matter how much water the hose can put out.

I really come up with some stupid **** sometimes.

um not to seem rude man but that did not really answer my Q.. all i got from that was that i should also be venting the air out which i alrdy knew..

Well for me i didn't really have much success using a 120mm 130cfm fan, true while it pushes a lot of air and at the same time makes a lot of noise, i saw little temperature decrease, however when i made an air duct and let the hsf fan pull air directly from the outside of the case(there's a number of ways to arrange that) i saw a drop of 3 to 4 degrees C.

Let me re-phrase. The 80 can only take so much air in at a time, no matter how much air you throw at it from another fan.

Ozzman · 02-23-02, 12:13 AM

well what if i take that 80 mm fan off and try to duck the 120 to it.. how would that be? i mean i can always just use the 80 mm as intack and take my crapy 80mm and use it as pulling air out..

P.S i am loving turin this fan around though and using it as a fan formyself as it is geting a bit hot here now that its almost summer.. dam which one comes first my pc confort or mine HMM PC!!

i should just order another..

well for the ducting, if you have a blow hole either put some flexible ducting tubing(about 4' diameter) and put one end over the hsf and one end over the 120mm, that or just at the blow hole, if you dont have a blow hole then just put it over a case fan or something, i have it setup like that for a few systems over here, it works pretty well for me.

Ozzman · 02-23-02, 12:27 AM

ok first off im moding my side panel in front of my heatsink to put the 120 mm fan there. so the fan will be not to far from the heatsink.. and the case fan will be a little bit below the heatsink which i dont think should be a prob.. so do u think this would give me better results i mean im going from a 48 cfm y-tech to a 130 cfm fan.. also where do i get this ducking tubbing?

Revx · 02-23-02, 12:31 AM

it'll give you more air flow, you'd hope that'd give you better results, and the ducting tubing you should be able to pick up at hardware stores, i got some up at menards

Ozzman · 02-23-02, 01:48 AM

hmm i will try it both ways.. thanx

Revx · 02-23-02, 01:50 AM

np, happy modding!~

Ozzman · 02-23-02, 02:36 AM

yeah

is right as this is my first real mod job my only other has been cuting out the little dots over my blowholes so i can put a grill and get more air in.. but i think this will be harder LOL

Sonny · 02-23-02, 02:43 AM

How about having 2 of those YS-Tech 120mm? You need one for cool air to come in then have the other one ducted over the Alpha sucking the air off of it.

Ozzman · 02-23-02, 02:36 PM

first off its not a y-tech 120mm its a y-tech 80mm at 48 cfm.. my 120 mm fan is off name but at 130 cfm.. i would do that but i think that might to much power... i just need to find a way to duct this sucker.. hmm what does the ducting tape look like and whats it called at a hardware store?

muddocktor · 02-23-02, 02:59 PM

One other thing you could try with your alpha is to have your fan blowing into the heatsink instead of sucking air off of it, like I run my Swiftech. Then, with the 120 mm fan blowing outside air right into the fan on the alpha heatsink, you might get better temps. Just be sure that you take off the shroud underneath the fan if you set it up to blow air into the heatsink because it traps air and causes restriction to airflow. This is something you can try pretty fast and cuts out having to run a duct from the hsf to the 120 on the side of your case.

Revx · 02-23-02, 03:08 PM

at menards the ducting stuff was called just that ducting tubing

Ozzman · 02-23-02, 03:49 PM

it is blowing onto the heatsink.. but i did not take off the shroud.. will now though..
